Figuring out the ages of stars is fundamental to understanding many areas of astronomy—yet, it remains a challenge since ...

The newly observed binary system features a cataclysmic variable star, designated GOTO0650, which is in a rarely seen late stage of its evolution. This was also the first major discovery for the ...

Algol is not a single star but a multiple-star system, primarily consisting of two main components, Algol A and Algol B, which orbit a common center of mass. A third, fainter star, Algol C, also ...

The research draws on two existing approaches to better estimate stars’ ages.

The shattered star at the center was once a white dwarf, a stellar ember no larger than Earth, yet almost as heavy as the Sun ...

When it comes to star formation, not all galaxies are the same. Some are quenched, meaning they've depleted their star ...

Trundling along the ecliptic plane in Virgo, our satellite hangs near the bright star Spica in the evening sky.

Astronomers had long been suspecting that some stars do meet their end of life with a dual detonation and new images prove ...

For only the third time in history, astronomers have detected a new interstellar visitor — an object from another star — blitzing into our solar system.

According to a fairly new theory, white dwarfs can explode twice in a row in certain circumstances. For the first time, we ...

Astronomers have captured a jaw-dropping picture of star that exploded twice. It is the first time researchers have obtained ...
