Лунный вездеход Аполлона 17 Apollo 17's Lunar Rover

In December of 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt spent about 75 hours exploring the Moon's Taurus-Littrow valley while colleague Ronald Evans orbited overhead. Cernan and Schmitt were the last humans to walk or ride on the Moon - aided in their explorations by a Lunar Roving Vehicle.

Северный Джемини: NGC 6934 NGC 6934 from Gemini North

What's going on near the center of globular cluster NGC 6934? The blur caused by the Earth's atmosphere has prevented astronomers from discerning individual stars in this unusual environment. Telescopes in space can help, but the new Gemini North telescope took the above picture from the ground.

Начал работу телескоп Северный Джемини Gemini North Telescope Inaugurated

A new mammoth telescope has begun to inspect the northern sky. The 8-meter Gemini North telescope, pictured above, was dedicated last week in Hawaii, with images documenting its unprecedented abilities being released. Within two years, sister telescope Gemini South will begin similar observations of the southern sky from Chile.

С Марса с любовью From Mars with Love

Are Martians trying to tell us something? An indentation has been recently photographed on Mars that resembles a heart, a common human symbol for love. Because intelligent Martians have never been known to exist...

Диполь COBE: движение сквозь Вселенную COBE Dipole: Speeding Through the Universe

Our Earth is not at rest. The Earth moves around the Sun. The Sun orbits the center of the Milky Way Galaxy. The Milky Way Galaxy orbits in the Local Group. The Local Group falls toward the Virgo Cluster of Galaxies.

Оболочки туманности Яйцо Shells in the Egg Nebula

The Egg Nebula is taking a beating. Like a baby chick pecking its way out of an egg, the star in the center of the Egg Nebula is casting away shells of gas and dust as it slowly transforms itself into a white dwarf star.

Противосияние The Gegenschein

If you look carefully enough, you can even see the glow of the Sun in the opposite direction. At night this glow is known as the gegenschein (German for "counter glow"), and can be seen as a faint glow in an extremely dark sky, as pictured above.

NGC 1365: спиральная галактика с перемычкой NGC 1365: A Nearby Barred Spiral Galaxy

Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a bar, but perhaps not so prominent as the one in NGC 1365, shown above. The persistence and motion of the bar imply relatively massive spiral arms.

Нейтринный детектор в Садбери The Sudbury Neutrino Detector

Two thousand meters below the ground, a giant sphere has begun to detect nearly invisible particles. These particles, neutrinos, are extremely abundant in the universe but usually go right through just about everything.

PKS285-02: молодая планетарная туманность PKS285 02: A Young Planetary Nebula

How do planetary nebulae acquire their exquisite geometrical shapes? To investigate this, astronomers used the Hubble Space Telescope to image several young planetary nebulae. These nebulae are the outer envelopes of stars like our Sun that have recently been cast away to space, leaving behind a core fading to become a white dwarf.
