Cosmic Ray & Neutrino

The Cosmic Ray & Neutrino SIG will serve as a focal point and forum for the cosmic ray community to support current and future cosmic ray science. CRN SIG is open to the scientific community.

About CRN SIG

Assessing Current and Future Needs for Cosmic Ray Science in Space

The Cosmic Ray and Neutrino Science Interest Group (CRN SIG) will provide quantitative metrics and assessments to NASA with regard to current and future needs of the cosmic-ray astrophysics community.

The Cosmic Ray and Neutrino SIG will study major open science questions. CRN SIG will also survey current and planned (US and International) space-based and ground-based projects, investigate state-of-the-art capabilities, determine next generation technology needs, and evaluate potential science returns from new technologies and capabilities to develop a vision for the future of cosmic ray science in space.

More About Fermi Gamma Ray Discoveries about Assessing Current and Future Needs for Cosmic Ray Science in Space
NASA’s Fermi Closes on Source of Cosmic Rays. New images from NASA’s Fermi Gamma-ray Space Telescope show where supernova remnants emit radiation a billion times more energetic than visible light. The images bring astronomers a step closer to understanding the source of some of the universe’s most energetic particles — cosmic rays. Fermi mapped GeV-gamma-ray emission regions (magenta) in the W44 supernova remnant. The features clearly align with filaments detectable in other wavelengths. This composite merges X-rays (blue) from the Germany-led ROSAT mission, infrared (red) from NASA’s Spitzer Space Telescope, and radio (orange) from the Very Large Array near Socorro, N.M.
