Ok, so it may be identified and it’s not flying but this nearly edge on barred spiral galaxy as seen through a telescope resembles the classic sci-fi UFO shape. It was graced with that name by the Astronaut Memorial Planetarium & Observatory (AMPO) in Cocoa, FL. Located roughly 20 million light years away in the constellation Lynx (Which by the way, was named not because it looked like a cat but because you need to have cat-like eyes to see the dim stars in it.) this beautiful structure gives us the opportunity to see key features that are difficult to resolve in a face-on or nearly face-on galaxy.

This angle gives us an opportunity to study the galactic bulge above and below the plane as well as the more than 300 globular star clusters that reside there. That’s about twice as many as are found in the Milky Way. You can also get a feel for just how thin the plane of the galaxy itself is; relatively paper thin in comparison to its massive width.

The classic galactic features are apparent here as well. Thick dust lanes mix throughout the blue spiral arms of relatively young stars. The nearer the core you get, the older and yellower the stars become where at its center a supermassive black hole resides.
