If I was part of a protoplanet that was catastrophically destroyed in the early solar system, I'd be angrite too.

16 Psyche, an asteroid valued at $10,000 quadrillion for its rich metallic composition, is believed to be the exposed core of an ancient protoplanet. Conveniently positioned near the route to a future Mars colony, it could become a game-changing resource for space exploration and industry.

Check out our new paper on the first system where we can measure the C/O ratio in both a protoplanet and its disk!
I am excited to share my third paper of this year, and my first exoplanet paper with @thejason.wang, accepted to ApJL. We detected CO and water in the atmosphere of PDS 70 b, a protoplanet around its natal disk using Keck/KPIC. PDS 70 b shows a stellar-like C/O ratio (!). arxiv.org/abs/2411.15117
PDS 70b Shows Stellar-like Carbon-to-Oxygen Ratio
The $\sim$5 Myr PDS 70 is the only known system with protoplanets residing in the cavity of the circumstellar disk from which they formed, ideal for studying exoplanet formation and evolution within i...

3I/Atlas's nickel suggests it’s a fragment of a differentiated body. Warming, CO vents over nickel grains at the temperatures and pressures to form nickel carbonyl—basically the Mond process in space. Not alien tech, just natural metallurgy from a shattered protoplanet.
