Facts about Sunflower Galaxy
- 08
Classified as an SAbc spiral galaxy, the Sunflower Galaxy belongs to the Canes Venatici I galaxy group along with the Whirlpool Galaxy.
- 07
M63 contains an active galactic nucleus powered by a supermassive black hole estimated at 30 million solar masses.
- 06
M63's spiral arms rotate at different speeds than its central bulge, a phenomenon called differential rotation that creates the galaxy's tightly wound structure.
- 05
Violent collisions with smaller galaxies shaped M63's structure, with evidence suggesting at least one major merger event occurred within the past billion years.
- 04
M63's distinctive spiral arms contain prominent dust lanes that give the Sunflower Galaxy its characteristic flower-like appearance when observed through telescopes.
- 03
Approximately 26 million light-years away, M63 was discovered by Pierre Méchain in 1779 and later catalogued by Charles Messier.
- 02
At magnitude 9.0, M63 remains invisible to the naked eye despite being one of the brightest spiral galaxies in the northern sky.
- 01
The Sunflower Galaxy spans approximately 220,000 light-years in diameter, making it twice as large as the Milky Way.
