Sky Highlights for December 2023
December is a month filled with exciting celestial events and highlights in the night sky. Whether You are in the Northern or Southern Hemisphere, there are plenty of astronomical phenomena to enjoy. In this article, we will explore the key highlights for skywatchers in December and provide tips on how to make the most of these celestial events.
The Night Sky in the Northern Hemisphere
As darkness falls, take a moment to appreciate the dark Dust Lane of the Great Rift and the fuzzy brightness of the Milky Way in the western sky. The beauty of the night sky is Never-ending, and even in December, you can still enjoy the wonders it has to offer. Look out for Ursa Major, the Big Bear, low on the northern horizon in the evening. As the night progresses, Ursa Major climbs higher into the northeast, revealing its majestic presence.
The Winter Circle
One of the most captivating asterisms in the night sky is the Winter Circle. An asterism is a well-known pattern in the stars that is not one of the official constellations. The Winter Circle, or winter hexagon, is composed of six of the brightest stars from different constellations. Look out for Canis Minor, Pollox of Gemini, Capella of Auriga, Aldebaran of Taurus, Rigel of Orion, and the brightest star in the night sky, Sirius. In a dark rural area, you may also be able to spot a faint strip of the Milky Way running through the middle of the circle.
The Southern Summer Circle
For skywatchers in the Southern Hemisphere, the Winter Circle is known as the Southern Summer Circle. It can be found in the eastern sky as darkness falls. However, unlike in the Northern Hemisphere, the Southern Summer Circle arches much higher and crosses the northern sky from right to left. If you wait until late evening, you can capture a breathtaking Milky Way Arch Panorama facing east, with the Southern Summer Circle on the left and southern hemisphere constellations like Vela and Crux on the right. Take AdVantage of the region of the Milky Way in the south, which is bright and fuzzy, studded with the brightest stars in the southern hemisphere night sky.
The Geminid Meteor Shower
One of the most highly anticipated astronomical events of December is the Geminid meteor shower. Considered the best meteor shower of the year, it promises a dazzling display of shooting stars. This year, conditions are favorable as there is only a 2% one-day-old Crescent Moon, which will set shortly after sunset, leaving the skies dark all night. The Geminids are active from November 19th to December 24th, but the peak falls on December 14th at approximately 19:30 Universal Time.
Rates and Timing
During the peak, observers in completely dark rural areas may see up to 100 meteors per hour. However, those in the southern hemisphere should expect lower rates. The radiant point, where the meteors appear to originate, is within the constellation Gemini, which starts the night in the east and climbs to its highest point around 2 a.m. local time. It's important to note that you don't have to look directly at the radiant point; meteors will fall all over the sky. Simply Trace a line backwards along the meteor's path, and they will all point to the same point in the night sky.
Viewing Tips
To make the most of your Geminid meteor shower experience, make sure you find a dark location with clear skies. Avoid areas with heavy light pollution. Dress warmly and bring blankets or a reclining chair for comfort. It's advisable to lie down and keep your eyes adjusted to the darkness for at least 20 minutes to allow your vision to adapt fully. Patience is key when watching meteor showers, so relax and enjoy the show. Don't forget to make a wish on every shooting star!
Unique Astronomical Events
December brings some unique astronomical events as well. One intriguing event is the sighting of an astronaut's lost tool bag in space. On November 1st, NASA astronauts Jasmine Mbil and Laurel Oara misplaced a toolbox during a maintenance Space Walk on the International Space Station. The toolbox is now in orbit around Earth and can potentially be spotted from certain locations. Use an app like ISS Detector to see if there are any ISS passes in your area, and look for the toolbox following the same path.
Another interesting event involves the star Betelgeuse in the constellation Orion. This variable star, known for its regular dimming and brightening, may fade or disappear temporarily due to asteroid Leona passing in front of it, obstructing some of its light. Observers along a narrow path in southern Europe and across the Atlantic Ocean into the Bahamas, southern Florida, and parts of Mexico may witness this event.
Saturn, Jupiter, and Venus in December
December also offers opportunities to observe various planets in the night sky. Saturn can be found in Aquarius, shining at a modest magnitude of 0.9. For observers in the northern hemisphere, Saturn starts the night in the south and sinks into the west. In contrast, for those in the southern hemisphere, Saturn can be found high overhead as darkness falls and later sinks down to the west.
Jupiter continues to shine brightly this month in the constellation Aries. It follows Saturn across the sky and can be seen starting the night in the southeast, arching across the south (northern hemisphere), or climbing high overhead in the northern skies (southern hemisphere). Additionally, Jupiter ends its retrograde motion on the 30th, marking a significant event in its celestial motion.
Venus, the dazzling morning star, rises in the east in the pre-dawn hours. With a magnitude of -4.1, it is impossible to miss. On the 9th, a thin crescent moon joins Venus, creating a stunning celestial pairing. Venus's brilliance illuminates the early morning sky and adds a touch of magic.
The Cold Full Moon on Boxing Day
December 26th brings the cold full moon, named for the chilly winter season. Falling just a day after Christmas, this full moon is also known as the Boxing Day moon in commonwealth countries. It's a perfect opportunity to step outside and admire the beauty of the moon above. Capture its serene glow or simply bask in its ethereal light.
Wittens Photography Competition Winners
Lastly, we celebrate the winners of the Wittens photography competition. This month's theme was "The Great Rift," a part of the Milky Way that extends above the horizon. In third place, Luke wowed us with a stunning image of old castle ruins in Scotland, expertly capturing the Great Rift. Patrick secured Second place with a mesmerizing shot of an old stone building in Hungary, showcasing the warm yellow light against the cold night. Finally, Lucas claimed first place with a breathtaking image from the Czech Republic, demonstrating layers of depth and stunning composition. Congratulations to all the winners!
Conclusion
December is a month packed with celestial wonders. From the Geminid meteor shower to the beauty of the Winter Circle and the majesty of the planets, there is something for every sky enthusiast. Remember to mark your calendars, find dark sky locations, and dress warmly for your stargazing adventures. Enjoy the magic and wonder of the night sky, and may clear skies and awe-inspiring sights accompany you throughout the month.
