As the winter nights unfold, the sky offers a spectacular view for stargazers. This December, take advantage of the moonless evenings to explore fainter celestial wonders!
On December 20, set your sights on the elusive 12th-magnitude Comet 333P/LINEAR. Nestled in the northern constellation of Cygnus, it’s positioned quite close to the star Kappa Cygni. You can also discover the nearby open cluster NGC 6939 and the spiral galaxy NGC 6946; both are accessible just northeast of the comet. For the best viewing experience, check these targets early, just as twilight descends.
As we transition into the winter solstice on December 21 at 4:21 A.M. EST, a new season begins. Early risers can catch a stunning sight in the southeastern sky, where Mercury and the red giant star Antares will shine brightly, with Mercury emerging triumphantly above Antares during dawn.
The following day, December 22, holds the peak of the Ursid meteor shower. Look for meteors radiating from a point northwest of Kochab, the brightest star in Ursa Minor. Despite a modest rate of visibility, the radiant’s northern position guarantees a night full of potential shooting stars.
Finally, December 23 showcases the grandeur of Jupiter, particularly its moons and distinct cloud bands. This giant planet remains a beacon of beauty in the evening sky, promising an unmissable show for observers!
