Группа галактик HCG 87 Galaxy Group HCG 87
31.07.2003

Posing for this cosmic family photo are the galaxies of HCG (Hickson Compact Group) 87, about four hundred million light-years distant toward the amphibious constellation Capricornus. The large edge-on spiral near picture center...


Ледяные горы на Марсе Frosty Mountains on Mars
30.07.2003

What causes the unusual white color on some Martian mountains? The answer can be guessed by noticing that the bright areas disappear as springtime takes hold in the south of Mars: dry ice. Unlike water ice, dry carbon dioxide ice sublimates directly to gas from its frozen state.


Бурление оранжевого Солнца Orange Sun Simmering
29.07.2003

Even a quiet Sun is a busy place. The above image, taken in a single color of light called Hydrogen Alpha, records a great amount of detail of the simmering surface of our parent star.


Запуск марсохода "Дух" Launch of the Spirit Rover Toward Mars
28.07.2003

Next stop: Mars. Last month the first of two missions to Mars was launched from Cape Canaveral, Florida, USA above a Boeing Delta II rocket. Pictured above, solid fuel boosters are seen falling away as light from residual exhaust is reflected by the soaring rocket.


Карлик в созвездии Водолея The Aquarius Dwarf
27.07.2003

Our Milky Way Galaxy is not alone. It is part of a gathering of about 50 galaxies known as the Local Group. Members include the Great Andromeda Galaxy (M31), M32, M33, the Large Magellanic Cloud, the Small Magellanic Cloud, Dwingeloo 1, several small irregular galaxies, and many dwarf elliptical and dwarf spheroidal galaxies.


Спиральная галактика NGC 7742 Spiral Galaxy NGC 7742
26.07.2003

This might resemble a fried egg you've had for breakfast, but it's actually much larger. In fact, ringed by blue-tinted star forming regions and faintly visible spiral arms, the yolk-yellow center of this face-on spiral galaxy, NGC 7742, is about 3,000 light-years across.


Гало вокруг туманности Гантель Dumbbell Nebula Halo
25.07.2003

In 1764, French astronomer Charles Messier sighted this gorgeous cosmic cloud which he described as an oval nebula without stars. Cataloged as M27, it is now popularly known as the Dumbbell Nebula...


Марс рядом с Луной Mars at the Moon s Edge
24.07.2003

What was that bright "star" near the Moon last week? Mars of course, as the Red Planet wandered near the wanning gibbous Moon early last Thursday morning, passing behind the lunar orb when viewed from some locations in South and Central America, the Carribean, and Florida.


Гравитационная карта Земли по данным GRACE GRACE Maps the Gravity of Earth
23.07.2003

Why do some places on Earth have higher gravity than others? Sometimes the reason is unknown. To help better understand the Earth's surface, slight distance changes between a pair of identically orbiting satellites named GRACE have been used to create the best ever map of Earth's gravitational field.


Торнадо на планете Земля A Tornado on Planet Earth
22.07.2003

Large storms on Earth can spawn unusual, small, violent clouds known as tornadoes. Tornado clouds swirl as fast as hundreds of kilometers per second and, when they touch down, can destroy nearly everything in their long, narrow path. Many tornadoes last only a few minutes, but the largest and most dangerous can endure for hours.
