Scientists release most detailed star chart of Milky Way

Scientists release most detailed star chart of Milky Way

The map contains 1.7 billion stars "for which we can tell where they are in the sky with very high accuracy, and how bright they are", said Anthony Brown of the Gaia Data Processing and Analysis Consortium.

The new data release, which covers the 22 months between July 2014 and May 2016, pins down the positions of almost 1.7 billion stars, and with much greater precision, as well as 14,000 asteroids.

One can get to see the exact positions, colors, motions, and brightness of those 1.3 billion stars of our Milky Way in the 3D map.

This new data release is even more robust, covering another 22 months of observation time.

Launched in 2013, Gaia gathers data on about 100,000 stars per minute - some 500 million measurements per day. On 25 April it released its second batch of data.

Gaia also has locked on to the positions of more than half a million quasars - extremely remote celestial objects, emitting exceptionally large amounts of energy, powered by black holes a billion times as massive as our sun.

"We did not know if it was going to be nice but it's really wonderful", said Brown, while he presented the blue and red sky map based on information about the temperature of millions of stars, clouds of dust, and gas. Because this process is so straightforward, these stars are used as "standard candles" to measure distances to other astrophysical objects. In the UV range shows that in the blue is removed the stars from our Solar system, and the red of the approaching stars.

"This catalog is the most precise, most complete catalog that has ever been produced". Gaia mainly focused on measuring the positions and distances of stars with unprecedented precision. Its first map was published in September 2016, with about 1.15 billion stars. The scientists were eagerly waiting for its observations so that they can understand our Milky Way and its objects in a better way.

Astronomers will be busy for years working with Gaia's data, which can give us clues to the formation and evolution of the Milky Way. It may also help us pin down how fast the universe is expanding.
