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referring to the still unpublished article for the magazine scientists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 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.

glow of dark galaxies.
The

'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.
