American Dawn probe discovered the asteroid Vesta mysterious winding ravines - channels, cutting some craters. Scientists point out that they are very similar to those of the water flow.
According to Jennifer Scully of the University of California at Los Angeles, straight depressions were not surprised the researchers, because these are also found on the moon - they are an example of the flow of dry material, such as sand.
- But these winding valleys - it is something unusual, we did not expect to find them, and are still trying to understand their nature, - she said.

Despite the irresponsible statement by a NASA employee and internet rumors, for samples of Martian soil for signs of life were found. Anyway, to be honest, is not registered anything that could be compared at least with the data of the last generation of Mars rovers. Curiosity rover first used all the tools for the analysis of Martian soil and found in a sample of the complex chemistry: found water, sulfur and substances containing chlorine.
That's it. In 2008, when rumors spread that the station "Phoenix" found on the Red Planet signs life, NASA quickly held a press conference Read more [...]
Researchers concluded that on Venus from time to time there are volcanoes, changing the composition of the global atmosphere.
The presence of volcanoes on Venus indicates a significant amount in the atmosphere of sulfur dioxide (SO2). On Venus, the gas, as on Earth, where its concentration is less than one in a million times, in all probability, is of volcanic origin.
Scientists, however, for a long time could not establish whether the volcanoes of Venus acting or they died out long ago, throwing SO2.
Authors of failed to answer this question by analyzing observations apparatus "Venus Express", Read more [...]
