Faster-than-light travel is impossible according to our current understanding of physics. Wormholes are theoretically possible but require unstable, exotic matter to stabilize. Generation ships are a ...

My telescope, set up for astrophotography in my light-polluted San Diego backyard, was pointed at a galaxy unfathomably far from Earth. My wife, Cristina, walked up just as the first space photo ...

For the first time, physicists have simulated what objects moving near the speed of light would look like — an optical ...

About 60 years ago, the original Star Trek series featured a technology called a “warp drive,” which allowed space travel at speeds much faster than light. Theoretical physicist and philosopher Albert ...

Some things we see in space appear to outpace light. Now we are learning to harness these bizarre optical illusions to ...
