The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It forms the visible parts of the Cygnus Loop, a supernova remnant, many parts of which have received their own individual names and catalog identifiers. The source supernova was a star 20 times as massive as the sun and exploded 10.000 to 20.000 years ago. The remains have since expanded to cover an area of ​​the sky approximately 3 degrees in diameter. While previous distance estimates were between 1200 and 5800 light years, a recent determination of 2400 light years is based on direct astrometric measurements. The eastern part of this SNR is sometimes called the Bat Nebula and is made up of NGC 6995 and NGC 6992.
