Leo A: Близкая карликовая неправильная галактика Leo A: Nearby Dwarf Irregular Galaxy

Why isn't this small galaxy simple? The above image and contemporary observations of small nearby galaxy Leo A were supposed to show it has a simple structure. Now Leo A is known...

Все небо в многоцветной короне полярного сияния A Full Sky Multi Colored Auroral Corona

On some nights the sky is the most interesting show in town. This fisheye picture captures a particularly active and colorful auroral corona that occurred two days ago over l'Observatoire de la Decouverte in Val Belair near Quebec, Canada.

Юпитер и Венера на восходе Jupiter and Venus at Sunrise

What are those bright objects in the morning sky? Early morning dog walkers, among many others across our world's Northern Hemisphere, have likely noticed tremendously bright Venus hanging in the eastern sky just before sunrise. Looking a bit like an approaching airplane, Venus holds its place in the sky and never seems to land.

Центр Галактики в инфракрасном диапазоне The Galactic Center in Infrared

The center of our Galaxy is a busy place. In visible light, much of the Galactic Center is obscured by opaque dust. In infrared light, however, dust glows more and obscures less, allowing nearly one million stars to be recorded in the above photograph.

Рентгеновское излучение из галактического центра X-Rays from the Galactic Core

Using the orbiting Chandra X-ray Observatory, astronomers have taken this long look at the core of our Milky Way galaxy, some 26,000 light-years away. The spectacular false-color view spans about 130 light-years.

Остаток сверхновой в гамма-лучах Supernova Remnant Imaged in Gamma Rays

Gamma rays are the most energetic form of light. With up to a billion times the energy of ordinary "medical" x-rays, they easily penetrate telescope lenses and mirrors, making it very difficult to create gamma-ray images of cosmic sources.

NGC 7024: Туманность Ирис NGC 7023: The Iris Nebula

Like delicate cosmic petals, these clouds of interstellar dust and gas have blossomed 1,300 light-years away in the fertile star fields of the constellation Cepheus. Sometimes called the Iris Nebula and dutifully cataloged as NGC 7023, this is not the only nebula in the sky to evoke the imagery of flowers.

Как проходило лунное затмение A Time Lapse Lunar Eclipse

During last week's lunar eclipse, our Moon appeared to disappear. As the Earth moved between the Moon and the Sun, the Earth's shadow fell on the moon, making it quite dark.

"Аллея бурь" на Сатурне Storm Alley on Saturn

What causes storms on Saturn? To help find out, scientists commanded the robot Cassini spacecraft now orbiting Saturn to inspect a circulating band of clouds nicknamed "Storm Alley." This westwardly moving cloud ring...

Похожая на привидение область звездообразования DR 6 Spooky Star Forming Region DR 6

How could stars form such a spooky and familiar shape as a human skull? First, the complex process of star formation creates nebulas of many shapes and sizes -- it is human perception that identifies the skull shape.
