IceCube, the Antarctic neutrino detector that in July of 2018 helped unravel one of the oldest riddles in physics and astronomy — the origin of high-energy neutrinos and cosmic rays — is getting an upgrade.
The sky is beginning to take on different colors at the Pole, depending on which direction you’re looking. There’s a hazy band of orange along the horizon, but facing away toward the station the sky appears blue.
It was a quiet week at the Pole. And with some bad weather, it was a good time to roam around and take some indoor photos.
It’s a slow sunrise at the South Pole, with light creeping up from the horizon little by little each day. But even as the twilight approaches and the sky brightens, it’s still dark enough to discern some auroras here and there.
