At a go off star discovered disk of debris and dust

Herschel Space Observatory of the European Space Agency released the first pictures of the belt of dust - formed as a result of collisions of asteroids or comets - orbiting star-subgiant, which is located around the planetary system.

After a few billion years, during which the stars stably maintained hydrogen is burning stars like our sun, draining internal resources and

Astronomers have cataloged galaxy collisions

Collisions between galaxies, it is a fairly common phenomenon. Almost all of the galaxies involved in one or More collisions during its existence. One example can provide as our Milky Way galaxy, is sent to the Andromeda galaxy, our nearest galactic neighbor, at about 50 kilometers per second to run into her in about a billion years.

A group of researchers from the Harvard-Smithsonian Center for Astrophysics used the results of the latest observations of 31 interacting galaxies located in fourteen systems to carry out the first systematic analysis of the distribution of energy in the interacting galaxies over a wide spectral range.

Scientists have resolute the age of Saturn's rings

Saturn's rings are almost the same age of the Sun. The wrapping up was made ​​by the American astrophysicist new photographs, sent to Earth the spacecraft Cassini.

After analyzing the data collected by the probe, the researchers came to the conclusion that water ice, from which mainly consist of the ring and,
