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 ...

Betelgeuse needs no introduction. Besides having its name borrowed by the ghost with the most, this 10-million-year-old red ...

Violent supernova explosions triggered at least two mass extinctions on Earth in the distant past, experts believe, but the imminent, smaller, explosion of T Coronae Borealis is believed to be too ...

A supernova is one of the most powerful and awe-inspiring events in the universe. It marks the violent death of a star, and ...

According to the team's calculations, about one supernova happens every 400 million years within close enough vicinity to Earth that its radiation could impact the atmosphere.

Earth seems to have entered this bubble about 6 million years ago. Passing through the outer wall, where radiation would have been concentrated, could have accounted for the older spike in iron-60 ...

Scientists have confirmed what became of a star that exploded in a stunning supernova visible to Earth more than three decades ago: It morphed into a neutron star, one of the oddest objects in the ...

They believe a supernova explosion close to Earth could be to blame for both the late Devonian and Ordovician extinction events, which occurred 372 and 445 million years ago respectively.

The explosive supernova deaths of nearby massive stars may have played a significant role in triggering at least two mass extinction events in Earth's history, according to new research.
