Astronomers have unveiled the most detailed 3D map of the Milky Way yet, which could shed new light on the galaxy and the universe beyond.
The Gaia observatory of the European Space Agency has been observing the universe since 2013.
The map contains enough new detail that astronomers can now measure the acceleration of the solar system and calculate the mass of the galaxy.
The information will fill in some unknown gaps in our knowledge of what is happening in space.
“The Gaia spacecraft is circling the sky continuously and it is making many, many passes over the sky and it is measuring the position and brightness of the stars and with this, it creates an extremely precise frame of reference that is basically transmitted to the Earth through radio signals and we put them together in the computer, “Professor Gunther Hasinger, science director of the European Space Agency in Spain, told Euronews.
“What we are learning is basically the history of our Milky Way,” he added.
“We are delving into the history of time, more or as archaeologists do, but many billions of years, even before the sun was born, so we can say something about the fate of the Milky Way when it was very young. . and it can also predict what will happen in the future. “
