The Habitability of Earth Tells Us the Likelihood of Finding Life Elsewhere

The habitability of Earth tells us the likelihood of finding life elsewhere

The hunt for habitable worlds has become a hot topic in astronomy. For decades, the search has been focused on planets in the "Goldilocks zone"; that narrow band around a star where water stays liquid, not too hot to boil away, not too cold to freeze solid.

The Habitability of Earth Tells Us the Likelihood of Finding Life Elsewhere

In a universe of a billion galaxies, Earth is the world known to have life. If we're a common example of what happens in the Universe, then our location can tell us something about habitability. A new study is about to flip everything we thought we knew about habitability on its head, examining the potential for life in exotic environments, such as rogue planets, water worlds, and tidally locked planets, and calculate how habitable they would be…

James Webb Telescope Discovers a Planet Even More Suitable for Life than Earth!

Future Space Imagine a planet that's even more suitable for life than Earth. Sounds impossible? The James Webb Space Telescope has just discovered exactly that. What makes this planet so special? Could it really support life — maybe even better than our own world? And the big question: is something or someone already living there?Future Space Imagine a planet that's even more suitable for life than Earth. Sounds impossible? The James Webb Space …

Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1

Last year, three Earth-sized planets were discovered to be orbiting the nearby Jupiter-sized star TRAPPIST-1; now, follow-up photometric observations from the ground and from space show that there are at least seven Earth-sized planets in this star system, and that they might be the right temperature to harbour liquid water on their surfaces. Michaël Gillon et al. report the results of a photometric monitoring campaign of the star TRAPPIST-1 fro…

Multiple Habitable Phases On Outer Exosolar Worlds - Astrobiology

As stars evolve to higher luminosities during first ascension of the giant branch, previously frozen terrestrial worlds may thaw and host liquid water on their surfaces. Eventually these outer worlds again become uninhabitable due to receiving too much incident light and their water inventory evaporating. Solar-mass stars experience a sudden decrease in luminosity entering the […] The post Multiple Habitable Phases On Outer Exosolar Worlds appea…
