TRAPPIST-1, designated as 2MASS J23062928-0502285, is an ultra-cool red dwarf star that is slightly larger, but much more massive, than the planet Jupiter; it is located 39.6 light-years from the Sun.

We discuss the MARSIS experiment, that is able to use Ground Penetrating Radar to detect changes in minerals, ice, or liquids underground. We also discuss what NASA thinks about this discovery, and whether or not life could exist in this lake. Thanks for watching! And consider subscribing if you enjoyed this video!

A study published July 23 in the journal Astrobiology said there was a time when the moon had the right conditions to support life.

The Moon doesn’t appear to have what it takes to support life now, but researchers suggest that wasn’t always the case.

According to a report by Geek.com, a new study suggests that Saturn’s largest moon, Titan, may have the potential to produce life as we know it. A team of researchers using data from the Cassini spacecraft examined the icy moon looking for biological molecules. Leader of the study Catherine Neish, found that when exposed to liquid water, organic molecules like the ones on Titan are capable of producing a range of biomolecules, including amino acids. Neish and her team reportedly focused their attention on craters, particularly Sinlap, Selk, and Menrva. The team wrote, “We determine that the best sites to identify biological molecules are deposits of impact melt on the floors of large, fresh impact craters." https://www.geek.com/news/psst-alien-hunters-check-inside-craters-on-saturns-moon-titan-1746989/?source http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Recently NASA announced that the Curiosity rover discovered organic molecules in an ancient mudstone on Mars. In this video, we discuss the importance of this discovery, how the Curiosity rover was able to determine that it was organic molecules, and what these discoveries mean for future missions to the Red Planet.

The ExoMars Rover is expected to land on the Mars in two years. The ExoMars Rover contains a miniature chemistry lab. NASA is going to use the miniature chemistry lab to search for sign of life on Mars. The Mars Organic Molecule Analyzer will analyze organic molecules like amino acids. NASA employees and space fans are extremely excited to find out if there's life on Mars. https://www.digitaltrends.com/cool-tech/exomars-rover-mars-organic-molecule-analyzer/ http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com
