Readers’ wildlife photos

April 19, 2024 • 8:15 am

Today’s photos come from reader Bill Dickens, whose notes and IDs are indented. You can enlarge the photos by clicking on them, and don’t miss the eclipse photo at the bottom.

I’ve been camping at Flamingo, Florida in the Everglades National Park. April is a good time of year to visit with warm temperatures and before the rains arrive and turn much of the coastal prairie into mud. (The mosquitoes though are a constant.)

Here are some wildlife shots taken along the Coastal Prairie Trail – a 13-mile round-trip along a historical trail once used by local cottonpickers and fishermen. It’s now a part of the Everglades National Park. The trail winds through an open prairie of succulents and buttonwoods both leaved and dead, presumably from constant inundation by flooding.

It was the dragonflies that are the real star at this time of year. Swarms of them.

Plus a bonus shot taken of the eclipse. I drove from my home in Florida to the Texas Hill Country to view it from Tow, Texas. The weather was cloudy most of the morning leading up to the eclipse. Then the cirrus clouds were headed one way, lower-level clouds the other and five minutes before the eclipse it cleared and stayed clear.

The Wildflowers were out in the Hill Country and this makes it a pretty time of year to visit.

Loudest sounds ever

April 16, 2024 • 1:00 pm

Here’s a fun video with a range of sounds from an alligator to the loudest sound we know of, which you’ll have to watch to find out—and you’ll want to. (I have heard a white bellbird, and it was LOUD!)

There’s a wallet commercial from 3:00 to 4:00, so you can skip that minute.

I cannot vouch for any of the information given!

Reader Don McCrady sent some lovely photos of the eclipse (I thought readers would send ’em in en masse, but it didn’t happen). Don’t captions are indented, and you can enlarge the photos by clicking on them.

I thought you might like to show your readers some photos from this past Total Eclipse.

I flew down to a spot near Lampasas, Texas. Unfortunately, we had some issues with the clouds, but we did have sporadic clearing that allowed me to get some fairly good shots.

Here’s a shot from the partial phase as the moon encroaches the sun, here about to cover up the huge sunspot numbered 3628. This sunspot was easily visible to the naked eye through our eclipse glasses. (Even the Trumpanzees I was with were smart enough to wear them when looking at the eclipse.)

In this shot, the totality is just beginning and we can see Bailey’s Beads. These are the last vestiges of the sun as they become eclipsed behind the mountains and valleys of the moon’s surface, and are one of the most beautiful phenomenon to photograph during the eclipse.

Finally we have a shot near the end of totality showing the huge solar prominences, again visible to the naked eye.

These images were shot using a Canon EOS R5, a Canon RF100-500mm extended all the way to 500mm at f/8. Partial phases were shot through a mylar solar filter, and the totality was shot with no filter.

Readers’ wildlife photos

March 20, 2024 • 8:15 am

Today we have a batch of cool astronomy photos from reader Chris Taylor. Chris’s captions are indented, and you can enlarge the photos by clicking on them.  His captions are very good, and I highly recommend enlarging the photos to see things like nascent comet tails and the moons of Jupiter, which are very clear in the enlarged photo but harder to see on this post itself.

Not exactly wildlife, but I hope these might be of interest. All of these photos were taken by me from my own property, apart from the first one.

Starting off with our own galaxy, which we see as the Milky Way. Having lived in both the Northern and Southern hemispheres, I have to say that the part visible from the south is much more impressive than the north, so I will show some of the highlights.

The first photo is looking south across the water of the Coorong, a long coastal lagoon on the east of the Great Australian Bight. The Milky Way is visible right down to the horizon. The brightest star in the middle of the photo is Alpha Centauri. This, together with its near neighbour Beta Centauri, form the pointers to the Southern Cross, Crux.  The long axis of the cross points towards the southern celestial pole, which is out of the frame of this picture.

