The Whirlpool Galaxy was first discovered in 1773 by Charles Messier, who was charting the skies looking for objects that might be confused with comets. In 1845, astronomer William Parsons observed the galaxy pair with his telescope at Birr Castle, Ireland, and found the spiral structure of the Whirlpool.
Why is the Whirlpool Galaxy called the Whirlpool Galaxy?
The galaxy is nicknamed the Whirlpool because of its swirling structure. The Whirlpool’s most striking feature is its two curving arms, a hallmark of so-called grand-design spiral galaxies. Many spiral galaxies possess numerous, loosely shaped arms that make their spiral structure less pronounced.

Is there a planet in Whirlpool Galaxy?
It’s possible that a planet crossed in front of a black hole 28 million light-years away in the Whirlpool Galaxy. It’s drawing matter from a bright, massive companion star, material that heats up as it spirals inward. The planet briefly blocked the relatively small region of X-ray emission nearest the black hole.
