The area of space controlled by Earth’s magnetic field is called the magnetosphere. Within this vast magnetic bubble, scientists have observed an electric field that stretches from the morning side of Earth to the evening side. This large-scale electric force is a major influence on geomagnetic disturbances, including the storms that can disrupt satellites and…

When electricity moves through wires, some of its energy is lost along the way. That loss, however, might not be inevitable. Researchers at Penn State have developed a new way to identify materials known as superconductors — substances that can carry electric current with zero resistance, meaning no energy is wasted during transmission. The Challenge…

Each fall, the Taurid meteor shower brightens the night sky from late October through early November. Known as the “Halloween fireballs,” the meteors are named for the constellation Taurus (the bull), where they appear to originate. The best views come from dark-sky areas far from city lights. In New Mexico, where wide open landscapes and…
