MACS 0416 (Hubble + Webb Compass Image)

 MACS 0416 (Hubble + Webb Compass Image)

Image of galaxy cluster MACS0416 captured in visible light by Hubble’s ACS and WFC3 and in infrared light by Webb’s NIRCam, with compass arrows, scale bar, and color key for reference.

The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

The scale bar is labeled in arcminutes, which is an angle on the sky equivalent to one-60th of a degree. (The scale bar is half an arcminute long.) The full image is approximately 2.2 acrminutes across. 

This image shows visible and near-infrared wavelengths of light that have been translated into colors. The color key shows which Hubble ACS and WFC3 and Webb NIRCam filters were used when collecting the light. The color of each filter name is the visible light color used to represent the light that passes through that filter.

Exposure Dates HST: July 2012 - Feb 2023 JWST: 7 Oct 2022, 29 Dec 2022, 10 Feb 2022
Filters HST ACS: F435W, F606W, F814W; WFC3/IR: F105W, F125W, F140W, F160W; JWST NIRCam: F090W, F115W, F150W, F200W, F277W, F356W, F410M, F444W
About The Image
Color Info These images are a composite of separate exposures acquired by the Hubble and Webb Space Telescopes using the ACS, WFC3, and NIRCam instruments. Multiple filters were used to sample broad and narrow 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: Red: F444W and F410M, Orange: F356W, Yellow: F277W and F200W, Green: F160W, F150W, F140W, F125W, F115W, Cyan: F090W, F105W, F814W, Blue: F606W, F435W
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.
