Low-energy solar particles from beyond Earth found near the Sun

Posted by in categories: particle physics, space

Using data from NASA’s Parker Solar Probe (PSP), a team led by Southwest Research Institute identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. PSP is venturing closer to the Sun than any previous probe, carrying hardware SwRI helped develop. Scientists are probing the enigmatic features of the Sun to answer many questions, including how to protect space travelers and technology from the radiation associated with solar events.

“Our main goal is to determine the acceleration mechanisms that create and transport dangerous high-energy particles from the solar atmosphere into the solar system, including the near-Earth environment,” said Dr. Mihir Desai, a mission co-investigator on the Integrated Science Investigation of the Sun (IS?IS) instrument suite, a multi-institutional project led by Principal Investigator Prof. Dave McComas of Princeton University… IS?IS consists of two instruments, Energetic Particle Instrument-High (EPI-Hi) and Energetic Particle Instrument-Low (EPI-Lo). “With EPI-Lo, we were able to measure extremely low-energy particles unexpectedly close to the solar environment. We considered many explanations for their presence, but ultimately determined they are the smoking gun pointing to interactions between slow- and fast-moving regions of the solar wind that accelerate high-energy particles from beyond the orbit of Earth.

Researchers demonstrate optical backflow of light

Posted by in categories: particle physics, quantum physics

Researchers at Tel Aviv University have for the first time demonstrated the backflow of optical light propagating forward. The phenomenon, theorized more than 50 years ago by quantum physicists, has never before been demonstrated successfully in any experiment—until now.

“This ‘backflow’ phenomenon is quite delicate and requires exquisite control over the state of a particle, so its demonstration was hindered for half a century,” explains Dr. Alon Bahabad of the Department of Physical Electronics at TAU’s School of Electrical Engineering, who led the research for the study.

“This phenomenon reveals an unintuitive behavior of a system comprised of , whether it’s a particle in quantum mechanics or a . Our demonstration could help scientists probe the atmosphere by emitting a laser and inducing a signal propagating backward toward the laser source from a given point in front of the laser source. It’s also relevant for cases in which fine control of light fields is required in small volumes, such as optical microscopy, sensing and optical tweezers for moving ,” Dr. Bahabad says.

Excalibur S GPS/laser-guided artillery shell homes in on moving target

Raytheon and the US Navy have successfully fired a precision-guided munition that can be fired from a howitzer and zero in on a moving object. The recent test of the Excalibur S round not only demonstrated its ability to switch from GPS to laser guidance to find its target, but also that its electronics and sensors can withstand the shock of being fired out of a gun.

The Excalibur S is the latest variant of Raytheon’s Excalibur line of smart projectiles. Developed by Raytheon and BAE Systems Bofors, it uses the GPS technology from the Excalibur Ib, and combines it with a semi-active laser seeker that allows it to home in on moving land and maritime targets with a miss radius of under two meters (6.5 ft).
