Explanation: In this colorful mosaic, filaments of gas and dust span some 9 degrees across central Cygnus, a nebula rich constellation along the northern Milky Way. A trio of nebulae with popular names highlights the beautiful skyscape - the Butterfly, the Crescent, and the Tulip. At left, the Butterfly Nebula (IC 1318), lies near bright star Gamma Cygni. The Butterfly's expansive, glowing, wing-shaped gas clouds are divided by a dark dust lane. Near center, the Crescent Nebula (NGC 6888) is more compact, a cosmic bubble with a bright edge blown by winds from a massive Wolf-Rayet star. On the right is the Tulip Nebula (Sh2-101), a small emission region shaped like a blossoming flower viewed from the side. All are within a few thousand light-years of the Sun in the Orion spiral arm of our galaxy. The gorgeous mosaic is presented in false color, constructed from image data recorded through narrow band filters. The range of colors was created by a mapping of emission from hydrogen, sulfur and oxygen atoms in the nebula to red, green, and blue hues.

Новый снимок, сделанный спутником Aqua, демонстрирует довольно большое количество очагов возгораний, зафиксированных в северо-западной части Индии. Ну а шлейф от пожарищ растянулся на сотни километров. | | |

Explanation: What if you're driving down the street and an object from space shoots across the sky right in front of you? Such was the case last week for many people in south central Canada. Specifically, an extremely bright fireball, presumably a desk-sized meteor from deep space, flashed across the sky just after sunset on 2008 November 20. The bright fireball was recorded on many images and movies, including the spectacular video shown above that was captured by a dashboard camera of a police cruiser in Edmonton, Alberta, Canada. Because at least two streaks appear to be visible, the falling object likely broke up into pieces as it fell deep into Earth's atmosphere. By triangulating fireball images from several simultaneously recorded sources, astronomers hope to find an approximate orbit from whence the object came, as well as the likely place(s) on Earth where large pieces would have impacted, were they to have survived reentry. In the best case scenario, pieces would be recovered from a known deep space comet or asteroid, giving humanity an unprecedented look at an ancient object that likely holds clues to the early years of our Earth and the Solar System.

Explanation: Grand spiral galaxies often seem to get all the glory, flaunting their young, bright, blue star clusters in beautiful, symmetric spiral arms. But small, irregular galaxies form stars too. In fact, as pictured here, dwarf galaxy NGC 1569 is apparently undergoing a burst of star forming activity, thought to have begun over 25 million years ago. The resulting turbulent environment is fed by supernova explosions as the cosmic detonations spew out material and trigger further star formation. Two massive star clusters - youthful counterparts to globular star clusters in our own spiral Milky Way galaxy - are seen left of center in the gorgeous Hubble Space Telescope image. The above picture spans about 8,000 light-years across NGC 1569. A mere 11 million light-years distant, this relatively close starburst galaxy offers astronomers an excellent opportunity to study stellar populations in rapidly evolving galaxies. NGC 1569 lies in the long-necked constellation Camelopardalis.

| Кадр дня: In the Heart of the Tarantula Nebula » Нажмите, для открытия спойлера | Press to open the spoiler «

Explanation: In the heart of monstrous Tarantula Nebula lies huge bubbles of energetic gas, long filaments of dark dust, and unusually massive stars. In the center of this heart, is a knot of stars so dense that it was once thought to be a single star. This star cluster, labeled as R136 or NGC 2070, is visible just above the center of the above image and home to a great number of hot young stars. The energetic light from these stars continually ionizes nebula gas, while their energetic particle wind blows bubbles and defines intricate filaments. The above representative-color picture of this great LMC nebula details its tumultuous center. The Tarantula Nebula, also known as the 30 Doradus nebula, is one of the largest star-formation regions known, and has been creating unusually strong episodes of star formation every few million years.

Explanation: It may look like a grazing seahorse, but the dark object toward the image right is actually a pillar of smoky dust about 20 light years long. The curiously-shaped dust structure occurs in our neighboring Large Magellanic Cloud, in a star forming region very near the expansive Tarantula Nebula. The energetic nebula is creating a star cluster, NGC 2074, whose center is visible just off the top of the image in the direction of the neck of the seahorse. The representative color image was taken last year by the Hubble Space Telescope's Wide Field Planetary Camera 2 in honor of Hubble's 100,000th trip around the Earth. As young stars in the cluster form, their light and winds will slowly erode the dust pillars away over the next million years.
