European probe "Venus Express" continues to explore the second planet from the Sun - Venus. Some discoveries have plunged scientists puzzled.

For example, a giant double crater in the planet's atmosphere. A series of images showed that the shape of a mysterious vortex varies in height. To elucidate the reasons for the formation of such a phenomenon will probe a new series of photographs, and scientists will carry out simulation of "Venus" craters on the computer.

In addition, it was found that the upper layers of the planet's atmosphere absorbs unusually hard ultraviolet. However, to determine exactly what substance is causing such a strong absorption, has not been possible. It is known that these "sinks" are a kind of bands. The Earth absorbs the destructive ultraviolet ozone layer.

Finally, at an altitude of about 20 km in the clouds have been discovered a fairly large drops of sulfuric acid. On our planet, it gets into the atmosphere by volcanic eruptions. Perhaps similar processes are at present and on Venus.
