This image from the Hubble Space Telescope shows a part of the sky known as the Extended Groth Strip (EGS). The CEERS Survey researchers will use the James Webb Space Telescope to observe the Extended Groth Strip in infrared light. Their observations employ three of the telescope’s instruments and will provide both images and spectra of the objects in the field — which includes at least 50,000 galaxies — helping to expand what we know about galaxies in the very early universe.

| Instrument | HST>ACS/WFC |
| Exposure Dates | June 2004 to March 2005 |
| Filters | F606W (V) and F814W (I) |
| About The Image | |
| Color Info | This image is a composite of many separate exposures made by the ACS instrument on the Hubble Space Telescope using two different filters to sample broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic image. In this case, the assigned colors are: Blue: F606W (V) Green: F606W (V) + F814W (I) Red: F814W (I) |
| 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 | |
