See the gorgeous ringed planet Saturn and its moons

Now is a great time to see Saturn, perhaps the most beautiful planet in the night sky.

Saturn will be in opposition to the sun on Friday at 10 p.m. EDT (0200 GMT on May 23). This means that the ringed planet will be directly opposite the sun in our sky. It will rise as the sun sets in the evening, shine brightly all night long, and set as the sun rises at dawn.

If you just look at the sky on a single night, everything seems quite static. But if you watch Saturn over a period of a few weeks, for example, and note its position against the background stars, you will see that it is in constant motion.

Currently Saturn is moving with what is called “retrograde motion,” from left to right against the background stars. This is actually an optical illusion caused by the Earth’s much more rapid movement around the sun. Once the Earth is well past Saturn in early August, Saturn will appear to reverse directions and begin moving in its true direction, from right to left.
