Eta Carinae is the most luminous star known in our galaxy. It radiates energy at a rate that is 5 million times that of the Sun. Observations indicate that Eta Carinae is an unstable star that is rapidly boiling matter off its surface.

Summary

Description	English: Eta Carinae is the most luminous star known in our galaxy. It radiates energy at a rate that is 5 million times that of the Sun. Observations indicate that Eta Carinae is an unstable star that is rapidly boiling matter off its surface. Some astronomers think that it could explode as a supernova any time! At a distance of 7,000 light years from Earth, this gigantic explosion would pose no threat to life but it would be quite a show.

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it.

Image title	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.
