NASA's Voyager 1 Explores Final Frontier of Our 'Solar Bubble'

Data from Voyager 1, now more than 11 billion miles from the sun, suggest the spacecraft is closer to becoming the first human-made object to reach interstellar space.

Bell Labs improves lensless camera with additional pixel on sensor

(Phys.org) —A research team from Bell Labs that developed a lensless camera has now improved upon the design by adding a second pixel to the sensor used to read data coming through an aperture array. In their paper uploaded to the preprint server arXiv, the team describes how they added a second pixel to the sensor that reads incoming light from the aperture array. Doing so required additional programming of code on an associated computer to take advantage of the additional data provided by a slightly different view of the object being captured.

Quantum engines must break down

Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and need to be modified, according to new research. The work establishes new laws in the rapidly emerging field of quantum thermodynamics. The findings have wide applications in small systems, from nanoscale engines and quantum technologies, to biological motors and systems found in the body.

On the hunt for neutrinos: Physicist seeks new ways to detect and measure the elusive particles

Every second, trillions of particles called neutrinos pass through your body. These particles have a mass so tiny it has never been measured, and they interact so weakly with other matter that it is nearly impossible to detect them, making it very difficult to study their behavior.

Satellites Launch to Bring Rural Areas Online

What did we do before Internet? Ask one of the 5 billion people on the planet today who still aren't connected to the World Wide Web. One company is trying to change that by launching a series of satellites that would provide fast, cheap Internet and phone service to remote areas in 180 countries.

The satellites belong to a telecom company called O3b Networks, whose name represents the "other 3 billion" people they hope to bring online by the end of the year. The quartet of satellites lau

Innovative Partnerships Expand NASA's Summer Education Reach
