A star located about 1,300 light-years from Earth shows signs of having devoured one of its planets — and is now gearing up ...

Of all the strange worlds in our Milky Way galaxy, some of the most mysterious are those hanging around white dwarf stars.

Astronomers found nearby exoplanet GJ 3378b may be more Earth-like than thought, strengthening its chances of supporting life ...

New research using NASA's powerful JWST telescope has identified a planet 41 light years away which may have an atmosphere. The planet is within the "habitable zone," the region around a star where ...

Our Sun is about halfway through its life, which means Earth is as well. After a star exhausts its hydrogen nuclear fuel, its diameter expands more than a hundredfold, engulfing any unlucky planets in ...

For the first time, NASA's TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting ...

WD 1856 b is the only confirmed case of a planet that survived the death of a Sun-like star. It’s a Jupiter-size world ...

A small, rocky world orbiting a red dwarf star roughly 48 light-years from Earth has become the focus of a new study challenging assumptions about what makes a planet capable of supporting life. The ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...

Astronomers are investigating a strange class of exoplanets known as eccentric warm Jupiters — massive gas giants that orbit their stars in unexpected, elongated paths. Unlike their close-orbiting ...

Dying stars may be wiping out nearby giant planets as they expand into red giants. Astronomers found that these close-in planets become increasingly rare around more evolved stars, suggesting many ...

A step-by-step explanation for why planets that orbit a double star eventually enter an unstable orbit and disappear from the system. Of the more than 4,500 stars known to have planets, one puzzling ...
