A supernova, the explosion of a white-dwarf or massive star, can create as much light as billions of normal stars. This transient astronomical phenomenon can occur at any point after a star has reached its final evolutionary ...
Astronomers have used NASA's Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of ...

Using the smoothed particle inference (SPI) technique, astronomers have investigated the supernova remnant (SNR) DEM L71, mainly analyzing the X-ray emission from this source. Results of the study, presented in a paper published ...
Using ESA's XMM-Newton spacecraft, astronomers have investigated the nature of a peculiar pulsar wind nebula (PWN) in the supernova remnant (SNR) CTB 87. Results of the study, presented in a paper published November 26, shed ...
The leftovers from a spectacular supernova that revolutionised our understanding of how stars end their lives have finally been spotted by astronomers at Cardiff University.

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this "new star" was far beyond ...