Taken from my own backyard, the next photo is a closer look at the Milky Way in Centaurus and Crux. Alpha and Beta Centauri are at the bottom right of the frame, with the Southern Cross to the right of centre.  Easily visible in this shot is the Coalsack, a dark nebula where dust is obscuring the light from more distant stars. In indigenous culture, the dark areas of the sky formed constellations as well as the bright stars. In some groups, the Coalsack was the head of an Emu in the sky, but in others it was the head of a hunter. Also visible as a bright fuzzy star at the bottom left of centre is the globular cluster Omega Centauri.

Focusing more closely on the constellation Crux, the Southern Cross now, this photo shows the constellation in more detail. The Coalsack is at the bottom, with the brightest star Acrux at the edge of the dark area. There are another four bright stars that make up the kite shape of the cross, and which are represented on the Australian flag.  At the bottom of the photo is what appears to be another bright star. To the naked eye this seems rather dimmer, and it was given the designation kappa Crucis. But it is in fact a cluster of about 100 young hot giant stars.  When its true nature was realised, it was given a new name, the Jewel Box cluster. It is a beautiful sight in a telescope.

Seen from my home latitude, the centre of our galaxy passes straight overhead at times.  This next photo shows the Milky Way in the constellations of Scorpius and part of Sagittarius. Once again, alpha Centauri is visible as the bright star just over the roof of the house. Below and right of centre is the bright red star Antares. The Milky Way is very wide and bright in this direction and is crossed and split by many dark lanes of dust, but there are also many bright clusters of stars.

A closer look into this region of the sky shows some of the clusters and nebulae. On the left side of the frame are the bright stars of the “tail” of Scorpius, and left of centre are two open clusters named Messier 6 and 7 (M6 and M7).  These were catalogued by the french astronomer Charles Messier in 1780s who was searching for comets, but made a catalogue of objects that could be mistaken for a comet. M6 is the brighter spot left of centre. It is a cluster of about 150 hot blue stars, plus one red one.  The colours of the stars can just be made out. M7 is smaller and fainter below centre. On the right are two areas of nebulosity.  The brightest one can be seen as a fuzzy spot surrounding a number of blue stars.  This is the Lagoon Nebula, M8, a giant cloud of interstellar gas and dust shining by reflected light from the stars embedded within the nebula.  It is in the region of 5000 light years from earth. Close by is M20, the Trifid nebula.  These nebulae are areas where stars are forming from the hydrogen gas making up the clouds.

The last picture of the Milky Way is centred on the eta Carina nebula, as it rises over the corner of my house. Eta Carinae is a binary system of two (possibly more) stars. The primary is one of the most massive and most luminous stars known; it has a mass of over 100 times that of the sun, while its luminosity is as much as 4 million times the Sun’s.

Our galaxy is accompanied by a number of smaller, satellite objects.  This includes the two Magellanic Clouds. These are named for the explorer Ferdinand Magellan, who referenced them in his writings, although he was not even the first European to describe them. From my home, the clouds are easily visible, looking like spots of the milky way that have become detached. In fact, they are dwarf galaxies in their own right. The Large Magellanic Cloud is the largest of all the satellites, and it is now classed as a Barred Spiral; the bar and at least one spiral arm can be seen in this photo. It is about 160,000 light years from Earth. The bright spot at the centre is the Tarantula Nebula, an enormous area of active star formation.

Also satellites of our galaxy are the Globular Clusters. Globular clusters are collections of anywhere from tens of thousands to millions of stars that are packed into a dense spherical agglomeration due to their mutual gravity. These clusters are then able to orbit the centre of the galaxy as a single unit. Omega Centauri, which we saw in a previous photo, is the brightest one visible from earth. Messier 15 is another of the clusters catalogued by Charles Messier in the 1740s. This one is in the constellation of Pegasus and being away from the plane of our galaxy has many fewer stars close by. In my photograph the individual stars that make up the cluster – there are well over 100,000 – are not individually, but form a fuzzy halo around the central condensation of the cluster.

