Gaia to shed new light on Milky Way Galaxy, asteroids, stars and more today! Watch it LIVE online, know when and where
New data will be released by the European Space Agency (ESA) from its Milky Way Galaxy-charting Gaia mission on Monday June 13. "Join European Space Agency and Gaia mission representatives on Monday 13 June for a preview of the third major data release. This world-class treasure trove is set to reveal new insights into our Solar System, our Milky Way galaxy, asteroids and our wider cosmic neighbourhood," ESA said in a release. It can be known that the event can be watched live on ES Web TV from 8:00-9:00 UTC (10:00-11:00 CEST) that is 1:30PM -2:30PM IST.
Explaining what Gaia is, ESA said, "Gaia is ESA’s mission to create the most accurate and complete multi-dimensional map of the Milky Way. This allows astronomers to reconstruct our home galaxy’s past and future evolution over billions of years, better understand the lifecycle of stars, and our place in the Universe."

Since Gaia launched in 2013, data sets were released in 2016 and 2018 and a subset of the third data set in 2020. These data releases contained stellar positions, distances, motions across the sky, and colour information, among others.
Gaia will release its third full data set today, which will contain yet more and improved information about almost 2 billion objects in the Milky Way, mostly stars, and a subset of Solar System objects and extragalactic sources. These data were collected between 25 July 2014 and 28 May 2017.
New in this data set are spectra for a significant number of objects, which can be used to determine accurate luminosities, temperatures, masses, and chemical compositions. This release also includes radial velocities for 33 million stars, a five time increase as
