This is a Hubble Space Telescope view of a portion of GOODS-South, the southern field of a large deep-sky study by several observatories to trace the formation and evolution of galaxies. The image shows a rich tapestry of 7,500 galaxies stretching back through most of the universe's history. The farthest galaxies, a few of the very faint red specks, are seen as they appeared more than 13 billion years ago, or roughly 650 million years after the Big Bang. Soon, the James Webb Space Telescope will peer back even farther into this field to trace the formation and evolution of the very first galaxies.

| About The Data | |
| Data Description | The image was created from Hubble WFC3 data from proposal , R. O'Connell (University of Virginia) and collaborators, combined with the HST/ACS , which includes data from proposals and , P.I. M. Giavalisco; , P.I. Saul Perlmutter; , , and , P.I. A. Riess. |
| Instrument | HST>ACS/WFC, HST>WFC3/UVIS, and HST>WFC3/IR |
| Exposure Dates | Sept. 2002 - Dec. 2004, Exposure Time: 96 orbits (ACS) and Sept. 6, 2009 - Oct. 11, 2009, Exposure Time: 104 orbits (WFC3) |
| Filters | WFC3/IR: F098M, F125W, and F160W ACS/WFC: F435W, F606W, F775W, and F850LP WFC3/UVIS: F225W, F275W, and F336W |
| About The Image | |
| Color Info | The image is a composite of separate exposures made by the WFC3 and ACS instruments on the Hubble Space Telescope. In total, 10 filters were used to sample a very wide wavelength range. The color results from assigning different hues (colors) to combinations of the monochromatic images. In this case, the assigned colors are: Red: WFC3/IR F125W + F160W Green: ACS/WFC F606W + F775W + F850LP + WFC3/IR F098M Blue: WFC3/UVIS F225W + F275W + F336W + ACS/WFC F435W |
| 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. |
