On Monday night, Saturn and Jupiter will pass within 0.1 degrees of each other in our night sky creating a visual effect of a single "Christmas star". Here's a good article showing exactly how rare this is (Christmas Star

It looks like it's going to be cloudy down here in south Texas, but you guys up north should definitely step outside and check it out. It will be in the southwestern sky from sunset to 7:30pm. Here's a picture I took last night from my rooftop in the middle of San Antonio. You can actually see Jupiter's moons just to the upper left of it.
