Data from the Hubble and Spitzer space telescopes suggest that the hot Jupiter WASP-18b has an overabundance of carbon monoxide and little water vapor. The exoplanet may have formed different from other gas giants.

Titanium dioxide, an ingredient used by sunscreens, 'snows' in the hot planet Kepler-13Ab. Astronomers also found that the atmosphere of the exoplanet has a characteristic that is different from other hot Jupiters.

Albedo measurements of the exoplanet WASP-12b suggest that the hot Jupiter, located about 1,400 light years away, appears pitch black. What causes the gas giant to reflect no light?

KELT-16b may only have 550,000 years left before it gets destroyed by tidal forces as it orbits very close to its parent star. A red dwarf star is suspected to be behind the hot Jupiter's death spiral into its host star.

A new study reveals that 'hot Jupiters' may increase in size as they grow older. HAT-P-65b and HAT-P-66b are the two exoplanets that the researches have studied.

Excess number of hot Jupiters were discovered in Messier 67. What's behind the high concentration of these gas giants in the dense star cluster?

Most hot Jupiters have been found to possess atmospheric water, but others appear to be without it. New research by NASA suggests that clouds or haze may play a role in this phenomenon.

A new exoplanet, HD 80606 b, observed by scientists absorbs massive amounts of energy from its host star. It also travels an eccentric path that makes it swing from and to the star.

Astronomers have discovered five new exoplanets similar in characteristics to Jupiter. Using Wide Angle Search for Planets-South Or WASP-South, these exoplanets show distinct characteristics of their own.

Scientists use Kepler space telescope data to discover two giant planets closely orbiting a distant star. The finding of 'hot Jupiter' planets could give clues to how planets form and move, they say.

Tau Boötis b has an atmosphere of carbon monoxide and water, and the giant planet revolves close to its star, making it a hot Jupiter. Although that world is not likely to be home to life, a new technique may find such worlds.
