Space News: What's up for December 2024

What’s up for December? Venus, Jupiter, and Mars shine brightly; the stars of winter and their pointy little friend; and "Meteors, meet the Moon."
Starting off with the planets, Venus is hard to miss in the southwest after sunset — it's that dazzling bright "evening star." You’ll find it getting a bit higher in the sky each evening through the month.
Saturn is visible toward the south beginning at nightfall. Look for it to track a bit farther to the west as the weeks go by.
Meanwhile, Jupiter reaches opposition on Dec. 7, meaning it’s at its brightest for the year and visible all night long. You’ll find it rising in the east-northeast as darkness falls, among the stars of the constellation Taurus.
Mid-month, around Dec. 14, watch for Jupiter sitting between the nearly full Moon and Taurus's brightest star, orange-colored Aldebaran.
Next, Mars will also be putting on its own show, doubling its brightness during December as it heads toward its own opposition in January.
Early in the month, it rises about four hours after dark, but by New Year’s Eve, it’s rising just about 90 minutes after sunset — always shining with its distinctive reddish hue.
And on Dec. 17, you’ll find the Red Planet super close to the Moon, which will be just two days past its full phase.
The stars of winter are making their grand entrance in December. As evening falls, you’ll see the mighty hunter Orion rising in the east, with Taurus the bull above it, and the stars of the twins in Gemini to their left.
These constellations host some wonderful sights — like the Crab Nebula and Pleiades star cluster in Taurus and the misty Orion Nebula, which hangs below Orion's belt. If you look to the western sky soon after dark, you can still spot the three bright stars of the Summer Triangle getting quite low on the horizon. But as they depart, three bright stars of winter bring their own prominent triangular shape to mark the season.
Once you spot Orion's distinctive belt of three stars, you’re well on your way to finding what we call the Winter Triangle. Just follow the belt stars to the left and slightly downward — they point right to Sirius, the brightest star in the night sky. Then look upward and to the left of Sirius to spot Procyon, and back up toward Orion to find reddish Betelgeuse at its shoulder. These three bright stars form an equilateral triangle that’s visible throughout the season.
The Geminid meteor shower peaks after midnight in the early morning of Dec. 14, and they’re usually one of the best meteor showers of the year under good conditions.
This year, the nearly full Moon will wash out the fainter meteors on the peak night. Still, the Geminids are known for bright meteors, and it’s common to spot their shooting stars up to a week before the peak.
If you’re up before dawn that week, it’s worth looking up, just in case you spot a speck of dust from space streaking through the morning sky.
