Вулканический рельеф на Меркурии Volcanic Terrain on Mercury

Why are many large craters on Mercury relatively smooth inside? Recent images from the robotic MESSENGER spacecraft that flew by Mercury last October show previously uncharted regions of Mercury that have large craters with an internal smoothness similar to the maria on Earth's own Moon.

Глубокое изображение галактики Водоворот Whirlpool Galaxy Deep Field

Follow the handle of the Big Dipper away from the dipper's bowl, until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier's famous catalog.

Телескоп Хаббла в свободном полете Hubble Floats Free

Why put observatories in space? Most telescopes are on the ground. On the ground, you can deploy a heavier telescope and fix it more easily. The trouble is that Earth-bound telescopes must look through the Earth's atmosphere.

Панорама туманности Киля в телескоп Хаббла Carina Nebula Panorama from Hubble

In one of the brightest parts of Milky Way lies a nebula where some of the oddest things occur. NGC 3372, known as the Great Nebula in Carina, is home to massive stars and changing nebula.

Стереоснимок Аполлона-12 и Сервейора-3 Apollo 12 and Surveyor 3 Stereo View

Put on your red/blue glasses and gaze into this dramatic stereo view from the surface of the Moon. The 3D scene features Apollo 12 astronaut Pete Conrad visiting the Surveyor 3 spacecraft in November of 1969. The image was carefully created from two separate pictures (AS12-48-7133, AS12-48-7134) taken on the lunar surface.

К востоку от Антареса East of Antares

East of Antares, dark markings sprawl through crowded star fields toward the center of our Milky Way Galaxy. Cataloged in the early 20th century by astronomer E. E. Barnard, the obscuring interstellar dust clouds include B59, B72, B77 and B78, seen in silhouette against the starry background.

IC 4592: голубая Конская голова IC 4592: A Blue Horsehead

This complex of beautiful, dusty reflection nebulae lies in the constellation Scorpius along the plane of our Milky Way Galaxy. Its overall outline suggests a horsehead in profile, though it covers a much larger region than the better known Horsehead Nebula of Orion.

Ремонт телескопа Хаббла над Землей Above Earth Fixing Hubble

What is that astronaut doing? Fixing the Hubble Space Telescope. During the fourth servicing mission to upgrade and fix Hubble, astronaut Michael Good can be seen attached to the shuttle's robotic arm, working in an open panel of Hubble. Far below, the terminator between day and night can be seen across planet Earth.

Стрелец и центр Млечного Пути Sagittarius and the Central Milky Way

What does the center of our Milky Way Galaxy look like? In visible light, no one knows! It is not possible to see the Galactic center in light our eyes are sensitive to because the thick dust in the plane of our Galaxy obscures it.

Лунные лучи над замком Турсо Moon Rays Over Thurso Castle

What's happening over that castle? While waiting for the Moon to rise last month in Thurso, Scotland, amateur astrophotographer Stewart Watt took a three minute exposure of the background stars. The above image was the surprising result.
