September 9, 2009--Data on chemicals ejected by Eta Carinae are overlaid on a 2008 picture of the dying star taken by the Hubble Space Telescope's previous wide-field camera. A servicing mission to the orbiting telescope this past June installed some new instruments and repaired old ones, including the Space Telescope Imaging Spectrograph, which captured the chemical information.

Last week NASA released some of the first pictures and data taken by the upgraded Hubble, including the Eta Carinae readings.

Among other new Hubble findings: Stellar wind streaming from the star carries away an amount of material equal to our sun's mass every thousand years.
