This 3D Quantum Gas Clock Could Redefine Time

Jun Ye: “The reason we get very excited talking about clocks is not just really making time, but really about exploring the frontier problems of quantum physics. Clock, is, I feel, one part of the human endeavor. You can actually turn that into a quantum physics playground.” Inside this basement lab a team of physicists […]

How Mission Designers Invent Futuristic Spacecraft

A submarine that can dive through Titan’s methane seas. A celestial hopper that can harvest frozen nitrogen as propellant. These are the types of futuristic spacecraft that could explore distant worlds for us. But while they look straight from science fiction, there’s actually an in-house conceptual design team at NASA behind them. I’m Steve Oleson. […]

How These Self-Aware Robots Are Redefining Consciousness

I think there’s a valid concern that maybe we’re giving machines too much power. Maybe we don’t want machines to be self-aware. In my opinion, everybody should understand that this technology is around the corner. Your children, your grandchildren are going to be living in a world where there are machines  that are on par and possibly […]

An Interstellar Mission Found Something Unexpected at Our Solar System’s Edge

Every 176 years, the four planets in our outer solar system present us with a rare opportunity. They’ll align in such a unique way, that it’s possible to use their gravitational forces to slingshot from one planet to the next. A PhD student figured this out back in 1965 during his summer job at the […]

How Einstein’s Eclipse Changed the Course of Physics Forever

About every 18 months, the Moon passes directly between the Sun and the Earth for a total solar eclipse. This alignment casts a brief shadow on Earth that we can track … and its location changes each time. This year’s eclipse swept across South America, stretching over Chile and Argentina. It was visible over the […]

How Earth’s Magnetic Field Twists and Buckles During Solar Storms

Traveling at the near speed of light, energetic particles shooting out from the sun can zip through space, smack into our planet’s atmosphere, and cause incredible disruptions. And one of the biggest impacts we know of happened during the tail end of the Vietnam War. President Nixon really wanted to pull us out, but wanted to […]

Mini-Nuclear Reactors Are Coming, and They Could Reinvent the Energy Industry

Pat, we have a reactor trip on Unit 5. Containment is isolated. Demon water is isolated. CVCS is isolated. DHR is in service. And pressurizer heater trips has occurred. All safety functions are green. Understand. We’ve got a reactor trip on Unit 5 and all safety functions are green. That’s correct. Ryan, can you take […]
