😮 Awesome views from Day 2 of #Artemis II this morning. @exploration.esa.int @esaearth.esa.int

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

right now the astronauts are calling houston because the computer on the spaceship is running two instances of microsoft outlook and they can't figure out why. nasa is about to remote into the computer

LIFTOFF!!! #NASA #Space #Artemis

I'm so excited! #NASA #Space #Science Can't wait to have us go back to the Moon. www.youtube.com/live/m3kR2KK...

I showed this graph in class yesterday on how measles cases in the United States plummeted dramatically after the vaccine was licensed in 1963. It’s not subtle and I could not resist observing: “This stunning design in measles cases was not thanks to vitamin A. It was not due to beef tallow.”

It's finally happening!

My god. Have you ever seen close-ups of sea star skin? 🧪🌊🌿

#GardnerDozois 's best short SF of the year collections are always good, but the 1998 one might be the best I've read. My favourite story was a re-read of Ted Chiang's Story of Your Life (later adapted as Arrival) and there are also extremely memorable […] [Original post on fediscience.org]

Heng Yang, a M.S. student in Mechanical Engineering and Applied Mechanics at #UPenn came to #Atlanta to visit #GeorgiaTech and his old physics instructor, yours truly, from when we were both at the #UniversityOfArizona. We got coffee, checked out the campus, and visited #Einstein.

I'm a simple man, I see #Science article about neanderthals, I click it. Actually, this is a neat article about mating preferences reveals through #Genetics and #Archeology to acount for the amounts of shared #DNA within X and Y chromosomes.

I was really looking forward to the March launch, totally understand if it needs to be pushed back for safety. #Science #NASA #Space #Artemis

NASA quietly updated its potential launch windows for its delayed moon mission, apparently now targeting March 6-11

The Pleiades star cluster (M45) captured over 25 hours. The blue glow is starlight reflecting off interstellar dust. The surrounding brown structures are the Integrated Flux Nebula, incredibly faint clouds lit by the glow of our entire galaxy. #astrophotography #astronomy #space #m45

This is globular cluster NGC 2419, also known as the Intergalactic Wanderer, found in the constellation Lynx, where globular clusters wouldn't normally be found. It orbits the Milky Way every every three billion years and its orbit takes it further than the Magellanic Clouds. #seestar #astronomy

January 7th is National Old Rock Day! Well here is an old rock! These white circles are cross sections of Archaeocyathids. These were a type of sponge that built reefs during the Early Cambrian. This comes from the the Forteau Formation in southern Labrador, Canada. Over 516 million years old!

The rate of global mean sea level rise has increased from ~2.1 mm/year in 1993 to ~4.5 mm/year in 2023. www.nature.com/articles/s43...

Stuff like this makes me so sad... Libraries are magical places. #Science #Space #NASA

There's a famous Feynman interview where he explains why ice is slippery. It turns out there's more to the story involving shear-stress and slippage of disordered ice layers. Things we experience every day still generate novel thought and research. #Science #Physics journals.aps.org/prl/abstract...

Hey Martians, did I mention we now also have a video of epic Phobos passing over a Martian dust storm near Pavonis Mons? 🌪️🌋🥔 Video & full info: flic.kr/p/2rNN8wk Credit: ESA/DLR/FUBerlin/AndreaLuck CC BY @esa.int Mars Express HRSC 300 MP Photo quoted below Easy zoom: easyzoom.com/image/674026

"Faculty would prefer more emphasis on teaching and somewhat more on service than they observed in practice. The largest disconnects were the overvaluation of publication numbers and grants and undervaluation of publication quality in research" #Science #AcademicSky #EduSky doi.org/10.1007/s442...

✨This NASA/ESA/CSA #Webb Space Telescope image shows the Westerlund 1 cluster, a group of massive stars located in our galaxy which are nearly as bright as a million Suns each. 🌌🎄🧪🔭 🔗 esa.int/ESA_Multimedia/Images/2024/10/The_exotic_stellar_population_of_Westerlund_1

What's next? We'll be allowing young earth creationism in astronomy 101? #Science #AcademicSky #EduSky

A fairwell to #3I/ATLAS, the interstellar visitor, as now it is moving away both from the Sun and Earth. It has dimmed to about mag 12 and has a tail pointing towards the Sun. It will continue getting dimmer and won't be visible in just a few months. #cometWatch #astrophotography

No raptors this morning but I did find this handsome specimen 🪶 (ID in alt-text)

When Star Trek the Movie came out back in '79 it had a much criticized sequence of shots where the camera basically drools over the Enterprise (1701A) in dry dock. But I was the target audience. I hope we get a Bird of Prey next. We probably also have enough […] [Original post on mathstodon.xyz]

We got to the final listed track, track 15 "The Fate of Thomas Light" and it's the saddest bit of music I've listened to in awhile. Everybody in the Bandcamp livestream was devastated. This can't be the end of Act III. #Protomen #Music #RockOpera

We're almost to the end of Act III. It's been a wonderful journey. #Music #RockOpera #Protomen

Comet 240P/NEAT has now a small fragment (B) that is bright enough to be seen with modest telescopes. The nucleus shines at about mag 12 while B is two magnitudes fainter. #cometWatch #astrophotography
