Whirlpool Galaxy: A Perfect Spiral in Space

The Whirlpool Galaxy (M51) is one of the best examples of a grand-design spiral galaxy.
It lies about 27 million light-years away in the constellation Canes Venatici.
Its spiral arms are strikingly symmetrical, lined with bright young stars and star-forming regions.
The Whirlpool is interacting with a smaller companion galaxy, NGC 5195.
This cosmic dance enhances its spiral structure, fueling bursts of star formation.
The galaxy spans about 76,000 light-years—smaller than the Milky Way but dazzlingly detailed.
Dust lanes weave through its arms, giving depth and contrast to its appearance.
The Whirlpool has a central supermassive black hole, as most galaxies do.
It was the first galaxy identified as spiral by William Parsons in 1845.
Its picture-perfect shape makes it one of the most photographed galaxies in the night sky.
