Astronomers have detected a massive, Ultra-Hot Jupiter that’s getting dangerously close to its star. It’s more massive than Jupiter and orbits its star more quickly than Mercury orbits the Sun. There ...

Macquarie University astronomers have tracked an extreme planet's orbital decay, confirming it is spiraling toward its star in a cosmic death dance that could end in three possible ways.

WASP-121b, an already unusual planet, might have a remote origin that explains some of its peculiar properties—from iron rain ...

Long-period giant planets like TOI-4465 b can serve as a bridge between the extreme hot Jupiter exoplanets, which orbit very close to their stars, and the cold gas giants in our own solar system.

Astronomers have discovered the strange dance that leads to the creation of rare "double hot Jupiters" in binary star systems that are "just right." ...

The 1995 discovery of the first hot Jupiter (known as 51 Pegasi b) earned two Swiss astronomers the Nobel Prize in physics in 2019 and led to a wave of exoplanet discoveries that continues to the ...

Scientists have scored a pristine view of a pair of exotic worlds orbiting a star more than 300 light-years away — one with sand-like clouds and another surrounded in space by moon-making material.

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected three new hot Jupiter exoplanets orbiting three distant K dwarf stars. The finding was ...

NASA's Webb telescope glimpses coldest exoplanet yet found: What to know about gas giant An exoplanet 60 light-years away from Earth, known as 14 Herculis c, is thought to be as cold as 26 degrees ...

A team of international scientists recently published the discovery of nine new hot Jupiter exoplanets in The Astronomical Journal that could help scientists better understand the formation and ...
