Summary
[edit]DescriptionMS 1455.0+2232.jpg |
English: These four galaxy clusters were part of a large survey of over 300 clusters used to investigate dark energy, the mysterious energy that is currently driving the accelerating expansion of the Universe. In these composite images, X-rays from Chandra (purple) have been combined with optical light from Hubble and Sloan Digital Sky Survey (red, green, and blue). Researchers used a novel technique that takes advantage of the observation that the outer reaches of galaxy clusters, the largest structures in the universe held together by gravity, show similarity in their X-ray emission profiles and sizes. |
