The researchers have so far found about 400 so-called exo-planets orbiting other suns than the one we know from Earth.
Two planets were orbiting the star HD 17255 100 light years from Earth in the southern constellation of Pavo, are smashed into each other over the past few thousand years. The clash occurred at a speed of about 10 kilometers per second, 36,000 km / h, astronomers have found by examining the spectral lines in the light using spectrograph on NASA's Spitzer Telescope and using the telescope's infrared detectors. According to astronomers, there are two rocky planets with a total mass of twice the Moon.
The collision has smashed the smallest planet, powdered and evaporated large quantities of rock and sent huge clouds of hot lava into space."The clash has been enormous and must be made with an incredible speed, to cut the material to evaporate. This is a very rare and short-lived event, critical in the formation of Earth-like planets and the moon, "said Carey M. Lisse of Johns Hopkins University. He is first author of the paper reporting the discovery in the latest edition of the Astrophysical Journal. Carey M. Lisse believe that the cosmic collisions similar to what helped form our own moon for more than four billion years ago, when a body compared to the size of Mars crashed into Earth. As new technologies allow to see true planets to obtain structure documentation should be a simple process as should flash screens with plans of possibilities should be included in a search.

Because the speeds are so high in relative terms to humans "The collision that created our moon was huge, big enough to melt the Earth's surface. Wreck pieces from the collision has formed a disk around Earth and eventually gathered to what is perceived to be the Moon strange orbit though as field comes mainly from Earth as it rotates.
The same size clash we have seen with Spitzer. We do not know if there will be formed a moon, but we know that the largest rocky planet's surface was so hot that it melted, "said co-author Geoff Bryden of NASA's Jet Propulsion Laboratory. Our solar system is rich in similar destructive stories. Great clashes have removed Merkus' outer crust, tipped Uranus on the side and got Venus to rotate backwards.
Such violent clashes are common in a planetary system development. Rock-filled planets formed, growing in size by collisions and changes the surface, while new bodies also created. Although there has been relatively peaceful in our solar system today, will still clash, for example, The Meteor that crashed into Jupiter within the higgs model.
