Summary

Description
English: Optical/Infrared/X-ray comparison for the planetary nebula BD+30 3639 The planetary nebula was formed when a ring of gas and dust was ejected by a dying red giant star about a thousand years ago. The optical (left) shows gas in the ring that has been heated to 30,000 degrees Celsius that has been heated by ultraviolet radiation from the central star. The infrared image (middle) shows radiation from dust grains at a temperature of -170 degrees Celsius. The Chandra X-ray image (right) shows a 3 million degree Celsius cloud that appears to fit inside the rim of gas and dust seen in the optical and infrared images.
