ESA’s XMM-Newton space telescope allowed to study a remarkable gamma-ray burst whose source was labeled as GRB130925A, in a galaxy about 5.6 billion light years from Earth. This gamma-ray burst was originated by a blue supergiant star, a very massive star that is rare today but was probably very common in the early universe.
The Hubble Space Telescope has photographed an extraordinary structure 100,000 light years long containing clusters of young stars that form a sort of bridge around the nuclei of two ancient galaxies within the galaxy cluster known as SDSS J1531 +3414. This unique structure may provide new clues about the formation of star clusters as a result of galaxies mergers.
Astronomical research are getting us used to really bizarre discoveries and sometimes astronomers can truly say they found a jewel in space. In the past, the analysis of the planet 55 Cancri e led to theorize that part of it is a huge diamond, now a team of astronomers has identified a white dwarf that may have turned into a diamond the size of the Earth.
NASA’s Solar Dynamics Observatory (SDO) space probe has discovered a square-shaped coronal hole in the Sun’s corona, the outer part of the atmosphere of our star. It’s far south on the Sun so it’s unlikely that the solar wind originated in that area reaches Earth.
A team of researchers led by astronomer Ivan Ramirez of the University of Texas at Austin has identified the first Sun “sibling”. This star, identified as HD 162 826, almost certainly formed over 4.5 billion years ago in the same gas cloud in which the Sun formed along with thousands of other stars. The methods used to find it will help discover more of their “siblings” and also to understand in which part of the galaxy they formed.
