NASA’s Fermi Links Ghost Particle to Galaxy

Roopesh Ojha, an astronomer at the Goddard Space Flight Center, discusses his work in neutrino astronomy using the Fermi Gamma Ray Space Telescope. The telescope identified a blazar as a potential source of a neutrino detected by the IceCube Neutrino Observatory. Neutrinos are nearly massless particles that travel through the universe, carrying unique information. The discovery links blazars to neutrino origins, although many questions about blazars remain unanswered. This research could enhance understanding of energy emissions from black holes and blazars.

What challenges are associated with detecting neutrinos?

What are the implications of identifying a specific blazar as the source of a neutrino?
