Caption: This is a Hubble Space Telescope image of the massive binary star system Eta Carinae taken in 1995. The pair of stars is hidden, but give off the white-blue glow at the center of the image. The hourglass shape is due to two huge lobes of gas expanding outward, a product of the mid-1800s Great Eruption that was studied as a light echo in Rest, et al.
