Gas giants may face one time a year, say researchers

The researchers studied the features of the collision of giant planets with each other and found that such collisions may occur in our galaxy often.

A team of scientists from the Institute for Nuclear Research of the Russian Academy of Sciences headed by VI Dokuchaev conducted a study of indications accompanying the collision of giant planets. The researchers found that the number of collisions in our Milky Way galaxy is 0.01 to one collision per year.

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.

NASA reports of outbreaks are consistent with the version of a meteor

Witness of the flash of light observed in the sky beyond the Atlantic Coast of the U.S., recommend that the reason of these outbreaks was likely a single meteor; officials said the U.S. space agency. Witnesses described his heavenly fireworks, not skimping on the comparison.

"Judging from the brightness, we are dealing with something as bright as the full Moon, - said Bill Cooke of NASA's Laboratory meteoric environment on Friday. - Our stone entered the atmosphere somewhere in the north-east. "

Scientists say, dinosaurs became destroyed as a result of comet impact, not an asteroid

Space object which wiped out the dinosaurs 65 million years ago, it might be a comet impact, not an asteroid, a new study indicates.

180-kilometer Chicxulub crater, located in Mexico, was established as a result of the collision, which led to the extinction of the dinosaurs and about 70 percent of all species on earth, according to many scientists.

The spacecraft for the collision of an asteroid in 2022

Scientists from Europe and the U.S. to confidently move promote in their plans to make a deliberate collision of a spacecraft with a giant asteroid in 2022 to look into the depths of such visitations.

Ambitious European mission Asteroid Impact and Deflection Assessment, or AIDA, consisting of two satellites (one of which will be built by scientists from the U.S., and the second - the European Space Agency), is scheduled to start a three-year journey to the asteroid Didymus and his companion. Didim not dangerous for the Earth, so it is well suited for this kind of research, scientists said the mission at the 44th Annual Conference of the moon and planets, on Tuesday, March 19.

MESSENGER sees the smooth side of Mercury

During the two years of its location in orbit around Mercury, NASA's MESSENGER spacecraft has made ​​more than 150,000 images of the planet closest to the Sun, the solar system, first giving us the opportunity to think about the extremely rough, parched surface of the planet in feature. But not all areas on Mercury look stern and sinister: it also has a smooth side, you can see on the picture, published today.

Here we see the smooth sides and bottom Mercurian irregular depressions in high definition. 

The new company SpaceX rocket prepared for launch, scheduled for the summer

The next generation of rocket company SpaceX is prepared to fly, and it was probably he will be used to launch commercial spacecraft, which will take place this summer, the company announced Wednesday.

Merlin 1D engine was declared ready for flight once it passed the ignition for a total of 33 minutes for the 28 different tests on the premises for the development of rocket company SpaceX in McGregor, Texas.

In April, the Sun will stop distribution the commands to Mars mission

The planets in the next month will worsen due to the Mars mission. Mars will be almost exactly behind the Sun when viewed from Earth. The sun can easily interrupt the broadcast between two planets when the three celestial bodies line up in one line. To prevent incorrect signaling, dispatchers from NASA Jet Propulsion Laboratory intend to suspend sending any commands to all the Martian rovers and orbiters in April. Transmission from Mars to Earth, too, will be kept to a minimum.

Star and a black hole revolving in rapid waltz

Space Telescope European Space Agency's XMM-Newton helped discover a star and a black hole that address near each other at high speed, making one revolution in just 2.4 hours - which is an hour shorter than the orbital period of the previous record holder.

A black hole in the close pair, known as the MAXI J1659-152, at least three times as massive as the Sun, while the mass of its companion star - a red dwarf star - only 20% of the solar mass. 

Curiosity meet hill of Mars

Following spend about seven months on Mars; NASA's rover Curiosity all the time explored the area surrounding its landing zone, studying the Martian surface with its inspiring weapon store of scientific instruments. For about 208 Martian days, or nightingale, 

Curiosity rover to snooze off during a solar storm

Because of the awaiting solar storm on March 7 NASA temporarily balanced operations on the Martian surface rover Curiosity Mission Mars Science Lab (MSL). Currently, the rover mission scientists have presumed from the "sleep" mode, because the power of the solar storm was much lower than expect.

NASA has taken protection in view of the fact that a large coronal mass ejection, presumably, was to reach Mars in a few days, from March 7, the researchers say. 

Three-dimensional map of Mars water channels

Based on information get together by Mars research orbiter Mars investigation Orbiter scientists were able to create a three-dimensional map of water channels of the red planet.

A space telescope to detect extraterrestrial life

The Space Research Institute of the Netherland thinks it may be possible to identify signs of alien life within the next 25 years, without the need for a space mission.

A new method

Astronomers have speculated for decades about how observations of exoplanets could provide evidence of extraterrestrial life.

The Eskimo Nebula X-ray

The XMM-Newton space observatory agree to us to look surrounded by the covering fuzzy Eskimo Nebula, instructive a warm face gas to 2 million degrees Celsius.

This image is a amalgam of data collected by XMM-Newton (blue) and the Hubble Space Telescope (red and green), and highlights the complex nature of terrestrial nebula, the swan song of stars like our Sun .

When these stars mature, they begin to shed their outer layers to expose its core, a high temperature. 

