Studies based on observations from NASA's Hubble Space Telescope show that hot Jupiters, exoplanets around the same size as Jupiter that orbit very closely to their stars, often have cloud or haze layers in their atmospheres.
The super-Earth exoplanet 55 Cancri e, depicted with its star in this artist's concept, likely has an atmosphere thicker than Earth's but with ingredients that could be similar to those of Earth's atmosphere.
This artist's illustration of the exoplanet LHS 3844b, shows the planet's surface may be covered mostly in dark lava rock, with no apparent atmosphere, according to observations by NASA's Spitzer Space Telescope.
A transmission spectrum made from a single observation using Webb’s Near-Infrared Imager and Slitless Spectrograph (NIRISS) reveals atmospheric characteristics of the hot gas giant exoplanet WASP-96 b.
WFIRST, the Wide Field Infrared Survey Telescope, is shown here in an artist's rendering. It will carry a Wide Field Instrument to provide astronomers with Hubble-quality images covering large swaths of the sky.
A NASA-led team of scientists determined that WASP-18b, a 'hot Jupiter' located 325 light-years from Earth, has a stratosphere that's loaded with carbon monoxide, but has no signs of water.
