Finding independently evolved microbial life on Mars would be one of history’s greatest discoveries—but Robin Hanson’s Great Filter argument gives it a darker edge. If simple life arises easily, then whatever keeps the universe silent must lie later on the road from microbes to spacefaring civilisation—and it may still be ahead of us.
5+ day, 11+ hour ago (988+ words) A second origin of life could reshape the Great Filter argument. It would not establish that a catastrophe lies ahead: later evolutionary barriers and limits to our searches remain part of the question. By Life Signs · Edited by Lachlan Brown…...

Scientists find a huge 10-sided wave pattern swirling in the clouds over Saturn's south pole
1+ week, 3+ day ago (383+ words) The spinning, meandering decagon appears to be even bigger and more unstable than the hexagon of clouds around Saturn’s north pole that was spied by NASA’s twin Voyagers in the 1980s, the Spanish-led team reported Wednesday. This new jet stream formation…...
NASA grew corn in space but something "strange" happened???Here's what scientists found
1+ week, 5+ day ago (369+ words) What happens when a corn seed grows without Earth’s gravity telling it which way is down? NASA found the answer through experiments that sent dry corn kernels aboard space shuttles in the early 1990s. The seeds germinated in orbit and plants…...
