A three-dimensional map of the Universe

Well, I can’t say I fully understand what’s being shown here, except that it depicts the detectable galaxies in the Universe (some not seen because the Milky Way hides them).  Cosmos has an explanation that I put below the video. If you’re an astronomy buff, you’ll probably understand this, and I’m hoping the cosmology mavens […]

Readers’ wildlife photos

On this site, astronomy counts as “wildlife”, and readers Leo Glenn and Mark Jones sent some lovely pictures of Comet Neowise, which I haven’t been able to see. Leo and Mark’s words are indented; click photos to enlarge them. First, photos from Leo: While these technically aren’t wildlife photos (well, one might qualify), I thought […]

Readers’ wildlife photos

Today we have some odds and ends, individual pictures (or a small set) sent by readers. First up is from Joe McClain (all readers’ captions are indented): I submit for your consideration for the Readers’ Wildlife Photos category this photograph. It depicts interspecies interaction between a young Sylvilagus floridanus [Eastern cottontail] and a stunning specimen of […]

Photos of readers

Again, the penultimate one in the queue (they come in at a rate of one per day). Please submit yours! The reader is David Harper, who says the following: This photograph was taken on the morning of 21 August 2017 at a ski chalet in central Idaho.  I was staying there with my wife, her […]

Readers’ wildlife photos

We have two contributors today. First, Art Williams sent some photos and videos, which include a fawn. Remember, if you see a fawn by itself, especially a very young one, leave it alone, as it’s almost certain that it was been left to shelter place while Mom went off foraging. Only call for help if it […]

Star “outburst”

I originally gave this timelapse series the title “star explosion,” but in fact it’s not clear what the deuce is going on here. What is clear is that it’s something spectacular.  The YouTube notes describe what we’re seeing and how the montage was made: The unusual variable star V838 Monocerotis (V838 Mon) continues to puzzle […]

Readers’ wildlife photos

Actually, we have two disparate topics today: owls and astronomy. Is there a connection? You tell me. The owls come from reader Gregoray, who lives in Austin, Texas. He has three young Eastern screech owls (Megascops asio) in his yard that fledged in the last week. His notes (sent on April 21): We have had […]

Readers’ wildlife photos

Today we have a mélange of photos from several contributors. Their own words are indented (and please send me good photos): First, from reader David Fuqua, something we need: the bluebird of happiness. Being housebound this spring has given me a chance to observe the Eastern Bluebirds (Sialia sialis) nesting. The mother and father are both […]

Readers’ wildlife photos

Bring out your photos! There’s always a need for more. Today we have two contributors from different continents. First, Liz Strahle from the U.S. shows us some bird photos (all captions by readers are indented): Attached are some wildlife photographs I took in the last month or so. These are all in New Jersey. I […]

Readers’ wildlife photos

Remember, landscapes and astronomical bodies count as “wildlife” here. Please send in your good photos. Today we have both birds and the cosmos. First, some birds from reader Garry VanGelderen, sent on March 5. All IDs and notes are indented. I’d call this “Five Ways of Looking At a Blue Jay”: Since about a week […]
