Something strange is going on in our neighboring galaxy Cigar (aka M82). According to one of the researchers, the British astrophysicist Tom Maxlow of Center for Astrophysics in Jodrell Bank, in May last year, watching the explosion of a supernova (SN2008iz) in this galaxy, scientists, using a network of radio telescopes, MERLIN, found that of the central part began do radio signals, different from everything they have ever been able to fix in space.
A bright spot of radio emission was held just a few days, and then sharply reduced brightness, but has not yet disappeared from sight, and did not change the spectrum. According to scientists, this is unlikely to be followed by a supernova, because it usually has a different spectrum of light. In addition, the transverse velocity of the source detected by scientists at four times the speed of light.
However, physicists do not betray this phenomenon and is called its "optical illusion." In their assessment, the same can be observed in that case, if they are a slight angle racing gas jet, heated by a black hole and speeding up to quite a high speed. Under these conditions, they say, due to the effect of the theory of relativity, and it seems that the object moves to the transverse velocity exceeding that of light.
However, the explanation does not fit the scientists real picture. Despite the fact that the galaxy similar to our cigar, it is not in the center of the black hole. All three of its black hole is not in the center, from which a strange signal, there is no black hole. Was suggested that the effect is caused by a kind of superluminal microquasar. This would be a good explanation, but there is nothing like microquasar, they should shine brighter, and besides, microquasars should radiate a powerful X-ray, which is the data subject is not emitted. "So we do not know what this thing", — says Tom Maxlow.
The galaxy M82 is located in Ursa Major, 12 million light-years from Earth. As ours, is a spiral galaxy, but in half. Its distinctive feature — the explosive birth of massive stars.
