Given the high rate of development of methods of space exploration today, all the more incredible missions seem quite feasible. For example, NASA researchers in the future plan to capture an asteroid weighing 500 tons, put it on the lunar orbit and build a space station, which will serve as a staging post on the route Earth - Mars.
It is known that the Department of Science and Technology Policy USA (White House office of science and technology policy) will soon consider a plan for the development of such an ambitious project. According to preliminary estimates it only at the initial stage (first Read more [...]
In Morocco, the residents of one of the districts have witnessed an unusual phenomenon – huge ice fall of the meteorite. His weight was 25 kilograms. It happened in the afternoon Hrira. "Strangers from the Sky" was named "Mega-meteorite." Similar phenomena are rare in nature.
By the Earth approaching asteroid collision which will be equivalent to thousands of atomic bomb explosion. The excitement at the end of the world has not yet subsided, as the world threatened by a new attack. After ten years of our planet at a dangerous distance closer asteroid Apophis-weighing more than 99,942 million tons.
According to the professor of the Russian State Hydrometeorological University Valery Malinin to Earth approaching asteroid collision which will be equivalent to thousands of atomic bomb explosion. Ten years later he gets close to the planet. "But a lot of the time, Read more [...]
NASA satellites recorded on Venus next annular blowout. No way, as once again, a highlight was reflected in the upper atmosphere of the swamp gas.But for some reason the other satellite shoots in the same range as the Earth and never any glare to the Earth was not. And Venus has recently come, some emissions. Given the atmosphere of Venus, the conclusion is not very bright.A single shot can not see this ring, but there is clearly some visible noise.

According to their interests krasnoplanetarnym I often find unusual pictures of Mars or illustrated scientific facts about him. Some of them are so awesome that I want to run out into the street and show them to all passers-by, so they are knocked out of the stereotype of Mars as a boring "red lifeless globe." But on the street will not understand me, but here, I hope, will appreciate the amazing details of our neighbor in the solar system.The first picture - it Hephaestus Fossae - network "channels" to the west of Highland Elysium. It is made of high resolution stereo camera Read more [...]
In 2012, an article by scientists from the Institute of Technology, Tokyo, Japan, under the direction of Takayuki Saito (Saitoh TakayUKi) And it can now be found in the digital library at Cornell University, but somehow forgot about it, but in vain. The article says that in summer 2013 the gas cloud G2 will be absorbed by the black hole Sgr A * (Sagittarius A *) in the Russian translation of "Sagittarius A star", which is at the center of our Milky Way galaxy, and because of this it will light up in 100 times brighter than the sun in the infrared range of the electromagnetic radiation.

The consequence of the collision of the planet with a large meteorite and asteroid could be a global catastrophe. It is therefore important to learn to predict such events. Recently William Brukman and colleagues from the University of Puerto Rico built a new mathematical model that estimates the probability of huge cosmic bodies falling to the ground and even on Mars.There is reason to believe that the major disasters in the world were connected to the cosmos. Thus, in 1883, the Indonesian volcano Krakatoa proizoshloizverzhenie - one of the strongest in the history of mankind. Blast wave lifted Read more [...]
Scientists have shown life on Mars. A new study shows that once most of the red planet was flooded with water.
A new study by Georgia Institute of Technology (USA), shows that clay rocks and some minerals found in Martian rocks and soil, could be formed only with long-term water availability. Scientists came to the conclusion that in order to Mars formed such a large amount of clay and other rocks and minerals, most of the world has been a long time under water.
Researcher James Ray and his research team say that the original clay on Mars has been found in some rocks some of the rocks in Read more [...]
Clay minerals that form in the world, subject to availability of water, cover a much larger part of the Martian surface than previously thought. This follows from the data of the study researchers from Georgia Institute of Technology in the U.S..
First discovered clay rover Opportunity, landed on the planet in 2004. Near the Eagle crater the rover has found a hydrogen sulfate, but to get to the side of the crater Endeavour, came across traces of clay, the website sdnnet.ru.
According to the researchers, with the help of the orbiter NASA Mars Reconnaissance Orbiter near Eagle crater also managed Read more [...]
Astronomers working in Chile observatory ALMA, discovered around a star in the constellation of Sculptor unusual spiral cloud emitted substances. The work of scientists published in the journal Nature, a summary of its results portal ScienceNow. High resolution pictures can be downloaded from the European Southern Observatory. Star R sculptor located only about a thousand light-years from Earth in the constellation of the same name. It refers to a specific type of star - asymptotic red giant branch (AGB). At the beginning of its life cycle such luminaries have a mass of 0.8 to 8 solar masses Read more [...]
Many ultra bright extragalactic X-ray flares usually associated with black holes, in fact may be something quite different ...In November 2011, the ISS has registered a super-bright X-ray flares in the Small Magellanic Cloud galaxy. It lasted 92 minutes and was very unusual. It is believed that the source of this type of X-ray radiation can be vicinity of black holes, where the light material heated by accretion disks.
One flash to prevent burn due BH: X-ray emission from accretion disks gives huge temperature steadily registrable devices. And this time the temperature was too low. Fortunately, Read more [...]
According to information obtained from the probe Voyager 1, the edge of the solar system and deep space there is a kind of customs. Where the magnetic field lines generated by the sun and the presence in the solar wind undergo reconnection with the field lines of the magnetic field of the interstellar medium.
According to journalists, the device is now Voyager, zpauschenny in 1977, is close to the edge of the heliosphere, the solar region of space where solar wind plasma is moving relative to the sun at supersonic speed. As explained by astrophysicists from outside the heliosphere bounded collisionless Read more [...]
2012 was to go down in history as the year of the beginning of space mass space tourism. Ships of several private companies have been in space, proving that this sphere of human activity - space exploration, flight beyond the atmosphere of the planet - in the near future will change beyond recognition.However, about three thousand people have already bought tickets and on a thrilling journey to the stars, are still on the ground. Mass space tourism was now more difficult than expected to the founding fathers. However, this does not prevent private businesses to set new ambitious goals - to begin Read more [...]
In a recent study, researchers first took the white dwarf by the black hole, and then realized his mistake.
For a long time, the type of stars known as white dwarfs, scientists injected into error as to behave like real black holes. The study, conducted by researchers from Southampton and other countries, it was found that where the earlier astronomers showed flashes of black holes, in fact, are white dwarfs, which are perfectly disguised as black holes. Detailed results of the study were published in the latest issue of the scientific publication "The Astrophysical Journal".
Astronomers Read more [...]
In the middle of the year in the physics community interested in research in the field of black holes (BH), there was some confusion. The site appeared arXiv work that literally threatens the creation of the paradox is not the weakest of your Schrödinger cats and Maxwell's demon. In general, supported by many scholars in the belief that the information is in contact with the black hole does not go away and have a major dilemma.
Imagine that the two particles - let's call them Alice and Bob - fly around the usual black hole. Alice, being caught by the black hole gravity, crossed Read more [...]
