Eta Carinae is located about 7,500 light-years from Earth. In the 1840s, Eta Carinae survived a massive eruption, briefly becoming the second brightest star in the sky. The latest composite image from NASA's Chandra X-ray Observatory and the Hubble Space Telescope shows remnants of that titanic event, hinting that the star may be nearing its final, massive explosion.
