 Context examples 

This is farther than any other neutrino whose origin scientists can identify.

(NASA’s Fermi Traces Source of Cosmic Neutrino to Monster Black Hole, NASA)

At this energy, the Earth's absorption of neutrinos is relatively small; the lowest-energy neutrinos in the study largely served as a baseline measurement for neutrinos that the Earth did not absorb.

Unlike a normal neutrino, which interacts by a subatomic force, this possible new particle would be affected only by gravity and is dubbed a “sterile neutrino.”

(Measuring Growth of Universe Reveals a Mystery, The Titi Tudorancea Bulletin)

This neutrino traveled 3.7 billion years at almost the speed of light before being detected on Earth.

(NASA’s Fermi Traces Source of Cosmic Neutrino to Monster Black Hole, NASA)

Neutrinos are subatomic particles, most of which pass through anything and everything, only very rarely interacting with matter.

Such speedy particles are collectively called “dark radiation” and include previously known particles like neutrinos, which are created in nuclear reactions and radioactive decays.

(Measuring Growth of Universe Reveals a Mystery, The Titi Tudorancea Bulletin)

This high energy strongly suggested that the neutrino had to be from beyond our solar system.

(NASA’s Fermi Traces Source of Cosmic Neutrino to Monster Black Hole, NASA)

IceCube's sensors do not directly observe neutrinos.

(Antarctic detector offers first look at how Earth stops high-energy neutrinos in their tracks, National Science Foundation)

Neutrinos show the complex processes that occur inside the environment, and cosmic rays show the force and speed of violent activity.

(NASA’s Fermi Traces Source of Cosmic Neutrino to Monster Black Hole, NASA)

An interdisciplinary team of researchers using the IceCube Neutrino Observatory in Antarctica has measured how certain high-energy neutrinos are absorbed by the Earth, as opposed to passing through matter as most neutrinos do.
