Physicists used graphs to build an extremely small magnetic field detector

Often times, it’s the smallest scientific measurements that matter most, and researchers have developed a new, super-tiny device that can detect magnetic fields even when they are extremely weak. The device, a novel superconducting quantum interference device (SQUID), is only 10 nanometers high, or about a thousandth the thickness of a human hair. It consists of two layers of graphene, …

Breathtaking new images of the sun show the popcorn-like magnetic field structure of our star

Need a little more Sun in your life? German scientists have just upgraded a solar telescope called GREGOR at the Teide Observatory in the Canary Islands. The result is a spectacular new collection of images of our star. “This was a very exciting, but also extremely challenging project,” said Lucia Kleint, scientist at the Leibniz Institute for Solar Physics in …

Ravens sent Earl Thomas home on Friday after a heated argument with Chuck Clark in the field, the source says

OWINGS MILLS, Md. – Baltimore Ravens Safety Earl Thomas was sure to see Chuck Clark sent home Friday after a heated argument in the field, a source told ESPN and confirmed several reports. The incident between Thomas and Clark was triggered by a missed assignment from Thomas, a source said. Thomas and Clark yelled at each other on the sidelines …

A weak spot in the earth’s magnetic field grows and can damage satellites

Earth’s geomagnetic tank has cracked and is growing. This weak point in the magnetic field of our planet is located over the southern Atlantic between South America and southern Africa. Since 2014, the dent has grown in size and is starting to split while simultaneously weakening. For the people on the ground, this is nothing to worry about: the protective …

A solar flare is aimed at the earth’s magnetic field

On Sunday, August 16, the National Oceanic and Atmospheric Administration (NOAA) discovered a powerful solar flare Eruption from the sun’s surface. The slow motion flare created a shock wave through the atmosphere of our yellow dwarf star – and a small wave in the direction of the Earth’s magnetic field. According to predictive models made by NOAA, coronal mass ejection …
