Supernova in Sagittarius

The Spitzer Space Telescope website is dance massive for outrageous, downloadable space photography -- all infrared.

This is the billowing bubble from a very old Supernova in Sagittarius that is invisible to telescopes at visible light frequencies due to the massive dust clouds at the center of the Milky Way. It is about 10,800 light years from Earth. Infrared telescopes, like the Earth Orbiting Spitzer telescope, can see through all the dust in the center of our galaxy and show us what is there for the first time.


As in Infrared Warm-Cool-Not Hot but Warmish Cool.
