NGC 869 & NGC 884: двойное звездное скопление NGC 869 & NGC 884: A Double Open Cluster

Most star clusters are singularly impressive. But open clusters NGC 869 and NGC 884 are doubly impressive. Also known as "h and chi Persei", this rare double cluster, shown above, is bright enough to be seen from a dark location without even binoculars.

Рассеянное скопление M50 Open Cluster M50

Many stars form in clusters. Two types of star clusters are visible in our Milky Way Galaxy: open clusters and globular clusters. Open clusters like M50, shown above, typically contain hundreds of stars, many of which are bright, young, and blue.

Удивительный солнечный протуберанец A Prominent Solar Prominence

One of the most spectacular solar sights is a prominence. A solar prominence is a cloud of solar gas held above the Sun's surface by the Sun's magnetic field. The Earth would easily fit under one of the loops of the prominence shown in the above picture.

Полярные сияния и созвездие Ориона Aurora and Orion

Looking toward the south from low Earth orbit, the crew of the Space Shuttle Endeavor made this stunning time exposure of the Aurora Australis or southern lights in April of 1994. Aurora are visible at high northern latitudes as well, with the northern lights known as Aurora Borealis.

M51: галактика Водоворот M51: The Whirlpool Galaxy

The Whirlpool Galaxy is a classic spiral galaxy. At only 15 million light years distant, M51, also cataloged as NGC 5194, is one of the brighter and more picturesque galaxies on the sky.

Файер-бол сверхновой 1987А разрешен Supernova 1987a Fireball Resolved

Ten years ago the most notable supernova of modern times was observed. In February 1987, light reached Earth from a star which exploded in the nearby Large Magellanic Cloud galaxy. Supernova 1987a remains the closest supernova since the invention of the telescope.

Торнадо в туманности Лагуна Twistin' by the Lagoon

The awesome spectacle of starbirth produces extreme stellar winds and intense energetic starlight -- bombarding dusty molecular clouds inside the Lagoon Nebula (M8). At least two long funnel shaped clouds, each roughly half a light-year long, have apparently been formed by this activity.

Скопление галактик A2199 Galaxy Cluster A2199

It's bigger than a bread box. In fact, it's much bigger than all bread boxes put together. Abell 2199 is huge. In fact, it is a close, large cluster of galaxies, containing several thousands of galaxies centered around a central dominant galaxy.

Путешествие в центр Галактики Journey to the Center of the Galaxy

In Jules Verne's science fiction classic A Journey to the Center of the Earth, Professor Hardwigg and his fellow explorers encounter many strange and exciting wonders. What wonders lie at the center of our Galaxy?

Земля проходит мимо астероида Тутатис Earth Nears Asteroid Toutatis

On November 29, 1996 the Earth came within 3.3 million miles of the asteroid Toutatis. Above is a computer simulated picture of this spectacle from the surface of Toutatis (a 2.5 degree field of view looking toward Earth). In Earth's sky, Toutatis appeared only as a faint object moving against a background of stars.
