M13 - Great Hercules Cluster

The Great Hercules Cluster (M13) is a globular cluster located in the constellation Hercules. It was discovered by Edmond Halley in 1714 and included in Messier's catalog in 1764. M13 is one of the most prominent and well-known globular clusters in the northern hemisphere.

M13 spans about 145 light-years across and contains several hundred thousand stars. The cluster is approximately 22,200 light-years away from Earth and has an apparent magnitude of 5.8, making it visible to the naked eye under dark skies and easily seen with binoculars or a small telescope.

M13 — Image Gallery

DSS Blue

Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite Image

DSS color images combine blue, red and often near-infrared exposures into a composite view.

The images come from the Digitized Sky Survey 2 (DSS2), produced at the Space Telescope Science Institute (STScI) under contract with NASA, using data from UK Science and Technology Facilities Council (STFC), European Southern Observatory (ESO), National Geographic Society-Palomar Observatory Sky Survey (POSS II).
