A few months after the donut-shaped Mars rock made its mysterious appearance (which we now know was thanks to being moved around by Opportunity Rover), scientists are pondering another great, and bigger, cosmic mystery — an object described as a “magic island” that suddenly appeared and then disappeared from one of Titan’s lakes.
NASA’s Cassini probe has been hanging out around Saturn’s largest moon for a while now, capturing image after remarkable image. Scientists examining those images found one that revealed a big object in the middle of one of Titan’s biggest bodies of water, Ligeia Mare, which is nearly 500 feet deep. Cassini snapped images of the sea in 2007, 2009, and 2013, and an image from July 10, 2013 shows a mysterious white blob, which scientists are calling the “magic island” until they know more. The island is approximately six miles wide and 12 miles long, and it doesn’t appear in images captured just two weeks later.
