Saturn will shine bright near the nearly full moon on Tuesday (May 13), just days after the ringed planet reached opposition, its best show of 2014. Here's how to see Saturn near the moon.

Photographs taken by NASA's Cassini probe in April 2013 show a bright arc about 750 miles long and 6 miles wide at the edge of Saturn's outermost ring. This arc was probably created by the gravity of a small, icy object nearby — possibly a newborn moon.

Enceladus' ocean is about 6 miles deep and lies beneath a shell of ice 19 to 25 miles thick. Further, it's in direct contact with a rocky seafloor, theoretically making possible all kinds of complex chemical reactions.
03 April 2014, 02:00 PM ET
