<pre>ESA presented the largest map of our galaxy in history

The European Space Agency has published the most detailed map of the location of the stars in our native galaxy, known as the Milky Way. The map has about 1.3 billion objects, with a total estimate of the number of stars in the galaxy of 300 billion. Immediately to calculate and record in the database all data is impossible – the Gaia project has been working for several years, and this is still intermediate, but very interesting results. [19659002] Gaia is a special space station launched in 2013. Its main task is to take high resolution images twice a year from all parts of star space. Since the station is a satellite of the Earth, and in six months our planet is displaced to a solid distance around the Sun, we get two pictures from different angles.

It remains to superimpose one on another to get the effect of binocularity and create a semblance of a three-dimensional image. Not for beauty sake – it's a way to more or less accurately measure the distance to the stars, to assess their relative location in space. The rest is the matter of technology, to make calculations and to record the location of objects in the map of the Milky Way.

According to Fred Jansen, the Gaia project manager, this is astronomy in its best format. The galactic map is laid out for universal access, free of charge. Scientists-astronomers can only take the coordinates of the stars and apply them in their studies.
