This is Not a Photo of the Milky Way. It’s the Map of 1.8 Billion Stars From Gaia’s Major New Data Release | Universe Today

Since the mission began, the ESA has issued three early releases of Gaia data, each of which has led to new research findings and more detailed maps of our galaxy. Based on the third release of mission data, known as Early Data Release 3 (Gaia EDR3), astronomers have created a map of the entire sky that includes updated data on celestial objects and manages to capture the total brightness and color of stars in our galaxy… More about this article in the link below…
