From Space.com:
"Astronomers have spotted the exposed core of a massive alien world, an unprecedented find that could shed considerable light on planet formation, evolution and diversity.

The planetary core, called TOI-849b, is unlike anything scientists have seen before, and it could hide a wealth of exciting information in its bizarre depths, researchers say."

Hi Stephen. An interesting pair of links on TOI-849b. As suggested in the article, the outer gases could have been dissipated from it's atmosphere back into space long ago. And, it should be fascinating to see what the NASA mission to the solar system metallic asteroid Psyche finds in 2022. Thanks for these reports Stephen, and keep up the great astronomy news posts.
