Scientists have recently discovered a “smoking gun” evidence of gravity using data collected by the European Space Agency’s (ESA) Gaia mission. This data has revealed that the gravity field of the Milky Way is not completely uniform—it is stronger in some directions than others, suggesting that gravity is the cause. The study, published in the journal Nature Astronomy, provides us with a better understanding of the structure of our galaxy and could help answer some of the most enduring questions in astronomy.

For years, astronomers have been trying to understand the structure of the Milky Way, but the mysterious force of gravity has, until now, been difficult to measure. Now, thanks to the data from ESA’s Gaia mission, scientists have discovered evidence of gravity in action. By analyzing the motion of stars across the Milky Way, the team was able to detect areas where gravity is stronger. This “smoking gun” evidence of gravity will allow us to better understand the structure of our galaxy and may even help us answer some of the most enduring questions in astronomy.
