| About The Object | |
|---|---|
| Object Name | Hubble Ultra Deep Field, HUDF, and SN Primo |
| Object Description | Deep survey (color image) and Type Ia Supernova (greyscale images) |
| R.A. Position | 03h 32m 38.01s |
| Dec. Position | -27° 46' 39.08" |
| Constellation | Fornax |
| Distance | Redshift: z=1.55 |
| About The Data | |
| Data Description | These images were created from Hubble data from proposals (PI: S. Faber, University of California, Santa Cruz) and (PI: A. Riess (STScI/JHU). The lead author on the paper is S. Rodney (JHU). |
| Instrument | HST>ACS/WFC and HST>WFC3/IR |
| Exposure Dates | Data used in these images were taken in 2010 and 2011. |
| Filters | ACS/WFC: F435W (B), F606W (V), F775W (i), and F850LPW (z); WFC3/IR: F105W (Y), F125W (J), and F160W (H) |
| About The Image | |
| Color Info | This image is a composite of separate exposures acquired by the WFC3 and ACS instruments on HST. Several filters were used to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F435W (B) + F606W (V) Green: F775W (i) + F850LPW (z) Red: F105W (Y) + F125W (J) + F160W (H) |

| 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. |
