Back in 2013, the IceCube Neutrino Observatory—a cubic-kilometer neutrino detector embedded in Antarctic ice—announced the first observation of high-energy (above 100 TeV) neutrinos originating from outside our solar system, spawning a new age in astronomy. Four years later, on September 22, 2017, a high-energy neutrino event was detected coincident with a gamma-ray flare from a […]

Neutrinos are ghostly, nearly massless particles that can travel extraordinarily large distances unimpeded. Because of this, neutrinos act as “messengers,” harboring information about their sources. Although most detected neutrinos originate from the sun or Earth’s atmosphere, there exist highly energetic astrophysical neutrinos that originate from the farthest reaches of outer space. In 2013, the first […]
Every second, 100 trillion neutrinos pass through the human body. These tiny, almost massless particles travel tremendous distances through space while carrying information about their sources and are created by some of the most energetic phenomena in the universe. But neutrinos are incredibly difficult to detect, requiring a one-of-a-kind detector that can “see” these nearly […]
So, you’ve arrived at the Geographic South Pole—or have you? The sign might not help much on its own, but now that the sun is out we can see where we are from the surroundings (yes, it’s the geographic South Pole). Below is a close-up view of the current 2022 South Pole marker, which was […]
Now there’s a bright sun! And it looks like it’s shining over a body of water with choppy waves. But that’s just an illusion, stemming from the shadows cast by a low sun over the rough icy surface at the South Pole. There’s another apparition above, where something appears to be stretching across the entire […]
The IceCube Neutrino Observatory is one of a growing number of science initiatives to use scalable cloud infrastructure to process massive datasets. […]
Last week was another quiet week at the Pole. And it was cloudy and windy again, with the slowly rising sun mostly obscured in the sky. IceCube’s winterovers were paged a few times to go out to the IceCube Lab, so they were out and about in the cloudy, windy landscape. Above we see the […]
There’s nothing wrong with “quiet,” especially where detector operations are concerned. That’s a good thing. And last week was relatively quiet at the Pole. IceCube’s winterovers did have to trek out to the IceCube Lab anyway, though, for some hands-on work for a routine operation. On their walk, Moreno captured some nice photos of the […]
IceCube collaborator and Harvard physics professor Carlos A. Argüelles-Delgado was chosen as one of Science News’ 2022 SN 10: Scientists to Watch. For the seventh year, Science News SN 10: Scientists to Watch list features 10 early- and mid-career scientists driven by their curiosity and sense of wonder and moved to solve some of the world’s biggest problems. Every year, Science […]
