New orbital data reveal that the most recently active volcanic systems on Mars weren’t simple one-off blasts into space.

That does not mean that the detected alkanes are evidence of life on Mars; the conclusion relies on modeling how radiation ...

The discovery that amino acids can form in more ways than we thought is another boost to the search for life beyond Earth. If ...

What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, ...

A new paper suggests that BARSOOM may have been alive on the planet, and was killed in the Viking experiments.

Scientists combined lab radiation experiments, mathematical modeling and Curiosity data to ‘rewind the clock’ about 80 million years — the length of time the rock would have ...

Dubbed HD 137010 b, the planet might fall just within the outer edges of its star's 'habitable zone', meaning there could be liquid water on its surface and a suitable atmosphere for life.

A scientist at the University of Glasgow has delved into the possible existence of massive hypothetical energy-harvesting structures called Dyson spheres. In a new study, they showed that both stellar ...

A scientist argued that a Viking lander experiment in 1976 detected microbial life on Mars and urged NASA to repeat the tests before future missions. We asked retired astronauts about their favorite ...

NASA’s Curiosity rover has discovered the largest organic molecules ever detected on Mars. Found inside a 3.7-billion-year-old rock from a dried-up lakebed, these long-chain carbon molecules raise new ...

New theoretical models have strengthened the case that immense, energy-harvesting structures orbiting their host stars could exist in principle in distant stellar systems. With the right engineering ...

Science fiction has always been a genre that, whether intentionally or not, has been able to somewhat predict the future. Be it through advanced technology, the use of media, or general political ...
