Messier 100 (also known as NGC 4321 or the Mirror Galaxy) is a grand design intermediate spiral galaxy in the southern part of the mildly northern Coma Berenices. [5] It is one of the brightest and largest galaxies in the Virgo Cluster and is approximately 55 million light-years [3] from our galaxy, about 166,000 light-years in diameter.

2024年8月25日 · M100 is a stunning example of a grand-design spiral galaxy. This detailed Hubble image reveals individual stars within the galaxy’s prominent spiral arms. These dusty structures swirl around the galaxy’s nucleus and are marked by a flurry of star formation.

2015年8月28日 · Messier 100 (M100) is a grand design spiral galaxy located in the Virgo Cluster, in the constellation Coma Berenices. The galaxy lies at an approximate distance of 55 million light years from Earth and has an apparent magnitude of 10.1. Its designation in the New General Catalogue is NGC 4321.

Messier 100 is one of the brightest and largest galaxies in the Virgo cluster, about 55 million light-years away, with a diameter of 160,000 light years. [2] It was discovered by Pierre Méchain in 1781. Later it was entered in Messier’s catalogue of nebulae and star clusters after Charles Messier made observations of his own a month later.

2018年12月10日 · This stunning spiral galaxy is Messier 100 in the constellation Coma Berenices, captured here by the NASA/ESA Hubble Space Telescope — not for the first time. Among Hubble’s most striking images of Messier 100 are a pair taken just over a month apart, before and after Servicing Mission 1, which took place 25 years ago in December 1993.

2012年8月15日 · The galaxy Messier 100, or M100, shows its swirling spiral in this infrared image from NASA's Spitzer Space Telescope. The arcing spiral arms of dust and gas that harbor star forming regions glow vividly when seen in the infrared.

Messier 100 (M100) is a grand design spiral galaxy situated in the northern constellation Coma Berenices. First discovered by French astronomer Pierre M?chain on March 15, 1781, it was subsequently included in the catalogue of deep sky objects by Charles Messier, his colleague.

These dusty structures swirl around the galaxy’s nucleus, and are marked by a flurry of star formation activity that dots Messier 100 with bright blue, high-mass stars. This image from the NASA/ESA Hubble Space Telescope, the most detailed made to date, shows the bright core of the galaxy and the innermost parts of its spiral arms.

Messier 100 or M100 (also designated NGC 4321) is a spiral galaxy in the constellation Coma Berenices. It has an apparent visual magnitude of 9.3 and its angular diameter is 7x6 arc-minutes. M100 lies at an estimated distance of 60 million light years.
