Stefan Westerhoff, a professor in the physics department at the University of Wisconsin–Madison, passed away on Sunday, August 5, 2018, after a long illness. He was 50.
Last week the weather was a bit mixed, and the winterovers had their lunar eclipse viewing marred by blowing snow. Regardless, they still got together outdoors for a group photo.
So much ice, yet it’s no mean feat to keep a stable water supply for the folks at the South Pole. Housed in the shack shown in this image is a rodwell, which is how they get their water. Hot water is sent down a hole to a cavity deep in the ice, and a continuous flow of water is maintained to prevent the rodwell from freezing.
There were two bingos last week at the Pole: (1) the game, where some improvising was required for the tiles, and (2) the exclamation, which was well warranted for IceCube’s recent multimessenger results.
Last week at the Pole, the weather was perfect for starting out the second half of winter—cold but calm conditions, with some of the prettiest auroras.
Since cosmic rays were discovered in 1912, scientists have sought the origins of these mysterious particles. In September 2017, a flash of blue light in the ice deep beneath the South Pole set researchers on a path to resolving this century-old riddle.
The 4th of July is now behind us, but this view of the South Pole station continues with the red, white, and blue theme, while the other side of the station just shows the blue sky and the white snow. These image were only possible due to a bright moon, bright enough to illuminate the tracks in the snow surface.
The recent stretch of bad weather finally broke, showing off some nice auroras. Here, you can make out a bright spot in the sky, which is Mars, soon to reach its closest approach to Earth in many years.
Midwinter is approaching, so the winterovers got together for a group photo that they’ll use to send out traditional greetings to other stations. Looks like a bunch of happy campers.
Nice snow drift! Or sastruga, as one might say at the Pole. This enormous snow structure appeared inside the logistics arch, which is a large unheated storage facility, pushed through to the inside through closed doors. That is one strong wind (or one leaky door).
