Hubble time! 🌌 Take a journey across 2.5 million light-years to the Andromeda galaxy (M31) in an animation based on real hubbleesa observations. At first glance, the Andromeda galaxy (M31) appears as a serene, glowing spindle of light. But look closer, and you’ll find a hidden cosmic ballet. The wide-angle view reveals 36 satellite galaxies orbiting Andromeda, each circled in yellow. What’s remarkable? They all move in the same direction, confined to a vast, thin plane—an arrangement that challenges our understanding of how galaxies form and interact. Thanks to Hubble, astronomers were able to map their positions in three-dimensional space, providing new insights into the structure of our cosmic neighbourhood. Swipe through to see close-up snapshots of some of these galaxies, including M32 (NGC 221)—a compact ellipsoidal galaxy thought to be the core remnant of a once-larger galaxy that collided with Andromeda billions of years ago. 🖥️ NASA, europeanspaceagency, Christian Niev...
