NGC 6366 Click image for full size version June 13, 2026 Meet NGC 6366, one of more than 150 globular clusters orbit the Milky Way's core. Each is a more-or-less spherical grouping of hundreds of thousands of stars tightly held together by gravity. Some, like M13 are big, bright, tightly packed and spectacular. Others... not so [...]

NGC 5053

Ron Brecher — Sun, 01 Jun 2025 16:22:13 +0000

NGC 5053 Click image for full size version June 1, 2025 NGC 5053 tends to be ignored by imagers and observers alike, including me until about 2015, because of its surroundings: NGC 5053 lies near a much brighter, richer globular cluster, M53. NGC 5053 contains only a few thousand stars, so it lacks the dense [...]
