Research from NASA's Curiosity rover has found evidence of a carbon cycle on ancient Mars.

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

Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.

An international team of scientists and crew on board Schmidt Ocean Institute's research vessel Falkor (too) was the first to film the colossal squid (Mesonychoteuthis hamiltoni) in its natural environment. The 30-centimeter juvenile squid (nearly .. ...

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 a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a stellar pair.

A recently created RoboBee is now outfitted with its most reliable landing gear to date, inspired by one of nature's most graceful landers: the crane fly. The team has given their flying robot a set of long, jointed legs that help ease its transition ...

A study suggests that Homo sapiens may have benefited from the use of ochre and tailored clothing during a period of increased UV light 41,000 years ago, during the Laschamps excursion.

A new study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface -- findings that bring scientists one step closer to answering the profound question: Did ...

Researchers have isolated a giant virus, which was named Jyvaskylavirus. The discovery shows that giant viruses are more common in northern regions than researchers have thought. It also illustrates that there are still many structures whose origins ...
