The furious expansion of a huge, billowing pair of gas and dust clouds are
captured in this Hubble Space Telescope comparison image of the
supermassive star Eta Carinae.
To create the picture, astronomers aligned and subtracted two images of Eta
Carinae taken 17 months apart (April 1994, September 1995). Black represents
where the material was located in the older image, and white represents the
more recent location.
