Sizzling Remains of a Dead Star

"This new view of the historical supernova remnant Cassiopeia A, located 11,000 light-years away, was taken by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. Blue indicates the highest energy X-ray light, where NuSTAR has made the first resolved image ever of this source. Red and green show the lower end of NuSTAR's energy range, which overlaps with NASA's high-resolution Chandra X-ray Observatory.

Light from the stellar explosion that created Cassiopeia A is thought to have reached Earth about 300 years ago, after traveling 11,000 years to get here. While the star is long dead, its remains are still bursting with action. The outer blue ring is where the shock wave from the supernova blast is slamming into surrounding material, whipping particles up to within a fraction of a percent of the speed of light. NuSTAR observations should help solve the riddle of how these particles are accelerated to such high energies

X-ray light with energies between 10 and 20 kiloelectron volts are blue; X-rays of 8 to 10 kiloelectron volts are green; and X-rays of 4.5 to 5.5 kiloelectron volts are red.

The starry background picture is from the Digitized Sky Survey."

    the photonic array of light wave in the electromagnetic spectrum provided an excellent picture.in that part of space,i bet the blast sent pressure that impacted other neighboring planets.i also bet that people do not know that black hole is a concentrated liquid which has a vorticity that moves very fast.ever wonder what makes a black hole?on earth every molecule produces a preasure of 770 atmospheres.in outer space atmosphereic preasure is far less because there are less atoms and molecules.go past our universe and their are no atoms at all!a black hole is space tornado of liquid from outer space to the preasure where their no atoms.the molecules in space are destroyed as they leave are universe,and this imbalance makes a black hole .deep thoughts.....mister shannon ray blake the dungeon master...

    Hey NASA, this 'image' is a 'sizzling star' is certainly not your best art work. If you're going to keep the scientists duped, then you need to quit using the guy renting out the basement apartment for these 'photos'. Evidently he does not have the latest edition of photo-shop.......
