NASA's Perseverance rover recently had a front-row seat to a rare case of Martian cannibalism: It filmed a massive, swirling "dust devil" engulfing a smaller twister on the Red Planet.
The roaming robot captured the epic encounter on Jan. 25, on the 1,399th sol (Martian day) of its mission. In the video, a smaller devil, which is barely visible in the images, follows in the wake of a larger twister (moving from left to right), before getting too close and being sucked into the larger vortex. The rover was around 0.6 mile (1 kilometer) from the pair when this happened.
