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.

The database project in space

NASA is going to throw astronauts to the libration point of the Earth-Moon system, thus developing the idea of going beyond low-Earth orbit, already moderately alive in the spacecraft "Orion".

NASA scientists want, based on the experience of international cooperation in the ISS project, to place equipment and astronauts to the second Lagrange point (L2) of the Earth-Moon system.

The victim of a supernova explosion

Scientists are trying to way down the star, which died in the explosion of a supernova that transpires in the past year.

The outbreak of the star was found May 31, 2011 in a rather famous Whirlpool Galaxy (M51), which lies at a distance of 23 million light years from our own Milky Way galaxy. Supernova explosions occur when the supply of fuel massive stars, stellar, completing the life cycle comes to an end, and the stars begin to collapse, turning eventually into a neutron star or black hole.
