Please look up the influenza epidemic of 1918-19 to understand that the CDC not selecting strains for next year’s vaccines sets the stage for a public health calamity that will, without doubt and at bare minimum, catastrophically and directly impact people you know. This is a five alarm fire.

Because of four decades of bad faith narratives by rich folks who want your taxes to go up and their taxes to go down, most folks don’t know this: career federal workers are heroes who work extremely hard every day and go above and beyond all across America to improve your lives.

The people who voted for Trump because they thought he’d pull the U.S. back from foreign entanglements and overseas adventurism are really among the prime suckers of our era.

If they "are serious about slashing NSF, the result would be catastrophic, the same program manager warned. Cutting the $10 billion grantmaking agency in half would “gut the intellectual center of U.S. leadership in science and technology,” the official said. www.eenews.net/articles/sci...

"pip install sk8plotlib" if you want to give it a try! Note that rescaling the skateboard to the data in the plot isn't supported yet, & the skateboard always spawns at (0,0) still, so if you have large or small numbers (or a log plot) then it won't like it Instructions on GitHub:

Solstice imaging with Celestron Origin - these all came from 2 ~hour-long exposures. Stay up late this time of year, you can see into the Realm of the Nebulae (plus an occasional photobombing actual nebula). M108/M97/M96/M105 and friends.
Edge-on spiral galaxy NGC 3556 AKA M108, showing bright star-forming knots and a winding lane of dust absorption.Owl Nebula (M97), nearly round greenish-blue cloud with blue central star and two darker patches line an hourglass (the owl's eyes, I think).Disturbed spiral galaxy NGC 3368 (M96), with complex dust tendrils, ringlike outer spiral arms, and edge-on red background galaxy behindone of those outer wrms.Galaxy triple NGC 3379 (M105),lenticular galaxy NGC 3384, spiral galaxy NGC 3389 in Leo. NGC 3379 is a photometric standard galaxy and extraordinarily round from our point of view (despite Doppler observations showing that it has net rotation along our line of sight. Go figure).

Recently talked to a student who admitted to using ChatGPT as a study device - by feeding it all of the class lecture slides and having it generate summaries. So now OpenAI has ownership of all the slides my co-instructor and I created from scratch…

Well, this is neat! People are already using my step-by-step guide on processing JWST images and producing results after I published the article yesterday. And look, they are following the way I outlined to pay proper credits to the science team 🥹🥹 (still need to stress the usage of alt-text pls!)

 Spent pretty much the whole afternoon playing with JWST images.  Managed to import different colour channels, learnt tons!  That article was great! Thanks!  Cant believe this data is just there for anyone to do what they want!Tweet with text: Forgot to credit:

Since so many have asked, here’s my hot take on the spherules Loeb found and the manuscript he’s loudly rushed to the world. These are pretty typical cosmic spherules. Had he done the *obvious*--a control sample 100 km away from the meteor--he’d have found the same thing. 1/20

Today, we have new views of the Whirlpool Galaxy from the JWST! I laid the images taken by each instrument side by side, plus the composite, and the Hubble version. You can really see how the mid IR (MIRI) brings a whole new light to galaxies! Which version is your favorite?
