The observation – among the very first science observations undertaken by Webb – is part of Early Release Science (ERS) program 1334, one of 13 ERS programs designed to help astronomers understand how to use Webb and make the most of its scientific capabilities. On June 20, 2022, the James Webb Space Telescope spent just over one hour staring at Messier 92 (M92), a globular cluster 27,000 light-years away in the Milky Way halo. Pagan (STScI).Įditor’s Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process. Download the full-resolution image of M92 from the Resource Gallery at the Space Telescope Science Institute. The image is about 5 arcminutes (39 light-years) across. 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. The black strip in the center is a chip gap, the result of the separation between NIRCam’s two long-wavelength detectors. This image is composite of four exposures using four different filters: F090W (0.9 microns) is shown in blue F150W (1.5 microns) in cyan F277W (2.77 microns) in yellow and F444W (4.44 microns) in red.
