Best space pictures for April 2012
The Eagle Nebula from Kitt Peak
This name this nebula received not by accident - from a distance it looks like an eagle. The approximate and detailed study of the Eagle Nebula, you can see that her light part - it is like a window into the interior of a huge dark cloud of dust. Through this window can be seen illuminated by the working part, which is the formation of scattered star cluster. This void in those places where the stars just beginning to be formed, remain high columns and round balls dark dust and cold molecular gas. In the center one can see already some bright young blue stars, radiation and stellar winds that burn and fanning fiber remaining gas and dust cocoon walls. Eagle emission nebula lies about 6,500 light-years away and is recorded in the directory under the M16 number.
dust devils on Mars
Due to the HiRISE camera, which is located on board the Mars Reconnaissance Orbiter, Mars late spring local resident was found in the northern hemisphere of the planet. This swirling dusty the Devil has a core whose diameter is about 30 meters, it travels along the smooth covered with dust, the plain Amazonis Plantitia towards the south-east. Devil raises dust pillar in the rarefied Martian atmosphere, which extends to a height of 800 meters above the surface. However, the dust column does not show the true, the real way to dust devils, as it blows east of the western breeze.
The evaporating droplets in the Carina Nebula
The Carina Nebula unusual droplets were found, which can be termed as "volatile." Many of them are floating in the direction of the image of the upper right corner. These droplets become opaque due to the fact that high-energy radiation and stellar winds nearby stars destroy the dark dust grains of sand. However, the fate of these is that such unusual droplets or dark molecular clouds often form inside the very stars, which lead to their destruction.
Area of star formation NGC 2264
At a distance of 2700 light years from us is this rather confused bunch of gas and dust. Powerful radiation just born stars provokes mixing reddish emission nebulae and dark interstellar dust clouds. We can observe the reflection nebulae, t. To. The light-absorbing dust clouds are in close proximity to the hot, young stars, and they reflect the light of the stars. Overview of the picture - about 3/4 of a degree, when compared with the size of the moon, it will be half its diameter. At a distance of star-forming region NGC 2264, it spans 40 light-years.
above Meteor Crater Lake
On a dark and moonless sky could be seen up to 30 meteors per hour, thanks Lyrids meteor shower, which recently reached its maximum size. One of the brightest meteors of stream Lyrids was left an unusual trace of the beautiful Crater Lake in Oregon, USA. It can be seen in this picture, which was created from nine photos.
M57: The Ring Nebula
The most famous celestial ring after ring of Saturn -tumannost M57. With our planet - the planet Earth - we look at the top of the cylinder-like cloud of glowing gas. This explains its classical form: the planet Earth and the rings have a mutual arrangement. However, in this spectacular composite image, which is obtained by means of the Hubble Space Telescope and ground telescope Subaru narrowband filters, far beyond the boundaries of the central region known nebula ring can consider wide looped structure. Naturally, this type of well-studied planetary nebula has absolutely nothing to do with planets. Glowing gas cover - is the upper layers that are thrown away from the dying stars like our Sun, located in the center of the nebula.
Dangerous sunrise on Gliese 876D
The danger in itself can carry sunrises on the planet Gliese 876d. Although, in fact, none of mankind does not know the actual conditions on the planet. It rotates at a very close distance from the star of the variable - a red dwarf star Gliese 876. This image shows how they imagined the artist. The mass of this planet is several times the mass of the Earth, and its orbit size smaller than the orbit of Mercury. Gliese 876d rotates so slowly that conditions on the planet day and night are very different. You can avoid the assumption that Gliese 876d can be a strong volcanic activity, caused by gravitational tides that deformiruyuet and warms the planet, and she is amplified in the daytime.
The sand dunes on Mars
At first glance, it seems that in this picture the fluid flows through the surface of Mars. However, in the rarefied atmosphere Mars liquids evaporate quickly freeze and nevertheless winds that blow continually create huge sand dunes similar to current jet and falling liquid droplets. In this image, the southern regions of Mars, made in the late spring - early summer, to the right shows two table mountains with flat tops. In the left part of the image can be seen with a light hill top. Winds blowing from right to left, as it were forced to flow around sand hills, forming a scenic trail.
Three auxiliary telescope
This photograph shows the tower, which are 1.8-meter auxiliary telescopes of Paranal Observatory in the Atacama Desert in Chile. These additional telescopes are designed for interferometry - a method to achieve exceptional accuracy and high resolution in observations along with an 8-meter telescopes of the observatory huge. In Paranal all four auxiliary telescopes operate, each of which is equipped with a conveyor. This conveyor moves the function executes and moves the telescope in the ways, making a variety of system configuration with these huge devices.

Northern Lights over Raufarhofnom
High in the sky, even without the colorful northern lights in this image are all lined up in one line. Not so long ago built "Arctic Henge" in Raufarhofne in the north of Iceland recorded in this picture. You can mentally continue the line that connects the top monuments, and see that it shows the direction to the north. Prove your assumptions is quite simple: in the picture is very clearly seen that the line passes through the two end stars of the Big Dipper - Merak and Dubhe, and then - to the bright North Star, which is the exact spot where the north end of the Earth's rotation axis is projected onto the celestial sphere.
