News From the Search for Extraterrestrial Life 9

NASA is readying a set of eight instruments for the Ocean Worlds Life Surveyor to search for life on Jupiter’s moon Europa and Saturn’s moon Enceladus

In our universe The universe (as much of we know of it) has now been mapped: With 56,000 galaxies, there wold be, in principle, many places to look for life: “Galaxies, such as the Milky Way, are the building blocks of the universe, each comprised of up to several hundred billion stars.” – Phys.org A big barrier to exploration is, of course, the speed of light; most galaxies are many light years away and nothing moves faster than light. Incidentally, a group of astronomers recently claimed to have detected matter exceeding the speed of light. We asked theoretical physicist Rob Sheldon about that and he replied, “No, it isn’t going faster than the speed of light. Most superluminal objects are Read More ›

Could “Rogue Planets” Hold the Key to Extraterrestrial Life?

A new paper asks us to think about the possibilities of planets that have been kicked out of a predictable orbit.

A new paper asks us to think about the possibilities of planets that have been kicked out of a predictable orbit: In a new paper, Alberto Fairén from the Center of Astrobiology in Madrid, Spain, and I look into the possibility that planets wandering through interstellar space could also host life. These “rogue” planets may have been ejected out of their original solar system during the early, chaotic phase of planetary formation. There are two general types of rogue planets: gas giants like Saturn and Neptune, and rocky Earthlike planets. While the chances for life on gas giants is extremely remote, rocky migrating planets could in principle host microbial life. To do that, they would need internal heat from the Read More ›
