A Treasure Chest of Galaxies ✨

Our @NASAHubble Space Telescope captured this spectacular image showing spiral arms swirling in all colors and orientations, and fuzzy ellipticals speckled across the frame as softly glowing smudges on the sky.
Each visible speck of a galaxy is home to countless stars. A few stars closer to home shine brightly in the foreground, while a massive galaxy cluster nestles at the very center of the image — an immense collection of maybe thousands of galaxies, all held together by the relentless force of gravity.

Galaxy clusters, like the ones seen here by our NASA Hubble Space Telescope, are some of the most interesting objects in the cosmos. Their immense gravitational influence means they distort the space-time around them, causing them to act like giant zoom lenses. The light of background galaxies is warped and magnified as it passes through the galaxy cluster, allowing astronomers insight into the distant — and therefore early — universe.
