A grand cosmological event: the collision of two neutron stars pumps up the physics community

Well, this astronomy/physics news is just in, and of course it’s above my pay grade, but at least I can refer you to articles in both the New York Times and CNN about a new discovery: the collision of two neutron stars, emitting both electromagnetic and gravity waves. The collision was detected in August, but […]

Cassini reveals Saturn’s kittens

by Matthew Cobb The Cassini probe may have plummeted into Saturn’s gassy depths, becoming part of the planet it had observed so long, but it still keeps giving science. As Rae Paoletta noted on Inverse a couple of days ago, Cassini’s data reveal the presence of kittens in the F ring of Saturn. Sadly these […]

Readers’ wildlife photos

Today is Potpourri Day, assembling the photos from readers who sent only one or two. The first is by reader Tim Anderson from Oz (all readers’ notes indented): This is a picture of the Tarantula Nebula in the Large Magellanic Cloud (the nebula is identified as NGC2070). The picture comprises sixty images each of red, […]

Readers’ wildlife photos

We have a variety of photos today, with readers’ notes indented. The first is from Michael Glenister: I took my kids to Ottawa last month, and when we visited the Mackenzie King estate we spotted some Ebony Jewelwing damselflies (Calopteryx maculata) by a creek.  Until we got close enough, we weren’t sure whether they were an […]

Readers’ wildlife photographs

Today we begin with some photos by Stephan Barnard, who’s been absent from this page for a while. His notes are indented: The first is of a Rufous Hummingbird (Selasphorus rufus), not unlike some others I’ve sent. The second is a Solitary Sandpiper (Tringa solitaria), a photo that would otherwise be unremarkable except that it’s […]

Readers’ wildlife photos

Today we’re also including astronomy (as we sometimes do): some nice eclipse pictures and one of Saturn. And we’ll have a token animal. First, some lovely eclipse photos taken by reader Don: I’m late to the party submitting these, but I haven’t had a lot of time to process them. The first shows the eclipse […]

Readers’ eclipse photos

If I’d thought of it, I would have asked readers to send in photos that they took of the solar eclipse. But several did anyway, and here they are. These are from Michael Glenister: I drove from Vancouver down to Jefferson, Oregon to see the eclipse.  Even heading down the day before traffic was bad […]

The eclipse from Wisconsin (and Texas and Canada)

by Greg Mayer In Kenosha, Wisconsin, the eclipse yesterday was at about the same time as in Chicago, 11:54 AM to 2:40 PM, with the peak at 1:18 PM, and slightly less complete (85%). The eclipse glasses worked fine, but drifting cloud cover obscured the view for much of the time. And, without specialized cameras, […]

A question from PCC(E)

I’m admitting my ignorance by asking this, but if I don’t ask I won’t learn. Here is my question: “Why, when there’s a solar eclipse, is the Moon exactly big enough to blot out the Sun? Does this have something to do with the laws of physics as manifested in orbits, or is it just […]

Not a joke: Atlantic article notes that eclipse path moves over many white areas, uses path of totality to indict America for racism

UPDATE: There are now over 500 comments on Ristroph’s piece, virtually all of them critical, and some quite funny. I actually feel sorry for the poor woman, but maybe she doesn’t read comments. Here are a few I selected quickly. _____________________ The present ideological climate in America is such that almost anything can serve as […]
