There’s Life Inside Earth’s Crust | NOEMA
Revelations about microbes living deep inside Earth’s crust are challenging scientists’ conceptions of life and how it evolves.

Simply put, this is bad science, worse science communication, and deeply misleading to the public.
I know we all want to find alien life, but this is not it.
Should we observe K2-18b more to be sure? Absolutely. Only better data (and independent analyses) will reveal K2-18b's secrets.

K2-18b is back in the news, now with a bold claim that biosignature molecules (DMS and/or DMDS) have been 'detected at 3σ'.
Most exoplanet astronomers are extremely sceptical about these claims, let's see why (1/n).

Shocking Spherules!
Last week the Perseverance Science Team were astonished by a strange rock comprised of hundreds of millimeter-sized spheres… and the team are now working hard to understand their origin.

Parker space probe safe! 👍

Parker got more than seven times closer to the sun than previous spacecraft, traveling at a maximum speed of about 430,000 mph. It's the fastest spacecraft ever built

Census of Deep Life is the largest compendium of subsurface microbiological samples sequenced together to-date. We found some pretty cool microbial trends across major provinces of Earth's subsurface. Nice job pulling this together, @emilruff.bsky.social www.science.org/doi/epdf/10....

A new analysis of data from the Juno spacecraft suggests that the ice shell covering the ocean on Jupiter's moon Europa might be WAY thicker than anticipated. (With comments from @theplanetaryguy.bsky.social)
Possibly bad news for any hope of life signs from Europa Clipper, currently en route. 🧪🔭

Did you know we're sending a probe all the way to the Venus surface to figure out if the planet was ever Earthlike?

Research Suggests That Venus Never Had Liquid Water On Its Surface - Astrobiology
A team has found that Venus has never been habitable, despite decades of speculation that Venus was once much more like Earth than it is today.
