The new three-dimensional map of the Milky Way shows two billion stars
At a press briefing by the European Space Agency in Germany, a new three-dimensional detailed map with 1.7 billion stars, including objects, the existence of which has not yet been known, was presented. The data for the map was collected for two years with a Gaia telescope.
Now we can say that humanity has the most accurate and detailed stellar map of the Milky Way.
“The data collected by Gaia predetermine the fundamentals of astronomy,” said Günther Hasinger, head of the ESA research department.
A new sky map is based on the first version, released in 2016 after a year of observation. The 2018 version has been greatly improved.
“The map can be called a huge step forward,” said one of the researchers, Anthony Brown, referring to past attempts to measure the distances and locations of stars in our galaxy.For example, the ESA Hipparcos telescope investigated only 118 thousand stars in more than 30 years of observations.
The new map includes data on the location of stars, their brightness, color and information about asteroids in our solar system. It even shows other galaxies that the telescope could “see”. Recently obtained data may allow scientists to learn more about dark matter.
Scientists will decipher information over the years. Most likely, humanity needs to be ready to reveal many secrets of our Universe.
