Пеликан в Лебеде A Pelican in the Swan
30.11.2006

The Pelican Nebula lies about 2,000 light-years away in the high flying constellation Cygnus, the Swan. Also known as IC 5070, this cosmic pelican is appropriately found just off the "east coast" of the North America Nebula (NGC 7000), another surprisingly familiar looking emission nebula in Cygnus.

2.09.1996

Sirius is the brightest star in the night sky. Intrinsically, Sirius is over 20 times brighter than our Sun and over twice as massive. As Sirius is 8.7 light years distant, it is not the closest star system -- the Alpha Centauri system holds this distinction.
