Looks like time travel is possible… for particles of light.

Using a photon, physicists have managed to simulate quantum particles traveling through time. Studying the photon's behavior could help scientists understand some inexplicable aspects of modern physics.

"The question of time travel features at the interface between two of our most successful yet incompatible physical theories — Einstein's general relativity and quantum mechanics," University of Queensland's Martin Ringbauer says in a news release. "Einstein's theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules."

The James Webb Space Telescope, NASA's next flagship space observatory, has passed a major milestone on its road to its planned 2018 launch: the delivery of the last three mirrors that will make up its complicated infrared-seeking innards.

Several key conditions came together to create this award-winning shot. These included a dark night, few clouds, an epic auroral display, and a body of water that was both calm enough and unfrozen enough to show reflected stars. The featured skyscape of activity and serenity appeared over Iceland's Vatnajökull Glacier a year ago January, with the Jökulsárlón Iceberg Lagoon captured in the foreground. Aurora filled skies continue to be common near Earth's poles as our Sun, near Solar Maximum, continues to expel energetic clouds of plasma into the Solar System.
