Look at those two buddies. Just hanging out. Doing their thing. This starry pair offers a glimpse of what our Milky Way galaxy would look like to an outside observer. The edge-on galaxy is called NGC 4302, and the tilted galaxy is NGC 4298. Like twinning pals, both of these galaxies are approximately 55 million light-years away, reside in the constellation Coma Berenices, and were discovered together in 1784 by astronomer William Herschel. Although these galaxies look quite dissimilar from one another due to our perspective seeing them from different angles in the sky, they are very similar in structure and contents. Both galaxies are a little basic, as far as galaxies go. Being typical spiral galaxies, they have arms of young stars that wind outward from their centers. These bright arms are regions of intense star formation. Like other spiral galaxies, they have central bulges surrounded by a faint halo of stars and bars that extend from their central bulges to the arms. Who is you...
