The Green Bank Telescope in West Virginia has developed a new radar system, called the Next Generation Radar (ngRADAR), which provides more detailed astronomical radar capabilities than ever before. This brand of science has been used to probe the planets and asteroids around us, measuring their speed as they whiz around the sun and imaging the details of their surface. The Green Bank Telescope has a 100-meter-diameter dish and is the largest steerable antenna on Earth, which makes it uniquely suited for detecting near-Earth asteroids (NEAs) and observing the moon. The ngRADAR system uses the Green Bank Telescope as a … Continue reading How the Green Bank Telescope’s ngRADAR System is Helping to Protect Earth from Asteroids
