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 […]

Eclipse today

I asked reader Rick, who a while back had sent me links to eclipse viewing, to remind me yesterday so I could post them today. So, if you want to watch it either live or livestreamed, here’s where to go (links are all from Rick): NASA has coverage: https://eclipse2017.nasa.gov/eclipse-live-stream Space.com has a page of info […]

Eclipse coming: get your glasses now

I’m sure, if you’re in the U.S., you’ll know all about the eclipse next Monday, which reaches totality between 10:30 am and 3;30 pm, depending on where you are. If you want to see what the eclipse will look like from where you are (enter your ZIP code), go to this site. This is what […]

Readers’ wildlife photos

Reader Don McCrady sent some astronomy pictures; his notes are indented: I’ve been collecting some astrophotos this summer, and even an astro-video.  To start with, here’s a couple of recent images taken with my astro-rig. This is the Iris Nebula, part of a vast complex of dust in the constellation of Cepheus.  The central portion […]

Science-crazy lads build a model of the solar system in the desert

This lovely seven-minute video was called to my notice by reader Peter, and I don’t think I’ve posted it before. It shows a group of ambitious lads making a scale model of the solar system in the desert. The YouTube notes claim that this is “the first scale model of the solar system with complete […]

Readers’ wildlife photos

Don’t forget to send in your good wildlife photos; there’s always a need for more! Reader Don McCrady sent a terrific series of eagle-in-action pictures, and topped it off with a star photo. His notes are indented: I purchased a new Canon 6D camera a little while ago so I stuck my 400mm lens on […]

Readers’ wildlife photos

We have birds and stars today (don’t forget to send your pictures in!). The first batch comes from reader Darrell Ernst of Vero Beach, Florida. As always, photographers’ notes are indented: Thought I’d send you some pictures for your consideration for the Reader’s Wildlife Pics. They are a mix of bird images all taken within […]

Readers’ wildlife photos

Today we have a potpourri of photos; the first comes from reader Tim Anderson in Australia, who does astronomical photos: This is a picture of the Jewel Box (NGC 4755), a “small” open star cluster located very close to the Southern Cross. It contains about one hundred stars. The Jewel Box was first described by […]

Readers’ wildlife photos

Reader Tim Anderson from Oz sends astronomy, landscape and animal photos; his captions are indented. Here a two astronomical images I have made recently. First is a globular cluster, Omega Centauri (NGC 5139). This is easily visible to the naked eye, as it is the brightest such object in the sky and contains about five […]

Pan: a small “ravioli moon” of Saturn

On September 15, the Cassini spacecraft, 13 years after launch and after helping scientists acquire tons of knowledge, will cease its orbiting of Saturn and plunge into the planet’s atmosphere, disintegrating in the process. This suicidal move was deliberate, as scientists didn’t want to contaminate any of Saturn’s moons in case they prove habitable.  Just four […]
