Explanation: What could cause the center of M94 to be so bright? Spiral galaxy M94 has a ring of newly formed stars surrounding its nucleus, giving it not only an unusual appearance but also a strong interior glow. A leading progenitor hypothesis holds that an elongated knot of stars known as a bar rotates in M94 and has generated a burst of star formation in the inner ring. Recent observations have revealed the outer, fainter ring is not closed and relatively complex. M94, pictured here spans about 30,000 light years, lies about 15 million light years away, and can be seen with a small telescope toward the constellation of the Hunting Dogs (Canes Venatici).

“M94, pictured here spans about 30,000 light years, lies about 15 million light years away”
Again, for those who don’t know, a “light year”, the DISTANCE light travels in a year at its speed of 186,000 miles/second works out to about 5.9 TRILLION miles. In short, 15 MILLION light years is a long friggin way from here!

Also, star color is like the colors of the flame on a gas stove. Blue is the hottest. Orange and yellow cooler (respectively). All stars may seem white at first glance, but if you look closely and compare, you should notice that some are more blue, orange, or yellow than others. This has solely to do with their surface temps. The Sun, a yellow star, has a surface temp of around 6,000 C.

One of my favorite objects! Easy to find (even in the small city) and quite bright.
Worth taking a look in your small scope.

That’s beautiful and most unusual, too. Great APOD, Mr. Civilizations.
I very much appreciate your posts and pings.
Thank you, and oops! I forgot to wish you a happy birthday.
Happy belated birthday, my friend. Hope you had a nice celebration on the day.
