Discovery comes from reanalysis of two-decade-old videoCredit: Riley Troyer, University of Iowa For millennia, humans in the high latitudes have been enthralled by auroras--the northern and southern lights. Yet even after all that…

A recent study analyses data collect4d at 44 of the darkest places in the world, including the Canary Island Observatories, to develop the first complete reference method to measure the natural brightness of the night sky using low-cost…
