Researchers at Cornell University are taking a new approach to the search for alien life: looking for habitable planets older than Earth, […]

Hubble and Chandra Unveil Mysteries Concerning Dark Matter

From HubbleSite: “This collage shows images of six different galaxy clusters taken with NASA’s Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total. Using visible-light images from Hubble, […]
