Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth.

Jul 6, 2014 · Messier 106 (M106) is a spiral galaxy located in the northern constellation Canes Venatici. The galaxy lies at a distance of 22 to 25 million light years from Earth. It has the designation NGC 4258 in the New General Catalogue.

Aug 9, 2024 · This collage features three views of Messier 106, also known as NGC 4258. The first two images show the target in visible light as seen by KPNO and the NASA/ESA Hubble Space Telescope. The image on the right is a new image from the NASA/ESA/CSA James Webb Space Telescope in the infrared.

These images are a composite of separate exposures acquired by the WFC3 and ACS instruments on the Hubble Space Telescope. Several filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter.

Aug 12, 2022 · As the megamasers are known to originate in the black hole accretion disk of NGC 4258, the authors explain the evenly spaced peaks as the result of periodic magnetorotational instabilities (MRI)...

Jul 4, 2018 · The supermassive black hole at the center of NGC 4258 is about ten times larger than the one in the Milky Way, and is also consuming material at a faster rate, potentially increasing its impact...

Jan 11, 1995 · The tremendous concentration of mass, equivalent to 40 million suns, in the center of the galaxy NGC4258 in the constellation Canes Venatici, was revealed by the apparent rotation of a molecular disk that surrounds it.

NGC 4258 . This shows the X-ray contours from an HRI observation of the Seyfert 2 nucleus which resides in the spiral galaxy NGC4258. The contours from this active nucleus are overlaid on radio and optical images of the source, illustrating the coincidence of extended emission regions in several bandpasses.
