Astronomy Picture of the Day

Astronomy Picture Of the Day (APOD)

Частное затмение, облачный день Partial Eclipse, Cloudy Day

Welcome to the December Solstice, first day of winter in the north and summer in the southern hemisphere of planet Earth. Today the Sun reaches its southernmost declination in the sky at 19:21 Universal Time.

Па-де-де Юпитера и Сатурна Jupiter and Saturn Pas de Deux

Viewed from Earth, the solar system's planets do a cosmic dance that is hard to appreciate on any single night. But consider this well planned animated sequence combining 23 pictures taken at approximately 2 week intervals from June 2000 through May 2001.

Поиски темной материи Finding Dark Matter

Where is dark matter? Galaxies rotate and move in clusters as if a tremendous amount of unseen matter is present. But does dark matter exist in the greater universe too -- and if so, where? The answer can be found by comparing the distribution of galaxies observed with numerical simulations.

Шарплесс 212: излучение водорода и серы Sharpless 212 in Hydrogen and Sulfur

Where do the most massive stars form? Observational evidence indicates that the outskirts of developing open clusters of stars are primary locations. Pictured above is one such open cluster: Sharpless 212. Visible in the image center are massive stars in the open cluster.

Покидая Международную космическую Станцию Leaving the International Space Station

It was time to go home. During their eight days aboard the Earth-orbiting International Space Station (ISS), ESA Flight Engineer Claudie Haigner, Russian Commander Victor Afanasyev, and Russian Flight Engineer Konstantin Kozeev had completed several experiments and successfully delivered a new lifeboat.

Туманность Конская Голова The Horsehead Nebula

One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s.

Ганимед: распавшаяся комета — цепочка кратеров Ganymede: Torn Comet Crater Chain

This striking line of 13 closely spaced craters on Jupiter's moon Ganymede was photographed by the Galileo spacecraft in 1997. The picture covers an area about 120 miles wide and the chain of craters cuts across a sharp boundary between dark and light terrain. What caused this crater chain?

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.

Южный полюс Марса The South Pole of Mars

The south pole of Mars is the bright area near the center of the detailed, subtly shaded color image above. Recorded in September of this year by the Mars Global Surveyor (MGS) spacecraft, the picture shows a region surrounding the 400 kilometer wide martian polar cap in the midst of southern hemisphere spring.

Леониды над Корейской обсерваторией Leonids Over Korean Observatory

There were two peaks to this year's Leonid Meteor Shower. The first peak was best seen during the early morning hours of November 18 in North America, while the second peak, almost twice the intensity of the first, occurred eight hours later and was best seen from Asia.
