NGC 1929 in 60 Seconds - Chandra X-ray Observatory [HD]

video about telescope






The star cluster known as NGC 1929 is embedded in a cloud of gas and dust, which astronomers call the N44 nebula. Many new stars, some of them very massive, are forming within this star cluster. These massive stars produce intense radiation, expel matter at high speeds, and race through their evolution to explode as supernovas. The winds and supernova shock waves carve out huge cavities called superbubbles in the surrounding gas. X-rays from NASA's Chandra X-ray Observatory show hot regions created by these winds and shocks. Meanwhile, infrared data from NASA's Spitzer Space Telescope outline where the dust and cooler gas are found. An optical light image from a European Space Observatory telescope in Chile shows where ultraviolet radiation from hot, young stars is causing gas in the nebula to glow.
