After targeting primarily galaxies recently, I decided to check out a globular cluster last evening. Messier 53 lies about 63,000 light years from us and, according to astronomers, is approaching at 70 km/sec. That translates to a whopping 156,492 miles/hour. Given the current distance and speed, Earth should have a close encounter in about 275 million years with this beautiful cluster.
