A mysterious object has caused a long-lasting and extreme dimming of a distant star, but is this object a 'failed star' brown dwarf, or an exceptionally massive super-Jupiter exoplanet?

The balloon-based EXCITE mission measures infrared phase curves of hot Jupiter exoplanets to map temperature and atmospheric composition from long-duration Antarctic flights.

Worlds like Tatooine—the iconic twin-sun planet from Star Wars—are no longer confined to science fiction; they have entered ...

An exoplanetary system about 116 light-years from Earth could flip the script on how planets form, according to researchers who discovered it using telescopes from NASA and the European Space Agency, ...

In A Nutshell A massive star in the Andromeda Galaxy faded by more than 10,000 times over a decade and vanished from view, likely collapsing into a black hole without exploding as a supernova ...
