On the asteroid Vesta, discovered a giant "snowman" - an anomaly!
The American space probe "Dawn" is sent to Earth photographs of one of the most ancient and mysterious asteroids - Vesta. Astronomers have long been hunted for him, but no one expected to find on its surface "snowman".Satellite-cartographer "Dawn" was trying to find traces of water on the asteroid, there is evidence of life, but ran into a giant snowman. He was, alas, is miraculous - it's a triple crater. The exact dimensions of scientists have yet to figure out.The asteroid Vesta - the brightest in the sky. Such large bodies were created in the asteroid belt between Mars and Jupiter, about four billion years ago, ie in the early stages of the solar system."West - one of the unique instances of such an ancient period of the existence and formation of our system. We are very pleased that we now have the opportunity to get acquainted with a variety of features of the asteroid's surface," - said Christopher Russell, supervisor of the project.Asteroid shape resembles a soccer ball pierced. The most notable feature of the landscape - a huge crater at the south pole, which is certainly a huge scar after a collision with another celestial body. Unusual asteroid discovered German astronomer Heinrich Olbers in 1807. But neither then, nor 20 years ago, when Vesta looked at with a telescope "Hubble", such high-quality images and video all the more scientists were not available."One of the most amazing aspects of this mission is that we had the opportunity to explore one of the most neglected areas of the Solar System. Vesta - this is the only asteroid that can be seen with the naked eye from Earth," - said Marc Rayman, chief engineer of the project.NASA ironically, why not melted snowman, because an asteroid, just as on Earth, it's summer? Now the end of the summer season in the southern hemisphere of Vesta, so a large crater at the south pole of the sun lit up. With this calculation and sent the probe to an asteroid - let the summer there and it lasts more than 11 months.
Is this object artificial? NASA's Dawn spacecraft obtained this image of the giant asteroid Vesta with its framing camera on July 24, 2011. It was taken from a distance of about 3,200 miles (5,200 kilometers). Dawn entered orbit around Vesta on July 15, and will spend a year orbiting the body.
