M38 - Open Cluster

M38 is an open cluster located in the constellation Auriga. It was discovered by Giovanni Battista Hodierna before 1654 and independently by Charles Messier in 1764. The cluster contains a mix of young, hot stars and older stars.

M38 spans about 25 light-years across and contains around 100 stars. The cluster is approximately 4,200 light-years away from Earth and has an apparent magnitude of 7.4, making it visible with binoculars or a small telescope.

M38 — Image Gallery

DSS Blue

M38 — blue-filter image
Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

M38 — red-filter image
Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

M38 — near-infrared image
Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite Image

M38 — 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.
