Starbirth region NGC 3324. Hubble Space Telescope (HST) image of the edge of a nebula in the starbirth region NGC 3324. This is a region where nebulae (dust and gas clouds) glow under the impact of radiation from newly formed stars. The colours indicate three chemical elements: red shows emission from sulphur, green from hydrogen, and blue from oxygen. NGC 3324 is located in the constellation of Carina and is around 7200 light years from Earth. The area seen here is around 13.4 light years across. This image was obtained in 2006 and 2008, using HST's Wide Field Planetary Camera 2 (WFPC2) and the Advanced Camera for Surveys (ACS).
