Earth-like Moon

NASA's Juno mission made its 39th close flyby of Jupiter recently and captured an incredible image of the planet's southern hemisphere. However, a closer look at the image also revealed two more heavenly bodies nearby — Jupiter's moons Io and Europa.

Titan, Saturn's aptly named largest moon, is exactly the kind of place we want to visit: NASA describes it as "one of the most Earth-like worlds we have found to date." It has a dense atmosphere and stable lakes and rivers.

The ocean on Jupiter's icy moon Europa may have the Earth-like balance of chemical energy necessary for life, even if the moon lacks volcanic hydrothermal activity, a new NASA study suggests.

Saturn's moon Titan puts on quite a show in the latest composite image from NASA. Taken with the Cassini spacecraft, the new image uses near-infrared wavelengths to cut through Titan's thick layers of haze. Beneath, you'll notice, is a shockingly Earth-like moon.

Unlike the Earth, Titan has no magnetic field of its own, but is surrounded by Saturn's rapidly rotating magnetic field, which drapes forming a comet-like tail around the moon.
