K2-18b, an exoplanet 120 light-years away, may be the best hope to confirm that life exists beyond Earth. Here's what to know ...

Scientists have found possible signs of life on a distant planet in the form of gases that they say are normally linked to ...

The researchers found strong evidence of a chemical called dimethyl sulfide (DMS) in the planet's atmosphere. On Earth, DMS is produced only by living organisms, so it appears to be a compelling sign ...

Because DMS is almost exclusively produced by life forms like marine algae on Earth, astronomers consider it a potential "biosignature" in the search for life — past or present — elsewhere in ...

In the frigid waters originally hidden below, scientists discovered what appear to be new species of crustaceans, fish and other life forms. How is this possible and just how many more new life ...

But the biggest barrier to life on Mars is the lack of a strong magnetic field, which protects against the constant bombardment of ionizing radiation from cosmic rays and solar flares, which can ...

Scientists discovered complex life may have started 1.5 billion years earlier than previously thought thanks to phosphorus.

Scientists from the Centre National De La Recherche Scientifique in France and from Hawai’i have discovered that it is ...

The team’s discovery suggests that complex organic compounds can be synthesized in space even when no life forms have yet evolved on any planet. By analyzing spectra of star dust formed in ...

“There is no reason to believe that an alien life form would have to be using the same molecules we do,” Tikhonov said. In fact, some researchers believe life in other parts of the universe ...

As the atmosphere thinned, the carbon dioxide transformed into rock form. NASA says future missions ... whether Mars was ever capable of supporting life, and the latest paper brings them closer ...
