In a nutshell A massive supernova explosion 13,000 years ago may have triggered the Younger Dryas ice age by damaging Earth’s ozone layer with deadly radiation. The cosmic blast likely ...

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

SN2023ixf is the closest supernova of its kind to Earth to pop off in five years, and the second closest in the past decade, according to NASA.

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 ...

An artist's impression of a supernova exploding near the ancient Earth NASA/CXC/M. Weiss Astrophysicists have done a bit of crime scene investigation on what’s almost a reverse murder mystery.

A huge surge of gamma-ray energy from space caused electric currents to flow through the surface of the Earth on October 9, scientists have said.. This gamma-ray burst, named GRB221009A, is the ...

To estimate how close a supernova would have to be to cause serious damage to Earth, we must look at a supernova's destructive capabilities. First, there's the shock wave from the explosion itself.

That supernova was perhaps 300 light years from us, closer than Betelgeuse, but far enough to cause no major problems for life on Earth. A very close supernova, closer than 30 light years, could ...

To estimate how close a supernova would have to be to cause serious damage to Earth, we must look at a supernova's destructive capabilities. You may like Supernovas may have triggered life ...

A new paper suggests that a star some 65 light-years from Earth may have exploded into a supernova, and that when the blast reached Earth it degraded our planet’s atmosphere.
