To the Milky Way’s Anticenter and Beyond: Gaia’s New Detailed Data From More Than 1.8 Billion Stars – SciTechDaily
The motion of stars in the outskirts of our galaxy hints at significant changes in the history of the Milky Way. This and other equally fascinating results come…

Gaia’s stellar motion for the next 400 thousand years. The stars are in constant motion. To the human eye this movement – known as proper motion – is imperceptible, but Gaia is measuring it with more and more precision. The trails on this image show how 40,000 stars, all located within 100 parsecs (326 light years) of the Solar System, will move across the sky in the next 400 thousand years. These proper motions are released as part of the Gaia Early Data Release 3 (Gaia EDR3). They are twice as…
