“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.”
The new discovery adds to a growing pile of evidence that Mars may have been more hospitable to life in the distant past.
“The next intriguing question would be whether life survived the star’s death or started all over again—a second genesis.”
"Oxygen is one of the most exciting molecules to detect because of its link with life, but we don't know if life is the only cause of oxygen in an atmosphere.”
CHEOPS, the first mission focused on measuring exoplanet sizes, blasted off on Wednesday morning from French Guiana.
K2-18b is the "best candidate" to host alien life outside the solar system.
Reddish deposits of ammonia on Pluto suggest that liquid water, the key to life as we know it, exists below its surface.
