Facing NGC 6946

Explanation: From our vantage point in the Milky Way Galaxy, we see NGC 6946 face-on. The big, beautiful spiral galaxy is located just 10 million light-years away, behind a veil of foreground dust and stars in the high and far-off constellation of Cepheus. From the core outward, the galaxy's colors change from the yellowish light of old stars in the center to young blue star clusters and reddish star forming regions along the loose, fragmented spiral arms. NGC 6946 is also bright in infrared light and rich in gas and dust, exhibiting a high star birth and death rate. In fact, since the early 20th century at least nine supernovae, the death explosions of massive stars, were discovered in NGC 6946. In this deep color composite image, a small barred structure is just visible at the galaxy's core. Nearly 40,000 light-years across, NGC 6946 is also known as the Fireworks Galaxy.

Copyrighted images on the APOD website really annoy me, but this one is worthy of a link. If NASA is going to give free press and worldwide attention to some person who is selling his wares on his own site, the least that person can do is authorize hotlinking from the APOD image.

Their list of Messier Objects and NGC objects is fairly extensive, though, if you want a good online reference.

It won’t be ready until the 24 1/2 century. I heard a rumor that MicroSoft was developing it, so it will probably be around the 27 1/3 century before the patch is available.
