Cecilia Payne-Gaposchkin ✨ figured out what stars are made of ✨ when she was just 25. 🔭🧪

Her PhD thesis basically established the Harvard astro department — at a time when Harvard didn't officially allow woman students.

I wrote this little profile to mark the 100th anniversary of her thesis:

Duffy says today's announcement is consistent with "the president's vision and mission of continuing science to support human exploration beyond Earth."

Fact check: this administration has proposed canceling Mars sample return.

To sum up: we have

🪨 A cool rock from #Mars that may or may not hold evidence of ancient life

🛰️ An internal fight over whether NASA should spend its money on science or human exploration, and on what planet

🤔 A totally uncertain future for this amazing rock

There are many layers going on in this NASA press conference. Notably, the head of science Nicky Fox just gave a hard sell for NASA science missions, in the presence of the acting administrator who has not said a lot about science to-date.

If you like cool Mars rocks (and why do you follow me if you don't?) you're in luck there are a lot of them! 🔭🧪

Check out some of the weird rocks that have turned up on Mars

Some of the unusual rocks carry stories about water on Mars. One has hints of long-gone microbes. All tell of a dynamic, complex planet.

Earlier this week @meprillaman.bsky.social had a really fun story about a cool rock on Earth that can help scientists learn how to study the cool Mars rock - if they ever get their hands on it. The Mars Sample Return mission is on Trump admin's chopping block. 🔭🧪

A Mars rock analysis tool proved its mettle on a chance find from Arizona

On Mars, the Perseverance rover found a spotted rock that could bear signs of ancient life. On Earth, a researcher used a lookalike for a dry run.

There's a NASA presser happening now in which acting admin Duffy said "This very well could be the clearest sign of life that we’ve ever found on Mars." That doesn't mean it is a sign of life. We covered this cool rock in 2024, paper in Nature is out today: 🧪🔭

NASA's Perseverance finds its first possible hint of ancient Mars life

The NASA Mars rover examined a rock containing organic compounds and “leopard spots” that, on Earth, are associated with microbial life.

This story began with a JPL press release in July 2024, soon after the #Mars rock was discovered. www.jpl.nasa.gov/news/nasas-p...

Today is the publication of the peer-reviewed paper describing what's in it. That @nature.com paper is here www.nature.com/articles/s41...

NASA’s Perseverance Rover Scientists Find Intriguing Mars Rock

The six-wheeled geologist found a fascinating rock that has some indications it may have hosted microbial life billions of years ago, but further research is needed.

An important part of this story (which I am not expecting the NASA live stream to mention) is that the sample return mission that could potentially answer the question of life on Mars is being threatened by budget cuts from the Trump administration www.newscientist.com/article/2495...

NASA hasn't found life on Mars yet – but signs are promising

A rock found last year on the surface of Mars offered tantalising evidence that life once existed on the Red Planet. Now scientists have found yet more evidence that could point to the existence of an...

I looked forward to seeing @vrubinobs.bsky.social's telescope in action for years. But when I arrived in Chile for a visit this spring, the structure was lying motionless, aimed at the horizon. Here's how the crew solved a mystery and got the camera back up 🔭🧪

The first nuclear explosion, called the Trinity test, was set off 80 years ago today in New Mexico. Since then, more than 2,000 nuclear explosions have rattled the globe, and a renewed interested has stirred dismay among scientists.

Calls to restart nuclear weapons tests stir dismay and debate among scientists

Many scientists say “subcritical” experiments and computer simulations make nuclear weapons testing unnecessary.
