"Twins" of Superstar Eta Carinae in Other Galaxies: Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is best known for an enormous eruption seen in the mid-19th century that hurled at least 10 times the sun's mass into space. This expanding veil of gas and dust, which still shrouds Eta Carinae, makes it the only object of its kind known in our galaxy. Now a study using archival data from our Spitzer and Hubble space telescopes has found five objects with similar properties in other galaxies for the first time.
