Eta Carinae debris

The furious expansion of a huge, billowing pair of gas and dust clouds are captured in this comparison image of the supermassive star Eta Carinae. Even though Eta Carinae is more than 8000 light-years away, structures only 15 thousand million kilometres across (about the diameter of our Solar System) can be distinguished in this sharp Hubble image. Dust lanes, tiny condensations, and strange radial streaks all appear with unprecedented clarity.
