The event was expected by thousands of scientists around the world who daily “delve” into data from the telescope put into orbit by the European Space Agency (ESA) in 2013.
After its launch, “Gaia” worked on the creation of the largest and most precise three-dimensional space catalog in history, transmits BTA.
The Gaia telescope is located 1.5 million kilometers from Earth against the direction of the Sun to better protect against its radiation. Protected from the effects of micrometeorites, its two optics move slowly in space, performing a full turnover in six hours.
“ Gaia” detects and observes a very small part of the stars in our galaxy, which has a diameter of 100,000 light years, and beyond. Although its focus is mainly focused on the stars, the telescope's catalogue includes multiple celestial objects. They range from all known varieties of stars, exoplanets and asteroids, to the interstellar environment and galactic clouds near the Milky Way.
Thanks to the observations of the Gaia Telescope, scientists can better understand the phenomena of formation and evolution of stars and our galaxy.
The first catalogue of “Gaia” was presented in 2016. It was only thanks to the second of 2018, involving 1.7 billion celestial objects, that scientists found, for example, that our Milky Way galaxy merged with its “sister” 10 billion years ago. The third catalogue presented today is the most complete yet with its 1.8 billion celestial objects.
"Gaia” caused a revolution in knowledge,” says Catherine Tyuron, an astronomer from the Paris Observatory.
"Discoveries will multiply,” notes Chantal Panam of the National Space Research Center, adding that after the release of the second catalogue, data from the Gaia telescope was used in about 3800 scientific publications.
The end of the Gaia mission is planned for 2025 The final space catalogue won't be ready until 2028
Space Telescope has drawn a map of over 1.8bn Milky Way stars
The European Gaia Space Telescope presented the first part of a catalogue of more than 1.8 billion celestial objects from the Milky Way galaxy, observed with unparalleled accuracy, France Press reported.tags:
