Tonight – April 12, 2016 – look for the moon and Winter Circle stars. It’s difficult to convey the humongous size of the Winter Circle, this lasso of brilliant stars that fills our western sky at dusk and nightfall. But you can see the circular pattern of stars around the moon tonight.
The Winter Circle stars aren’t the brightest star-like object in the sky on these April, 2016 evenings. Instead, the brightest “star” in the evening sky is actually the planet Jupiter. The king planet will be hard to miss, because Jupiter ranks as fourth-brightest celestial body to light up the heavens, respectively, after the sun, moon and the planet Venus. But throughout April of 2016, Venus will sit in the glare of the rising sun and will not be all that easy to catch before sunrise (especially in the Northern Hemisphere).
The Winter Circle can be seen from the Southern Hemisphere, as well. If you’re in that part of the world, the star Sirius will appear at the top of the Circle and the star Capella at the bottom (if you can see Capella at all; it’s far to the north on the sky’s dome), as shown on the chart above.
No matter where you live worldwide, observe the Winter Circle at dusk/nightfall because the Winter Circle stars that loom low at nightfall will sink below the horizon by early evening.
Bottom line: Use the moon on April 12, 2016, to find the bright stars of the Winter Circle!