Moving closer to home, here are some photographs of objects in our own Solar System. The first ones were taken on 01 May 2022. Before dawn on that day, I got up to record the close conjunction of the two brightest planets in the sky, Jupiter and Venus as they appeared only 0.2 degrees apart – half the diameter of the Moon. The pair made an incredible sight, far outshining anything else in the sky as they rose over the hills to the east of my place.

But also on this day was another event – five of the planets were visible in a line in the eastern sky. At the bottom are Jupiter and Venus, higher up towards the centre is Saturn and the red planet Mars in at the top of the frame. The fifth one was Neptune, halfway between the bright planets and Saturn. But it is just visible on the photo as a couple of blue pixels, you have to look really hard to find it!

The last photo is zoomed in to Jupiter and Venus.  Three of the Jovian moons are visible, at the top is Callisto, closer to the planet is Io, and on the other side is Europa.

I also managed to photograph two of the wandering comets. First is Comet C/2021 A1 aka Comet Leonard. This photograph was taken in January 2022 when the comet had already passed the closest to the Sun in its orbit, and a long though quite dim tail had developed. This comet was found to have had a hyperbolic orbit, which meant that the orbit was open and the comet would never return to the inner solar system. As it happened, it never got that far out from the Sun. As it rushed through past the inner planets, the nucleus of the comet broke up, and with the heat from the Sun evaporating more of the ice and other volatile material, the comet vanished from view in March 2022.

Another reasonably bright was Comet C/2022 E3 or Comet ZTF. On the morning of 11 Feb 2023, it passed between the Earth and Mars, when I was able to record the event.  Mars is the reddish blob at the top of the frame, very overexposed, while the comet is bottom centre. There is a small tail forming around the core of the comet which appears green in this photo. That green colour was the result of Carbon C2 molecules evaporating off the surface of the nucleus. As the sunlight energises the molecules, they emit light at this frequency, which gives the characteristic colour.

Uncrewed Moon landing this afternoon

February 22, 2024 • 9:15 am

A “soft” landing of an uncrewed vehicle, built by NASA in conjunction with a commercial company, will take place this afternoon: 5:30 4:24 p.m. EST Jim Batterson gives the details and links where you can watch/hear it live.  This landing has hardly been in the news, but it certainly deserves our attention.

NASA/Intuitive Machines -1 Landing on the Moon Thursday Afternoon

by Jim Batterson

NASA, in collaboration with Intuitive Machines, is scheduled to soft-land an uncrewed payload near the Moon’s South Pole at 5:30 4:24PM EST this afternoon [RESCHEDULED].  If successful, this will be the first U.S. soft landing on the moon since the final Apollo mission of the early 70’s.

The mission was launched last week on a Space-X Falcon rocket from Cape Kennedy and, after several successful mid-course maneuvers is, as of this morning, orbiting the moon just 57 miles above the Lunar surface.  About an hour before the planned landing, a series of onboard rocket motors are scheduled to fire and take it out of orbit to a steady one meter/secpmd touchdown on the Lunar surface. The lander will take photographs, make soil measurements, and carry out scientific experiments.  In carrying out this mission, U.S. capabilities in space are extended to a commercial company as a part of NASA’s efforts to support more robust launch and landing capabilities by the private sector and to test and validate—on uncrewed missions—new technologies that can be used in the Artemis human crews to the moon program.

As a part of NASA’s return to the moon for a planned permanent presence, the NASA Artemis Program is developing a heavy, crew-rated launch system.  Many of us watched a major uncrewed launch in that program a bit over a year ago as a huge rocket sent an Orion capsule, which will be used to fly and land a human crew on the moon in the next few years, around the moon and back to Earth with a successful splashdown and recovery.  It is my understanding that a post-flight review of the capsule’s heat shield showed excess sublimation (melting and conversion to gas) over what was expected and that resolution of this issue and other abnormalities may delay the crewed Artemis 2 launch and circumlunar trajectory currently planned for Fall 2025, which of course would impact the crewed Artemis 3 launch—one that will carry a crew and soft-land them on the Moon in Fall of 2026.  A Wikipedia listing of the currently planned Artemis Program missions through the mid-2030’s can be seen here.

