At the 227th meeting of the American Astronomical Society in Kissimmee, Florida there was a presentation of significant improvements that NASA obtained to the performance of its Fermi Gamma-ray Space Telescope. The data collected by its Large Area Telescope (LAT) instrument were analyzed again in what was called Pass 8 with a new software. That allowed to discover new gamma ray sources that previously weren’t identified. At the same time it was possible to improve the ability of the LAT to determine the direction of the incoming gamma rays.
