The 'super-Earths', with a mass 10 times greater than Earth's, are good candidates to find life outside our solar system.
Located 42 light years away, GJ 1214b is one of the most studied because it can be seen from ground-based telescopes with relative ease
The data obtained with the GTC by IAC researchers support the idea that GJ1214b's atmosphere is made up of metal.

Many of the population of the Earth are often not even aware that beyond the Earth, on the surface of other planets - and not only, by the way, the planets - the solar system sometimes furious incredible storms.
Over the past decade, the spacecraft was a lot of pictures of the amazing extraterrestrial phenomena on the scale exceeding everything that we can watch on their home planet.
Last July, the crack of dawn probe entered orbit around the asteroid Vesta, the second largest asteroid main asteroid belt located between the orbits of Mars and Jupiter. To date, Dawn helped create 3-D map more than 80 percent of the surface of Vesta.
The most interesting thing that we found out with the machine Dawn, - is that the news is the core of nickel and iron, such as the core of Mercury, Earth and Mars.
In Shanghai's Dongxiang district, on the territory of the Chinese Academy of Sciences, built the largest fully steerable radio telescope in Asia. This plant, with a diameter of 65 meters, is the fourth largest in the world.
Usually, projects of this magnitude take 8 to 10 years, but the Chinese have always been known for the fact that they can work quickly.
Using the Sloan Digital Sky Survey, the researchers found that the torrent of stars, which is supposed to symbolize the remains of ancient star clusters, slowly absorbed with you our own Milky Way galaxy.
A team of astronomers from Yale University led by Ana Bonaca, masters and lead author of the new study, had previously noted that the Milky Way has a tendency to absorb dwarf galaxies,
Scientists have found evidence of what may be the fastest moving pulsar. During the observation using three different telescopes - NASA's X-ray Observatory "Chandra", ESA XMM-Newton, located in space, and a radio telescope Parks in Australia.
X-ray observations, "Chandra" and XMM-Newton were combined with infrared data of the project 2MASS optical data and digital images of the sky.

Located only at a distance of 25 light years from Earth, Fomalhaut is a fairly young star, twice as massive as our sun, and discovered in 1980 in a large amount of dust.
Now, astronomers using a telescope Herschel discovered a dense strip of dusty materials, about half of which is water ice at the edges of the system.
An international team of astronomers has created a directory enclose more than 84 million stars in the Milky Way. The basis for this proposal is a huge picture of the size of nine gigapixel, which amounted to an infrared VISTA telescope data Chilean observatory.
Image of stars the size is nine meters long and seven meters wide.
Roberto Saito, the lead researcher of the Pontifical Catholic University of Chile considers that this work will help to better understand the formation and evolution of spiral galaxies.

NASA's Cassini spacecraft recorded the effects of an ancient giant storm on Saturn. New data pointed to record conflict in the upper atmosphere of the planet, which existed for a long time after the in evidence signs of the storm had disappeared, and that the storm was actually much stronger than previously thought.
In the analysis of data obtained from the composite infrared spectrometer apparatus Cassini, discovered that a powerful electrical discharges that occurred during the storm, Saturn's stratosphere warmed to 83 Kelvin above its normal temperature.
Huge extrasolar planet, which many astronomers thought the "dead and buried", came back to life, researchers say.
A new study of the results of observations made space telescope "Hubble", found lying around nearby star Fomalhaut us really exists giant exoplanet, which scientists dubbed exoplanets, "zombies." These findings oppose the results of other recent studies claiming that the so-called "planet" - known as Fomalhaut b - is actually a huge cloud of dust.
Who of us do not ever remember the Old New Year with a sad joy, and now we have a new oxymoron - a mini-supermassive black hole (BH). However, regardless of the fact that this black hole is the tiny class of super-massive black hole, its mass is still huge - it is about 200,000 mass of our Sun.
A team of astronomers led by Nathan Sekrestom of George Mason University, explore the galaxy NGC 4178, did not expect that at the center of this galaxy is the black hole, as NGC 4178 has pronounced bulge - bright area near the center of the galaxy,
Damian Peach is the most accepted and planetary astrophotography while most "hated" the world. Admired by the incredible images it achieves. Hated because, although some approaches you, no one can its level. And it is very secretive and does not share their methods.
There is much speculation about how it does. Legend has it that gives access Celestron factory and can thus choose the best SC.
The attractive emanation nebula NGC 6164 was created by a strange, hot and bright star of type O , about 40 times more massive than the Sun Vista here in the center of the cosmic cloud, the star has an age of 3-4000000 years, within three or four million years will end its life in a supernova explosion .
With a diameter of about 4 light years away, the nebula has a bipolar symmetry,

