Neutrinos' telescopes look deeply in the Earth and deep into space

The generation of IceCube 2 is a project for building a neutrino telescope at the southern pole of ten cubic kilometers. One cubic kilometer called IceCube was completed in 2010. Neutrino telescopes are another type of telescope that comes with telescopes for visible light, X-ray, infrared, ultraviolet, microwave, radio, gamma, and gravitational waves.

They can go deeper into space for cosmic ray sources and study supernovae, and they can detect the structure within the Earth.

There are many underwater detectors of neutrinos, underground and underground detectors.

Underwater neutrino telescopes:

Baikal Deep Underwater Neutral Telescope (1993)
ANTARES (2006)
KM3NeT (future telescope, built from 2013)
Project NESTOR (developed since 1998)

Underwater neutrino telescopes:

AMANDA (1996-2009, replaced by IceCube)
IceCube (since 2004)
DeepCore and PINGU, the existing expansion and the proposed expansion of IceCube

Underground neutrino observatories:

National Gran Sasso Laboratories (LNGS), Italy, Borexino, CUORE and other experiments.
Sudan Mine, Soudana 2, MINOS and CDMS
Kamioka Observatory, Japan
Neutrino Underground Observatory, Mont Blanc, France / Italy

The next generation of the KM3NeT deep-water neutron telescope will have total cumulative numbers of about cubic kilometers, and the IceCube Gen2 detector is ten cubic kilometers. These two methods will bring much more sensitivity to detecting neutrinos. They will be three to ten times more capable than the best existing detectors. The KM3NeT detector will be built in three installation locations in the Mediterranean. The implementation of the first phase of the telescope began in 2013.

Several detectors are needed to triangulate neutrino sources in space and to analyze deep interior space of the earth.

Neutrino Tomography of the Earth

Neutrino detectors have made accurate measurements of the mass and density of the Earth. Earth interacts with neutrinos. Differences in the distribution of neutrinos passing through the Earth can be used to analyze the density and create a 3D model of the inner core and mantle. Neutrino detectors with improved sensitivity and long-term data collection will greatly improve the simulation.
