 |  NASA’s Spitzer, Hubble Find ’’Twins’’ of Superstar Eta Carinae in Other Galaxies
 15 January 2016
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 NASA’s Spitzer and Hubble space telescopes has found
five objects with similar properties in other galaxies.
