The supernova that just won't fade away
ESA Portal - The supernova that just won't fade away
Amazing how this star has given us data, on it's own output of stellar wind, for the past 16,000 years, all because it went SuperNova in 1979.
The supernova shockwaves keep spreading out, and catching up with the stellar wind given off thousands of years ago. When the two collide, the stellar wind particles get heated to MILLIONS of degrees, and this extreme energy input generates x-ray light from the particles.
The scientists have been able to determine that the stellar wind emitted 16,000 years ago, has a density of 10,000 atoms per cubic centimeter -- 1000 times more dense than the wind emitted from our sun -- Sol.
This process will probably continue, and illuminate stellar winds that came off that star even further back in time, beyond 16,000 years ago.
