Saturn: still uncrowded

Scientists have discovered waves in Saturn, the second largest planet in the Solar System.

Using NASA's Cassini spacecraft, scientists found the first ever waves outside of Earth, on Titan, Saturn's largest moon.

But if you're already preparing your surfboard for an outer space surfing experience, know that the local seas and lakes are filled with liquid methane and ethane. It won't be easy.

Astronomers had to wait for the spring winds to come around for Saturn, in order to confirm the existence of waves in the planet.

"If correct, this discovery represents the first sea-surface waves known outside of Earth. Oceanography is no longer just an Earth science," scientists tell.

Longboards won't be enough to ride Saturn's largest swells. The local waves are no more than two centimeters high, although extremely glassy.

However, don't lose hope. Winds are anticipated to pick up as Titan's northern hemisphere and more wave spots may be spotted and identified in the next years.

Launched in 1997, Cassini has explored the Saturn system for more than nine years. NASA plans to continue the mission through 2017.
