The shower peaked late last week, but, with all the comet excitement going on, people didn’t start submitting their best Geminid images until the weekend.
You need an alarm clock and a clear sky to the east, the sunrise direction. Binoculars will come in handy. The 2 bright planets will come closer and closer, finally closest on December 21. Beautiful!
On December 21, NASA’s Juno spacecraft will make its 16th science pass over the cloud tops of Jupiter, marking the halfway point in the solar-powered spacecraft’s prime mission.
A south tropical disturbance has just passed Jupiter's iconic Great Red Spot and is captured stealing threads of orange haze from the Great Red Spot in this series of color-enhanced images from NASA's Juno spacecraft. From left to right, this sequence of images was taken between 2:57 a.m. and 3:36 a.m. PDT (5:57 a.m. and 6:36 a.m. EDT) on April 1, 2018, as the spacecraft performed its 12th close flyby of Jupiter.

This year’s report shows that the Arctic region experienced the 2nd-warmest air temperatures ever recorded, the 2nd-lowest overall sea-ice coverage, and lowest recorded winter ice in the Bering Sea.
NASA's Operation Icebridge captured this image of the town of Narsaq in Greenland in April, 2018.
Astronomers have discovered that a Neptune-sized exoplanet – HAT-P-11b – has an even larger helium atmosphere than first thought. The atmosphere is literally inflated like a massive balloon.

Comet 46P/Wirtanen is making one of the 10 closest comet flybys of Earth in 70 years today. Whether you glimpse it with the eye – or see it online – don’t miss this comet! Charts, tips and other info here.
Greg Hogan in Kathleen, Georgia caught Comet Wirtanen on February 26, 2018. He wrote: "This comet was FINALLY over my tree line of my neighborhood. Here is a shot I got with my 85mm lens on a Canon 7D. I was able to find it quickly with just a quick shot pointed in the right direction. Taken 9:30pm EST." Canon 7D, 85mm, 5-sec exposure, ISO 6400, f2.8.
Sun pillars, or light pillars, are shafts of light extending from the sun or other bright light sources. They’re caused by ice crystals drifting in Earth’s air.
Michael Busch captured this pair of photos on December 12, 2018 and wrote: "Incredible sun pillar above and then below the sun. Fire Island, New York."
December solstice 2018 arrives on December 21 at 22:23 UTC. High summer for the Southern Hemisphere. For the Northern Hemisphere, the return of more sunlight!
Researchers have created tiny droplets of the ultra-hot matter that once filled the early universe, forming 3 distinct shapes and sizes: circles, ellipses and triangles