This current mission, IM-1 (Intuitive Machines 1) is the second in a series of uncrewed Commercial Lunar Payload Services (CLPS) missions that support the development of technologies to be incorporated in the Artemis crewed missions.  CLPS is a NASA program that, as its name implies, enlists commercial vendors to build, integrate, and operate compact, uncrewed space missions to prepare hardware on a fast pace parallel with the development of the main Artemis Mission crewed landings on the moon.  The idea is that using several commercial vendors creates capacity and know-how more quickly and cheaply than doing in situ testing of new space technologies.

The first of the CLPS series, Peregrine One, experienced a failure after launch last month.  The next scheduled launch after IM-1 will be in the Fall of this year and will be operated by commercial vendor, Firefly Aerospace.  This current mission, operated by the commercial vendor, Intuitive Machines was launched early last Thursday morning and is scheduled to soft-land near the South Pole of the Moon this Thursday afternoon.

As of 0830 EST this morning, the vehicle is in a circular orbit 57 miles above the moon. About an hour before the planned 1730 EST landing on Thursday afternoon, retrorockets will elongate its orbit to 67mi x 6 mi with the 6 mile high point being just above the landing site.  When the orbit reaches the 6 mi altitude point, another retrorocket firing and braking will be started and the vehicle will drop down to a soft landing in the region of the South Lunar Pole with touchdown expected at 1730EST. . . if all goes well!  Live updates are provided at the Intuitive Machines mission website, where there’s a nice write-up and link to live coverage of landing, coverage that should start about one hour before the expected 1730EST touchdown on Space.com at the site below:

One last thought:  One factor prompting this U.S. project is a bit different than the main cold-war driver of the Apollo program in the 1960’s.  Then we had a single competitor, the USSR, but that was seen as a competition for technological success of a democracy versus a Communist dictatorship.  After World War II, nobody else had the economy and technology to attempt a feat like a manned moon landing.  Today there are five nations that have hit the moon: China, Russia, Japan, India, and the U.S.  (Only the U.S. has actually landed humans on the Moon.) It turns out that there are concerns about any of these nations claiming possession of locations and minerals via landing there.

The total solar eclipse on April 8

February 18, 2024 • 1:00 pm

Here, from NASA, is the path of the total eclipse that will take place on Monday, April 8, so you have about six weeks to prepare. (You did know there would be an eclipse, right?) And that means making sure you’re in a place you can see it AND that you have special dark eclipse-viewing glasses. I was excited to see that it’s coming near Chicago, though I should really go to Indianapolis, where I lived as a child.

Below is a map from the NASA site giving all the details you need to know, including the path of totality and when totality is reached. You can download the map in larger format here (see “download” at the lower right of the map on the page) or watch the video at bottom, which goes over the path of totality.  My favorite part of such an eclipse, besides the darkness at noon, is that the birds go nuts and start singing because they think it’s twilight.

From NASA:

The Monday, April 8, 2024, total solar eclipse will cross North America, passing over Mexico, the United States, and Canada. The total solar eclipse will begin over the South Pacific Ocean. Weather permitting, the first location in continental North America that will experience totality is Mexico’s Pacific coast at around 11:07 a.m. PDT.

A map of the contiguous U.S. shows the path of the 2024 total solar eclipse stretching on a narrow band from Texas to Maine.
The total solar eclipse will be visible along a narrow track stretching from Texas to Maine on April 8, 2024. A partial eclipse will be visible throughout all 48 contiguous U.S. states.

The path of the eclipse continues from Mexico, entering the United States in Texas, and traveling through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. Small parts of Tennessee and Michigan will also experience the total solar eclipse. The eclipse will enter Canada in Southern Ontario, and continue through Quebec, New Brunswick, Prince Edward Island, and Cape Breton. The eclipse will exit continental North America on the Atlantic coast of Newfoundland, Canada, at 5:16 p.m. NDT.

