Галактические войны: M81 против M82 Galaxy Wars: M81 Versus M82

In the left corner, wearing a red nucleus surrounded by blue spiral arms, is M81. In the right corner, sporting light stars and dark dust lanes, is M82. These two mammoth galaxies have been locked in gravitational combat for the past billion years.

Кольца около β Живописца Rings Around Beta Pictoris

An unusual dust disk surrounds nearby star Beta Pictoris. Discovered in 1983, astronomers are still learning just how unusual this disk is. Recent images and computer simulations indicate that the disk contains several elliptical dust rings larger than our own Solar System.

Дымоход W4 The W4 Chimney

A huge chimney venting hot clouds of gas out from the plane of our Milky Way Galaxy has recently been imaged in radio waves. The Canadian Galactic Plane Survey team used an array of radio telescopes to survey an ionized gas region known as W4.

Таинственные кольца сверхновой 1987A The Mysterious Rings of Supernova 1987A

What's causing those odd rings in supernova 1987A? In 1987, the brightest supernova in recent history occurred in the Large Magellanic Clouds. At the center of the picture is an object central to the remains of the violent stellar explosion.

NEAR и астероид Эрос NEAR to Asteroid Eros

On December 23, 1998 the Near Earth Asteroid Rendezvous (NEAR) spacecraft flew by asteroid 433 Eros. The robotic spacecraft was intended to brake and orbit Eros, but an unexpected shutdown of its main engine caused this plan to be aborted.

Рентгеновские звезды Ориона X-Ray Stars Of Orion

The stars of Orion shine brightly in northern winter skies where the constellation harbors the closest large stellar nursery, the Great Nebula of Orion, a mere 1500 light-years away. In fact, the apparently bright...

Цветастые облака Киля Colorful Clouds Of Carina

Tumultuous clouds of the Carina Nebula, 8000 light-years away, glow in planet Earth's southern sky. Striking and detailed, this close-up of a portion of the famous nebula is a combination of exposures through six different filters taken with the Hubble Space Telescope's Wide Field Planetary Camera 2 in April of 1999.

Эоловый Марс Aeolian Mars

Mars' atmosphere is relatively thin, still when martian winds blow they weather and shape its surface. Like familiar aeolian features on Earth, this field of dunes within Mars' Rabe crater exhibits graceful undulating ridges which can shift as windblown material is deposited on the dunes' windward face and falls away down the steeper leeward slopes.

Скопление галактик Abell 2218: линзы Abell 2218: A Galaxy Cluster Lens

Gravity can bend light. Almost all of the bright objects in this recently released Hubble Space Telescope image are galaxies in the cluster known as Abell 2218. The cluster is so massive and so compact that its gravity bends and focuses the light from galaxies that lie behind it.

Снежный шторм на Земле Snowstorm on Planet Earth

Earth is an ocean planet. From low Earth orbit, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) instrument onboard NASA's SeaStar spacecraft globally maps ocean color, tracking changes in the climate and biosphere of our water world.
