Ancient supernovas may have blasted Earth with powerful radiation, causing dramatic changes in our climate, and could do so ...

The model captures the dynamic interaction between BP Tau and its environment, highlighting dramatic flares — intense bursts of energy — detected by NASA's Chandra X-ray Observatory.

Supernovae, these gigantic stellar explosions, release a phenomenal amount of energy. This energy travels through space, capable of reaching planets located thousands of light-years away.

Now, a new study has for the first time described SN 1181 in detail by creating a computerized model of the supernova’s evolution from immediately after the initial outburst appeared until today.

In the second model, the star suffered a violent pre-supernova explosion that sent gas weighing up to one-tenth the mass of the sun into orbit in less than a year. Related stories: ...

I feel it should be pointed out that the supernova model has alot of assumptions in it. While we can claim X level of sigma, thats only the uncertainties that we understand. If any assumptions are ...

"Combining the DES supernova information with these other probes will even better inform our cosmological model," said Davis. "Even if we measure dark energy infinitely precisely, it doesn't mean ...

Radioactive isotopes found in meteorites suggest a supernova went off right near the Sun as it was forming – but that should have blasted the young solar system away. So how did we survive? A ...
