For the first time, astronomers have spotted a star that exploded not once, but twice. A new image of a roughly 300-year-old supernova provides visual evidence that some dying stars undergo a double ...

In October 1604, astronomer and mathematician Johannes Kepler spotted a new star in the sky and began tracking it. Over the course of several weeks, the star remained visible in the daytime and ...

Stars often die with a final burst of beauty. For the first time, astronomers have captured visual proof that a star can ...

Named GW 231123 after the date it was recorded on 23 November 2023, it's the most massive black hole collision we've seen yet ...

Very massive stars (VMSs) have had a massive impact on the formation of our universe. However, there aren't very many of them ...

In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring ...

Using a combination of telescopes, astronomers have characterized the closest supernova linked to a fast X-ray transient. The ...

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 ...

A new study of a star undergoing the throes of a supernova death has revealed that bursts of X-radiation known as fast-X-ray ...

Low-mass stars like our Sun expel their outer layers as a planetary nebula because of what is going on in the star’s core as it ages.

There’s a chance we could see a white dwarf star explosion this year. T Coronae Borealis, a binary star system and recurrent nova located roughly 3,000 light-years from Earth, is expected to erupt ...

To date, the collaboration has detected dozens of merger events since its first Nobel Prize-winning discovery. Early detected ...
