Galaxy Cluster RDCS 1252.9-2927
This image captures a massive cluster of galaxies called RDCS 1252.9-2927. This galaxy cluster existed when the universe was only 5 billion years old, or about 35 percent of its present age.
The field was imaged by Hubble during proposal 9290: H. Ford (JHU), M. Postman (STScI), M. Franx (University of Leiden), J. Blakeslee (JHU) and P. Rosati (ESO). The science team presenting the science results on this object includes J. Blakeslee (JHU), M. Franx (Leiden Observatory), M. Postman (JHU/STScI), P. Rosati (ESO), B. P. Holden (UCO/Lick), G. D. Illingworth (UCO/Lick), H. C. Ford (JHU), N. J. G. Cross (JHU), C. Gronwall (JHU), N. Benítez (JHU), R. J. Bouwens (JHU), T. J. Broadhurst (Hebrew University), M. Clampin (STScI), R. Demarco (ESO), D. A. Golimowski (JHU), G. F. Hartig (STScI), L. Infante (Pontificia Universidad Catolica de Chile), A. R. Martel (JHU), G. K. Miley (Leiden Observatory), F. Menanteau (JHU), G. R. Meurer (JHU), M. Sirianni (JHU) and R. L. White (JHU/STScI).
