Astronomers were able to take a picture of "The Decline in Mordor"

Scientists from the European Space Agency / European Space Agency, ESA / Hubble using / Hubble Space Telescope, HST /, which is currently orbiting the Earth, got a photo and called it "The Decline in Mordor." The picture shows clearly seen darkening cloud, due to which light penetrates the star, which was formed recently.

Astronomers are digging under the brown dwarfs

Astronomers have focused all their attention on brown dwarfs, trying to uncover all of their secrets. Despite the fact that brown dwarfs are not the full-fledged stars, and substars and occupy an intermediate niche between these massive stars and planets, they cause enormous interest among scientists. Astronomers from around the world are trying to figure out what is more like brown dwarfs: the planets or stars. What a performance they made more or are they still are an entirely different stage of development than the traditional brown dwarfs and planets. In addition, the astronomers looking for protoplanetary disks around brown dwarfs, and the worlds that are formed in these disks.

British Astronomers have first color of exoplanets

British astronomers have for the first time were able to determine the color of exoplanets. With the help of a telescope "Hubble" researchers from Oxford University Conducted a spectral analysis of the stars in the constellation Vulpecula, and where able to calculate the color of the planet orbiting HD 189733 b. Details referring to the still unpublished article for the magazine scientists Astrophysical Journal Letters lead Nature News.

Since the star is too far away, 63 light years from Earth,

Astronomers have cataloged galaxy collisions


Collisions between galaxies, it is a fairly common phenomenon. Almost all of the galaxies involved in one or More collisions during its existence. One example can provide as our Milky Way galaxy, is sent to the Andromeda galaxy, our nearest galactic neighbor, at about 50 kilometers per second to run into her in about a billion years.

A group of researchers from the Harvard-Smithsonian Center for Astrophysics used the results of the latest observations of 31 interacting galaxies located in fourteen systems to carry out the first systematic analysis of the distribution of energy in the interacting galaxies over a wide spectral range.

Astronomers have discovered a new group of Trojan asteroids of Mars


Astronomers from the Arman Observatory, United Kingdom, led by Apostolos A. Christou reported finding a new family of Trojan asteroids of Mars.

The orbital evolution of the detected lasted about 100 million years, scientists say, and the orbits of the asteroids orbit recall now the largest of the known Trojan asteroids of Mars Eureka 5261. This group forms a cluster within a region of space, which is usually the most stable are the Trojan asteroids.

Astronomers, first time directly observed a planet


An international Astronomers team lead by Sascha Quanz from ETH Zurich in Switzerland examined the gas and dust disk around the young star HD 100546, which is located at a distance of only 335 light years in relative closeness to our solar system. The researchers were surprised when they found evidence of a planet that - surrounded in the disk of theme around the young star - is still in the development process. This possible planet would be a gas giant similar to Jupiter in our solar system.

Astronomers have exposed the largest structures in the universe


A group of British astronomers exposed the largest known structures in the universe. This is a group linked by a single gravitational field of active galactic nuclei, which make bigger from one end to 4 billion light years away. Scientifically verbal communication, the structure is a large group of quasars.

Astronomers, discovered a planet, 13 times greater than Jupiter


This finding sheds light on the formation of new planets. Mass of the new planet is 13 times greater than the mass of Jupiter, the largest planet of the solar and heavy systems. Previously, scientists doubt that the planet can be formed from a protoplanetary disk as massive stars, like Kappa Andromeda. To date, more than 800 planets discovered outside our solar system, but scientists have been able to photograph a few of them.

Astronomers have discovered a potentially habitable planet


Found a planet that can support life on Earth. In addition, it is not so far away newly discovered planet is a so-called super-Earth.

Astronomers led by Mikko Tuomi from the University of Hertfordshire re-analyzed data from the spectrograph HARPS, concerning the star HD 40307 in the constellation Pictoris, and opened just three new planets, one of which is right in the center of the habitable zone lights.

Astronomers have discovered a change in color of Pluto


Scientists have observed on Pluto, during many years of computer analysis of the images the telescope "Hubble", strange activity, due to which, in recent years the world has changed color.

Heavenly body began to rapidly turn red, and its northern hemisphere was a little brighter.

Astronomers studying the "jet stream" age in two million years


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".

Astronomers have calculated the ancestors of the Sun


Two astronomers at the Geneva Observatory, and Georges Mathieu Gunel Maine, recently declare that they were able to build out what looked like "ancestors" of our sun. As you know, the birth of stars is in the depth of the gas-dust clouds, "metals" which are the remains of already dead and exploding stars that were ejected into interstellar space and the force of the explosion that ultimately form these same gas and dust clouds.

Another flash on Jupiter


Amateur astronomers dotted a brief fracture have of light along the eastern limb of Jupiter. Now we must wait to see if the planet bears a scar from the impact site.

This is the perfect time to observe Jupiter. Shines brightly Queen planets in the night sky - That means clustering and a lot of eyes and cameras are turned on it every night since about midnight Until Dawn. HAS paid all this early in the morning of September 10, when two amateur astronomers have captured a spectacular goal brief lightning in the middle of Jupiter near icts eastern limb.

Astronomers Release the Largest Ever Three-Dimensional Map of the Sky


Cambridge, MA - The Sloan Digital Sky Survey III (SDSS-III) has released the largest three-dimensional map of massive galaxies and distant black holes ever created. The new map pinpoints the locations and distances of over a million galaxies. It covers a full volume equivalent to that of a cube four billion light-years on a side.

Astronomers first observed dark galaxies in the early universe

Astronomers has observed first dark galaxy, an early stage of galaxy formation, said the European Southern Observatory (ESO) from its headquarters in the German city of Garching, to the south.

Scientists used the long-range telescope (VLT, for its acronym in English) Cerro Paranal Observatory in Chile, which managed to detect these gas-rich galaxies that do not contain stars, noting its brightness when illuminated by light of a quasar.

'Dark Galaxy' continues to astronomers


The Hubble Space Telescope has failed to reveal the expected number of stars in the mysterious cloud of hydrogen on the size of a galaxy known as VIRGOHI21.

The research reinforces the idea that the gas cloud is the only known example of a "dark galaxy" that never initiates the birth of a star.

It is thought that a galaxy is formed of normal matter, or which has collected in clouds of hypothetical dark matter. But scans have shown fewer galaxies than expected, suggesting that, for unknown reasons, 

Astronomers have open a galaxy of split personality

Astronomers working with the telescope Spitzer released new images of NGC 4594, known as the Sombrero.  As a result, the researchers found out that it "suffers from split personality" - inside the giant elliptical galaxy essentially is a small spiral.  Article scientists appear in the journal Monthly Notices of the Royal Astronomical Society, and its summary is provided on the site of NASA.
