The Expansion of Eta Carinae Debris

The Expansion of Eta Carinae Debris

The massive star Eta Carinae (almost hidden in the center) underwent a giant explosion some 150 years ago. The outburst spread the material that is visible today in this very sharp Hubble image. Even though Eta Carinae is more than 8,000 light-years away, structures only 15 thousand million kilometre across (about the diameter of our solar system) can be distinguished. Dust lanes, tiny condensations, and strange radial streaks al appear with unprecedented clarity.

A huge, billowing pair of gas and dust clouds are captured in this stunning Hubble Space Telescope image of the supermassive star Eta Carinae.
