Astronomy Picture Of the Day (APOD)

Рывок летающей космической камеры Sprint the Flying Space Camera
9.12.1997

Yes, but can your soccer ball do this? The ball near the middle of the above photograph is actually a robotic camera designed to float about a Space Shuttle and the International Space Station and take pictures.


Загадочные структуры на Ганимеде Mysterious Features on Ganymede
8.12.1997

Where is the rest of the circle? Jupiter's largest moon Ganymede has some truly unusual terrain, including the pictured half circle above cut by nearly parallel curves. Full circles can be easily explained by impact craters, but partial circles imply that some resurfacing has occurred since the original impact.


Трехраздельная туманность в красном, белом и голубом свете The Trifid Nebula in Red, White and Blue
7.12.1997

Three dark dust lanes give the picturesque Trifid Nebula its name. The red and blue colors of the Trifid Nebula are present in different regions and are created by different processes. A big bright star near the center of the red region appears white hot and emits light so energetic


Далекое скопление галактик A Distant Cluster of Galaxies
6.12.1997

In this 1994 Hubble Space Telescope photograph, every bright object is a galaxy. Oddly - most of them are spiral galaxies. This rich cluster of galaxies, named CL 0939+4713, is almost half way across the visible universe.


Галерея квазаров A Quasar Portrait Gallery
5.12.1997

QUASARs (QUASi-stellAR objects) lie near the edge of the observable Universe. Discovered in 1963, astronomers were astounded that such objects could be visible across billions of light-years, as this implies they must emit prodigious amounts of energy. Where does the energy come from?


Смотря через галактики Seeing Through Galaxies
4.12.1997

In this dramatic picture, spiral galaxy NGC 5091 appears in the foreground. Tilted nearly edge-on, the dust lanes between its spiral arms are clearly visible. The large elliptical galaxy NGC 5090 lies just beyond it - both are about 100 million light years distant in the southern constellation Centaurus. Can you see through the spiral galaxy?


Небо, полное планет A Sky Full Of Planets
3.12.1997

Look up tonight. Just after sunset, the crescent moon and all five "naked-eye" planets (Mercury, Venus, Mars, Jupiter, and Saturn) will be visible (depending on your latitude), lying near our solar system's ecliptic plane.


Убегающая звезда Runaway Star
2.12.1997

Runaway stars are massive stars traveling rapidly through interstellar space. Like a ship plowing through the interstellar medium, runaway star HD 77581 has produced this graceful arcing bow wave or "bow shock" - compressing the gaseous material in its path.


Микроквазар GRS1915 раздувается Micro-Quasar GRS1915 Puffs
1.12.1997

On the far side of our Galaxy, gas clouds explode away from a small black hole. This might seem peculiar, as black holes are supposed to attract matter. But material falling toward a black hole collides and heats up, creating an environment similar to a quasar that is far from stable.


Орион: большая картина Orion: The Big Picture
30.11.1997

Orion is big. Some of the stars that form the constellation of Orion are part of a giant gas cloud complex that stretches over 100 light years and appears more than 50 times the diameter of the Moon.
