It appears from our home Galaxy is very good appetite! Still milky Way regularly "eats" small galaxies and star clusters, and the deeper they fall into its area of gravitation, the stronger draws them in. However, in this gluttony positive side - swallowed all the stars become part of our Galaxy.

Such strongest flash from the area of a supermassive black hole at the center of the milky Way humanity is not yet fixed.

Why the surface of the asteroid Vesta looks like she was born, but actually Vesta is the age of the Earth? Why is it not recognizing the space weathering? Some astrophysicists explain this by the fact that perhaps Vesta has a magnetic field, which reflects the particles of cosmic dust and solar wind.

Exactly 45 years ago in Russia began to broadcast TV programs via satellite communication channels. Today is the anniversary notes the state enterprise "Space communication".

The Orion nebula has long attracted the attention of astronomers its strange. Its stars are so unusually high rate that it seems as if all the congestion we shall soon go on a separate disc. In addition, there is too little (in comparison with the average of the stellar population in the galaxy) major stars, and the share of small overly loud.

Rebecca Martin of the University of Colorado at boulder and Mario Livio of the Institute for space telescope in Baltimore have developed a rather extravagant theory, suggesting that for the formation of life on Earth in the Solar system must be the asteroid belt, according to where it is now. Otherwise you would not! This leads to the following conclusion: the search for extraterrestrial life should be to focus on those systems that are close to the "snow line" has its own asteroid belt.

Recent research astronomers refuted the popular idea of the galaxies as an immutable and extremely stable structures. It turns out that they are constantly changing, struggling with entropy, and thus they themselves bring it within yourself. It lasts at least the last 8 billion years. Previously, scientists simply "otbrakovyvanie" variable of the galaxy.

European astronomers has used the newly built LOFAR telescope to obtain high-quality images bubbles of hot gas - "ears" supermassive black hole located in the center of the galaxy M in the constellation of Virgo, and published their article in the journal Astronomy & Astrophysics.

In the American state of new Mexico will be conducted the experiment on the cooling of the atmosphere of sulphate aerosols. Such aerosols emitted by volcanoes erupted. They reflect solar radiation and contribute to the cooling of the Earth's atmosphere.

Since prehistoric times, it is known that on a flat star "carpet" places across holes - areas where the stars or see very little or hardly visible. Particularly well such failures are seen on the background of the milky Way (of course, in those places where the level of illumination of the sky lets you see the milky Way).

The fall of the asteroid to Earth again at the hearing. Postgraduate student of the Department of Aeronautics and Astronautics at mit offered an unusual way of dealing with this cosmic threat. A bold idea inspired his game of paintball. Yet there are no calculations and the experimental part, however, the concept is clearly deserves attention - watch the video.

Just a few October day we learned about exoplanets as much as never learned for all the previous months. Main news: now why to fly to the nearest star.

In 2008 was discovered exoplanet the star Fomalhaut, but when the data were re-examined by another group of scientists, open planet discovered. Astronomers did not give up and images from the telescope "Hubble" reviewed again, and lost earlier exoplanet found, because astronomers managed to fix the traces of the shots of the star, which is located in twenty-five light years from earth in the southern constellation Pisces.

After almost 40 years of work with technologies that allow you to display manned space vehicles not beyond earth orbit, U.S. space Agency NASA, apparently, decided to invest in deep space.

Using NASA's x-ray telescope Chandra at the core of a spiral galaxy NGC 4178 type SBcd located at 55 million light-years from Earth in the constellation Virgo, found a bright x-ray source, which astronomers believe a black hole with a mass of just VAC 104-105 Solar masses. This is the most low-mass of the supermassive black holes (SMCG)observed in the centers of spiral galaxies.
