NASA’s Curiosity rover has made a major discovery that could help explain what happened to Mars’ ancient atmosphere—and why the planet became so dry and lifeless. For years, scientists have ...

or a potentially habitable planet entirely covered in liquid water with a hydrogen-rich atmosphere. “Given everything we know about this planet, a Hycean world with an ocean that is teeming with ...

Using the James Webb Space Telescope, the team detected chemical fingerprints within the atmosphere of K2-18b that suggest the presence of dimethyl sulfide or DMS, and potentially dimethyl ...

Using the James Webb Space Telescope, a British-U.S. team of researchers detected signs of two chemicals in the planet's atmosphere long considered to be "biosignatures" indicating ...

Astronomers, led by the University of Cambridge, have used data from the James Webb Space Telescope (JWST) to detect the fingerprints of alien life in the atmosphere of a distant planet. Scientists ...

Scientists have reported new observations from NASA’s James Webb Space Telescope (JWST) that strengthen the case that the exoplanet K2-18 b has molecules in its atmosphere that, on Earth ...

Using the James Webb Space Telescope, a British-US team of researchers detected signs of two chemicals in the planet's atmosphere long considered to be "biosignatures" indicating extraterrestrial life ...

Using data from the James Webb Space Telescope (JWST), the astronomers, led by the University of Cambridge, have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide ...

While an unknown chemical process may be the source of these molecules in K2-18b's atmosphere, the results are the strongest evidence yet that life may exist on a planet outside our solar system.

and when those tiny particles — some no bigger than a grain of sand — enter the planet's atmosphere at around 30 miles per second (49 kilometers per second), they burn up and create bright ...

Lightning is expected to become more frequent and intense as the atmosphere warms. One 2014 study projected a 12% increase in lightning frequency for every 1°C rise in global temperature.
