Record breaking flies from black hole


Quasars are very distant galaxies with extremely luminous core areas. Astronomers believe that massive black holes are the source of kvasarernes high energy show.

The supermassive black holes in quasars create such strong and very energy-rich effluents of material ejected and affect their surroundings. Astronomers have now found the most energetic outflows from a quasar ever.

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.

At the edge of the visible universe


At the edge of the visible universe almost the farthest galaxies are more than 13,000 million light years away. Their light has taken that long to reach us. This means that as we were more than 13,000 million years, only 500 million years after the Big Bang. Therefore, more distant galaxies are also the oldest in the Universe. The most distant galaxy discovered to date is the Abell 1835 IR1916. It is located behind the cluster Abell 1835, in the constellation Virgo. It was discovered in the year 2007 by European scientists. This is 13,200 million light years away and each time more.
