The green polar lights threw light across the ice. They are caused by disturbances in the magnetosphere by solar wind, causing particles to move into the upper atmosphere and emit light.

The aurora is a natural light predominantly seen in the high-latitude regions around the Arctic and Antarctic. It is caused by disturbances in the magnetosphere by the solar wind, which is a stream of charged particles escaping the Sun.

Until 2014, Antarctic sea ice levels were actually increasing- but since then according to satellite data, there's been a 'precipitous' nosedive in ice levels. Scientists are now trying to find out why, and what it might mean.
