Деймос: маленький спутник Марса Deimos: A Small Martian Moon

Mars has two tiny moons, Phobos and Deimos. Pictured above is Deimos, the smaller moon of Mars. In fact, Deimos is one of the smallest known moons in the Solar System measuring only 9 miles across.

Скольжение Сервейора Surveyor Slides

"Safe!" In September 1967 (during regular season play), the Surveyor 5 lander actually slid several feet while making a successful soft landing on the Moon's Mare Tranquillitatis. Equipped with television cameras and soil...

Файер-болл Леонид 1966 года A Leonid Fireball From 1966

This bright fireball meteor was photographed from Table Mountain Observatory during the peak of the annual Leonid meteor shower on November 17, 1966. That was a good year for Leonid meteor watchers - a meteor "storm" was produced as the Earth swept through a dense swarm of dusty debris from the tail of comet Tempel-Tuttle.

Модель гамма-неба с помощью GLAST GLAST Gamma Ray Sky Simulation

This simulated image models the intensities of gamma rays with over 40 million times the energy of visible light, and represents how the sky might appear to the proposed Gamma-ray Large Area Space Telescope (GLAST) after its first year in orbit.

Над нами полярные сияния Aurora Above

On some nights the sky is the most interesting show in town. This picture captures a particularly active and colorful display of aurora that occurred a month ago high above Alaska. Auroras are more commonly seen by observers located near the Earth's poles.

NGC 3132: туманность Восьмерка NGC 3132: The Eight Burst Nebula

It's the dim star, not the bright one, near the center of NGC 3132 that created this odd but beautiful planetary nebula. Nicknamed the Eight-Burst Nebula and the Southern Ring Nebula, the glowing gas originated in the outer layers of a star like our Sun.

WR124: горящий звездый шар WR124: Stellar Fireball

Some stars explode in slow motion. Rare, massive Wolf-Rayet stars are so tumultuous and hot they are disintegrating right before our telescopes. Glowing gas globs each over 30 times more massive than the Earth are being expelled by a violent stellar wind.

Метеорный поток Леонид на следующей неделе Leonid Meteor Shower Next Week

Early next week, a spectacular meteor storm is expected: the 1998 Leonids. It is widely thought that that the meteors from the Leonids meteor shower are just small pieces of Comet Temple-Tuttle falling to Earth.

Шаровое скопление 47 Тукана Globular Cluster 47 Tucanae

Stars come in bunches. Of the over 200 globular star clusters that orbit the center of our Milky Way Galaxy, 47 Tucanae is the second brightest globular cluster (behind Omega Centauri). Known to some affectionately as 47 Tuc or NGC 104, it is only visible from the Southern

Каллисто в разрезе: Лед, Камни и Океан Cutaway Callisto: Ice, Rock, and Ocean

Cruising past the moons of reigning gas giant Jupiter, Voyager and Galileo have returned tantalizing evidence for a liquid water ocean beneath the surface of Europa. Now researchers are reporting telltale indications that the battered Jovian moon Callisto may also harbor a subsurface
