The massive gravity of galaxy cluster MACS0647 acts as a cosmic lens to bend and magnify light from the more distant MACS0647-JD system. It also triply lensed the JD system, causing its image to appear in three separate locations. These images, which are highlighted with white boxes, are marked JD1, JD2, and JD3; zoomed-in views are shown in the panels at right. In this image from Webb’s Near Infrared Camera (NIRCam) instrument, blue was assigned to wavelengths of 1.15 and 1.5 microns (F115W, F150W), green to wavelengths of 2.0 and 2.77 microns (F200W, F277W) and red to wavelengths of 3.65 and 4.44 microns (F365W, F444W).

| About The Object | |
|---|---|
| Object Name | MACS J0647+7015, MACS0647-JD |
| Object Description | Galaxy Cluster/Gravitational Lens and z~11 Galaxy Candidate |
| R.A. Position | 06:47:50.00 |
| Dec. Position | +70:14:55.00 |
| Constellation | Camelopardalis |
| Distance | The distance to the cluster is 5.6 billion light-years (1.7 billion parsecs or redshift z = 0.591). The distance to the lensed source is about 13.3 billion light-years (4 billion parsecs or redshift z ~ 11). |
| About The Data | |
| Data Description | This image was created from JWST data from proposal: (D. Coe) |
| Instrument | NIRCam |
| Exposure Dates | 23 Sept 2022 |
| Filters | F115W, F150W, F200W, F277W, F356W, F444W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample different infrared wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F115W+F150W Green: F220W+F277W, Red: F356W+F444W |
| 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. |
