Supernova remnant (SNR) G292.0+1.8, Chandra X-ray image. A supernova remnant is an expanding shell of dust and gas that forms following the explosive death of a massive star. The superheated gas and dust are emitting X-rays, seen as the coloured areas in this image. The relative X-ray energy is is colour-coded: red (low), through orange and green to blue (high). This SNR is around 20,000 light years from Earth, in the constellation Centaurus. Image obtained in 2006, using the ACIS instrument on the Chandra X-ray Observatory (CXO). The optical data (white) is from the Digitized Sky Survey (DSS).
