Astronomy Picture Of the Day (APOD)

Средневековая астрономия из аббатства Мельк Medieval Astronomy from Melk Abbey
17.04.2009

Discovered by accident, this manuscript page provides graphical insight to astronomy in medieval times, before the Renaissance and the influence of Nicolaus Copernicus, Tycho de Brahe, Johannes Kepler, and Galileo. The intriguing page...


Замок и полная Луна Castle and Full Moon
16.04.2009

Clouds couldn't hide this bright Full Moon as it rose last week over the medieval castle of Tourrette-Levens near Nice, France. Exactly full on April 9 at 1456 UT, it followed the March equinox, making it the first Full Moon of spring in the north and autumn in the southern hemisphere.


Зубчатые тени от частиц в кольце Сатурна? Jagged Shadows May Indicate Saturn Ring Particles
15.04.2009

What's causing unusual jagged shadows on Saturn's rings? No one is yet sure. As Saturn nears equinox, its rings increasingly show only their thin edge to the Earth and Sun. As a result, Saturn's moons now commonly cast long shadows onto the rings.


M101: галактика Вертушка M101: The Pinwheel Galaxy
14.04.2009

Why do many galaxies appear as spirals? A striking example is M101, shown above, whose relatively close distance of about 27 million light years allow it to be studied in some detail. Recent evidence...


M39: рассеянное скопление в Лебеде M39: Open Cluster in Cygnus
12.04.2009

Lying just at the limit of human perception is a picturesque starfield containing one of the larger open clusters on the northern sky. Spanning an angle larger than the Moon, M39's relatively few stars lie only about 800 light years distant toward the constellation of Cygnus.


Большая картина The Big Picture
11.04.2009

Intricate, glowing nebulae that shine in planet Earth's night sky are beautiful to look at in deep images made with telescopes and sensitive cameras. But they are faint and otherwise invisible to the naked-eye. That makes their relative location and extent on the sky difficult to appreciate.


МКС и астронавт ISS and Astronaut
10.04.2009

These two frames, taken with a video camera and a telescope, reveal remarkable details of the International Space Station (ISS) orbiting some 350 kilometers above planet Earth. Recorded during last month's visit...


Венера приближается к внутреннему соединению Venus Near Inferior Conjunction
9.04.2009

This remarkable picture of a slender crescent Venus was made during daylight hours on March 26. Venus was then very near inferior conjunction, its closest approach to a point on a line directly between Earth and the Sun.


Необычная запыленная галактика NGC 7049 Unusual Dusty Galaxy NGC 7049
8.04.2009

How was this unusual looking galaxy created? No one is sure, especially since spiral galaxy NGC 7049 looks so strange. NGC 7049's strikingly appearance is primarily due to an unusually prominent dust ring seen mostly in silhouette. The opaque ring is much darker than the din of millions of bright stars glowing behind it.


Сталкивающиеся спиральные галактики Арп 274 APOD: 2009 April 7 The Colliding Spiral Galaxies of Arp 274
7.04.2009

Two galaxies are squaring off in Virgo and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. This is because galaxies are mostly empty space and, however bright, stars only take up only a small fraction of that space.
