X-rays reveal nature of spiral galaxy's boisterous activity NASA NEWS RELEASE Posted: January 22, 2003
The observation revealed that the nuclear region contains a much higher concentration of neutron stars and black holes than the rest of the galaxy. Also discovered was a cloud of 7 million degree Celsius gas enveloping the nuclear region. The picture that emerges is one of enhanced star formation in the nuclear region that has produced more massive stars, leading to more supernova explosions, neutron stars and black holes. This activity could also account for the hot gas cloud which shows evidence for an excess of carbon, neon, magnesium, silicon and sulfur atoms. Mass evaporating from massive stars, and the ejecta from supernovas have enriched the gas with carbon and other elements. Hot gas with a slightly lower temperature of 4 million degrees was observed along the spiral arms of the galaxy. This suggests that star formation may be occurring at a more sedate rate in the spiral arms, consistent with the observation of proportionately fewer bright point-like sources there compared to the nucleus.
