Like something out of the glowing alien world of James Cameron's "Avatar," researchers surveying waters around the famed Mariana Trench have discovered a new species of jellyfish that looks out-of-this-world.

The stunningly beautiful creature was discovered at a depth of 2.3 miles using the National Oceanic and Atmospheric Administration's (NOAA) underwater remote-operated vehicle, Deep Discoverer. Marine biologists believe the "UFO Jelly" is a type of "hydromedusa" of the genus Crossota, a kind of ambush-predator that lies in wait for something to unwittingly drift by its many out-stretched tentacles. The glowing yellow and red areas inside its bell are likely the animal's gonads and digestive system.

The UFO Jelly, as it has been dubbed, is just one of many new species the Deep Discoverer has brought to light recently, including the reveal of a "ghost octopus" found in March at a depth of 14,000 feet.

For those interested in following the research team as they make more discoveries, the three-cruise expedition from April 20 to July 10 is being live-streamed in glorious 720p. Cameras will run from 4:30 p.m. EST to 12:30 a.m., so grab some popcorn and prepare to have you mind blown by whatever else is hiding down there.

The video below will give you a sense of what you might see:
