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…

Why Some Experts Hope We DON’T Find Life on Mars

Many thinkers worry about what will happen if the extraterrestrials land. But will they feel worse if we never find ET?

Recently, prominent theoretical physicist Michio Kaku (pictured) told media that reaching out to extraterrestrials is a “terrible idea.” Kaku, author of The God Equation: The Quest for a Theory of Everything (2021). So long SETI, after all these years? Well, not quite. He explains, Soon we’ll have the Webb telescope up in orbit and we’ll have thousands of planets to look at, and that’s why I think the chances are quite high that we may make contact with an alien civilisation. There are some colleagues of mine that believe we should reach out to them. I think that’s a terrible idea. We all know what happened to Montezuma when he met Cortés in Mexico so many hundreds of years ago.…
