This is a gallery of the Hubble Space Telescope Frontier Fields. The top six panels are massive galaxy clusters that act as huge lenses in space, magnifying and stretching images of remote galaxies behind each cluster that are too faint for Hubble to see directly. While one of the telescope’s cameras looked at each cluster of galaxies, another camera simultaneously viewed an adjacent patch of sky. This second region is called a "parallel field" — a seemingly sparse portion of sky that provides a deep look into the early universe. Astronomers observed each of the six clusters and six parallel fields in both near-infrared and visible light. This allowed scientists to create more detailed, overlapping, and complete images.

| 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. |
| About The Data | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
| Filters | The camera filters that were used in the science observations. |
| About The Image | |
| Image Credit | The primary individuals and institutions responsible for the content. |
| Publication Date | The date and time the release content became public. |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
| Orientation | The rotation of the image on the sky with respect to the north pole of the celestial sphere. |
