- This NASA Hubble Space Telescope image of the core of the nearest
- starburst spiral galaxy, NGC 253, reveals violent star formation
- within a region 1,000 light-years across. A starburst galaxy has an
- exceptionally high rate of star birth, first identified by its excess
- of infrared radiation from warm dust. Hubble's high resolution allows
- astronomers to quantify complex structures in the starburst core of the
- galaxy for the first time, including luminous star clusters, dust lanes
- which trace regions of dense gas and filaments of glowing gas. Hubble
- identifies several regions of intense star formation, which include a
- bright, super-compact star cluster. These observations confirm that
- stars are often born in dense clusters within starbursts, and that
- dense gas coexists with and obscures the starburst core. This image
- was taken with Hubble's Wide Field Planetary Camera 2 (in PC mode).
