Large meteoritic event over Antarctica 430 000 years ago

An international team of scientists has found new evidence that a low-altitude meteoritic event occurred over Antarctica 430 000 years ago. Cosmic particles recovered on the summit of Walnumfjellet indicate that an unusual touchdown event reached the continent's...

New model replaces dark energy theory with magnetic forces

It has been long believed that 70 percent of the universe is composed of dark energy, which makes it expand at an ever-increasing rate. However, a new model by researchers from the University of Copenhagen (UCPH) suggests that the expansion is due to a dark...

Research reveals unknown mechanisms that generate auroras

New research has revealed an unknown mechanism of the magnetosphere-- electrons from the Sun are propelled by electrical energy higher than previously thought, ultimately creating displays of northern and southern lights or auroras. The formation of auroras starts...
