Astronomy Picture of the Day - A Volcanic Great Conjunction

Explanation: Where can I see the Great Conjunction? Near where the Sun just set. Directionally, this close passing of Jupiter and Saturn will be toward the southwest. Since the planetary pair, the Sun, and the Earth are nearly in a geometric straight line, the planets will be seen to set just where the Sun had set -- from every location on Earth. When can I see the Great Conjunction? Just after sunset. Since the two planets are so near the Sun directionally, they always appear in the sky near the Sun, but can best be seen when the Earth blocks the Sun but not the planets: sunset. Soon thereafter, Jupiter and Saturn will also set, so don't be late! Is tomorrow night the only night that I can see the Great Conjunction? Tomorrow night the jovian giants will appear the closest, but on any night over the next few days they will appear unusually close. Technically, the closest pass happens on 21 December at 18:20 UTC. Will there be an erupting volcano on the horizon near the Great Conjunction? Yes, for example if you live in Guatemala where the featured image was taken. Otherwise, generally, no. In the featured image captured last week, Jupiter and Saturn are visible toward the right, just above a tree, and bathed in the diffuse glow of zodiacal light.

Can you help explain what happens tonight? Saturn and Jupiter align. The moon is at 50%. And all other facts.

Cats and dogs cuddling. Liberals and conservatives kissing each others butts. Same O, Same O.

Tonight Jupiter and Saturn are as closely aligned as they will get. After tonight they will move apart every night until they are only above the horizon during day time. Not sure the exact dates, but Jupiter and Saturn will be visible again before sunrise, but no longer closely aligned. Not sure about the moon phase, not really following that in reation to the planet alignment. Jupiter and Saturn should be above the place where the sun sets.
