Makarov (Russian Academy of Sciences, Special Astrophysical Observatory). The science team comprises: K. McQuinn and E. Skillman (University of Minnesota, Minneapolis), J. Cannon (Macalester College, MN), J. Dalcanton (University of Washington, Seattle), A. Dolphin (Raytheon Company), and D. Stark and D. Weisz (University of Minnesota, Minneapolis). |
| Instrument | HST>ACS |
| Exposure Dates | January 18, 2004, Exposure Time: 35 minutes |
| Filters | F606W (R) and F814W (I) |
| About The Image | |
| Color Info | These images are composites of several separate exposures made by the ACS instrument on the Hubble Space Telescope. Two filters were used to sample broad wavelength ranges for each image. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are orange/yellow for the I-band (F814W) and cyan/blue for the wide V-band (F606W) filter. The images have been further adjusted so the colors more closely resemble their true visual appearance, particularly the red hydrogen emission of the star-forming regions. Cyan: F606W (R) Yellow: F814W (I) |

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
