NASA's Fermi Satellite Maps Entire Sky, Finds Mysterious Unknown Object

StartsWithABang writes: With the launch of the Fermi satellite in the late 2000s, we began observing the highest energy photons in the Universe — gamma rays — all over the sky, to unprecedented precision. Produced from cosmic ray showers in space when high energy protons run into other, stationary protons, these gamma rays locate point sources from supermassive black holes to supernova remnants to pulsars. There is, additionally, a great correlation between the infrared sky and the gamma ray sky, since the great high-energy background scatters off of the diffuse infrared gas, producing gamma rays there as well. But while a great many sources can be correlated with known structures, Fermi reveals at least one unknown, intense behemoth that emits spectacularly in gamma rays.

    Slashdot should not be accepting stories from some blogger who decides to simply re-link every single one of his articles for free Slashvertising without every contributing to the site, period. The shittyness of the resulting site not withstanding.

    Startswithabang has a post count of 1 and a submission count of 119.

    Not at all. All of his submissions however are to his own blogs. EVERY SINGLE ONE. This dates back before Forbes when he was peddling his clickbate on Medium.

    He has made 1 post in the past year.
    He has had 119 stories on the front page.

    He's not a shill, he's just someone using Slashdot as his own personal advertising platform.
