The James Webb Space Telescope (JWST) has been studying the scene of a dramatic collision between a star and its planet, but ...

Starquakes in stars from cluster M67 reveal hidden pauses that mark major internal changes. These pauses improve how we estimate star ages.

The red giant, roughly 1.12 times the mass of our Sun, orbits the white dwarf every 227 days. The two stars are separated by only 0.54 astronomical units, about the same as the distance from the ...

The stars expand and can engulf nearby planets, effectively incinerating them. In approximately five billion years, Earth’s own sun will turn into a red giant and engulf planets, including our ...

the star wasn’t big or bright enough to be a red giant. It appeared to be a regular star, with only about 70% of the mass of our sun. That changed everything. Instead of being swallowed by a ...

T CrB is a symbiotic binary, a vampire system in which a white dwarf is siphoning material from a red giant star. A white dwarf is the dense, compact core remnant of a once sun-like star ...

Vibrations echoing through giant stars are offering unexpected insights into their internal structures and evolutionary paths. New findings published in Nature and based on data from NASA’s Kepler K2 ...

Enjoy dark skies for evening observing, then catch a meteor shower and a planetary conjunction in the morning sky this week.

Stargazers watched the skies with bated breath on Thursday night in hopes that T Coronae Borealis, a system consisting of a hot, red giant star and a ... will fly by the sun The last recorded ...

A team of UNSW Sydney researchers has unlocked the "sounds" of stars to better understand their age, mass, and evolutionary ...

It comprises a white dwarf and an ancient red giant star. The latter is 1.12 times the mass of our Sun and orbits the white dwarf, which is exerting gravitational pull on the red giant ...
