Astronomers Search for the Sun’s Long-Lost Solar Siblings
While a family reunion is highly unlikely, Australian and European astronomers are still trying to find our Sun’s long-lost solar siblings which are now scattered throughout the sky. To do so, the scientists examined the of some 350,000 stars in the Milky Way – as though they were mapping each star’s DNA. The sun was […]
SWARM Tracks the Ocean’s Magnetic Field
Earth’s magnetic fields protect us from deadly radiation from high-energy solar particles and cosmic rays. Most of this protective shield is produced by a vast amount of hot molten iron swirling around in our planet’s outer core. But there’s another little-known contributor to our geomagnetic field. It’s the salty and electrically conductive ocean. When salty ocean […]
Scientists Discover How Marine Mammals Hold Their Breath for Long Periods
Special properties of an oxygen-binding protein in the muscles of marine mammals, such as seals, whales and dolphins, are the reason these animals can hold their breath underwater for long periods of time, according to a new study. Many of these mammalian divers can hold their breath underwater for over an hour, while land-based mammals, […]
