Jupiter's moon Europa attracts scientists stronger than Mars

American astronomers who are searching for life in the solar system, believe that Europe, one of the moons of Jupiter, the surface of the ocean where there is a much more attractive target for new expeditions than desert Mars, now riveted the attention of the U.S. government.Europe has become a tempting target for the search of life on it, because it has a fairly thin crust of ice, which is hidden under the ocean. Also in Europe contains chemicals-oxidants, say planetary scientists.At the request of NASA has been recently revised new mission to Europe in order to reduce the project cost, and the Read more [...]

Cassini disappearance of craters found on Titan

01/21/2013 Scientists working with the data device "Cassini", found that wind erosion processes lead to the rapid smoothing of the craters on Saturn's moon Titan. The paper was published in the journal Icarus, and its website a summary of results of the American space agency. The discovery was made by comparing the ratio of the diameter and depth of craters on Titan and Jupiter's moon Ganymede. In the case of Ganymede depth data were obtained using stereofotografii held device "Galileo." Information about the craters on Titan were obtained using radiosonde conducted Read more [...]

Scientists hope to find traces of life at the bottom of Martian craters

Deep craters on the surface Mars contain traces of clay, which are formed only in the presence of ground water. This suggests that the Red Planet could be liquid water, and thus life.It is believed that the surface of Mars in ancient times, in Noah's age (3.8 - 3.5 billion years ago), there were oceans and rivers of liquid water. Weight and dimensions of the Red Planet are too small to hold the large and dense atmosphere, resulting in water gradually disappeared.Probe MRO (Mars Reconnaissance Orbiter) found in the second half of the 2000s. many deposits of clay, which is hidden inside a Read more [...]

Giant moon hole — a place for extraterrestrial base

Spacecraft Lunar Reconnaissance Orbiter (NASA) has made the most detailed to date photographed two giant holes in the surface of the moon. These holes appear as black holes, going deep into the satellite, and are of special scientific interest. Scientists believe that the dark gaps are the result of the destruction of underground lava tubes. As a result, any impact may meteorite impact, some rocks fell into the depths, forming a rather smooth deep dip. In fact it is a kind of cave with the collapse ceiling, which offers researchers a deeper, inaccessible in normal rock layers. One of these holes Read more [...]

In the center of the Milky Way lies a giant black hole

It is believed that at the center of the Milky Way lies a giant black hole, but nobody ever saw her. Now, astronomers were able to predict, might look like a black hole in the first photographs obtained by technology that will be available very soon. The researchers found that the picture of a black hole, or, to be more accurate, the border around the crescent will form, not shapeless, as they represent.Scientists say that by modeling these photos, they are preparing for interpreting images that will soon be obtained using telescopes that are currently under construction.Ayman Bin Kamruddin, Read more [...]

Martian river Reull Vallis

Of "Mars Express" to explore yet another river on Mars, the name of which Reull Vallis. Research probe "Mars Express", a European Space Agency (ESA), at the end of last year, took a picture of Mars region called Reull Vallis with its high-resolution stereo camera. This rekoobraznaya structure. The photos show the mouth of a dry river. Scientists suggest that in the past there was a river of liquid water, which had a fairly strong current. Hence a clear track in the photo. Under different conditions, such a trace could not be formed.According to scientists who study Read more [...]

On Saturn's moon craters disappear

On the planet Titan, Saturn's largest moon spontaneously disappear deepening. It is able to detect with interplanetary probe "Cassini". Scientists believe that the unusual phenomenon is important for understanding the history of Titan. The discovery was made when comparing the ratio of the diameter and depth of craters on Titan and Jupiter's moon, Ganymede. Most of the pits on Titan contained an unusual sand from bicarbonate. On the surface of the moon craters were as empty and filled up to the top. Scientists have linked the process of filling in the craters and the disappearance Read more [...]

Supermassive black holes are growing faster than people think

In large galaxies growth of massive black holes at the center is proportional to the square of the increase in mass of the galaxy, say Australian astronomers. For years, it was commonly believed that supermassive black holes (SMCHD) in the centers of galaxies gained its colossal mass, which sometimes up to 20 billion solar, gradually, step by step, absorbing their surrounding matter. But with the growth of the mass of the nuclei and the "weight gain" of the galaxy and tuchneli SMCHD. Therefore, knowing the mass of the galaxy, astronomers have believed it possible to shortchange its Read more [...]