The origin of most galaxies is not uniform, but run in several stages. This is a study of over 900 globular clusters by an international research team. The star clusters from the dawn of galaxy formation to occur mostly in two different chemical variants, the astronomers reported in the journal "Monthly Notices of the Royal Astronomical Society".
"This indicates presence of two types of globular clusters suggest that most large galaxies have gone through two phases of star formation through", Christopher Usher of the Swinburne University of Technology in Australia write Hawthorn and his colleagues.
A thick tome on the sun, I thought, as I chosen up the package from the post, and in fact, it is a book that is all about the sun, turning the central star of our solar system. It is inconsistently the most misunderstood today star we know and the reference star is still for many astronomical state variables such as mass or luminosity.
If you expect good information about them - it's really about time that once again a book on the current results and findings of solar research is published - will be disappointed by the book,
The northern Milky Way in the area over cipher Cassiopeia to Peruses is rich in interstellar matter. There are not only bright H II regions, but also reflection nebula and a lot of dark dust and molecular clouds. The current Academy of Sciences demonstrates a very nice example of a combination of molecular cloud and reflection nebula, namely, a brownish, elongated cloud in the border area Andromeda and Cassiopeia.
So far, they escape despite kilometer-scale detector systems of discovery: gravitational waves, vibrations of space-time whose survival Einstein forecast in his theory of general relativity. However, the detection of gravitational waves could soon be possible. And not with special detectors, but with ordinary radio telescopes that measure the arrival time of the radio signals from pulsars. The vibrations are there but not - as has been mostly assumed - as a sort of background noise, but it dominate individual signals of individual sources.

See the sights distant quasar J1148 +5251, scientists have discovered around stars, although it was unspecified that in order to achieve its massive group of three billion solar masses of quasar need to consume large quantities of stars in each year for several hundred million years.
The answer has not yet been found, but after observing in the near infrared wide-angle camera number three NASA space telescope "Hubble", the scientists were able to put forward the assumption about the nature of the mysterious disappearance of the stars of the galaxy surrounding the quasar.
Powerful flare blow up on the Sun on Monday, October 22, freeing up space radiation fluctuation, which have already led to short signal destruction on Earth.
Flash coming from the sunspot AR 11958 has reached its maximum brightness at 3:22 GMT yesterday, October 23, according to scientists from NASA's Solar Dynamics Observatory (SDO),
Two cosmonauts and one astronaut and 32 live fish left Earth and went to the International Space Station (ISS) yesterday afternoon (October 23), starting with the Russian launch site, not be used to start manned missions for nearly three decades.
Spacecraft "Soyuz TMA-06M", located on the carrier rocket "Soyuz-FG", was launched on 31 th launch site Baikonur Cosmodrome in Kazakhstan at 14:51 in Moscow (10:51 GMT).
Recent images taken NASA Cassini have opened new interesting details of the release of the mysterious moon of Saturn, including nearly rounded education with a giant cross on it and seashore of ancient seas.
New findings were studied by two research groups: the first dealt with a "cross", and the second - dried seas of Titan.
The researchers presented their plans to build vneplanetnoy laboratory to determine whether it is probable to build a base for people on the moon or Mars.
The scientists from the Open University developed the conception of the tool Lunar Volatile Resources Analysis Package (L-VRAP), which will determine whether the amount of water on the moon and fuel, enough to be useful to build on it in the future scientific bases. The researchers also say that the project can be used to study the prospects of building bases on Mars.
Astronomers observe a rare type of X-ray stellar explosion near the center of our Milky Way galaxy, discovered a previously unknown black hole (BH), the engrossing gas flowing to it from the nearby sun-like star.
The find was made in the last month, NASA satellite Swift, who noticed a bright X-ray source is a few degrees away from the galactic center of the Milky Way.
Two million light-years from the center of a distant galaxy trail make bigger, surprisingly suggestive of a jet stream that reserve military fighter jet engine only in this case is a black hole, and the substance of the jet is moving at a speed close to the speed of light.
The new image of the jet which has been studied previously designated as PKS 0637-752, showing alternating light and dark areas on it, similar to the phenomenon in jet fighter jets, called "diamond condensation".

