Astronomy Picture Of the Day (APOD)

Пульсар и движение газа в Крабовидной туманности The Crab Nebula Pulsar Shrugs

How does a city-sized neutron star power the vast Crab Nebula? The expulsion of wisps of hot gas at high speeds appears to be at least part of the answer. Yesterday time-lapse movies taken...

Астероид 1998 KY26 Asteroid 1998 KY26

A day is just under 11 minutes long on 1998 KY26, a 30 meter wide, fast-spinning, water-rich asteroid. This computer simulated view of its lumpy surface has a resolution of about 3 meters and is based on radar and optical observations (click on the image for a series of surface views).

Вид звездного неба в Стрельце APOD: 2002 September 18- A Sagittarius Starscape

Many vast star fields in the plane of our Milky Way Galaxy are rich in clouds of stars, dust, and gas. First and foremost, visible in the above picture are millions of stars, many of which are similar to our Sun.

Сила из пустого пространства: эффект Казимира A Force from Empty Space: The Casimir Effect

This tiny ball provides evidence that the universe will expand forever. Measuring slightly over one tenth of a millimeter, the ball moves toward a smooth plate in response to energy fluctuations in the vacuum of empty space.

Подготовка к запуску ракеты Атлас V An Atlas V Rocket Prepares to Launch

The first launch of an Atlas V rocket occurred last month. The Atlas V, built by Lockheed Martin, is the first rocket in the U. S. Air Force's Evolved Expendable Launch Vehicle program. Rockets in this program can carry increasingly heavy payloads by just adding more boosters.

Зодиакальный свет и ложный рассвет Zodiacal Light and the False Dawn

An unusual triangle of light will be particularly bright near the eastern horizon before sunrise during the next two months for observers in Earth's northern hemisphere. Once considered a false dawn, this triangle of light is actually Zodiacal Light, light reflected from interplanetary dust particles.

Луна в рентгеновских лучах X Ray Moon

This x-ray image of the Moon was made by the orbiting ROSAT (Röntgensatellit) Observatory in 1990. In this digital picture, pixel brightness corresponds to x-ray intensity. Consider the image in three parts: the bright hemisphere of the x-ray moon, the darker half of the moon, and the x-ray sky background.

Плато Аристарх Aristarchus Plateau

Anchored in the vast lava flows of the Moon's Oceanus Procellarum lies the Aristarchus Plateau. Recorded from a backyard observatory on planet Earth, this sharp, amazingly colorful view nicely captures the geologically diverse area, including the brownish plateau, Aristarchus and Herodotus craters, and the meandering Vallis Schroteri.

Рентгеновское излучение остатка сверхновой Тихо X Rays From Tycho s Supernova Remnant

In 1572, Danish astronomer Tycho Brahe recorded the sudden appearance of a bright new star in the constellation Cassiopeia. The new star faded from view over a period of months and is believed to have been a supernova, one of the last stellar explosions seen in our Milky Way galaxy.

Затмение тройной звезды Плутоном и Хароном Pluto and Charon Eclipse a Triple Star

Occasionally, a planet in our Solar System will pass in front of a bright star. Since stars and planets take up so little space on the sky, such events are quite rare. Two months ago, however, Pluto and its large moon Charon passed in front of a comparatively bright triple star system known as P126.
