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 ...

"This tangible evidence of a double detonation not only contributes towards solving a long-standing mystery, but also offers ...

MUSE allows astronomers to map the distribution of different chemical elements, displayed here in different colours. Calcium is shown in blue, and it is arranged in two concentric shells. These two ...

In September 2014, when astronomer Iair Arcavi found a new supernova in the night sky, he didn’t think much of it. It looked like any other star that had just died and violently burst apart.

An exploding star has suddenly appeared in the night sky, dazzling astronomers who haven't seen a new supernova so close to our solar system in more than 20 years.

Meanwhile, in another study, astronomers confirmed the discovery of the most distant supernova ever detected — a huge cosmic explosion that took place 10.5 billion years ago or three-quarters ...

Models of the supernova say that the shockwaves should be expanding outward evenly, like a balloon being inflated. However, the researchers noted that one section looks to be exploding in on itself.

A supernova in our galaxy lit up the sky for 8 months in 185 A.D., marking humanity’s first recorded observation. Since then, songs, ballads, novels and movies have been written about supernovas ...

An exploding star has suddenly appeared in the night sky, dazzling astronomers who haven't seen a new supernova so close to our solar system in more than 20 years.

The supernova, named SN 2023ixf, is located 21 million light-years away. ... A supernova exploding in a nearby galaxy is providing an unexpected spectacle for amateur astronomers.

Astronomers say they've discovered a superluminous supernova -- a cosmic explosion so bright it outshines the entirety of the Milky Way's 100 billion stars.

Another star explosion discovered 21 years ago, 1993J in Messier 81, was essentially at the same distance as the new supernova, said International Astronomical Union General Secretary Thierry ...
