Gamma Ray Galaxies
Issue: Galactic
Summary: Active galaxies are those with unusually bright centers that show evidence of particle acceleration to speeds approaching that of light itself. At the center of each active galaxy sits a feeding black hole weighing upwards of a million times the sun's mass. Through processes not yet understood, some of the matter headed for the black hole blasts outward in fast, oppositely directed particle jets. The researchers want to continue to monitor galaxies to examine any potential threats.
Opinion: From what I've learned in Earth Science, I know that any threats to Earth usually aren't coming for a long, long time. However, monitoring these dangerous light and gamma rays is crucial to potentially our planet's survival.
