Globular clusters function herbal laboratories for research of megastar formation and evolution as a result of they have a tendency to shape on the similar time from identical preliminary fabrics. But NGC 6325, some 26,000 light-years from Earth within the constellation Ophiuchus, is of pastime for a unique reason why. Studies have prompt some tightly packed globular clusters would possibly harbor intermediate-mass black holes that subtly impact the motions of surrounding stars. Astronomers are the usage of the Hubble Space Telescope’s Wide Field Camera 3 to review a bigger pattern of those dense clusters, together with NGC 6325, to search for extra proof of the unseen black holes that can be lurking at their cores.
