When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, ...

Strange giant planets known as hot Jupiters, which orbit close to their suns, got kicked onto their peculiar paths by nearby planets and stars, a new study finds. After analyzing the orbits of dozens ...

Astronomers may have uncovered the curious origins of the universe's most curious planets, so-called "double hot Jupiters." The team behind the research hopes their discovery will help find more of ...

The Hubble Space Telescope has been used to study 25 hot Jupiters. It has helped to answer "questions important to our ...

Since the first hot Jupiter was discovered in 1995, astronomers have been trying to figure out how the searing-hot exoplanets formed and arrived in their extreme orbits. Johns Hopkins University ...

Recent research challenges the prevailing theory that hot Jupiters (gas giants orbiting close to their stars) form through a disruptive process that prevents the existence of smaller planets in the ...

Astronomers challenge longstanding beliefs about the isolation of 'hot Jupiters' and proposes a new mechanism for understanding the exoplanets' evolution. Research led by an Indiana University ...

A recent study of rocky worlds orbiting their star in only a handful of days suggests that these ‘hot Earths’ may be stripped-down cores of gas giants, created by a process that depends on how their ...

After less than a year in operation, NASA's Kepler space telescope finds five new exoplanets in our galaxy. Unfortunately, none of them is habitable. CNET contributor Don Reisinger is a technology ...

The largest study of known exoplanets yet has found that clouds are hiding the signs of water on hot Jupiters. Since the search for planets outside our Solar System began, scientists have found ...

Blame the 'hot Jupiters.' These large, gaseous exoplanets can make their suns wobble when they wend their way through their own solar systems to snuggle up against their suns, according to new ...
