An international team of astronomers has created a directory enclose more than 84 million stars in the Milky Way. The basis for this proposal is a huge picture of the size of nine gigapixel, which amounted to an infrared VISTA telescope data Chilean observatory.
Image of stars the size is nine meters long and seven meters wide.
Roberto Saito, the lead researcher of the Pontifical Catholic University of Chile considers that this work will help to better understand the formation and evolution of spiral galaxies.
The observation of the stars is a challenge. They need to learn in the infrared part of the spectrum, as it is less susceptible to interference of cosmic dust.
Researchers have found a large number of red dwarfs, small and relatively cool stars, around which may have planets.
