Could life exist around red dwarf stars? That's one of the most important questions in our search for life in the universe. Red dwarf stars are the most common type of star and they live for up to several trillion years. So if life can exist around red dwarf stars, then life might be very common in the universe. In fact, the two closest planets to the Sun, Proxima Centauri and Barnard's star, each host potentially habitable planets (Proxima b and Barnard b). 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/28YZEmkTvew 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🐟 From out of town?

As astronomers find more and more planets around other stars, the big question we want to know is: are they habitable, could there be life there? The vast majority of stars in the Milky Way are red dwarf stars, and most of the planets in habitable zones have been found orbiting these cooler, less massive stars. What are the chances that life could get going on these worlds?

If life exists on Mars, it still hasn’t showed itself, but recent evidence from the red planet increasingly supports the possibility. Life could have developed there. Most of the conditions are right and nothing found so far rules out the possibility, either in the distant past or today. If something is or was alive there, it’s probably tiny. Since microbes make up the vast majority of life on Earth, microbes are the most likely thing to find somewhere else. It’s not so easy figuring out what “alive” means on another planet—let alone finding a living microbe. The upcoming Mars 2020 mission and its rover-based mobile laboratory will take another giant step toward answering the question. First, though, science needs to answer some questions about life here on Earth. It turns out that the dark, hard manganese oxide in varnish coating cliff faces and rocks throughout the American Southwest and elsewhere has a lot to say about the subject.

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
