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 ...

Hot Jupiters rank among the strangest planets astronomers have ever found. They are gas giants as massive as Jupiter, yet they race around their stars in just a few days. Since the first such world ...

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 Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Astronomers may have inadvertently complicated the mystery of how strange "roasting marshmallow" planets form. Using the ...

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 ...

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 ...

Hot Jupiters are giant planets initially known to orbit alone close to their star. During their migration towards their star, these planets were thought to accrete or eject any other planets present.

Combined chemical and hydrodynamic modeling offers a powerful tool beyond Jupiter. Scientists can apply similar techniques to ...
