Abell Galaxy Cluster


“When I first saw the Hubble image of this galaxy, I knew right away that it was unusual,” Marc Postman of the Space Telescope Science Institute said of the monster elliptical galaxy, with a central core bigger than any seen before embracing a mystery never seen before. “The core was very diffuse and very large. The challenge was then to make sense of all the data, given what we knew from previous Hubble observations, and come up with a plausible explanation for the intriguing nature of this particular galaxy.”
