NASA has detected a strange orbital movement of two Neptune moons

Life is not always easy for astrophysicists: just when they've discovered another aspect of the movement patterns in our solar system, two of the moons of Neptune come to mess things up. The two eligible moons are Naiad and Thalassa, both about 100 kilometers or 62 miles wide, and running around their planet in a race called "Dance of Avoidance" …

Generation of extreme ultraviolet rays with time-varying orbital angular momentum

Pulses with Twist and Torque Structured light rays can serve as eddy beams with optical angular momentum and have been used to improve optical communication and imaging. Rego et al. generated dynamic vortex pulses through the interference of two time-delayed vortex beams with different orbital angular momentum through the process of generating high harmonics. A controlled time delay between pulses …

Shutdown allows orbital space sculptures orbiting

The closure of the government has closed museums in Washington and endangered exhibitions such as the National Gallery of Art's Tintoretto show, which was originally scheduled to open on March 10. It has also endangered an artist project near the Beltway: "Orbital Reflector," a sculpture by Trevor Paglen that was recently put into orbit. The sculpture is not lost as …
