The Cool Science Stuff Thread

And when it gets here in 2023 and we realize that it brought along a space-borne virus that is activated by our warm atmosphere....

Likely, silicon-based life that really enjoys munching on carbon-based beings.

Or it comes back with two ounces of gold and the space mining race is ON.
 
Just out of a webinar. The presenter said that bacteria spores that were 100M years old were reported to be regenerated recently.

Interesting and a little frightening.

This comes up now and again, also with arctic permafrost melting. But the reality is the bacteria/viruses/spores we suffer from today are the results of 100M+years of evolution, and as such are likely much more effective at getting us sick than something from the distant past. A 100M old bacteria would at best be optimized for flora and fauna from 100M years ago, not what we have now. Not to say it doesn't make a compelling plotline.
 
NASA’s SOFIA Discovers Water on Sunlit Surface of Moon

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

SOFIA has detected water molecules (H2O) in Clavius Crater, one of the largest craters visible from Earth, located in the Moon’s southern hemisphere. Previous observations of the Moon’s surface detected some form of hydrogen, but were unable to distinguish between water and its close chemical relative, hydroxyl (OH). Data from this location reveal water in concentrations of 100 to 412 parts per million – roughly equivalent to a 12-ounce bottle of water – trapped in a cubic meter of soil spread across the lunar surface. The results are published in the latest issue of Nature Astronomy.
