Stories about: supernova  

These stars then die as outcasts, astronomers say

Interestingly, the stars are not attached to any galaxy

NGC 6240 formed when two galaxies merged with one another

Well, technically speaking, what they witnessed was a sudden burst of brightness that eventually faded from view

The star that left behind the Sagittarius A East supernova remnant exploded roughly 10,000 years ago, astronomers say

The image, delivered by the Hubble Space Telescope, shows the distant and freakishly old Veil Nebula

Astronomers estimate the star is moving at a speed of about 1,200 kilometers per second (745 miles per second)

The exploded star, located within our home galaxy, was imaged with the help of NASA's Chandra X-ray Observatory

The stars, located at the heart of a planetary nebula dubbed Henize 2-428, will crash some 700 million years from now

Cassiopeia A went kaboom about 340 years ago, spilled loads of insanely hot and radioactive matter into the cosmos

Having sunk its teeth into one of the star's sides, the black hole chocked on the material it was trying to engulf

The burst was produced some 5.5 billion light-years from Earth, scientists are yet to figure out what caused it

The image was obtained with the help of several telescopes, ESA saw it fit to revisit it in time for this holiday season

That means it has an efficiency of 94% to 96%

The stellar explosion occurred in a galaxy located at a distance of about 500 million light-years from our planet

The explosion is a supernova, occurred when the star's sister reached the end of its life

These grains of dust later support the formation of new stars and planets
