Hubble Space Telescope
There’s more to the universe than meets the eye! 👀
Here’s a look at a galaxy group in light humans can’t see - infrared and X-ray - as well as optical light. We’re seeing it as it appeared when the universe was 6.5 billion years old, a little less than half its current age. More than half of the galaxies in our universe belong to galaxy groups like the one pictured here. Studying galaxy groups is critical for understanding how individual galaxies link up to form galaxy clusters, the largest gravitationally bound structures in the universe.
This image combines infrared data from Webb with infrared and optical observations from @NASAHubble. The data from @NASAChandraXray and ESA’s XMM-Newton, shown in purple, shows where X-rays are emitted by hot gas in the group of galaxies. The second image shows just the Hubble and Webb data.

Image description: An area of deep space with thousands of galaxies in various shapes and sizes on a black background. A few gold-colored galaxies are bunched closely together in the center. A large, translucent purple cloud lies over the galaxies, thickest across the center where the gold galaxies sit, and fainter up to the right. This shows where X-rays are emitted by hot gas in the group of galaxies. The second image is the same image without the purple X-ray data.
