Studing the orbits of Kleopatra’s two moons, named Alexhelios and Cleoselene, which will be discovered in 2008, astronomers discovered that asteroid Kleopatra is a pile of rubble and not a solid object. Because of astronomers knew Kleopatra’s orbit, they were able to use data from various telescopes
NASAs Kepler spacecraft has discovered 170 planetary systems keeping between two and six transiting planets.According to new study alien solar systems with multiple planets are enough different than our Solar System.NASA’s Kepler Space Telescope detected 1,235 alien planet candidates in its first four months of operation, 408 of them is in multiple-planet systems.
On April 12, 2011, NASA’s Fermi Gamma-ray Space Telescope detected the most powerful in a series of gamma-ray flares occurring in the Crab Nebula. The Crab nebula, which is located 6,500 light-years away in the constellation Taurus, is the crash of an exploded star that emitted light and reached Earth in the year 1054.
During the studies of the meteorite NWA 1934 researchers discovered the oldest mineral of Solar System, called Krotite, CaAl2O4. The mineral was named in honor Alexander Krot. According to researchers mineral formed at very high temperature and low pressure during the cooling of molten material in the protoplanetary disk that surrounded the Sun. Age of the meteorite, which was discovered Krotite, CaAl2O4l, is more than four and a half billion years and the mineral is even older, which makes it the oldest known minerals in our Solar System.
According to director of the Institute of Astronomy RAS (INASAN) Boris Shustov, Solar system within its visible part detail “inventoried” and there are no unknown planets or other celestial bodies massive than the average asteroid
With the help of the Cassini spacecraft, Nasa has received new data about that the surface of Titan, Saturn’s moon, was formed under the influence of weather and outside influences, such as meteor shower, and not as a result of volcanic activity.
