My NASA pic of the week

I like working at NASA because the projects I support do some really amazing things.  This is supernova remnant W49B; sorry, I don’t know if it has a cool name or not. Scientists (grad students, actually) at the Suzaku observatory detect X-ray emissions created as free electrons get deflected or captured by nuclei of atoms. The thing is, it took a lot of energy to get those electons free of the nuclei in the first place. Something like 30 to 100 million degrees fahrenheit, or 10,000 times hotter than the surface of our Sun. The supernova that creates such heat also expands out into thin space so that it takes thousands of years for nuclei to find their missing electrons, and we can detect the X-rays today. More info about these “fossil fireballs” is over at the mission page for the Suzaku satellite.

This it NOT an official NASA image of the day.
