Marie Curie's notebooks, which are radioactive and must be stored in a lead-lined box in the Bibliothèque Nationale. Curie’s corpse is also radioactive. Her coffin is lined in an inch of lead. Both will remain radioactive for 1,500+ years.

In 1925, Dr. Cecilia Payne completed her PhD thesis, described as “the most brilliant ever written in astronomy.” At a time when few entered academia, Payne discovered what the universe is made of. Her work began a revolution in astrophysics.

Dr. Payne-Gaposchkin became the 1st female professor & 1st female department chair at Harvard. Given most of us remember names like Darwin & Newton, we should also celebrate Payne.

I just moved to sciencemastodon. I'm a vertebrate palaeontologist and my research focusses on Mesozoic marine reptiles. The photo shows a perfectly preserved skull of the weird ichthyosaur Eurhinosaurus. The specimen is approx. 1 m long and was found in the Lower Jurassic Posidonia Shales of Holzmaden (Germany). It is on display at the Naturmuseum Winterthur (Switzerland).

Shark researchers watched 202 television episodes of , and they were not not not impressed.

Among the findings:
🦈 Most featured no actual scientific research
🦈 Many others featured questionable research and pseudo-science
🦈 Only 6 episodes had actionable tips for shark conservation
🦈 There were more white male non-scientists named Mike interviewed than women of any profession



This is especially for folks just discovering The Conversation on - but anyone curious about the world will find it interesting and informative reading.

We've collected 8 of our most popular articles of the year in links, and in a downloadable PDF.

Among them:
🦟 The science of mosquito magnets
🔭 The search for super-earths
🌋 Why we can't just throw all our trash into volcanoes to get rid of it

All written by experts.



Who is ready for ????

This week follow along as I walk you through how observes transiting* , what spectroscopic data looks like straight from the different instruments on the telescope, and why we have/use different instruments

(*there are other ways to observe exoplanets with JWST, but I'll only talk about planets that cross between us and their star in this thread)

Long 🧵 Warning!

A gif of JWST. The video starts from a low angle, looking at the bottom of the sunshield, which appears slightly pink/purple due to the material it's made of. The view rotates to above the sun shield and the gold hexagonal mirrors come into view. Eventually the view centers on the mirrors and we see a reflection of the secondary mirror which is what reflects light back to the telescope, and then slowly the image zooms in until all we see is gold and then the gif starts over.


One of my map of the universe makes it to the cover of The Astronomical Journal. It shows the evacuation of cosmic flows out of the Local Void, a giant cosmic void found in our immediate vicinity. Our galaxy the Milky Way is at the center and the map also features the Virgo galaxy cluster, located 50 million light-years away.

Space exploration back in 1946…
We have gone a loooooooong way.
First ever image from makes history | This Day in Space (24 Oct. 1946)
“The grainy, almost unidentifiable photo... was taken on October 24, 1946, at an altitude of 65 miles (105 km) above the New Mexico desert. It was captured on a 35-millimeter motion picture camera being hurdled into space on a U.S. captured German V-2 missile. The camera was enclosed in a steel case for protection as a few minutes later it returned through Earth’s atmosphere and slammed into the ground at about 500 feet per second.

The is officially hailed as the first image captured of Earth, while also being the first-ever image from space.”

It's such a simple thing but it's so very beautiful, when moons and other planetary bodies come together. And the camera team lead by @carolynporco for Cassini were absolute masters at catching these events.

Hey, I'm Rune and I'm a solo independent game developer. Main skills are in , and finding ways around doing art.

Stuff I'm Super Passionate About:

(On as many platforms as I can)

and (some of the best SciFi's made had science consultants, and some amazing science has come from being inspired by SciFi)

I have three cats that I adore sharing with the world. Nutmeg, Cinnamon and little Chilli who has epilepsy.


I bet you’ve heard of Galileo & Hubble, but what about Henrietta Swan Leavitt?

Leavitt changed astronomy. She figured out new ways to measure a star’s distance from Earth & her work helped determine the universe is expanding.

Her boss, Edward Pickering, published her findings UNDER HIS NAME. Later, Shapley used her findings to determine distances around the Milky Way w/o credit.

Leavitt’s work is still used today. So next time you hear about famous men in share her remarkable story.
