The emblematic rings of the gigantic gaseous planet Saturn, as well as those less known of the gigantic Neptune and Uranus are made of pieces of raw material derived from all the planets like Pluto that remained for too long in the vicinity of these planets, being destroyed by the strong gravitational attraction developed by them, according to a new study. Astronomers believe … [Read more...]
The ‘rebirth’ of a star: a phenomenon observed by astronomers in the sky, for the first time
An international astronomers team observed for the first time the warming and the cooling steps during the 'rebirth' of a star - SAO 244567, a star situated at about 2.700 light years from the Terra. The researchers will have to do additional calculations to explain the behavior of the star. Normally, the 'rebirth' process of a star produces in a way too long period to be … [Read more...]
Over one billion stars were localized in the Milky Way
We use to say that is impossible to count the stars on the sky. Still, a map of the Milky Way that has an unprecedented precision and that localized 1.142 million of stars starting from the observations of the European Telescope Gaia, was presented by the ESA (The European Space Agency). Anthony Brown, member of the Gaia researching team, stated in a press conference in Madrid … [Read more...]
The sudden disappearance of a very far star may confirm the theories about the creation of the black hole
The astrophysicists have no certitude about the way in which the black holes take form. The sudden disappearance of a gigantic red star, that was studied by astronomers through the orbital telescope Hubble and it was at a distance of about 20 million light years, can represent the first birth of a black hole 'witnessed' by humanity, according to newscientist.com. Using the data … [Read more...]
