The Earth’s upper atmosphere has had a record breaking collapse, one that has scientists both puzzled and worried, NASA announced Thursday.
The collapse occurred during a period of low solar activity known as a “solar minimum.” During a solar minimum, sunspots and solar flare activity heavily diminish. Since the date range of a solar minimum expands over a 12-month period, it can take up to 6 months to identify one.
