The central region of M51 appears to be undergoing a period of enhanced star formation. The present efficiency of star formation, defined as the ratio of mass of new stars to the mass of star-forming gas, is only ~1%, quite comparable to the global …

2024年8月25日 · 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.

The Whirlpool has a supermassive black hole at its heart, thanks to the merging of M51 with its neighboring galaxy, NGC 5195. The Whirlpool Galaxy’s fascinating structure gives astronomers a better understanding of how galaxies interact with each other and how stars form within them.

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.

2024年2月22日 · The Whirlpool Galaxy M51 (NGC 5194) The Whirlpool Galaxy, also known as M51 or NGC 5194, is a stunning spiral galaxy located approximately 23 million light-years away from Earth. It is one of the most famous galaxies in the night sky, and is often used as a benchmark for studying spiral galaxies.

2023年8月29日 · M51 — also known as NGC 5194 — lies about 27 million light-years away from Earth in the constellation Canes Venatici, and is trapped in a tumultuous relationship with its near neighbour, the dwarf galaxy NGC 5195. The interaction between these two galaxies has made these galactic neighbours one of the better-studied galaxy pairs in the night sky.

1996年4月24日 · The Whirlpool Galaxy (M51) Parents Generations of Stars in Its Center. The NASA/ESA Hubble Space Telescope has snapped a view of several star generations in the central region of the Whirlpool Galaxy (M51), a spiral region 23 million light-years from Earth in the constellation Canes Venatici (the Hunting Dogs). The galaxy's massive center, the...

2023年10月2日 · Galaxy Messier 51 (M51, also designated NGC 5194) is nicknamed the Whirlpool because of its prominent swirling structure. Its two curving arms, a hallmark of so-called grand-design spiral galaxies, are home to young stars, while its …

The spiral arms in M51, like those of our own galaxy, are sites of active star formation, where bright blue clusters of young stars ionize gas clouds like our own familiar Orion Nebula. The pink-red glowing regions corresponding to emission nebulae seen in long-exposure images of the galaxy are known as H-II regions; the bluer star clouds are ...

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.
