A large cloud of Saharan dust moving across the Atlantic Ocean over the past week has reached the Caribbean and South America. The dust will remain over the region for the next couple of days, limiting visibility and lowering air quality. After that, it's…
New data provided by NASA's AIM (Aeronomy of Ice in the Mesosphere) satellite mission shows that the first noctilucent clouds (NLCs) of summer have been trending earlier since 2007, when the spacecraft was launched. Each year, NLCs first appear in the Arctic and…
Noctilucent clouds (NLCs) have been spotted over Poland, Czech Republic, Canada, and Scotland, among other countries, on May 25 and 26, marking an early start to the northern hemisphere's 2021 NLC season. The clouds are rapidly intensifying. In only four days…

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…
A rhythmic pattern sounding like a low-frequency musical note was detected from the magnetosphere over Lofoten, Norway, on Monday, January 18, 2021. The rare event, which is also called a pulsation continuous, is a strictly regional phenomenon, according to…
Noctilucent clouds (NLCs) have returned to the South Pole and made a very rare appearance over Argentina more than one month after the beginning of the southern hemisphere season. Gerd Baumgarten of Germany's Leibniz-Institute of Atmospheric Physics, whose…
