| About The Object | |
|---|---|
| Object Name | NGC 3982 |
| Object Description | Face-on Spiral Galaxy |
| R.A. Position | 11h 56m 28.13s |
| Dec. Position | 55° 7' 30.86" |
| Constellation | Ursa Major |
| Distance | 68 million light-years (26 million parsecs) |
| About The Data | |
| Data Description | The image was created from Hubble data from proposals and : A. Riess (STScI) et al.; : L. Ho (Carniegie Institute of Washington) et al.; and : A. Saha (NOAO/AURA) et al. |
| Instrument | HST>WFPC2, HST>ACS/WFC, and HST>WFC3 |
| Exposure Dates | March 2000 - August 2009, Exposure Time: 25.5 hours |
| Filters | F555W (V), F658N (H-alpha+[N II]), and F814W (I) |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the WFPC2, ACS, and WFC3 instruments on the Hubble Space Telescope. Three filters were used to sample broad and narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue/cyan: F555W (V) Red: F658N (H-alpha+[N II]) Red/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. |
