Issue: Galactic


Summary: "Now, astronomers using NASA's Fermi Gamma-ray Space Telescope find themselves in the same situation as cartographers of old. A new study of the ever-present fog of gamma rays from sources outside our galaxy shows that less than a third of the emission arises from what astronomers once considered the most likely suspects -- black-hole-powered jets from active galaxies." But if active galaxies aren't emitting this gamma radiation what is? Stars that have the properties that enable them to do "Particle acceleration" may be responsible for so much gamma radiation, but scientists are still searching.


Opinion: With all these gamma rays, what will the impact be on Earth? And if the stars are emitting the radiation, could the sun potentially overthrow our magnetic field which guards us from these rays. Further research should be conducted to find out how this is impacting us and our understanding of the galaxy.
