It provided the latest update of the catalog thanks to the data collected by the space telescope XMM-Newton European Space Agency. The result of the analysis of about 7,500 observations of XMM-Newton satellite, is the richest atlas of the sky in X-rays ever obtained from a single mission. There are 565 962 X-ray sources in

The missing link of stellar explosions

© Afrim Constantin –

Observations in the radio band have identified a sort of intermediate supernova that is halfway between an ordinary supernova and a gamma-ray burst. This is an important result which provides new clues about the mechanism that lies behind these phenomena violent and explosive and that determines their physical properties. The results were published in the

A survey conducted by the Subaru telescope reveals an unexpected level of abundance of chemical elements heavier than hydrogen and helium in the gas that consists of two galaxies in the universe remote clusters. Two clusters of primordial galaxies, at about eleven billion light years from us, have been studied by a team of researchers

Galaxies in a coma can come back to life. If there is a fusion of galaxy clusters that generates a shock wave capable of generating a new season of star formation. The galaxies are grouped often in clusters, and many are close to us but have stopped forming stars in the distant past. An international

Thanks to the use of public data, provided by the Virtual Observatory, two Russian astronomers have found that the compact elliptical galaxies may have been expelled from their clusters are formed and where they once lived. The researchers believe that their discovery could shed light on the structure and evolution of this class of objects.

For some time there was talk of this mysterious black hole found at the center of the galaxy 30 million light from us. The researchers come with new confirmations and future observations that will be able to understand more about the birth of galaxies in the early Universe. In 2011: the galaxy Henize 2-10 hides

New record set at flash emission

© Afrim Constantin –

The observations of NASA’s Swift satellite have seized a great flash of emission from the head of the class of Supergiant Fast X-ray Transients, during which this source has exceeded 10 times their own personal record of brightness, and even the theoretical maximum limit brightness expected for these sources. This result, obtained by a team
