No one understands how did this signal. Some even think that he was sent extraterrestrial civilization. Bright mark on a blue background — an abnormal signal, a registered land radio telescope
as part of SETI (Search for Extraterrestrial Intelligence, SETI). Search for signals from extraterrestrial intelligence is a number of groups, including volunteers from the League of SETI. The vertical axis of the figure shows the time and the horizontal — the frequency. Although the causes of this strong signal is not known, astronomers are finding it a lot of the characteristics peculiar to the signals of terrestrial origin. The most reasonable explanation for this event is unusual modulation between signals on satellite navigation system (Global Positioning System (GPS) and terrestrial unidentified source. Many unusual signals from space remain undeciphered. But still no signal
was not sufficiently intense and prolonged to be able to say with confidence that its origin is associated with an extraterrestrial civilization.
