Tracking bird migration with radar routes

Tracking Bird Migration with Radar

The same technology used to detect weather systems and airborne phenomena is a major source of ornithological information, particularly during spring and fall bird migrations. Radars (Radio Detection and Ranging) are useful in studying the flight patterns, locations and densities of migratory birds — information that is otherwise difficult to observe, since many birds migrate …

Deep inside the planet Jupiter, pressures reach millions of times those on Earth’s surface. There, the element hydrogen undergoes a radical transformation. I have read several science articles about there being metallic hydrogen at Jupiter’s core. If we could create this sort of metal here on Earth, what could it be used for? The element …
