Something that needs to be considered relating to the size of the massive gamma ray emitting bubbles at the center of the Milky Way Galaxy is light lensing, \u2013 gravitational, and by many other wavelengths.\u00a0 This is because light bends light.<\/p>\n
Doug Finkbeiner of the Harvard-Smithsonian Center for Astrophysics and Harvard graduate students Meng Su and Tracy Slatyer \u201cmade the discovery while processing publicly available data from NASA’s Fermi Large Area Telescope (LAT).\u201d * \u00a0So as not to make assumptions, the three may have already considered light lensing, and the massive bubbles of the Milky Way may indeed be 50,000 light years across as published.\u00a0 If not considered, on the other hand, the bubbles may be smaller than thought, though still quite massive.<\/p>\n
As is already estimated by scientists, the bubbles volumetrically are mostly gas, with rocks, dust, stars, and other items intermixed in places.\u00a0 If scientists are spectrum analyzing for the gaseous elements present, that will be very interesting and we can all look forward to the results.<\/p>\n
