NASA's Fermi Links Cosmic Neutrino to Monster Black Hole

The Ray Space Telescope identified a high-energy neutrino source from a blazar, a type of galaxy with a supermassive black hole. This neutrino, after traveling 3.7 billion years, was detected in Antarctic ice, producing a Muon tracked by the Ice Cube Neutrino Observatory. NASA's Fermi Gamma Ray Space Telescope confirmed the blazar as the source, marking the first time a neutrino was traced to a black hole. This discovery is a significant step in Multi-Messenger Astronomy, which combines light, gravitational waves, and neutrinos to study cosmic phenomena.

What type of galaxy was identified as the source of the high-energy neutrino?

• Elliptical Galaxy

• Blazar

• Dwarf Galaxy

• Spiral Galaxy

What particle was produced when the high-energy neutrino struck an atom in Antarctic ice?

• Photon

• Muon

• Proton

• Electron

Which observatory tracked the muon created by the neutrino collision?

• Hubble Space Telescope

• IceCube Neutrino Observatory

• Very Large Telescope

• Chandra X-ray Observatory

What did NASA's Fermi Gamma Ray Space Telescope discover about the blazar when the neutrino arrived?

• It was brighter than it had been in a decade

• It was moving away from Earth

• It was dimmer than usual

• It had disappeared

What is the significance of tracing a neutrino back to a black hole?

• It marks the first time a neutrino is linked to a source beyond our galaxy

• It shows black holes emit visible light

• It confirms the existence of black holes

• It proves neutrinos travel faster than light
