According to Ukrinform, this was stated in a press release from ESA.

The Gaia mission was launched to create the most accurate and complete multidimensional map of the Milky Way. This allows astronomers to reconstruct our galaxy’s structure and billions of years of evolution, and to better understand the life cycle of stars and our place in the universe.

It was noted that the published data includes new and improved details of about two billion stars in the galaxy, as well as new information such as chemical composition, stellar temperatures, colors, masses, age and the speed of stars towards or away from Earth. our planet.

The new data includes, for example, special subgroups of stars that change their brightness over time.

Also new to this dataset are the largest catalog of binary stars, thousands of solar system objects such as asteroids and planetary moons, and millions of galaxies and quasars outside the Milky Way.

At ESA, “One of the most surprising discoveries made based on new data is that Gaia can detect ‘stellar flickers’ – tiny movements on the surface of stars that change the shape of stars.

As Ukrinform reports, the European Space Agency’s (ESA) spacecraft Mars Express photographed a crater located in the Aonia Terra region in the southern highlands of Mars.
