Anew analysis suggestsa distant planet outside our solar system has water in its atmosphere. The discovery of evidence of water coincides with theories predicting its presence in the atmosphere of ...

Atmospheric characterization of directly imaged planets has thus far been limited to ground-based observations of young, self-luminous, Jovian planets. Near-term space- and ground- based ...

The breakthrough could one day help scientists detect life on those extrasolar worlds, or exoplanets, the U.S. National Aeronautics and Space Administration said late Tuesday.

If we look at the gas giant planets in our solar neighborhood, we see a clear pattern; the more massive the planet, the lower the percentage of “heavier” elements (anything other than hydrogen and ...

Researchers observed exoplanet GJ 1214b's atmosphere by measuring the heat it emits while orbiting its host star. Astronomers directly detected the light emitted by a sub-Neptune exoplanet -- a ...
