When Star Wars debuted in 1977, astronomers had yet to confirm an exoplanet with the same orbital path as Skywalker’s home world. It would take another 16 years before experts located an actual ...

Researchers have developed a new coronagraph that could make it possible to see distant exoplanets obscured by light from their parent stars. Researchers have developed a new coronagraph -- an ...

Scientists discover life-sustaining molecules in exoplanet K2-18b’s atmosphere – Located 124 light-years away, using NASA’s JWST Scientists have detected molecules associated with biological ...

Scientists have found further evidence of possible biosignature gases on the nearby exoplanet K2-18b, strengthening the case that it could support alien life. In 2023, researchers using NASA's ...

If one of these missions were to discover life on an exoplanet, i.e., a planet outside of our solar system, this would be a sensational finding with implications far beyond science and would ...

But not everyone agrees that it signals life. An illustration shows what exoplanet K2-18b might look like based on data from NASA's James Webb Space Telescope. K2-18b is 8.6 times as massive as ...

In a striking new finding, astronomers have uncovered what they say is the strongest evidence yet of life existing beyond our solar system. Using the James Webb Space Telescope, researchers from ...

Several false alarms — including the TRAPPIST-1 system, the exoplanet WASP-12b, and even Venus — have taught scientists to triple-check such claims before accepting them.

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 ...

The most likely reason (when combined with other observation) for seeing 1000 times more of the chemical DMS would be that exoplanet K2-18B is an ocean planet teeming with life. This ocean filled with ...
