Jupiter is preparing to pass Saturn, an event known as a great conjunction. On Dec. 21, the two planets will come closer to each other than they’ve been in nearly 400 years — and it will be visible to the naked eye.

The moon will align with Mars, Saturn and Jupiter in the pre-dawn hours this week.

Apollo 13’s astronauts never gave a thought to their mission number as they blasted off for the moon 50 years ago. Even when their oxygen tank ruptured two days later — on April 13.

There hasn’t been a whole lot of good news in 2020, but here’s something to get excited about: Tuesday’s supermoon will be the closest the full moon gets to Earth in 2020, meaning it will look bigger and brighter than any other full moon this year.
