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 […]
Radioactive Material Found in Fracking Waste; Searching Space for H20
Radioactive Isotopes Found in Fracking Waste US oil and natural gas production, has been boosted in recent years by a drilling process known as hydraulic fracturing, commonly called “fracking.” But this practice has also been criticized for its possible impact on the environment because of the wastewater this method generates. A new study published in […]
Study Confirms Earth’s Magnetic Field is Weakening
Earth’s magnetic field is weakening, according to measurements taken over the past six months by the European Space Agency’s (ESA) Swarm satellite constellation. The measurements–taken between January and June 2014–come from the first high-resolution results made by Swarm, and also indicate that the magnetic field has declined most dramatically in the Western Hemisphere while increasing […]
