Globular Cluster M92 (NIRCam Image)

A rectangular image oriented horizontally appears to be two separate square images with a wide black gap in between. Both squares are filled with blue, white, yellow, and red points of light of different size and brightness, most of which are stars. Altogether, the stars appear to form a loose ball-like shape whose core is obscured by the gap .

Image of the globular cluster Messier 92 (M92) captured by the James Webb Space Telescope’s NIRCam instrument. The black strip in the center is a chip gap, the result of the separation between NIRCam’s two long-wavelength detectors. The gap covers the dense center of the cluster, which is too bright to capture at the same time as the fainter, less dense outskirts of the cluster. 

This image is a composite of four exposures using four different filters: F090W (0.9 microns in wavelength) is shown in blue; F150W (1.5 microns) in cyan; F277W (2.77 microns) in yellow; and F444W (4.44 microns) in red. 

The image is about 5 arcminutes (39 light-years) across.

About the Object

  • R.A. Position
    R.A. PositionRight ascension – analogous to longitude – is one component of an object's position.
    17:17:07.39
  • Dec. Position
    Dec. PositionDeclination – analogous to latitude – is one component of an object's position.
    +43:08:09.4
  • Constellation
    ConstellationOne of 88 recognized regions of the celestial sphere in which the object appears.
    Hercules
  • Distance
    DistanceThe 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.
    26700
  • Dimensions
    DimensionsThe physical size of the object or the apparent angle it subtends on the sky.
    Image is about 5 arcminutes across (39 lightyears).

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

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 specific 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: F090W, Cyan: F150W, Yellow: F277W, Red: F444W
