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.
A few aircraft stopped at the South Pole last week for refueling. The plane here is a Basler BT-67, flying for the Australian Antarctic Program.https://en.wikipedia.org/wiki/Basler_BT-67
Since the sun will soon be gone for quite a long stretch, you might as well try to get as much of it while you can. Last week, IceCube winterover Yuya did just that with his camera, capturing a nice time-lapse of the sun around midnight that made a little “smile” in the sky.
The last of IceCube’s summer crew have departed from the South Pole, leaving IceCube winterovers John and Yuya on their own. They are well trained and ready for their adventure.
There are theories that say neutrinos—shy, lightweight fundamental particles—may provide the key to understanding dark matter. So a group of researchers—including some from the Wisconsin IceCube Particle Astrophysics Center (WIPAC), a research center of the University of Wisconsin–Madison—compiled and contextualized two decades of neutrino data looking for a connection to dark matter. They present a comprehensive set of limits on dark matter annihilation to neutrino pairs in a paper available on the preprint server arXiv.
