The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. [6] [7] [8] It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. [9]

2024年8月25日 · Also known as the Whirlpool Galaxy, Messier 51's spiral arms are star-forming factories. The Whirlpool Galaxy, M51, is a spiral galaxy located 31 million light-years away. It highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of star clusters.

It was observed and cataloged by famous astronomer Charles Messier in 1773 as Messier 51 (M51). It eventually earned the nickname “The Whirlpool” because it resembles a vortex in the water. M51’s companion galaxy (NGC 5195) is clearly visible in photographs, and even detectable through the telescope eyepiece (with enough aperture).

2015年6月3日 · Messier 51 (M51), better known as the Whirlpool Galaxy, is a famous grand-design spiral galaxy located in the constellation Canes Venatici. The Whirlpool Galaxy has an apparent magnitude of 8.4 and lies at an approximate distance of 23 million light years from Earth. It has the designation NGC 5194 in the New General Catalogue.

The graceful, winding arms of the majestic spiral galaxy M51 (NGC 5194) appear like a grand spiral staircase sweeping through space. They are actually long lanes of stars and gas laced with dust.

One of the most famous and recognizable galaxies in our night sky, the Whirlpool Galaxy or Messier 51 (M51), has long been a focus for astronomers worldwide. Located within the Canes Venatici constellation, M51 showcases an extraordinary example of a grand-design spiral galaxy.

2023年8月8日 · Hubble Messier 51 (M51) The Whirlpool Galaxy is a spiral galaxy located 31 million light-years away. Also known as M51, it highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of …

The Whirlpool Galaxy, also known as Messier 51 (M51) and NGC 5194, is a grand-design spiral galaxy in Canes Venatici. The galaxy appears face-on when seen from Earth. Its designation in the New General Catalogue is NGC 5194. The galaxy lies about 23 million light years from Earth. It was named the Whirlpool because of its swirling spiral structure.

Then, just slide your telescope a little south and west and you might find this stunning pair of interacting galaxies, the 51st entry in Charles Messier famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194.

Messier 51 or M51 (also designated NGC 5194/5) is a spiral galaxy in the constellation Canes Venatici. It has an apparent visual magnitude of 8.4 and its angular diameter is 11x7 arc-minutes. M51 lies at an estimated distance of 37 million light years.
