The mysterious birthday Neptune

Neptune is approximately 4400 million kilometers away from Earth. Neptune is about to celebrate its first birthday. On July 12 will be a year-Neptunian-terrestrial or 164.79 years since its discovery on September 24, 1846. But why do we know so little about the distant planet?

At approximately 4400 million kilometers from Earth lies Neptune, the first planet in the solar system to be discovered deliberately. After classification of the planet Uranus in 1780, astronomers have been puzzled by his strange orbit. Scientists concluded that either Isaac Newton's laws had a fundamental flaw or something else-another-planet Uranus was pulling its expected orbit. And so began the search for the eighth planet.

Mercury shows best kept secrets

Mercury place in foreign hidden craters, volcanic nature has an powerful, large amount of sulfur and convulses with energy blasts. These are the first findings of the data obtained by NASA's Messenger probe.

After nearly three months orbiting Mercury, this device has sent to Earth new data-with some surprises, on the composition of the Solar System planet closest to the Sun. The probe entered orbit around Mercury on March 18 and thus became the first spacecraft to achieve.
