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 IceCube Lab has accumulated quite a bit of snow over the winter. And that snow, there and elsewhere, must be cleared away before planes bringing fresh crew arrive—plenty to do.
Now that the sun is up 24/7 at the South Pole, it’s hard for the winterovers to even imagine the auroras they were enjoying in the dark sky just a month or so ago. Everything is now visible.
