This is a montage of four small, young galaxies taken from a Hubble Space Telescope Wide Field Camera 3 slitless grism sample of 28 low-mass galaxies located 10 billion light-years away in the Hubble Ultra Deep Field region of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS). These color images were generated from exposures in six different Hubble filters and provide detailed information about the different wavelengths of light coming from the galaxies. Astronomers say this new study gives them a view of galaxies as they appeared when the universe was less than a quarter of its current age and shows that central black holes formed at an early stage in galaxy evolution.

| 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. |
