This image shows a region of space containing a sample of dwarf galaxies studied by NASA's Hubble Space Telescope. Hiding among these thousands of galaxies are faint dwarf galaxies (marked by the red circles) that resided in the early universe, between 2 and 6 billion years after the big bang, an important time period when most of the stars in the universe were formed. Some of these galaxies are undergoing a ferociously fast rate of star formation called "starbursts." Astronomers are striving to deduce the galaxies' contribution to star formation in this crucial era of the universe's history. The image is part of the Great Observatories Origins Deep Survey (GOODS).

| 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. |
