"It would be fair to say that we have seen the light for finding habitable planets," the study's co-authors say.
Life on a rogue Super-Earth would be difficult, but organisms have been shown to thrive even in very extreme conditions on regular Earth.
An ultra-rare rock from Mars upended the traditional view of how rocky planets receive essential ingredients for life.
Abigail Fraeman, deputy project scientist for the Curiosity rover, shares stories from Mars in a new episode of Motherboard’s Space Show.
A new class of ‘Hycean’ planets may have just expanded the definition of habitability.
A radioactive isotope profoundly affected the origin and evolution of our solar system. Now, scientists have spotted it in a system of budding stars.
“The night-time ice glow occurring on Europa may be very unique and unlike any other phenomenon in our Solar System,” according to a new study.
Worlds orbiting small red dwarf stars might be less vulnerable to damaging space weather, which could boost the odds that they host life.
"We are so focused on finding a mirror image of Earth that we may overlook a planet that is even more well suited for life,” said the lead author of a new study.
The new research lends credence to the idea of briny lakes existing under the Martian surface and is an important development in the search for Martian life, if it exists.
The detection of phosphine is “not robust evidence for life” on Venus, scientists say, but a biological origin for the signature has not been ruled out yet.
“It looks like the majority of these organisms are living at energy regimes that are below what we thought was even capable of maintenance—just staying alive.”
