Video: Test Rig Shows What Happens when Drone Hits Flesh at 33mph

How much damage can a tiny drone propeller really do when it comes up agains something as solid as a person? That's the question Aalborg University in Denmark is answering with a rig that can ram a spinning drone propeller into a piece of flesh at 33mph... and record the results in slow motion.

NYPD Helicopter Narrowly Avoids Crashing Into Two Camera Drones

Update: Initial reports that the 'drones' flew at the helicopter may not be entirely accurate. Click here to read our followup coverage.

Earlier this week, two drones narrowly avoided a collision with a New York Police Department’s helicopter just over the George Washington Bridge. It took aversion maneuvers by the quick-thinking helicopter pilot to ensure no collision took place. But just because there wasn’t any critical harm done doesn’t mean the individuals behind the reckless drones are getting off free.

Animation Shows How the Galaxy Shapes in Space Photos Come About

Space collisions are massive, unbelievably powerful events. When two galaxies collide -- that is, when their gravitational fields start interacting with one another -- the resulting billion-year-long process contorts and twists the galaxies into the fascinating shapes we've seen in photographs taken by powerful space telescopes.

The above video is a supercomputer simulation of two galaxies going through a many-hundred-million-year-long collision. As the galaxies merge into the known stages of collision that have been photographed by Hubble, the video is paused and replaced with a photograph of that stage taken IRL.
