Readers’ wildlife photos

Today we have photos from several contributors. First, four photos from Patrick May (all readers’ notes and IDs are indented). In case your tank is running dry, here are two recent subjects.  A late season white-tailed deer fawn (Odocoileus virginianus) waiting for its mother to return and a PCC(e) combo of wildlife and food (sorry, no […]

The big announcement about supposedly biogenic chemicals on Venus: 11 a.m. Eastern time, 4 pm BST (watch here)

I’ve written a few times since yesterday about the Big Astronomy Reveal today. It’s going to be the subject of a live announcement from the Royal Astronomical Society in about an hour from this posting: at 11 a.m. Eastern time (US) and 4 p.m. BST. As I suspected, It’s going to report the discovery of […]

Big astronomy announcement coming up

Something big is brewing in the world of astronomy, and will be published soon, but it’s heavily embargoed, and so every time it’s mentioned it gets taken down, like the video in the second tweet below. One possibility is that they’ve discovered “signs of life” on Venus, in the form of phosphine in the atomosphere, […]

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 […]
