A research team led by Stefan Kraus and Gerd Weigelta the Max-Planck-Institute for Radio Astronomy (MPIfR) in Bonn (Germany) have succeeded using the telescopes of the VLT (Very Large Telescope) observatory with ESO (European South Observatory) to separate the dual system of youth star Theta Ori C, which is located in a stellar set which we call Orion's trapezium.
What actually works is perhaps best illustrated by the fact that until recently it was considered that this is a single star. Recent studies have shown, the computer data processing, as it was still a dual system. Only on Earth and in space no telescope that could definitely distinguish one star from another.
Astronomers are now four large telescopes of the VLT system successfully "forced" to work with interferometry as a single virtual telescope.

The resolution that was achieved was the order of 2 milli arc sec! The translation of the earthly way of measuring this would mean that we can discern the size of the subject vehicle on the moon. To achieve such a resolution telskopom he should have a mirror diameter of 130metara (if present in the universe, without the obstruction caused by the atmosphere) or 200metara even if it was located on Earth! The famous Hubble Space Telescope has a 2.5m diameter mirror only the largest telescopes Terrestrial - ten feet!
The telescope-interferometer involves simultaneous use of two or more telescopes that observe the same celestial object but were wide apart. Using their computer data is merged into a single information and photos obtained significantly higher resolution than is possible with a telescope.
Star system Theta 1 Ori lifelong bright young stars in real stellar delivery room, as astronomers like to say for the space of the Orion Nebula. Until now, that is 1300 light years away from us. Having obtained a clear picture of the position of these stars, and astronomers use triangulation methods are precisely determine their distance and it is now positioned on the value of 1350 light years. In this measurement, and helped mjernja made with VLBI (Very Long Baseline Array) radioastronomskog system.
Determined by computing how massive component has a mass 38 times greater than the mass of our Sun and the other is "only" nine times more massive than the Sun! Now on to more detailed study in terms of eventual discovery of concentrated protoplanetarnih disks around them.
According to Gerda Weigelta, these successes show just some opportunities that we in the future are available with the VLT telescopes of the European Southern Observatory (ESO). New discoveries and unheard preciznos measurements have become the reality of science fiction astronomers from several years ago!
Their importance in understanding the possibilities of the formation and evolution of multiple stellar systems, and computer-support theoretical models of astrophysicists.
