    CNN) -- NASA scientists revealed Friday a first-of-its-kind image from space showing reflecting sunlight from a lake on Saturn's largest moon, Titan.

    It's the first visual "smoking gun" evidence of liquid on the northern hemisphere of the moon, scientists said, and the first-ever photo from another world showing a "specular reflection" -- which is reflection of light from an extremely smooth surface and in this case, a liquid one.

    "This is the first time outside Earth we've seen specular reflection from another liquid from another body," said Ralf Jaumann, a scientist analyzing data from the Cassini unmanned space probe.

    Jaumann said he was surprised when he first saw the photos transmitting from Cassini, orbiting Saturn about a billion miles from Earth.

    "It was great because if you look at photos of planets, you mostly see nothing is happening. But in two hours we saw a glint of light getting brighter."

    Titan's similarities to Earth have attracted NASA's attention for decades. It's the only body besides our own in the solar system that is believed to have liquid on its surface. Like Earth, Titan has an atmosphere which is mostly nitrogen.

    Experts believe the presence of liquid on a planet or moon improves the chances that some kind of life could develop there.

    The question is: How did the velicoraptors get to Titan to become a "Fossil fuel" lake

    A daring proposal to try to put a "boat" down on a sea of Saturn's moon Titan is about to be submitted to Nasa.

    The scientific team behind the idea is targeting Ligeia Mare, a vast body of liquid methane sited in the high north of Saturn's largest moon.

    The concept will be suggested to the US space agency for one of its future mission opportunities that will test a novel power system.

    It would be the first exploration of a planetary sea beyond Earth.
