"Aliens Next Door?" — You can see me chatting to @chrislintott.bsky.social on the BBC's Sky at Night next Monday about some of our experiments @theukca.bsky.social to understand recent observations by Perseverance Rover on Mars. @severinhryn.bsky.social gets a shout-out! #astrobiology

🚨New preprint (not peer reviewed)! Last year, NASA announced "potential biosignatures" on Mars: bleached spots in rust-red rocks. Here, we show that rust-dissolving bacteria really can make spots like these. Next step: see if we can make them without bacteria! #astrobiology doi.org/10.64898/202...
