It turned out that the observatory is also capable of recording starquakes (yes, these also happen).
European Space Agency (ESA) reportedthat the Gaia Telescope has returned to Earth the third data set containing new information and more detailed details about nearly two billion stars in our galaxy.
The resulting catalog offers different types of data, including chemical composition, stellar temperature, color, mass, age, and the speed at which stars approach or move away from the Earth (radiation speed). Much of this information has been revealed through spectroscopy, the separation of starlight into its component colors.
The new data set also offers the largest catalog of binary stars, thousands of solar objects. systems, including asteroids and satellites, as well as millions of galaxies and quasars outside the Milky Ways.
One of the most surprising discoveries made from the new data is that Gaia is able to detect starquakes - tiny movements on the surface of a star that change their shape of stars, for which the observatory did not initially was intended.
Starquakes allow us to learn more about the stars - and especially about their inner workings. With its unexpected abilities, Gaia will be a goldmine for studying the asteroseismology of massive stars.
