Hyperion: Saturn with strange craters

What is at the bottom of Hyperion strange craters? No one knows. To help find out, the robotic Cassini spacecraft currently orbiting Saturn accesses at the end of 2005 and in 2010 flew about Hyperion and received images of its surface with an exceptionally high resolution. In the image shown here in false-color, you can see the wonderful world of the satellite, similar to a sponge, unusual surface is covered with strange craters. Small differences of color, seems to reflect the differences in the chemical composition of the surface. At the bottom of most craters lies some unknown dark substance. The presence of light components in this image indicates that in some places the thickness of dark matter can be only a few tens of meters. Hyperion size - about 250 kilometers.

Galaxy Porpoise

What's wrong with this spiral galaxy? Only a few hundred million years ago, NGC 2936 (top of two large galaxies in the picture) was probably an ordinary spiral galaxy: it revolved, created the stars, in general, do their own thing. But once it is too close to a massive elliptical galaxy NGC in 2937 and lost its way. NGC 2936, known as the Galaxy Porpoise for its unusual shape, not just a twisted, she always strongly deformed due to strong gravitational interaction with a neighbor. Recently born blue stars shaped nose porpoise space, looking to the left, and the mid-helix looks like her eyes. A pair of galaxies together bearing the name of Arp 142, looks like a penguin protecting its egg. In any case, intricate dark dust and fiber tails their blue stars associated with the lower upper galaxy. This recently published photos showing the galaxy Arp 142 in unprecedented detail, was made the Hubble Space Telescope last year

of NGC 6302: The Butterfly Nebula

Not many butterflies are such a large wingspan. Bright clusters and nebulae in the night sky of the planet Earth are often given names by the names of plants and insects, and the nebula NGC 6302 is no exception. The central star of this planetary nebula extremely hot: surface temperature is about 250 thousand degrees Celsius. It shines in the ultraviolet range, but is hidden from direct observation of a dense torus of dust. It's surprisingly detailed image of the nebula surrounding a dying star has been obtained Space Telescope. Hubble shortly after its renovation in 2009. Dust ring surrounding the central star, crosses a bright cavity of ionized gas, and we can see almost exactly edge-on. Molecular hydrogen was detected in the dust outer shroud hot star. Nebula NGC 6302 lies about 4 million light-years away in the constellation Scorpius.

Halo super-moon

When the sun went last Sunday, he has risen full moon at perigee. She was the closest to the Earth, and therefore the brightest and largest full moon of this year, and it was called a super moon. Light super-moon has created a magnificent circular halo, which can be seen from Punta Piedras and the mouth of the river La Plata near Buenos Aires in Argentina. Size lunar halo determined by the geometry of the hexagonal ice crystals in high, thin clouds on the planet Earth. The crystals are strongly reflected moonlight beams at an angle of 22 degrees. Therefore, the inner radius of the halo - 22 degrees, it does not depend on the size of the moon the visible. Beautiful halo with a radius of 22 degrees can be seen at any time of year, much more than a super-moon.

Bands of dry ice on Mars

Why on Mars there were such long and almost straight grooves? They are formed on the slopes of some sand dunes during the Martian spring, they are called "linear gullies". The grooves have an almost constant width, their length is two kilometers, along their edges by shafts rising above ambient sand. Unlike most of the water streams, they do not form parts of a dry rock eroded at the end of the slopes. According to the most likely hypothesis has been tested in the world, linear ravines formed when the ice pieces of carbon dioxide (dry ice) break off and slide along the slope and sublimates into a gas and in the end completely evaporate into thin air. If so, in the future, adventurers will be able to ride on these natural "sledging" dry ice, sliding on an air cushion of the evaporating carbon dioxide

Full Moon at perigee

Big, bright, beautiful moon rise on Sunday, when the Sun will sit. The exact time of the full moon - June 23, 11:32 UT. It will happen just before the moon will pass the perigee - the closest point to the Earth in an orbit of the moon. Thus, it will be the biggest full moon of 2013. However, such circumstances are not very rare. The full moon occurs near the perigee of the lunar orbit in about 14 lunar months. This means that the next full moon at perigee occurs August 10, 2014, it will be the 14th full moon after 23 June. 5th May 2012, 14 lunar months ago, the full moon at perigee was captured rising above Cape Sounion and the ancient temple of Poseidon in Greece on this beautiful night scenery.

Area of ​​star formation NGC 3582

There are formed bright stars and causing a molecule of interest. Nebula with a complex structure is in the star-forming region called RCW 57. This image shows dense clumps of dark interstellar dust, bright stars that have formed over the past few million years, fields of glowing hydrogen gas ionized by these stars, and great loops of gas discharged dying stars. Last NGC 3582 detailed investigation has revealed at least 33 massive stars at the final stages of formation, and the apparent presence of complex carbon-containing molecules known as polycyclic aromatic hydrocarbons. It is assumed that these molecules are formed in the cooling gas in star-forming regions, and their appearance in the nebula from which five billion years ago formed the sun, could be an important step in the development of life on Earth.

Side view of the galaxy NGC 3628

Clear telescopic image of the galaxy NGC 3628 spiral gorgeous, we see the side show a galactic disk, crossed by dark dust lanes. This remarkable kind of reminds astronomers about its popular name - Galaxy Hamburger. The diameter of NGC 3628 - about 100 thousand light years and lies in the northern spring constellation Leo, at a distance of 35 million light-years.

Sharpless 115

Object Sharpless 115 lies a bit north-west of Deneb - the brightest star in the constellation Cygnus on planet Earth's sky. This cute, but slightly glowing nebula recorded in the catalog in 1959 the astronomer Stewart Sharpless under Sh2-115 number, lies about 7500 light-years away at the edge of a giant molecular cloud in the back of the Milky Way. Light nebula visible in this composite image in synthetic palette Hubble Space Telescope, create ionized hydrogen atoms, sulfur and oxygen. They are fueled by high-energy radiation of young stars in the cluster, Berkeley 90. This accumulation of probably about 100 million years, and it is still hiding inside the nebula Sharpless 115

Once the molten surface of Venus

If you look at Venus through the eyes of the radar, the following picture will appear in front of us. Figure Venus surface obtained by computer reconstruction based on the data interplanetary stations Magellan observations. Magellan station was in orbit around Venus in 1990-1994. Radar was used for mapping the surface of our neighboring planet. With Magellan's many interesting formations on the surface of the planet was found, in particular, those big round dome with a typical size of 25 km. The mechanism of their formation remains unclear. Perhaps the dome arose as a result of volcanic activity. The surface of Venus is so hot and hostile that the probe can work on it only a few minutes.

All Mercury

For the first time a map of the entire surface of the planet Mercury. Detailed observations amazing cortex closest to the Sun, the planet carried out since then, as the robotic spacecraft MESSENGER first flew past Mercury in 2008 and went on its orbit in 2011. Previously, most of the surface of Mercury has remained unexplored. The planet is too far away to ground-based telescopes were able to get a clear picture of her, and during the flight of Mariner 10 in the 1970s managed to otnablyudat only about half of the surface. The video was edited from thousands of images of Mercury, the colors of which have been strengthened in order to better distinguish the patterns on the surface. The film shows the rotation of the planet, and at first we see the beams formed after the incident in the north of the collision and stretching for the most part of the world. Around the middle of the film there is painted in bright colors Caloris basin - an ancient structure in the north, which arose after the collision, and then filled with lava. Messenger has already successfully completed the primary and the first expansion of the program.
