ARLA/CLUSTER: Nuvens " Electric-blue " aparecem sobre a Antártida

[João Costa > CT1FBF]

Electric-blue clouds appear over Antarctica

This just in from NASA's AIM spacecraft: The sky above Antarctica is
glowing electric blue.

A ring of bright noctilucent clouds has formed around the South Pole.
The annual apparition of these clouds is one of the earliest on
record, and may hint at the workings of climate change.
