Visit my website at [ Ссылка ] - NGC 6559 is a cloud of gas located about 5,000 light-years from Earth, in the constellation of Sagittarius. It neighbor is the much larger and better known Lagoon Nebula (Messier 8). The Danish 1.54-meter telescope located at ESO's La Silla Observatory in Chile has captured this striking view of NGC 6559.
The gas in this cloud is mainly hydrogen, the raw material for star formation. When enough mass accumulates in a region of the nebula, the matter will start to collapse under the weight of its own gravity. Eventually the mass will become so hot and dense, that thermonuclear fusion will begin - marking the birth of a new star.
This video begins by zooming in on the Sagittarius region, past the Lagoon Nebula - eventually keying in on NGC 6559. The video then pans across this brightly shining stellar nursery.
