If you looked at the sky last night, you likely saw you could see a star that was brighter than all of the others – except it wasn't a star.
It was actually two planets that were closely aligned, called a conjunction.
Take a look. You can see the that Jupiter and Saturn appear next to each other.
They haven't been in a close alignment like this since the early 13th century and your next chance to see a conjunction like this – March 2080.
