M105 - Elliptical Galaxy

M105 is an elliptical galaxy located in the constellation Leo. It was discovered by Pierre Méchain in 1781 and later cataloged by Charles Messier. M105 is known for its bright core and lack of spiral arms.

M105 spans about 55,000 light-years across and contains a massive population of old stars. The galaxy is approximately 36 million light-years away from Earth and has an apparent magnitude of 10.2, making it visible with a small telescope.

M105 — 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.
