In the Large Magellanic Cloud galaxy is a star-forming region that has puzzled astronomers around the world for years. It is called the Tarantula Nebula and it is an object so luminous that, if it were at the same distance from Earth as the Orion Nebula, it would even cast shadows on our planet. This luminosity is due to the presence of four supermassive stars of enormous dimensions that were discovered in 2010 by a team of researchers.
The Chilean VISTA (Visible and Infrared Survey Telescope for Astronomy) telescope, measuring 4.1 meters and located at the Paranal Observatory of the European Southern Observatory (ESO) in Chile, has delighted us with the images of the tens of thousands of stars clustered in Messier 55, the oldest in the Universe. Discover them in this video.
A spectrometer designed by astronomers at the University of California (USA) will allow scientists to study the first galaxies that formed in the Universe.
Although until now they were only known in the shape of a disk, ellipse or irregular, an international team of astronomers has just found a rectangular galaxy with a shape that resembles emerald-cut diamonds, according to its discoverers. Leda 074886 is not easy to see, since it is 70 million light years from Earth and also has 50 fewer stars than the Milky Way.
Planets outnumber stars in the Milky Way, according to an astronomical study published today in the journal Nature. The existence of planets around stars is "a rule, rather than an exception," said the study's lead author, Arnaud Cassan, of the Institute for Astrophysics in Paris, France.
A peculiar gamma ray burst (GRB) that took place in space on Christmas Day 2010 could be caused by the merger of two stars, a neutron star and a giant star, after a stage in the who shared wrapping.
In the Milky Way, half of the stars have a traveling companion with whom they form a binary system. There are even those that form stellar "trios". Why then are there lonely stars? Scientists at the University of Bonn and the Max-Planck Institute for Radio Astronomy in Germany have concluded that stars are normally born two at a time within clouds of gas and dust, and that those traveling alone lost somewhere moment to his companion.
