Noting the weather patterns of a brown dwarf

Hubble space telescopes and NASA's Spitzer investigated the stormy atmosphere of a brown dwarf called 2MASSJ22282889-431 026, creating the "climate map" far closer to this kind of cold orbs similar to stars. The forecast shows clouds planet-sized wind-driven involving these strange worlds.

Brown dwarfs are formed from the condensation of gas, as do the stars,but lack the necessary amount of mass to fuse atoms and energy.

Venus, ionosphere swells in its night side like comet

The ESA’s some unique observations of Venus through a period of low solar wind pressure, discovering that the planet's ionosphere swells in its night side, like the tail of a Comet.

The ionosphere is a weekly electrically charged gaseous region far above the main body of the planet's Atmosphere. The form and are partially controlled by the internal magnetic field of the planet.

Taimyr bacteria were able to live on Mars

US-Russian group of Scientists found the frozen bacteria of Taimyr bacteria, which can develop in the temperature, pressure and oxygen attentiveness matching to the Martian Atmosphere.

The paper was published in the journal Proceedings of the National Academy of Sciences, and a summary of its results in Spiegel Online.

A structure of stars

The complicated filaments of dust and gas that make up this astrophysical nursery home to more than 600 stars in formation. This province was first observed by the Herschel space observatory of ESA.

The province colored blue nebula, known as W40, or Sharpless 2-64, is located 1,000 light-years from Earth in the direction of the constellation Aquila,

As feline parasite infects humans

Czech biologist Jaroslav Flegrei is known for his statement that the common freeloader known as Toxoplasma (Toxoplasma gondii) is able to "manage" the human brain.

Toxoplasma is which usually affects cats, known with scientists through their "smart tactics." Coming from a cat in a rodent parasite makes him fearless, directing poor straight into the jaws of a cat. The freeloader multiplies in the cat, then the feces is disqualified, thus again can get to the rodent.

Flegrei discovered that people infected with the parasite, it is peculiar behavior like rats: slow reaction, lethargy and reduced fear. But until recently, scientists did not know the mechanism of the nervous system.

Life in thunderclouds

The storm clouds in the Earth's atmosphere found wealth microbial life.

Scientists investigated the chemical composition of hailstones. As a result, found several types of bacteria that are usually found in plants, and organic compounds that are commonly found in soil. Were bacteria, which produce pink pigment, which protects them from UV rays?

Manatee’s nebula looks like a giant fish

Scientists have called the nebula W50 Manatees. What was the reason for this?

Nebula Manatees only recently got its own name. Until recently, it was more commonly known under the designation simply W50 and SNR G039.7-02.0.

This nebula, which in shape look like a giant fish, nestled in 18 000 light-years from Earth in the equatorial constellation Aquila.

Curiosity calcium deposits found on Mars

Fourth American rover named “Curiosity " continued their research on Mars, throughout the last of which he found deposits of calcium.

Most excellent photo of the Sun from NASA

Astronomers from the Solar Dynamics Observatory (NASA) for the first time took a photo of our central achiever in high definition.

We have not had time to approve of the photographs of the Sun made by Solar Dynamics Observatory, but this time the picture was in use in a high resolution, which officials said NASA, that smooth the most modern TV Ultra-HD TV cannot show it at full resolution.

Spacecraft "Solar Dynamics Observatory" (Solar Dynamics Observatory / SDO), launched by the American space agency, in February 2010, is "guilty" of the most stunning images of solar flares.

Moon Illusion

Presented another answer to the age old question of why the moon comes into view larger close to the horizon than at the pinnacle.

Joseph Antonides and Toshiro Kubota from Susquehanna University (USA) re-opened the debate around the famous optical illusion. According to their theory, the illusion is due to inconsistency between the estimates of distances, which allow the brain is subjective picture of the world and according to binocular vision.

First time Martian rock drilling ready

Curiosity rover is get ready to hold the first Martian rock drilling - in a carefully selected for this purpose, which in the history have to splash water.

Extraordinary ton machine should start work in the next couple of weeks.

Reprogramming Leprosy

Investigating the mechanisms of spread of leprosy (leprosy) in the body, scientists have noticed that its agents - bacteria Mycobacterium lepta - can exchange mature cells into stem cells (which can develop into different cell types).

Researchers have identified lemmotsity mice and infected them with agents of leprosy.

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.

ALMA makes gas flows visible on the planet formation

Astronomers using the Atacama Large Millimeter / submillimeter Array (ALMA) for the first time to directly observe how extensive gas streams overcome a gap in the disk of matter around a young star. In theory, should such gas streams arise during the growth phase of planets? This is a key stage in the birth of the gas giants. The observations are the second January 2013 published in the journal Nature.

New View of the globular cluster 47 Tucanae

Globular clusters 47 Tucanae are huge spherical cloud of old stars held together by gravity. They are turning around the cores of galaxies, and satellites orbiting Earth. These groups of stars contain very little gas and dust - it is believed that most of the cluster has been driven by winds and explosions of stars it contains, or has been torn by the interstellar gas has been interacting with the cluster. Any remaining material coalesced into stars billions of years ago.

Reverse Effect: Eruption of climate

The eruption can cause climate change, no doubt. Supervolcanoes that send to the stratosphere many tons of ash may affect the global climate. But it appears that perhaps the reverse effect: the German and American scientists have found evidence that climate can change the activity of volcanoes.

This is something new! However, researchers at Harvard University in collaboration with the center GEOMAR know what they say on their side - the results of the analysis of volcanic deposits in the last million years.

Mars rover Curiosity explores lowland Yellowknife Bay

The Mars rover Curiosity, a key element of the mission Mars Science Laboratory (MSL) NASA resumed traffic January 3 and drove right up to the twisting geological formation, called Snake river ("Zmeistaya river").

Snake River is a thin curved line of dark rock, running through between flat slabs of lighter rocks and towering over the sand. Curiosity rover science team plans to study this form of relief in detail, before switching to other nearby rocks.

Maximum of solar activity in 2013 is expected to be the weakest

Maximum activity this year is likely to be the weakest in at least the last 100 years, according to NASA scientists observing the nearest star to the Earth every day.

The number of sunspots is low, despite the fact that the sun is close to the maximum of its 11-year activity cycle. Furthermore, the intensity of radio waves, usually pointing to the high solar activity, also significantly reduced.

The first direct detection sheds light on dark galaxies

Most people think of the giant galaxies as islands of stars, gas and dust that block our universe with its light. Theory, however, predicts that there are other types of galaxies, devoid of stars, and consisting mainly of dense gas. These "dark" galaxies you can not see on the black background of the universe.

Now an international team of astronomers has found a few bright galaxies, watching the glow of hydrogen these galaxies, UV-induced nearby quasar HE0109-3518.
