Australia’s most powerful icebreaker Aurora Australis remains aground in Antarctica near Mawson station after the ship broke free from its moorings during a blizzard on Wednesday. 

All 68 expeditioners and crew remain on board and are safe and well, an update from Australia’s Antarctic Division said. The expeditioners are expected to be transferred to Mawson research station once conditions allow. 

Blizzard conditions continued on Thursday but are forecast to ease overnight, the Antarctic Division said.

In the far north, just a few degrees from the North Pole, you might be lucky enough to see an oval shaped band of light stream across the sky. These lights are known as ’Aurora Borealis’ in the north and ’Aurora Australis’ at the South Pole.

It is well known that aurorae are accompanied by infrasound (frequencies well below the threshold of hearing ability of the human ear), but their audible sounds are still a mystery. In the 1960s, the infrasound were measured and accepted as the only sound from the aurora. Yet, there are hundreds of accounts by people claiming to have heard sounds accompanying the Northern Lights.

In All Depends on the Sun, Nicolas Perret and Silivia Ploner travel to Finland to immerse in a sonic investigation of the acoustic events related to aurora borealis.
