"Throwing a close companion into the mix could possibly wreak further havoc on the already complicated processes surrounding ...

Close companions can influence stellar evolution in many ways. While some companions can be detected around young stellar ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered that aging stars in their so-called "red giant" phase are even more destructive to their orbiting planets than ...

This extreme expansion poses a serious threat to nearby planets. For example, when the Sun becomes a red giant in about 5 ...

The Earth will be swallowed by the Sun, or torn to pieces - a bleak prospect recently proposed by scientists, but in the very distant future.

When stars like the Sun run out of hydrogen in their cores, fusion slows and the outer layers balloon outward. The star can swell up to 1,000 times its original size, marking the start of the red ...

Recent observations of a dying star have offered a chilling glimpse into the cataclysmic fate that awaits Earth billions of ...

The study finds that when a star leaves its stable main-sequence stage, nearby planets begin to be pulled inward, a process ...

The discovery throws light on how giant or dying stars behave with their surroundings and other objects around them.

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA’s TESS telescope to study nearly half a million stars, scientists ...

Astronomers say they spotted signs of a giant explosion releasing from a star beyond our solar system, one powerful enough to destroy a planet’s atmosphere.

The study suggests that planets closest to their stars, especially those that orbit their stars in just 12 days or less, are at a higher risk of being sent to their doom by their aging suns.
