The Chandra X-ray image shows the complex nature of the region around Eta Carinae, a massive supergiant star that is 7,500 light years from Earth. The outer horseshoe shaped ring has a temperature of about 3 million degrees Celsius. It is about two light years in diameter and was probably caused by an outburst that occurred more than a thousand years ago. The blue cloud in the inner core is three light months in diameter and is much hotter; the white area inside the blue cloud is the hottest and may contain the superstar which is vigorously blowing matter off its surface.
