Hubble Captures Eta Carinae

Hubble’s Space Telescope Imaging Spectrograph (STIS) captured a spectrum (right) of material ejected by a pair of massive stars called Eta Carinae, while the Wide Field and Planetary Camera 2 took an image of the billowing clouds of gas enveloping the stellar pair (left). The spectrum reveals that one of the lobes contains the elements helium (He), argon (Ar), iron (Fe), and nickel (Ni).
