Now on @sciam.bsky.social: A rare meteorite recovered in 2019 from the Sahara Desert seems to be a half-kilo hunk blasted from the depths of a long-lost planet that roamed the (very) early solar system. Cool story by @jennaahart.bsky.social.

The Arrakihs mission has been adopted as ESA's next F-class mission, with an expected launch in 2030! It will look at the low surface brightness outskirts of 80 Milky Way-like galaxies.

Now on @sciam.bsky.social: Yikes! Lots of folks were holding their breath this morning due to a sudden situation on the ISS. Astronauts briefly took shelter in a docked spacecraft and prepped for potential evac due to worsening air leaks.

Now on @sciam.bsky.social: Heavy-duty machine learning and a surfing mathematician are at the forefront of a millennia-old quest (and a million-dollar prize) to understand how fluids swirl.

Now on @sciam.bsky.social: The most fecund sites for forming planets throughout the cosmos might be... the outskirts of supermassive black holes? What?! Nice piece from @philplait.bsky.social.

Hints of high-pressure chemistry within a rare meteorite suggest this fallen space rock comes from a planet gone wrong in the solar system’s early history
Thread on our new paper on arxiv today! We stumbled across a weird sinusoidal systematic that we think appears in every observation from the NIRISS instrument on JWST. We derive a correction and see how much it impacts exoplanet spectra. (1/N) #astro #exoplanets 🔭🧪

The European Space Agency’s (ESA) Science Programme Committee has adopted the Arrakihs mission. Planned for launch by the end of 2030, Arrakihs will capture the faint light from nearby galaxy haloes. ...

Now on @sciam.bsky.social: Astronomers may have just found a primordial black hole at the Milky Way’s edge that could help solve the mystery of dark matter.
They’ve named it “Phoebe.”
Nice piece by @astrojonny.bsky.social.

Now on @sciam.bsky.social: China’s Tianwen-2 spacecraft is prepping for a close encounter on July 4 with near-Earth asteroid and “quasi-moon” Kamo‘oalewa. Tianwen-2 will seek to grab samples from the small, enigmatic space rock for return to Earth in 2027.

NASA’s Artemis III crew includes three NASA astronauts and one European Space Agency astronaut
NASA ordered its astronauts to take refuge inside a docked SpaceX Crew Dragon spacecraft and prepare for potential evacuation of the International Space Station, but the crew returned to normal operat...
A blip of light in the outer reaches of the Milky Way might be a bizarre black hole born at the beginning of time itself—and the long-sought solution to the mystery of dark matter. Astronomers are cal...

The Tianwen-2 spacecraft is slowly closing in on the near-Earth asteroid Kamo‘oalewa, on a mission that would bring China’s first asteroid samples back to Earth in 2027
We quantify an unusual flux-dependent systematic which is periodic in raw counts in flight data from the James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph (JWST/NIRISS), used...
