Esta es una vista del telescopio espacial Hubble de una porción de bienes-sur, el campo sur de un gran estudio de cielo profundo realizado por varios observatorios para rastrear la formación y evolución de las galaxias. La imagen muestra un rico tapiz de 7.500 galaxias que se extienden a través de la mayor parte de la historia del universo. Las galaxias más lejanas, algunas de las manchas rojas muy débiles, son vistas ya que aparecieron hace más de 13 mil millones de años, o aproximadamente 650 millones de años después del Big Bang. Pronto, el telescopio espacial James Webb retrocedirá aún más en este campo para rastrear la formación y evolución de las primeras galaxias.

| About The Object | |
|---|---|
| Object Name | GOODS-S/ERS, GOODS South Field WFC3 Early Release Science Data (GOODS-S WFC3 ERS), Chandra Deep Field South (CDF-S) |
| Object Description | Cosmological Survey |
| R.A. Position | 03h 32m 40.23s |
| Dec. Position | -27° 43' 9.86" |
| Constellation | Fornax |
| Dimensions | This image is approximately 9.68 arcminutes wide by 4.27 arcminutes high. |
| 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. |
