While astronomers expect many supernova remnants remain to be discovered, the fact that Teleios was spotted at all “is pure luck,” Filipović says. Had it been located closer to the galactic plane, ...

This detailed image of a famous supernova remnant in the constellation Cygnus is the hauntingly beautiful swan song for a massive star.

Pictures of a distant supernova remnant show two concentric rings, providing clear evidence that exploding white dwarf stars ...

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 ...

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 ...

Astronomers have finally caught a dying star in space going out with a bang — and then another bang. The new photographic evidence, captured using the European Southern Observatory’s Very Large ...

When a star dies in a massive explosion, it leaves behind a supernova remnant - an expanding cloud of gas and dust that tells the story of its violent end. Thanks to Hubble’s breathtaking 4K images, ...

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

The explosion of a star, called a supernova, is an immensely violent event. It usually involves a star more than eight times ...
