M20 - Trifid Nebula

The Trifid Nebula (M20) is an emission nebula located in the constellation Sagittarius. It was discovered by Charles Messier in 1764. The nebula is named for its three-lobed appearance, caused by dark dust lanes that divide the nebula into three parts.

M20 spans about 21 light-years across and is illuminated by a group of hot, young stars. The nebula is approximately 5,200 light-years away from Earth and has an apparent magnitude of 6.3, making it visible with binoculars or a small telescope.

M20 — Image Gallery

DSS Blue

M20 — blue-filter image
Blue images highlight younger, hotter stars that emit strongly at blue wavelengths.

DSS Red

M20 — red-filter image
Red images reveal older, cooler stars and emission nebulae glowing strongly in hydrogen-alpha light.

DSS Near-Infrared

M20 — near-infrared image
Near-infrared images penetrate dust that obscures visible light and reveal hidden structures.

DSS Composite Image

M20 — 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.