The site also has a table about when the eclipse starts and ends in major cities in the U.S.

Scientific American proposes policing the language of astronomy to make it “beautiful and elegant”, as well as “inclusive” and non-triggering

January 7, 2024 • 9:46 am

Oops! Scientific American did it again, this time with an op-ed that could have been ripped from the pages of The Onion.  As is so common these days, the piece proposes that we change the language of science (astronomy in this case), since some of its terms are bad in four ways:

a.  They are violent, sexist, and triggering

b. They are not “beautiful and elegant” like astronomy is, but grating; and they are “not kind”

c.  They are non-inclusive, presumably helping keep minorities out of astronomy.

d. They are untruthful and distort astronomy

In my view, none of these claims holds up, for the article is all Pecksniffian assertion with not a shred of evidence. Author Juan Madrid assumes the role of a bomb-sniffing dog, snuffling the field of astronomy for linguistic mines.

Click the headline below to read and weep, or find the piece archived here.  The author is identified this way (my link):

Juan P. Madrid is an assistant professor in the department of physics and astronomy at the University of Texas Rio Grande Valley.

The piece begins by describing a collision that will take place, 4 to 7 billion years hence, between the Milky Way and its closest galaxy, Andromeda.  Immediately the word “collision” is seen as triggering. One of Madrid’s students described the future collision instead as “a giant galactic hug.” But the person who sent me this link added this comment:

My wife says that if Andromeda doesn’t want the Milky Way to hug her then it’s interstellar sexual assault.

Indeed! But Madrid hastens to instruct us why using “collision” is not only grating, but misleading:

The kindness, but also the accuracy, of the language my student used was in sharp contrast to the standard description we use in astronomy to explain the final destiny of Andromeda and the Milky Way: “a collision.” But as astronomers have predicted, when Andromeda and the Milky Way finally meet, their stars will entwine and create a larger cosmic structure, a process that is more creating than destroying, which is what we envision when we use the term collision. A galactic hug is scientifically truthful, and it’s led me to believe that astronomers should reconsider the language we use.

First of all “collision” doesn’t mean “destroying”, but simply two objects hitting each other. In this case, two galaxies “collide”, but their stars are spread so far apart that they’ll simply merge into one big galaxy and star will not hit star.  You could say “merge” instead of “collide”, but that also implies that perhaps the stars will absorb each other.  If you want to convey the idea that “nothing gets banged up,” then, Madrid suggests using “galactic hug”. He actually wants astronomers, their classes, and their textbooks, to adopt this new, kind, and romantic term. (There are, of course, more salacious terms that could be used.)  But they won’t be because they sound dumb, and in fact “galactic hug” is just as inaccurate as the other terms, for “hug” implies that there is some mutual enfolding, when in fact, the entities merge and do not remain separate, as humans do when they have a (temporary) hug.  When Fred and Sue hug each other, they don’t merge into one person. . .

And so Madrid, combing the literature for other terms that are jarring and, he says, misleading, finds more, as of course he would. (You can do this in any field of biology, chemistry. or physics; all you need is a sufficiently diligent Pecksniff). I’ve singled out Madrid’s instances of bad language below by adding my own links, and putting those words in bold.

For instance, in galaxy evolution we invoke imagery strikingly similar to what you would expect if you were eavesdropping on Hannibal Lecter: words like cannibalism, harassment [JAC: no instance found],  starvation, strangulation, stripping or suffocation. There is a rather long list of foul analogies that have entered, and are now entrenched, in the lexicon of professional astronomy. We have grown accustomed to this violent language and as a community, we seldom question or reflect on its use.

Strangulation is a particularly cringeworthy term in astronomy, referring to the decline of the number of stars born in some types of galaxies. This is a vicious crime where most often the victim is a woman; the perpetrator, a man. Yet, we use this word mindlessly to describe a slow astronomical process that takes millions of years. Under certain conditions, some galaxies use up or lose the gas that is the primordial ingredient to form stars. When that happens, galaxies make new stars at a lower rate. But these galaxies do not die or suffer great harm. They will continue to shine and will live their natural evolution.

