The discovery of an extraordinary multi-planet system has demonstrated that so-called "hot Jupiter" planets may not be lonely giants after all. The findings could force scientists to revise their ...

Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet surveys suggest that just four layouts may dominate the universe. Drawing on ...

Do all exoplanets known as “hot” Jupiters orbit alone in their respective solar systems, as has long been observed? This is what a recent study published in Astronomy & Astrophysics hopes to address ...

The WASP-132 system contains a Hot Jupiter (in the foreground), an inner super-Earth (here transiting in front of the orange host star) and the planet WASP-132d, discovered towards the outside of the ...

Hot Jupiters – giant gas planets that race around their host stars in extremely tight orbits – have become a little bit less mysterious thanks to a new study combining theoretical modeling with ...

BOULDER, Colo. — Planets known as Hot Jupiters get their name from the very turbulent environments in which they exist. They are exoplanets (planets outside of the Solar System) that are all in very ...

For centuries, the solar system was viewed as a standard blueprint for planetary systems in the universe, with a star (our sun) at the center of a circular track, and a planet orbiting within each ...

Astronomers just discovered a gas giant on its way to becoming a hot Jupiter — and it’s extremely weird. An exoplanet on a twisted, backwards orbit may offer clues about how hot Jupiters (giant gas ...

The first exoplanet ever discovered in 1995 was what we now call a “hot Jupiter”, a planet as massive as Jupiter with an orbital period of just a few days. Today, hot Jupiters are thought to have ...
