The Sky Today on Saturday, July 12: M56 in Lyra

Already high in the east an hour after sunset is the constellation Lyra the Lyre, easy to locate thanks to its brightest star, magnitude 0 Vega. Tonight, we’re looking southeast of this star at M56, an 8th-magnitude globular cluster in near the border of Lyra and Cygnus. In fact, one of the easiest ways toContinue reading "The Sky Today on Saturday, July 12: M56 in Lyra"

Michael’s Miscellany: The Eyes Have It

I thought I’d write a bit about several eye-related topics. First up is resolution, which is the ability to see details in objects.

July 11, 1801: Jean-Louis Pons finds his first comet

On July 11, 1801, French astronomer Jean-Louis Pons made his first comet discovery, c/1801 N1. When he’d began his career in 1789 as a doorkeeper (essentially, a concierge) at Marseille Observatory, the directors had recognized his talents and taught him more about astronomy. That background, combined with his exceptional observational skills and the ability toContinue reading "July 11, 1801: Jean-Louis Pons finds his first comet"
