Look for the beautiful Northern Crown in May
Tonight, look for a constellation that’s easy to see on the sky’s dome, if your sky is dark enough. Corona Borealis – aka the Northern Crown – is exciting to find. It’s an almost-perfect semicircle of stars. You’ll find this beautiful pattern in the evening sky from now until October.
You’ll need a fairly dark sky to see Corona Borealis between Vega and Arcturus. It’s a semicircle of stars and very noticeable.
The brightest star in Corona Borealis is Alphecca, also known as Gemma, sometimes called the Pearl of the Crown. The name Alphecca originated with a description of Corona Borealis as the “broken one,” in reference to the fact that these stars appear in a semicircle, rather than a full circle. Alphecca is a blue-white star, with an intrinsic luminosity some 60 times that of our sun. It’s located about 75 light-years from Earth.
Bottom line: Look for Corona Borealis – the Northern Crown – between the brilliant stars Arcturus and Vega tonight! This constellation is very noticeable, if you have a dark sky.