Violent collision shaped into Vesta

The new model is based on computer simulations of collisions between asteroid Vesta separated and a couple of rocks from 32 km in diameter in the last billion years. The results suggest that cosmic impacts caused Vesta's crust to melt and then re-form, with its thicker crust than can be explained by typical rock layers, the scientists said.

Collisions carved two large impact craters on the surface of Vesta. The oldest, Veneneia, formed about 2,000 million years. With a diameter of 395 km, the crater covers nearly three quarters of the diameter of Vesta Ecuador. Covering 90% of the diameter of Vesta, is one of the largest craters in the Solar System.

The most accurate calculate of the Universe

Astronomers explore the scale of the universe by first calculating the distance to nearby objects, using them as reference points (standard candles). The close observation of a rare type of double star has allowed a team of astronomers presume a much more accurate value for the distance to LMC: 163,000 light years.

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.

Spaceship Dragon docked to the ISS

Spaceship Dragon, built by a private company SpaceX, safely reached the International Space Station - even though a day later than expected.

After the launch of the ship begin to experience serious problems: three of its four engines orientation refused to work because of a failure in the fuel system, and the operators had to spend several hours trying to revive them. It ended well, and the "Dragon", though late, but made friends with the ISS was successfully "caught" by the robot arm Canadair and docked to the station. 

A comet will pass very close to Mars

Newly exposed comet will pass very close to Mars. It is possible and collision.

Comet C/2013 A1 - the first of astronomers open this year. Its orbit is estimated to take place very close to Mars in October 2014 a comet fly only 37 000 km from the Red Planet. This in itself would be a significant astronomical event, 

Cold bed in the Sun

Observations with the infrared Herschel Space Telescope discovered the star Alpha Centauri A strange "cold bed", exactly the same as that of our sun.

Our star is composed of six layers: the core, where fusion reactions occur, areas of radioactive transfer, convective zone, photosphere, chromospheres and corona. 

Restoration Curiosity rovers

Last Thursday (February 28) fails, in which the rover operators were forced to switch from the main system to a back-in and break up research Curiosity.

On Saturday, the rover out of the "safe mode” and on Sunday again mobilized antenna with high gain. One of the options for further work, the operator in question Curiosity, 

The Depths of ocean Europe

 Found proof that the ocean in Europe, Jupiter, and a captive under a layer of ice has an exit to the surface.

The mission of Galileo (1989-2003) bring a lot of scientist’s important data about Jupiter and its moons, but the on-board infrared spectrometer probe was not able to identify all the parts needed to refine the mineral composition of the surface of Europe. Now, using a spectrometer OSIRIS (Keck Observatory, Hawaii), the researchers have made an interesting discovery.

Kepler-68b, a new type of planet

There are three types of planets in our solar system. On the one hand we have rocky worlds like Earth and Mars have a solid surface on which to put your feet and consist of 'rocks' (silicates and metals). Then there are gas giants like Jupiter and Saturn, composed mainly of hydrogen and helium (and actually should be called "Giant fluid" because most of its interior hydrogen is a liquid or metallic). Finally we have the ice giants,

Asteroid 2012 DA14 will touch the Earth

15 February 2012 DA14 small asteroid will pass so close to Earth that will be inside the ring of Geostationary weather satellites and communications satellites. NASA claims that the observations that are exactly expect the trajectory of near-Earth objects and the probability of collision exists. But the unique opportunity to study the asteroid.

"Curiosity" began to drill the surface of Mars

At the first time "Curiosity" tried his drill on the surface of Mars. According to BBC News, the robot has continually struck by a brown rock on the surface of the Gale Crater.

On the rover obtained images show traces of the chisel. Until now, the surface of the Red Planet's drill did not try. 

Light from the dark cloud

ESO shows a dark cloud in which new stars are formed straight, while a collection of bright stars, who have left their dusty nursery already.

While on the left side of the new recording sees a dark, elongated structure resembling a cloud of smoke on the right side, a small group of bright stars lit the scene. At first glance, the two parts of the image not to be contradictory, but in reality they are closely linked. 

Fire in the dark clouds

The Atacama Pathfinder Experiment (APEX) in Chile offers a beautiful view of clouds of cosmic dust in the group Orion. In observable light, this dense interstellar cloud appears dark and solid. The LABOCA camera on APEX, however, can detect the heat radiation emitted by dust and so do the hideouts of the just emerging star locate. One of these dark clouds is not what it seems.

Dense clouds of cosmic gas and dust in space are the birthplaces of new stars. In visible light, the dust appears dark and opaque so that it hides the stars behind. 

The largest-ever solar boat

American scientist’s Agency NASA makes known plans to launch in 2014, the year of the largest in the history of the solar sail. Sail area of 1.2 thousand square meters. The name of this project served as a famous story by Arthur C. Clarke of 1964 Sun jammier, which refers to the regatta "solar boat". Side length of the sail is almost 38 meters high, and it will produce L" Grade - the company that in the late twentieth century sent experimental" inflatable "antenna on the ISS. 

Make stars are born

Astronomers have calculated that the birth of planets around young stars can occur even at a later stage than previously considered. In the study of the properties of star TW Hydra found strong evidence. This star is at a distance of 176 light-years from Earth, refers to the spectral type K8 and attracts the surrounding gas and dust astronomers drive. A few years ago, close to the TW Hydra was discovered planet, which weighs slightly larger than Jupiter.

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.

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.
