    There are various methods which have suggested and convinced astronomers that black holes exist. In particular, a technique used by astronomers to locate both stellar and super-massive black holes is to observe the motion of stars in the area around the supposed black hole.[4] Most stars in our galaxy are formed in groups of two or more stars, by observing the visible partner of a binary system, astronomers can effectively trace a black hole. Astronomers can calculate the mass of a black hole quite simply, using Keplar’s laws of motion, this is done by determining the velocity at which the partner star is orbiting the black hole. Generally if an object has a mass three times the sun or less it is a neutron star, if it is greater than that it is most likely a…

    For about fifty years now, astronomers have been detecting particles with energies greater than eight billion electronvolts "bombarding" Earth. Up until now, the origin of these particles has been a mystery. The reason the answer took so long for us to get, is because these high charged particles only falls on about one square kilometer of Earth per year. With this little amount of impact, it was quite difficult for astronomers to determine its origin. This miraculously changed when the same type of cosmic rays hit three thousand square kilometers of some Argentinian grasslands. After this large accumulation of cosmic rays hit, many people thought it had come from the center of the Milky Way, as it had been known to contain celestial objects that can accelerate objects to at least a million billion electronvolts. After steady research by the Pierre Auger Collaboration, the belief of these particles coming from the Milky Way were proven to be false. They found this out by detecting the…
