"A Look to the Heavens"
"The star cluster NGC 3603 lights up a nebula 20,000 light-years from Earth, as seen by the Hubble Space Telescope. Today the team behind the Hubble Space Telescope unveiled a red, white and bluish picture of the NGC 3603 star cluster, 20,000 light-years away in the constellation Carina. The image blends visible-light and infrared observations from the Wide Field Camera 3, which was installed a little over a year ago during NASA's final Hubble servicing mission. The camera focused on the star cluster for a little more than five hours last August and December, using five different filters.
The white starburst comes from NGC 3603's central cluster of huge, hot, fast-burning stars. The red comes from longer-lived, iron-rich stars. And the blue wisps are clouds of gas and dust that have been blasted away by the hot stars' ultraviolet radiation and stellar winds. NGC 3603 serves as a laboratory for studying how massive stars rise and fall."
