A sample obtained by NASA’s Perseverance rover of reddish rock formed billions of years ago from sediment on the bottom of a lake contains potential signs of ancient microbial life on Mars, according to scientists, though the minerals spotted in the sample also can form through nonbiological processes.
The discovery by the six-wheeled rover in Jezero Crater represents one of the best pieces of evidence to date about the possibility that Earth’s planetary neighbor once harbored life.
I honestly think this exact headline has shown up every month for the last five years now
I think you might be right. And I still get excited everytime anyway.
I’ve just read through the press release. It’s tentative (as all good science tends to be), but looks a lot more reliable than previous announcements.
Basically they’ve investigated, and can’t figure out any mechanism that could create this result, without life being involved.
On earth, we would call this obvious signs of microbe activity.