This is but one of many examples of violent language in our field that actually describes something gradual, slow and perhaps even gentle.

Madrid was savvy enough to impute misogyny to one of these terms: “strangulation”, giving some woke heft to his thesis. But if you look at how the terms are used, only someone who wants to be offended would be.  Moreover, they are not inaccurate. “Starvation“, for example, refers to something that cuts off the flow of gas that galaxies need for new star formation. I don’t find it inaccurate at all. In fact, none of these terms are inaccurate—what Madrid really objects to is that they are “triggering” and “unwelcoming”. He tries to sell his campaign to deep-six these terms as being “untruthful”, because he doesn’t want to look like an ideologue, but I’m not buying it. Also he allows “explosion” for the creation of a supernova, in most cases he finds this language “needlessly vicious and [promoting] inaccurate connotations.”

In short, Madrid finds this language triggering, for that’s the only explanation for why we should avoid this kind of “vicious” language.  And, as he says below,

The use of hypercharged words in our field ignores the fact that this violent imagery can trigger distress in colleagues who might have been victims of violence.

But there are two points to be made here. First, as I noted in a recent post, giving the relevant studies, “Trigger warnings don’t work” and can even cause more trauma. There is no evidence that using this sort of language somehow harms the students. In fact, the remedy for those who are traumatized by certain words is not to avoid exposure to them, but to learn to not be upset when you are exposed. There is therapy for this.

Second, as is so often the case in these screeds, Madrid gives no examples of how the “bad language” upsets people. He should be able to produce at least a dozen cases on the spot, like “Jane got upset and left the class when she heard the word ‘strangulation'”, or “Bob reported Professor Basement Cat to the university for using the term  ‘cannibalism’ on the astronomy exam, which, he said, made him think of the Donner Party and prevented him from completing the exam.”  In nearly all of these language-policing articles, there is a surfeit of outrage and a dearth of examples or evidence of harm.

But Madrid circumvents the lack of evidence and simply suggests ways that we can censor this language, again pretending he’s interested mainly in scientific truth:

To shift toward more welcoming and truthful language in astronomy, scientific journals can push to change the currently accepted language. The referee, or the scientific editor, can ask the authors to consider more appropriate descriptions of the physical processes involved. Referees, editors and editorial boards can step up to enforce scientific accuracy and stop the use of violent, misogynistic language that is now pervasive. This is a call for scientific precision. The use of hypercharged words in our field ignores the fact that this violent imagery can trigger distress in colleagues who might have been victims of violence.

“Can”, “could have”, “might have”. Where are the examples of this? The sweating professor gives none. And isn’t it amazing that the more accurate language is always the kinder language?

And, as expected, Madrid manages to drag race, inclusion, and diversity into his discussion, even though none of the terms above have anything to do with race. And this belies his faux concern mainly for scientific accuracy:

As astronomers, we must strive to create a more inclusive and diverse community that reflects the composition of our society. Valuable efforts to provide opportunities for women and minorities to succeed in astronomy have been created. However, by many metrics, the progress made towards gender equality and true diversity has been painfully slow.

We must listen to the new generation of astronomers. My student showed me that while some astronomical processes can be intense, the universe revealed through astronomy provides us with the most fascinating sights known to humankind. Like many other young scientists, she thinks that when we explain astronomical phenomena with wording and phrases that share our excitement and appreciation, it also encourages others to join in and wonder what else we can discover together.

The universe is beautiful, elegant and ever-changing. Astronomy would be wise to follow its lead.

And so, in the end, we see that this kind of misguided effort, concentrating on words rather than science itself, is part of the corruption that has entered science via DEI and its ideology.  What we have is one more attempt to control thought by controlling language.

There is no evidence that minorities and women are being kept out of astronomy because they don’t find its language “inclusive,”, though that’s really the thesis of Madrid’s piece.  But the very idea that this thesis is true is laughable. Promoting the idea that galaxies hug each other is not going to bring people pouring into astronomy.

