In the middle of the 19th century, the massive binary system Eta Carinae underwent an eruption that ejected at least 10 times the sun’s mass and made it the second-brightest star in the sky. Now, a team of astronomers has used extensive new observations to create the first high-resolution 3-D model of the expanding cloud produced by this outburst.
