APOD 4.2

This picture, "NGC:4561 The Umbrella Galaxy" is very pleasing to the eye when one first beholds it. It is particularly applicable to class of late, due to the fact that it is a galaxy, which we have been studying of late. We even did an exercise where we identified galaxies, and I would identify this galaxy as a tightly wound spiral galaxy with many arms. It is also quite interesting, because it deals with a constellation which we will be studying soon, Coma Bernices. It is interesting in that the galaxy,as the name would suggest, has an 'umbrella' around it which baffles many Astronomers. While perusing the relevant links, I learned that this umbrella is actually a collection of tidal star streams.
