The European Space Agency published the most accurate counting of stars in the Milky Way and neighboring galaxies on Wednesday, offering astronomers plenty of new data for further research.

High-precision measurements of the distance, motion, brightness, and color of nearly 1.7 billion stars were collected by the Gaia spacecraft probe between July 2014 and May 2016.

Hundreds of scientists and software engineers took years to process the data and create a catalog of stars from which they could generate maps, including asteroids, solar system and even a three-dimensional map of some nearby stars.

Antonella Vallenari, one of the senior scientists involved in the project, said that astronomers have gained new insights into the life cycle of s.

ESA said that both professional and amateur astronomers could gain access to the data and look for new discoveries. It is the second release following the release of a smaller series of measurements over 2 million stars two years ago

More data is planned in the coming years.
