## IceCube Neutrino Observatory
The IceCube Neutrino Observatory sits on tons of clear ice at the South Pole, allowing scientists to detect neutrino interactions.
## Neutrinos: Ghost Particles
All visible matter in the universe, stars, planets, you, me, is made up of some combination of 12 fundamental particles. The lightest and most abundant are neutrinos.
## Neutrinos Penetrate Everything
Neutrinos have uniquely small masses and the ability to penetrate just about anything, making them a razor-sharp tool for physicists to study particle interactions.
## Why Neutrinos Matter
Neutrinos may help researchers understand why the universe is predominantly made of matter rather than equal parts matter and antimatter.
## Neutrino Detection Challenge
Physicists have risen to meet this challenge by employing specialized materials at industrial scales to detect these elusive particles.
## 2026 Nobel Prize in Physics
Belgian physicist Francis Halzen received the 2026 Nobel Prize in physics from the Royal Swedish Academy of Sciences in Stockholm on Oct. 6, 2.026.
## Neutrino Oscillations
Neutrinos come in three types: electron neutrino, muon neutrino, and tau neutrino, which can change types through a process called oscillation.
## Super-Kamiokande Experiment
The Super-Kamiokande experiment discovered in 1998 that neutrinos produced in the atmosphere were oscillating as they traveled through the Earth.
## Sudbury Neutrino Observatory
The Sudbury Neutrino Observatory discovered in 2002 that neutrinos produced in the Sun were also changing their type as they traveled from the solar core to Earth.
## IceCube Construction
IceCube’s digital sensors wait to be deployed into the Antarctic ice, with 5,000 optical sensors sunk more than 1 mile under the surface.
## First Deep Space Neutrinos
IceCube discovered neutrinos of such high energy that they had to be astrophysical in origin, marking the first detection of deep space neutrinos.
## Neutrino Origin Confirmed
A few years later, IceCube saw an energetic neutrino at the same time as a NASA space telescope spotted an energetic gamma ray from the same location, confirming the origin of astrophysical neutrinos.
## Key takeaway

IceCube Neutrino Observatory discovered neutrinos from deep space, marking the first detection of astrophysical neutrinos.
