There's a very special year-end gift coming for us on December 21. After chasing each other through the sky for the better part of two decades, Jupiter and Saturn will finally cross paths on the day of the winter solstice. You won't even need a telescope to witness this rare celestial rendezvous – the two planets will appear to form a bright, elongated star visible to the naked eye. In what has been a long and bizarre year, you've got to forgive us for taking this as a sign from the heavens that things are going to be better in 2021. Here's the lowdown on how to observe the great conjunction this coming Monday.
