Карта гамма-всплесков на небе BATSE GRB Final Sky Map

What causes the most powerful explosions in the universe? The BATSE modules that flew on the Compton Gamma Ray Observatory allowed more insight into enigmatic gamma-ray burst (GRB) explosions than ever before. From 1991-2000, BATSE detected 2704 GRBs, much more than ever previously recorded.

M63: Галактика Подсолнух M63: The Sunflower Galaxy

One of the bright spiral galaxies visible in the north sky is M63, the Sunflower Galaxy. M63, also catalogued as NGC 5055, can be found with a small telescope in the constellation of Canes Venaciti.

Кольцевая Планетарная Туманность Shapley 1 Shapley 1: An Annular Planetary Nebula

What happens when a star runs out of nuclear fuel? The center condenses into a white dwarf while the outer atmospheric layers are expelled into space and appear as a planetary nebula. This particular planetary nebula, designated Shapley 1 after the famous astronomer Harlow Shapley, has a very apparent annular ring like structure.

Солнечный свет на кольцах Сатурна Sunlight Through Saturns Rings

Normally, earth-bound astronomers view Saturn's spectacular ring system fully illuminated by reflected sunlight.

The three bright ring features are visible because the rings themselves are not solid.
