Explanation: Beautiful island universe Messier 94 lies a mere 15 million light-years distant in the northern constellation of the hunting dogs, Canes Venatici. A popular target for earth-based astronomers, the face-on spiral galaxy is about 30,000 light-years across, with spiral arms sweeping through the outskirts of its broad disk. But this Hubble Space Telescope field of view spans about 7,000 light-years or so across M94's central region. The sharp close-up examines the galaxy's compact, bright nucleus and prominent inner dust lanes, surrounded by a remarkable bluish ring of young, massive stars. The massive stars in the ring appear to be less than about 10 million years old, indicating the galaxy experienced a corresponding well-defined era of rapid star formation. As a result, while the small, bright nucleus is typical of the Seyfert class of active galaxies, M94 is also known as a starburst galaxy. Because M94 is relatively nearby, astronomers can explore in detail reasons for the galaxy's burst of star formation.

“Starburst” Galaxy is great, but if galaxy M51 wasn’t already called the “Whirlpool” Galaxy, I could certainly see M94 getting it.

The name could have been stolen long before recorded history on Earth.

Except that you're just seeing the core in that picture. Overall it looks more like a bullseye because something probably collided with it, resulting in the starburst.

OK, wow, it’s been a lot of years since I’ve seen it. I wouldn’t be able to see it like THAT, obviously. Thanks.
