What exactly is IceCube? How does it use the South Pole ice to see neutrinos from outer space? Image: Yuya Makino, IceCube/NSF

IceCube is a flagship experiment in neutrino and multimessenger astronomy thanks to the discovery of very high energy cosmic neutrinos and the detection of the first likely source of high-energy neutrinos, a blazar that was also observed with gamma rays and lower energy photons.

IceCube is designed to look for point sources of neutrinos in the teraelectronvolt (TeV) range to explore the highest-energy astrophysical processes. IceCube is part of a series of projects developed and supervised by the University of Wisconsin–Madison.

IceCube, the South Pole neutrino observatory, is a cubic-kilometer particle detector made of Antarctic ice and located near the Amundsen-Scott South Pole Station. It is buried beneath the surface, extending to a depth of about 2,500 meters.

2013年11月22日 · IceCube, a large-volume Cherenkov detector (1) made of 5160 photomultipliers (PMTs) at depths between 1450 and 2450 m in natural Antarctic ice (Fig. 1), has been designed to detect these neutrinos at TeV-PeV energies.

Motivated by this discovery, the IceCube collaboration examined lower-energy neutrinos detected over the previous several years, finding an excess emission at the location of the blazar. Thus, blazars are a source of astrophysical neutrinos. Science, this issue p. 147, p. eaat1378.

In 2012, IceCube detected the highest energy neutrinos ever observed at that time. During its 10 years of operation, scientific breakthroughs enabled by IceCube have been published in over 150 papers in scientific journals. In celebration of the facility’s 10th anniversary, learn more about IceCube through images.

2014年2月3日 · If a substance with fast-moving atoms (like a hand in the experiment below) meets a substance with slower atoms (the ice cube below), the energy from the fast-moving atoms wants to move into the substance with slower moving atoms. When the two substances are at the same temperature, scientists call this “thermal equilibrium.” What is Heat?

2025年2月10日 · Our easy ice cube fishing activity is perfect for at home or in the classroom. Ice Science Experiment – Let’s Go Fishing! This ice science experiment doesn’t have to be prepped beforehand (unless you do not have any ice cubes on hand). You could even make fun ice cubes with novelty ice cube trays.
