GTC to unravel the mystery of the atmosphere of one of the 'super-Earths'
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.

Where to look for the "perfect storm"?
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.
Vesta close-up the machine Dawn
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.
The largest fully steerable radio telescope built in Asia
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.
Our galaxy caught for dinner: Milky Way star absorbs
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,
Discovered the most rapidly rotating superdense star
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.

Trillions of comets collide around Fomalhaut
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.
Enormous image of the center of the Milky Way
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.

Cassini sees giant energy flow on Saturn
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.
The giant exoplanet zombie rises from the dead
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.
The smallest supermassive black hole
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,
Complete rotation of Jupiter, by Damian Peach
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.
A halo of NGC 6164
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,

Globular clusters show: how galaxies come in several waves
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.
The sun
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,
43rd Week - The cometary star forming region G110-13
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.
Pulsars as detectors for gravitational waves
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.

California was the usual stone meteorite
Clash, which, as predictable,
could be from a recent meteor fireball that flounces over California, in fact,
was the usual earthly stone, scientists reported.
Stone interested
researchers, because it was assumed that he was a first portion, which had been
left meteor lit the night sky over the Bay Area of San Francisco on October 17.

Quasar J1148 +5251, scientists have discovered around stars
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.
A large X-class flare on the Sun
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),
Expedition 33/34 went to the ISS
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).
Pictures taken Cassini, discovered a "cross" on Titan
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.
Whether to build a base on the moon
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.
A rare explosion of a star discovered a black hole in our galaxy
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.
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".

Titan was formed, merger of smaller satellites of Saturn?
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.
The planet, which is a third of the diamonds
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.
Canada has produced a prototype for future Mars rovers
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.
Moon was once part of the Earth!
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?
Found homeland heroes Star Wars
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.
Astronomers photographed unusual polar galaxy
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.

Scientists have shown photon mass
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.
The Chinese will find the aliens in the next 20 years
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.
India will send its own mission to Mars
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.

Uranus observed unusual weather
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.
Orionids meteor shower will climax this weekend
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.
The unusual origin of Saturn's moons
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.
Curiosity digs on Mars glittering particles
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.

A twin of Earth in the Alpha Centauri system
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.
Earth took its water from the moon
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.
