Hubble Space Telescope Spies Glittering Globular Cluster

This Hubble image shows NGC 6325, a globular cluster some 26,000 light-years away in the constellation of Ophiuchus. The color image includes both optical and near-infrared observations from Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS). Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

Using the NASA/ESA Hubble Space Telescope, astronomers have captured a striking new photo of the densely packed globular cluster NGC 6325. This Hubble image shows NGC 6325, a globular cluster some 26,000 light-years away in the constellation of Ophiuchus. The color image includes both optical and near-infrared observations from Hubble’s Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS).

Ongoing star formation processes as observed by VIRCAM/VISTA in the VISIONS program. The top panel shows L1688 in the Ophiuchus star-forming complex, depicting several dozen prominent young stellar objects located within one of the closest embedded clusters to Earth. The young stars are surrounded by a highly structured cloud composed of gas and dust that is largely being shaped by young, optically revealed hot stars in the vicinity. The bottom panels further highlight the complex morphology of the gaseous, dusty neighborhood of partly concealed young stars in the Ophiuchus molecular clouds L1709 and L1689.
