It might sound weird, but glycerol and water make great analogs for the exploding cloud of supernova matter!
Then those findings were later reviewed, the old location pinpointed, and the remnants of a supernova found.
However, when astronomers had determined that what the Chinese had seen was a supernova, it didn't explain what they could see in modern times.
It is the remnant of a supernova explosion in the year 1054 much more about that during my next lecture and what you see here is not stuff that is generated at this moment in time by the pulsar.
If this is the progenitor of these rare subclass of supernova, we expect to be finding these exotic pairs at the same frequency as the supernova.
Astronomers have suspected for more than a decade that supernova shock waves can act like giant particle accelerators.
Now the galaxy is full of gas and dust, which could hide a distant supernova optically, but the remnant would still produce detectable radio waves and X-rays.
Before we can understand what this "noise" is, we need to understand how equipment designed to look for the space-time ripples caused by collisions between black holes and supernova explosions.
The star then explodes in a so-called Type II supernova.
The unique environment into which this supernova exploded makes it possible for astronomers to observe the condensed dust from the supernova that is usually too cold to emit in the infrared.
This told them it was probably a supernova, and the readings for light energy absorbed by the object and heat dissipated by it strongly implied it was surrounded by dust.
Most recently, those crazy scientists have even recreated a 'supernova' in a test tube!
The supernova explosions that create and spread heavy elements also unleash a torrent of high-energy radiation: gamma rays, X-rays, and ultraviolet light.
This image shows the entire region around the supernova.
The cores of these stars collapse, leading to a violent supernova explosion where the outer layers of the star are expelled into space.
The higher the redshift, the longer light has been traveling and the further back in time the supernova occurred.
A supernova spotted in a nearby galaxy in 1979 appears to have produced the first ever observed baby black hole.
For many it could be a once in a lifetime chance to see a supernova blossom and then fade before their eyes.
Now consider a supernova explosion.
By 2011 debris in the center of the ring, which is about a light-year in diameter, was blazing more intensely as the supernova entered a new stage of stellar demise.
