M28 - Globular Cluster

M28 is a globular cluster located in the constellation Sagittarius. It was discovered by Charles Messier in 1764. This cluster contains a significant number of variable stars and is known for its high star density.

M28 spans about 60 light-years across and contains tens of thousands of stars. The cluster is approximately 18,000 light-years away from Earth and has an apparent magnitude of 6.9, making it visible with binoculars or a small telescope.

M28 — Image Gallery

DSS Blue

M28 — blue-filter image
Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

M28 — red-filter image
Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

M28 — near-infrared image
Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite Image

M28 — composite color 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.
