At left, the quasar SDSS J165202.64+172852.3 is highlighted in a Hubble Space Telescope image taken in visible and near-infrared light. The images on the right and at bottom present new observations from the James Webb Space Telescope in multiple wavelengths. They demonstrate the distribution and motions of gas within a newly observed galaxy cluster around the central quasar.
The image at right is composed of four narrow-band images made from the Webb NIRSpec instrument’s integral-field spectroscopy mode. All four of the narrow-band images show light from doubly ionized oxygen atoms.
The panels at the bottom present the four narrow-band images separately. Each color illustrates the relative speed of ionized oxygen gas across the galaxy cluster. The redder the color the faster the gas is moving away from our line of sight relative to the quasar, while the bluer the color the faster it's moving toward us relative to the quasar. The color green indicates that the gas is steady in our line of sight in comparison to the quasar.

| 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. |
