Our Galaxy has Weird Lobes - Yazata - Nov 4, 2018 Big, well-defined, spherical things above and below the center of the galaxy. Each one is about 25,000 light years across. https://nasa.tumblr.com/post/179690202529/blowing-bubbles-in-the-gamma-ray-sky They were never seen before now, because they are only visible in gamma-ray wavelengths. That fact suggests a very energetic process, and their position above and below the galactic center suggests (to me anyway) something to do with the giant black hole in the galactic hub. Maybe a less energetic analogue of the cosmic jets seen shooting out of some other galaxies' centers. NASA photo: This is a NASA photo of Centaurus A, an active galaxy, with light and x-ray wavelength photos superimposed. The similarity is close enough to suggest a similar source. Our galaxy's lobes are much more symmetrical though.
