Astronomy Cast Ep. 514: Planetary Protection Protocols

   13 hours ago   |  Universe Today

As we send rovers and landers to other worlds, we have to think about the tiny microbial astronauts we’re sending along with us. In fact, NASA is so concerned about infecting other worlds that it has established the planetary protection protocols. Just to be safe. We usually record Astronomy Cast every Friday at 3:00 pm …

Saturn’s moon Titan is a very strange place. It’s surrounded by a dense, opaque atmosphere, the only moon in the solar system with an atmosphere to speak of. It has lakes of liquid methane on its surface, maybe some cryovolcanoes, and some scientists speculate that it could support a form of life. Very weird life. …

Geothermal Heating Could Make Life Possible on the Super Earth Planet at Barnard?s Star

   20 Jan 01:00:01   |  Universe Today

In 2018, scientists announced the discovery of a extrasolar planet orbiting Barnard’s star, an M-type (red dwarf) that is just 6 light years away. Using the Radial Velocity method, the research team responsible for the discovery determined that this exoplanet (Barnard’s Star b) was at least 3.2 times as massive as Earth and experienced average …
