Кассини пересекает плоскость колец Сатурна Movie: Cassini Crosses Saturns Ring Plane

What would the rings of Saturn look like if you passed right through the ring plane? To find out, NASA aimed cameras from the Cassini spacecraft right at Saturn's rings as the robotic explorer passed from the sunlit side of the rings to the shadowed side.

Шлем Тора: вид в телескоп CFHT Thors Helmet from CFHT

NGC 2359 is a striking emission nebula with an impressive popular name - Thor's Helmet Sure, its suggestive winged appearance might lead some to refer to it as the "duck nebula", but if you were a nebula which name would you choose?

Зеленый луч над Италией Movie: A Green Flash Over Italy

How could the Sun turn green? Difficult to observe, the momentary green flash above the rising or setting sun has been documented as a phenomenon caused by the atmospheric bending or refraction of sunlight.

Гиперион: спутник Сатурна со странными кратерами Saturn's 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 in late 2005 and took an image of unprecedented detail.

Замок и небо Castle and Sky

While Comet McNaught ruled southern skies, last week's conjunction of the Moon and Venus could be enjoyed by denizens of both hemispheres of planet Earth. The two more commonly viewed celestial beacons produced this lovely twilight scene, recorded last Saturday in skies above Almodovar near Cordoba in southern Spain.

Звездные скопления в NGC 1313 The Star Clusters of NGC 1313

Like grains of sand on a cosmic beach, individual stars of barred spiral galaxy NGC 1313 are resolved in this sharp composite from the Hubble Space Telescope's Advanced Camera for Surveys (ACS). The inner region of the galaxy is pictured, spanning about 10,000 light-years.

Колыбель в Орионе Orion s Cradle

Cradled in glowing hydrogen, stellar nurseries in Orion lie at the edge of a giant molecular cloud some 1,500 light-years away. This breath-taking view spans about 13 degrees across the center of the well-known constellation with the Great Orion Nebula, the closest large star forming region, just right of center.

Хвост кометы над горизонтом A Comet Tail Horizon

What's happening over the horizon? Many a sky enthusiast who thought they had seen it all had never seen anything like this. To the surprise of many Northern Hemisphere observers, the tail of Comet McNaught remained visible even after the comet's head set ahead of the Sun.

Млечный Путь над Параналом The Milky Way Over Paranal

It's not the sky that's falling. More accurately, the Earth is rising. The Earth's rotation gives a continually changing view to all Earth observers, including those measuring the universe at the Paranal Observatory.

Великолепный хвост кометы МакНота The Magnificent Tail of Comet McNaught

Comet McNaught, the Great Comet of 2007, has grown a long and filamentary tail. The spectacular tail spreads across the sky and is visible to Southern Hemisphere observers just after sunset. The head of the comet remains quite bright and easily visible to even city observers without any optical aide.
