M25 - Open Cluster

M25 is an open cluster located in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745 and later included in Messier's catalog in 1764. The cluster contains a mix of young, hot stars and older stars.

M25 spans about 19 light-years across and contains around 86 stars. The cluster is approximately 2,000 light-years away from Earth and has an apparent magnitude of 4.6, making it visible to the naked eye and easily seen with binoculars or a small telescope.

M25 — 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).

Special thanks to National Optical Astronomy Observatory (NOAO), Royal Observatory, Edinburgh, California Institute of Technology for their significant contributions.
