Two NASA aurora research rockets launched from Poker Flat Research Range earlier this month provided good data for learning more about the fastest observable variations of the solar wind-driven light displays. One rocket gathered information about flickering aurora, and the other gathered data about fast-pulsating aurora. Flickering auroras are fast, localized and associated with higher-frequency […]
Most electrons that create the aurora have a moderate amount of energy, but scientists want to know more about how electrons on either side on that scale — more and less energy — affect the electrical properties of the ionosphere, the part of Earth’s upper atmosphere that is ionized by the sun. These properties define […]
“In our lifetimes, there has never been a president as willing as Trump is to foment hate and violence among his supporters,” said one local advocacy group. Warnings that Republican nominee Donald Trump poses a fascist threat to U.S. society as a whole—and to the nation’s immigrants in particular—grew Friday following his visit to Aurora, Colorado, where […]