By hypothesis, Professor Eric Asfauga Planetology (Erik Asphaug), Saturn's largest moon was formed as a outcome of the merger of smaller satellites.
October 19 at the annual conference in Reno (Nevada, USA), Professor of Planetary Science at the University of California (Santa Cruz) introduced his new hypothesis that the largest moon of Saturn - Titan, was formed during a merger of at least half a dozen smaller Saturnine satellites.
At a distance of 40 light years from Earth is a planet that orbits a star and is about a third of their diamonds. These termination astronomers from the U.S. and France, the main provisions of which have been published in the latest issue of the specialized publication "Astrophysical Journal", published in Chicago by the American Astronomical Society, reports UNN.
Canadian designers are developing now several models of robots on wheels, to help astronauts learn the satellite of the Earth and other planets in our solar system. "Much of the work on the Moon and Mars will be related to the study of geology and drilling," - said Leclerc, adding that Canada is just in the technology of mining and mining has gained a lot of experience.
"The U.S. space agency - NASA has already shown interest in our prototype, offering complete them for a particular space missions, "- he said.
Scientists have make available new indication that the moon was once part of our planet, but billions of years ago, "broke away" from it in a collision with another celestial body.
Now that planetary scientists to understand where there is water on the natural satellite of our planet, all the scholarly attention has focused on the more fundamental question: how, after all, come from the moon itself? And how is it that she seemed bound rotated in space in tune with the Earth?
Amateur astronomers, dealing out the data space telescope has discovered another planet similar to their homeland heroes of "Star Wars" - it has as many as four of the Sun. Planet orbiting two pairs of stars.
Amateur astronomers help professionals in the program Planet Hunters, and process massive amounts of data obtained with the Space Telescope "Kepler". Planet with four suns - the first finding of program participants, who are willing to help scientists search for different space objects on several grounds.
The galaxy is located at a distance of 40 million light years from Earth. Astronomers Observatory "Gemini" were by far the most meticulous image of the galaxy NGC 660, which belongs to a rare class of polar galaxies. Observatory on the site (and at the observatory have a website, as the company Energostrakh, and still have a series of encyclopedias “Energostrakh "), you can even download this image to the very high resolution.

The team of scientists, which included representatives of Italy, Portugal, America and Japan, has been able to find a way that would be used for astrophysical observations that would be based on the fundamental principles of their check physics problems. In particular it affected determine the mass of photons.
The test, which was used for the scientists, is the following. If the photons would have mass, then it would cause instability, which would become the reason for stopping the rotation of black holes in the universe.
One of China's national rights of way was the development of the cosmos. Moreover resources in this country are enough for what would make the development of its space program to other countries extraordinary pace. In particular, at the recent Assembly in Beijing, Professor Sun Kwok, who has served as dean of the University of Hong Kong, said that many of the people currently living can catch the first contact with an alien race of mankind.
In recent years, the process of space exploration is not only high-status, but also and more very important. And it's not that mankind is beginning to handle in quantity boundary rules, under which the world still needed for the settlement, but because that now many of the developed countries are aiming for the development of other planets that they would start mining. To that end, in November 2013, India is going to launch on the orbits of Mars his first exploratory space probe.

Here is what happens: a thick, disordered atmosphere, where winds with speed reaching 900 kilometers per hour, a giant storm that would destroy the entire continent here, on Earth, and temperatures as high as -220 degrees Celsius. Sounds like a description of some icy hell, but in reality it is a picture of what is happening on the planet Uranus, unfolding before us on the new high-resolution images taken in the infrared range, which were obtained Keck Observatory, Hawaii.
Soon the Earth will pass through a flow of debris that is left behind Halley's Comet, and you can watch a fantastic show of heaven known as the Orionids meteor shower. This is usually a very reliable meteor shower should peak at the upcoming weekend, October 20-21, 2012, and had at this time to give up to 25 meteors per hour, according to the McDonald Observatory, University of Texas at Austin.
Saturn's icy moons medium size were twisted when several much larger satellites crash, forming a giant moon Titan, states a new study conducted by a team of scientists led by Eric Asfogom University of California, Santa Cruz.
Initially, in the Saturn system there exists a family of relatively large satellites known as the "Galilean satellites" (Ganymede, Europa, Callisto and Io), according to a new theory. But everything changed after a series of rather large collision between satellites, which are formed by Titan and was thrown into a huge amount of space matter that formed satellites such as Mimas, Enceladus, Tethys, Dione, Rhea and Iapetus, the researchers say.
NASA's Mars rover Curiosity finds few bright element in the samples, dig up his bucket from the surface of the red planet, scientists say.
Curiosity had recently dumped back taken them a sample of Martian soil, as mission scientists have noticed an unusual pattern in bright fragment, and they feared that they could be a fragment of the space vehicle or ATV. However, the particles, as it turned out, were a Martian origin.

In the nearest star to the Sun is equal to the Earth planet exposed:
From the European Southern Observatory exposed in the nearest star system, Alpha Centauri Earth mass exoplanet. New planet called Alpha Centauri Bb.
For the first time in the system of four suns discovered exoplanet Alexander Berezin How quickly time: remember, not so long ago, we still read the work seriously deny the possibility of the existence of planets around normal binary stars, because of their instability, caused by the large amount of light.
Moon could give all their water, "germ" of the Earth, scientists believe
New studies are missing puzzle to place the theory of formation of the moon as a result of the collision of Earth with a space object - a theory which has long been considered the primary version of the origin of the natural satellite of our planet. Both new research explain why the moon and the Earth have identical chemical composition, but the collision model described in these studies differ greatly, according astronews.ru.
