This striking representation of the Messier 19 (M19) globular cluster combines Hubble observations in ultraviolet, visible, and near-infrared light spectrums, revealing a brilliant celestial sight. A small gap in the Hubble data (horizontal line towards the center right) is seamlessly filled with findings from the ground-based Victor M. Blanco 4-meter Telescope. This Hubble project's objective was to delve into M19's formation and the distribution of diverse star populations within the cluster.
Discovered by Charles Messier in 1764, M19 lies 28,500 light-years away from Earth in the Ophiuchus constellation. This stunning star cluster is most easily visible during July, boasting an apparent magnitude of 7.7. Amateur astronomers can detect M19 using binoculars, where it appears as a faint patch of light. In contrast, large telescopes enable a clear view of M19's individual stars.
Image Description: "A mesmerizing array of orange, red, yellow, blue, and white stars fill the field, creating a spherical, dense mass that gradually dissipates towards the image's edges on a black backdrop."
**Globular clusters like M19** are known for their spherical shape, as stars within them orbit a shared center of gravity. However, some clusters, including M19, exhibit a slightly elongated form. Positioned a mere 6,500 light-years from the Milky Way's center, M19 is subject to the gravitational pull and tidal forces from the colossal galactic core, potentially causing its stretched appearance.
With this captivating view of the Messier 19 globular cluster, astronomy enthusiasts can gain deeper insight into the fascinating world of celestial formations and the diverse populations of stars that inhabit them.
