NASA's Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy.
"What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center," said Doug Finkbeiner, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who first recognized the feature. "We don't fully understand their nature or origin."

A team of astronomers has found evidence that the universe may have gone through a warming trend early in its history. They measured the temperature of the gas that lies in between galaxies, and found a clear indication that it had increased steadily over the period from when the universe was one tenth to one quarter of its current age. This cosmic climate change is most likely caused by the huge amount of energy output from young, active galaxies during this epoch.
