Saturn, the 6th planet of our solar system, will be at its brightest tonight as it rises while the sun sets. It will be visible without the help of optical aids, but you’ll need a telescope to see its rings. Telescope viewers may also catch some of Saturn’s 83 orbiting moons.

Tonight, check out Saturn in the evening sky. The Moon passes north of the ringed planet around 10pm. In addition, this pairing will be located within Aquarius. You may need to use binoculars or telescope, as Saturn's light may be washed out by the Moon! #wherethestarshangout

Don't forget! Look at the early morning sky to see Mars & Jupiter. Two planets together, look toward the east. Mars & Jupiter will rise around the same time in the middle of the night, & climb slowly into the sky before fading from view as dawn breaks. adlerplanetarium.org

It's that time of the summer to keep your eyes on the skies for the Perseids! You could observe up to 60 meteors per hour. No need for a telescope tonight, even in a light polluted area, as you could still see up to 10-30 meteors per hour! Happy viewing! #wherethestarshangout
