1992年6月8日 · Hubble Space Telescope provides a detailed look at the core of the giant spiral galaxy M51. These images, taken at different wavelengths of light, reveal complex structure and detail in the galaxy's core, which is thought to hide a massive black hole.

The Whirlpool Galaxy Galaxy (M51), is an interacting grand-design spiral galaxy in the constellation Canes Venatici. It is estimated to be 23 million light-years away. The Whirlpool Galaxy is located at the coordinates RA 13h 29m 53s | Dec +47° 11′ 43″.

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.

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.

2023年8月29日 · The graceful winding arms of the grand-design spiral galaxy M51 stretch across this image from the NASA/ESA/CSA James Webb Space Telescope. Unlike the menagerie of weird and wonderful spiral galaxies with ragged or disrupted spiral arms, grand-design spiral galaxies boast prominent, well-developed spiral arms like the ones showcased in this image.

This sharpest-ever image, taken in January 2005 with the Advanced Camera for Surveys aboard the NASA/ESA Hubble Space Telescope, illustrates a spiral galaxy's grand design, from its curving spiral arms, where young stars reside, to its yellowish central core, a home of older stars. The galaxy is nicknamed the Whirlpool because of its swirling ...

2015年6月3日 · The galaxy’s bright core appears more defined in 8-inch instruments, which also reveal the galaxy’s large halo and a hint of the dark dust lanes and spiral arms. M51’s smaller companion galaxy, NGC 5195, is also visible, but the bridge connecting the two can only be detected in larger instruments.

2 天之前 · M51 is my last galaxy from the clear spell that we had in early March. 1 hour integration of 10s subs. The 12" is delivering some good details and the short exposures have probably helped to get details very close to the core. Skywatcher 300P flextube goto, adi …

The core of the main galaxy appears bright and stellar. It is worth trying several eyepiece focal lengths to find out at which magnification the spiral arms best stand out against the dark sky background.