Once again Scientific American, trying to ride the woke bandwagon, has fallen off the train. Blame not only the author, but the editor, who actually approved this nonsense.

Readers’ wildlife photos

November 4, 2023 • 8:30 am

Today we’ll have a mélange of photos that have accumulated over the past months from readers who sent in just a couple of pix. The captions are indented, and click on the photos to enlarge them.

From Jon Alexandr:

I’m not a biologist, but I do occasionally like to take photos of plants and animals, including “bugs.” Because I favor its handy small size, I’m still using an old, first-generation iPhone SE (2016 or 2017), so it’s not “professional” photography. Still, I think the attached impromptu photo of a “grasshopper” in a wood pile next to my house has a certain presence, which is maybe amplified by the lighting, shapes, and textures.
The grasshopper’s body was just slightly more than an inch long, I estimate, not counting the extremities. Location is San Francisco East Bay, Contra Costa County.

From Bryan Lepore, sent October 29:

 I spotted what I think is a tree frog, genus Dryophytes, today. Middlesex county, MA.She is about the size of my thumbnail and has a very long jump span. Usually, I see what I think are Leopard frogs (genus Lithobates) jump like that but they’re green. Maybe she’s a brown variant, or a differeny frog.

Two animals photos and an architecture photo from reader joolz:

 Two of my photographs from the Oceanographic Museum, Monaco 2023.  Taken through glass.
Lion fish [Pterois sp.]. Oceanographic Museum, Monaco 2023. Didn’t take a photo of the info.
Longspined Porcupine Fish – Diodon holocanthus. Info on sign: “At the slightest danger it inflates its body, pushing its spines outwards to protect itself. The fish of the Diodontidae family are toxic and unfit for human consumption. In Japan, where they are eaten in sushi, a special licence is needed to cook them.”

Queen Hatshepsut‘s Temple at Deir El Bahri, Egypt. Taken from a hot air balloon decades ago.

Hatshepsut was very powerful and took on the role of Pharoah. She wore the pharaonic regalia, which includes a false beard, so trans activists claim she was transgender, but there is no basis for this assertion. She just wore the standard regalia that all pharaohs wore. Her stepson Thutmose III had her name erased from monuments and she was unknown for centuries. Thankfully her legacy as a female Pharoah was restored when the hieroglyphs at this temple were translated in the 1800s.

Photos of the solar eclipse that occurred on October 14. The first is from Don McCrady:

Thought I’d send you a hot-off-the-press shot of this year’s annular solar eclipse, this one from Winnemucca, Nevada.An annular solar eclipse is a total eclipse of the sun by the moon, where the moon is far enough away from the earth that its disk does not fully cover the sun’s, creating a “ring of fire” effect such as this one.  I took this with a Canon EOS R5 with an RF 100-500 x1.4 extender, for a total focal length of 700mm.

From Avis James:

Bill and I went to a field half way between Ruidoso and Roswell New Mexico in the path of the annular eclipse this morning.  We took a colander- it is has the Star of David pattern:
Here is the shadow it made at full angularity!  The dot in the middle of each circle is the moon in the middle of the sun!

From John Runnels, “Unknown mushroom species, Baton Rouge, Louisiana.” (Readers: can you ID?)

Finally, a weird giraffe from Bob Wooley of Asheville, NC:

I know you don’t usually do zoo photos, but if you feel like making an exception for an exceptional animal, you’re welcome to use these. You featured a story about this amazing unspotted baby giraffe the other day. I live about 90 minutes from Brights Zoo in eastern Tennessee, where she was born, so today I went there to see her for myself. It’s very difficult to get good pictures of her because her enclosure has a tight-mesh fence that you have to shoot through (unless you have a 12-foot-long photo stick). That’s why most of the news stories just use pictures and videos given to them by the zoo. But I got several that I think are worth sharing, and hold up to on-screen embiggening. She’s a seriously beautiful creature.
