Messier 101
Big spiral galaxy M101 is one of the last entries in Charles Messier's famous catalog, but definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way.

A new Chandra study shows that there are 1,075 stars within 4 light-years of the center of the Westerlund 1 star cluster. To get a sense of how crowded this is, 4 light-years is about the distance between the Sun and the next closest star to Earth! by @chandraxray
