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 ...

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

Supernova seen from Earth. With all the speculation about what a Betelgeuse supernova would look like from Earth, University of California, Santa Barbara, astronomer Andy Howell got tired of the ...

If SN 2011fe does act as Nugent expects, even people without access to super-high-tech telescopes will be able to see the supernova with small 4-inch telescopes or strong binoculars in really dark ...

The supernova SN2023ixf was discovered just 21 million light years away—essentially next door, ... SN2023ixf is the closest supernova of its kind to Earth to pop off in five years, ...

An explosive star within our galaxy is showing signs of an impending eruption, at least in a cosmic time frame, and has for quite some time. From 1838 to 1858, the star called Eta Carinae ...

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 supernova exploding at such a range probably wouldn't touch off mass extinctions on Earth, Melott said. "People estimated the 'kill zone' for a supernova in a paper in 2003, and they came up ...

The last time Earth felt the effects of a supernova was about 1.7 to 3.2 million years ago. The explosion took place 325 light-years away — 6.5 times farther than the danger zone — but Earth ...

This supernova is thought to have occurred between 163 and 326 light-years away (50–100 parsecs) from Earth. For perspective, our closest stellar neighbor, Proxima Centauri, is 4.2 light-years away.

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 ...
