| About The Object | |
|---|---|
| Object Name | MACS J0717.5+3745 |
| Object Description | Cluster of Galaxies |
| R.A. Position | 07h 17m 33.79s |
| Dec. Position | 37° 45' 20.01" |
| Constellation | Auriga |
| Distance | 5.4 billion light-years or 1.7 billion parsecs |

| About The Data | |
| Data Description | Chandra Data: Chandra data used were from proposal . Hubble Data: The Hubble images were created from HST data from proposal : PI: Dr. H. Ebeling (University of Hawaii), I. Smail (University of Durham, UK), J.-P. Kneib (Laboratoire d'Astrophysique de Marseille, France), G. Smith (University of Birmingham, UK), and D. Donovan and E. Barrett (University of Hawaii). |
| Instrument | CXO>ACIS and HST>ACS/WFC |
| Exposure Dates | January 10, 2003 (CXO) and January 24, 2005 - February 9, 2005 (HST) |
| Filters | ACS: F606W (V) and F814W (I) ACIS Energies: 5 - 25 T(keV) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the ACS instrument on the Hubble Space Telescope and the ACIS instrument onboard the Chandra X-ray Observatory. Two filters were used to sample broad wavelength ranges. A continuous energy band was used to sample the X-ray data. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Cyan: F606W (V) Yellow: F814W (I) Blue - Violet (temperature map): 5 - 25 T(keV) |
