Astronomy Picture Of the Day (APOD)

Соседняя карликовая галактика Лев-I Nearby Dwarf Galaxy Leo I

Leo I is a dwarf spheroidal galaxy in the Local Group of galaxies dominated by our Milky Way Galaxy and M31. Leo I is thought to be the most distant of the eleven known small satellite galaxies orbiting our Milky Way Galaxy.

Солнце сегодня The Sun Today

Our Sun shows a different face every day. The above picture was taken on May 15, but a similar picture of the Sun actually taken today can be found here. The above picture was taken in red light and so is shown in red.

Комета Хиякутаке и солнечная вспышка Comet Hyakutake and a Solar Flare

A rare coincidence was recently captured by the orbiting SOHO spacecraft. During the closest approach to the Sun of Comet Hyakutake on May 1, SOHO photographed the comet. By accident -- during the time this photograph was being taken -- a solar flare was being ejected from the Sun.

Комета Хиякутаке проходит по Солнцу Comet Hyakutake Passes the Sun

On May 1, Comet Hyakutake made its closest approach to the Sun. During this time it was not possible to view the comet with most astronomical instruments because of the brightness of the nearby Sun.

Млечный Путь вблизи Северного Креста The Milky Way Near the Northern Cross

This beautiful image of the sky near the bright star Deneb (just above center) reveals the stars, nebulae, and dark clouds along the plane of our Milky Way Galaxy as seen from the northern hemisphere (near Columbia Missouri, USA). Just below Deneb lies the suggestively shaped North American emission nebula.

Постоянная Хаббла и расширение Вселенной (II) Hubble's Constant And The Expanding Universe (II)

In this century, the discovery that the Universe is expanding has produced a revolution in human thought about the Cosmos. American astronomer Edwin Hubble played a major role in this profound discovery, coining the "Hubble constant".

Постоянная Хаббла и расширение Вселенной (I) Hubble's Constant And The Expanding Universe (I)

Our Universe is expanding. Distant galaxies appear to recede from us at ever-increasing speeds. What is the rate of expansion? How long has it been expanding? What will be its ultimate fate? Two groups of astronomers are searching vigorously for answers to these fundamental questions using the Hubble Space Telescope (HST).

Слежение за спутниками Сатурна Tracking Saturn's Moons

These five pairs of Hubble Space Telescope images track some of Saturn's moons as they orbit the ringed planet. A pair of images was taken every 97 minutes on November 21, 1995 with the Wide Field Planetary Camera-2, the normally bright ring system appearing nearly edge-on.

Просвечивание солнечного света через кольца Сатурна Sunlight Through Saturn's Rings

Normally, Earth based astronomers view Saturn's spectacular ring system fully illuminated by reflected sunlight. However, this November 1995 Hubble Space Telescope composite image was made to take advantage of an unusual perspective, with the Sun actually illuminating the rings from below.

Хенице 70: очень большой пузырь в Большом Магеллановом Облаке Henize 70: A SuperBubble In The LMC

Massive stars (tens of times the mass of the Sun) profoundly affect their galactic environment. Churning and mixing the clouds of gas and dust between the stars, they leave their mark in the compositions and locations of future generations of stars and star systems.
