It took about 50 exploding stars to upend cosmology. Researchers mapped and measured light from Type Ia supernovae, the ...

The fact that Betelgeuse is one of the brightest stars in the sky over Earth, visible with the naked eye, has made it one of ...

Paris, France (AFP)-Since at least the time of the ancient Egyptians, people across the world have gazed up in awe at ...

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 ...

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 ...

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

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.

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 ...

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 ...

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.

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 ...

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.
