Покрытые кратерами ледяные утесы на спутнике Сатурна Тефии Cratered Cliffs of Ice on Saturns Tethys

The surface of Saturn's moon Tethys is riddled with icy cliffs and craters. The most detailed images ever taken of Tethys were captured late last month as the robot Cassini spacecraft swooped past the frozen ice moon.

NGC 869 и NGC 884: двойное рассеянное скопление NGC 869 and NGC 884: A Double Open Cluster

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

Кружащиеся штормы на Сатурне The Swirling Storms of Saturn

Storms larger than hurricanes continually dot the upper atmosphere of the planet Saturn. A view of many storms occurring simultaneously was captured in July by the robot Cassini spacecraft now orbiting Saturn. An image of unusually high detail was made possible at that time when Cassini isolated a very specific color of polarized infrared light.

СоюзTMA 2 на борту ракеты R7 Rollout of Soyuz TMA 2 Aboard an R7 Rocket

It takes a big rocket to go into space. In 2003 April, this huge Russian rocket was launched toward Earth-orbiting International Space Station (ISS), carrying two astronauts who will make up the new Expedition 7 crew.

Пекулярные галактики Arp 295 Peculiar Arp 295

A spectacular bridge of stars and gas stretches for nearly 250,000 light-years and joins this famous peculiar pair of galaxies cataloged as Arp 295. The cosmic bridge between the galaxies and the long...

Затмение в Мадриде Eclipse Madrid

A walk in the park seemed like a perfect idea to many enjoying a sunny October morning in Madrid, Spain. Of course, on October 3rd an added attraction was the Moon - seen in dramatic silhouette during an annular solar eclipse.

Спиральная галактика NGC 1350 Spiral Galaxy NGC 1350

This gorgeous island universe lies about 85 million light-years distant in the southern constellation Fornax. Inhabited by young blue star clusters, the spiral arms of NGC 1350 seem to join in a circle around the galaxy's large, bright nucleus - giving the galaxy the appearance of a limpid cosmic eye.

Кольцеобразное солнечное затмение: вид с высоким разрешением An Annular Solar Eclipse at High Resolution

On Monday, part of the Sun went missing. The missing piece was no cause for concern -- the Moon was only momentarily in the way. The event was not a total eclipse of the Sun for any Earth-bound sky enthusiast but rather, at best, an annular eclipse, where the Moon blocked most of the Sun.

Пыль и звезды Млечного Пути The Milky Way in Stars and Dust

The disk of our Milky Way Galaxy is home to hot nebulae, cold dust, and billions of stars. This disk can be seen from a dark location on Earth as a band of diffuse light across the sky.

Гиперион: спутник Сатурна со странными кратерами Saturns Hyperion: A Moon with Odd Craters

What lies at the bottom of Hyperion's strange craters? Nobody knows. To help find out, the robot Cassini spacecraft now orbiting Saturn swooped past the sponge-textured moon again last week and took an image of unprecedented detail.
