Back from a mission to the moon 🌕, astronauts from Artemis II visited UN Headquarters in New York.

They shared an important message for humanity about our shared purpose on Earth. 🌎

Watch and see what the #Artemis explorers had to say.

[NASA @NASA]

Start your week with some new photos from Artemis II!

Though our journey around the Moon has ended, we're still retrieving plenty of new images. Keep an eye on our Artemis II multimedia gallery for image highlights from the mission: https://t.co/XInWMJwMYY

I have not been on this account much. I came back to tell you that Harvey (no not the one many followers know!) is now worth $11 billion. I am told more than more than Spirit Airlines, Nordstrom, and Macy's combined https://t.co/BxbzjxAovN

Three AI companies raised over $30 billion in a single weekend.

Legal AI company Harvey is now worth $11 billion — more than Spirit Airlines, Nordstrom, and Macy's combined.

The dot-com boom was a bake sale compared to this.

That's an interstellar comet, imaged by a satellite orbiting Mars. You live in the future!

I realize did not quite achieve their goal, but congratulations to all involved in the launch. Great to see Canada active in space launch, and by a university student group particularly impressive. https://t.co/cmJ7HB0oCM

Great to see research by Mount Allison's Vett Lloyd featured on the Globe today! https://t.co/k5FCz98Y41

Infinite gratitude to the amazing sponsors and exhibitors powering #AstroRob 2025 and every edition before. You make it a first-class networking event every time — thank you for being a part of it! 🌌✨

What physics breakthrough do you think will happen in the next decade? ✍️

Physics. Mathematics. Reality. Universe.

Stephen Wolfram's "Theory of Everything" is free on line, as a 448-page PDF. Here is a sample figure, to intrigue you. Source: https://t.co/wYtI7zv4EH

This has never happened before. Every living former NASA Science Chief united to sign a joint letter to Congress, urging them to reject a devastating 47% cut to NASA’s science budget.

Led by our board member and former NASA Associate Administrator of Science John Grunsfeld, we helped bring this letter to life. Read the full letter here ⬇️ https://t.co/r2L1GOYXl2

A view of lightning that's nothing like what we see on the ground: crew observations and instruments on the @Space_Station can help us better understand the behaviors of storms.

ESA's astronomers are actively tracking 3I/ATLAS, which is now the third confirmed interstellar comet to pass through our Solar System!

ICYMI, this preprint from Western U group takes comprehensive look at interstellar meteoroid rate for mm size objects. https://t.co/YiV3Z4CGnB #meteoroid #hyperbolic #interstellar

[NASA JPL @NASAJPL]

There's a new interstellar comet in the neighborhood!

Known as 3I/ATLAS, this comet poses no threat to Earth – but it does provide a rare opportunity to study an object that originated outside of our solar system: https://t.co/7ihCiHi91t

@b612foundation has taken the orbit and uncertainty of asteroid 2024YR4, sampled 10K trajectories from the current uncertainty, and propagated them forward. 2.3% of those hit the Earth on Dec.22, 2032. Here is where they hit.

[Tony Dunn @tony873004]

Here are 70 clones of #asteroid 2024 YR4 that do hit Earth, highlighting the impact risk corridor. There are some big cities along that line: #Bogota, #Lagos, #Mumbai.

☄️ Excited to share our new paper in JGR: Planets @jgrplanets:

"Inferring Fireball Velocity Profiles and Characteristic Parameters of Meteoroids From Incomplete Data Sets"
