A potentially new species of deep-sea jellyfish tripped the light fantastic for researchers during their recent MAR-ECO expedition to the Mid-Atlantic Ridge.
"This is a special kind [of trachymedusa jellyfish] which, instead of floating around in the middle of the ocean"—as most jellyfish do—"floats just centimeters above the bottom, with its tentacles touching the seafloor," team member Monty Priede said. "This is a very unusual thing."

The eclipsed sun seems to hover over the horizon on Sunday, barely lighting the high, snowy plains of Patagonia in southern Argentina.

According to Telus World of Science's Dyer, the moments before and after totality can be just as thrilling as the solar eclipse itself.

"The twilight horizon colors, weird sharp shadows, and other fleeting phenomena [surrounding the eclipse] are so immersive and overwhelming," Dyer told National Geographic News last week.
