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 ...

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

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 ...

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 ...

A fiery type of alien world called a “hot Jupiter” can enter a tilted orbit relative to its parent star, and a new study could help puzzled researchers get to the bottom of why. In March, NASA ...

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 ...

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 ...

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 ...

They’re big, full of gas, and have a penchant for hanging out way too close to their parents. These “hot Jupiters” are among the most common extrasolar planets in the galaxy. Here’s what the latest ...

All of the major bodies in our solar system orbit in the same direction our sun rotates, and are roughly in the same plane. This is nicely explained by the process that produced them, a combination of ...

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 ...

A bevy of backward-orbiting exoplanets could challenge theories of planet formation, new research suggests. The planets’ wonky orbits might also rule out the presence of Earthlike bodies in some ...
