Physicists Have Developed a Ridiculously Accurate Atomic Clock

Physicists have developed an atomic clock so accurate that it would be off by less than a single second in 14 billion years. That kind of accuracy and precision makes it more than just a timepiece. It’s a powerful scientific instrument that could measure gravitational waves, take the measure of the Earth’s gravitational shape, and maybe even detect dark matter.How did they do it?

Why the 2018 Discoveries on Mars Give Us the Best Hope of Life Yet

NASA’s First Asteroid-Sampling Spacecraft Is About to Reach Its Destination. Here’s What’s Next

A NASA spacecraft is on a rendezvous with history. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) spacecraft is on final approach to asteroid Bennu for a December 3 arrival, when it will enter the asteroid’s orbit. Next comes an incredible 18 months of preparations for the spacecraft to make its date with history: landing on the rock itself in order to pick up a sample to send back to Earth. Here’s why that’s exciting.
