Scientists have captured their best view yet of how extreme magnetic fields shape superfast jets from the most powerful explosions in the universe.
On April 27, a powerful flash of radiation erupted from deep space -- the gamma-ray burst was the brightest on record, challenging some of the leading theories on how the most powerful explosions in the known Universe occur. Continue reading →
Gamma ray bursts (GRBs) are some of the most powerful explosions in the Universe -- now a new GRB has been spotted from a time in the Universe's history when galaxies were just beginning to form. Continue reading →
Although they may shine for many billions of years, stars like our sun don't last forever and when it's time for them to fizzle away into the night they most certainly don't go gently -- but the result can be quite beautiful.
A rare isotope of iron found in fossilised bacteria under the Pacific ocean gives clues to a near-Earth supernova which exploded 2.2 million years ago. Continue reading →
Astronomers working on a multi-year program with the Hubble Space Telescope have announced the discovery of the most distant supernova ever observed, a stellar explosion that occurred over 10 billion years ago. ->
With the help of NASA's brand new NuSTAR observatory, astronomers have measured the spin of a supermassive black hole by detecting the relativistic effects that warp space-time at the edge of its event horizon.
When it's setting up a powerful shockwave in space made up of high-speed particles accelerated to nearly the speed of light, that's when! ->
