Chandra image of BD+30-3639 shows a hot bubble of multimillion degree gas surrounding a dying, Sun-like star that is about 5,000 light years from Earth. The distance across the bubble is roughly 100 times the diameter of our solar system. A planetary nebula is formed when a dying red giant star puffs off its outer layer, leaving behind a hot core that will eventually collapse to form a dense star called a white dwarf. According to theory, a "hot bubble" is formed when a new, two million mile per hour wind emanating from the hot core rams into the ejected atmosphere and heats the interaction region to temperatures of millions of degrees. We are seeing the nebula about a thousand years after it formed. The optical part of this image (orange) was obtained with the Hubble Space Telescope (HST). The hotter, X-ray emitting region (blue, center) was imaged with the Chandra X-ray Observatory (CXO). Both the HST and CXO are telescopes in Earth orbit. BD+30-3639 is around 5000 light years from Earth, in the constellation of Cygnus.
