Project Helianthus—a solar-sail-driven geomagnetic storm tracker

Solar storms captured the imagination of much of the American public earlier this year when auroras were visible well south of their typical northern areas. As the sun ramps into another solar cycle, those storms will become ...

A tower on the moon could provide astronauts with light, power and guidance

Technologies for enabling NASA's Artemis mission are coming thick and fast, as plenty of problems must be solved before a permanent human presence on the moon can be established. A novel idea from Honeybee Robotics, one of ...

The Hubble telescope has shifted into one-gyro mode after months of technical issues

Imagine keeping a laser beam trained on a dime that's 200 miles away. Now imagine doing that continuously for 24 hours, while riding a merry-go-round. Does it seem difficult? Well, that's basically what the Hubble Space Telescope ...

Research team proposes a novel type of acoustic crystal with smooth, continuous changes in elastic properties

In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye ...
