Solve the mystery of the missing gas clouds, quasars


Scientists have been able to unpick the mystery arise just a few years of disappearance in 19 quasars gas clouds.

The internal structure of quasars - the ancient galaxies, the luminosity of which are so high that they can be confused with the nearby bright star - has interesting features. When approaching the central black hole accretion disk galaxies substance strongly heated and emits more light than the rest of the stars of the galaxy together. Powerful wind of charged particles generated by the heated gas, thus can take a portion of the incident with the black hole matter.
