Astronomers have detected possible chemical signs of life on a faraway planet. But they caution much more work is needed to confirm their findings.

Astronomers have made a detection suggesting biosignatures, or signs of biological activity, on an exoplanet located 124 light-years away. But experts are skeptical.

A new discovery could represent the most concrete evidence of alien life to-date, but scientists caution that further studies are needed.

Dating of cosmogenic chlorine isotopes yields long-term estimates of fault activity in Italy, showing that periods of ...

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they ...

U.S. team of researchers detected signs of two chemicals in the planet's atmosphere long considered to be "biosignatures" indicating extraterrestrial life.

In a potential landmark discovery, scientists using the James Webb Space Telescope have obtained what they call the strongest ...

Astronomers have discovered a major sign of life — and “the first hints… of an alien world” on a distant planet orbiting ...

A new study suggests the universe may rotate -- just extremely slowly. The finding could help solve one of astronomy's biggest puzzles.

Astronomers have found thousands of exoplanets — worlds beyond our solar system. Most of them are in single-star systems, ...

The rotating model, which does not break any known law of physics, suggests the universe could spin around once every 500 billion years. This would be far too slowly to detect easily, but enough to ...

Further studies are needed to determine whether K2-18b, which orbits a star 120 light-years away, is inhabited, or even ...
