Researchers have recreated the bizarre spider-like features seen on the surface of Mars for the first time ever. The breakthrough could help unravel further mysteries surrounding the static Martian arachnids.

Dubbed "araneiform terrain," the Mars surface formations span over a half-mile long and have hundreds of branches that resemble spider legs, according to NASA.

Scientists at NASA's Jet Propulsion Laboratory have recreated spider-like araneiform terrain, a geologic formation found on Mars, in a lab on Earth.
