Mars was a very different place as a young planet. Liquid water dotted the Red Planet’s landscape with lakes and rivers. But the planet’s climate changed drastically in the past few billion years.

Researchers simulated Martian permafrost and ice cap conditions in a laboratory, exposing *Escherichia coli* samples in pure water ice and water-sediment mixtures to cosmic radiation equivalent to 50 ...

Saturn is visible only briefly in early February, but its rings are nearly edge-on. Venus is bright and easily visible throughout February, changing in phase and apparent size. Jupiter shows its moons ...

Astronomers have detected the first tidal disruption event (TDE), designated AT2024tvd, occurring 2,600 light-years outside its host galaxy's core, exhibiting intense, rapidly evolving radio signals.

All the black holes that astronomers have seen fall into one of three categories: stellar-mass black holes, intermediate-mass black holes, and supermassive black holes. Each is more massive than our ...
