Gamma-rays have previously been highlighted as a possible result of dark matter annihilation. But if gamma-rays are the result of particles accelerated by pulsars, they may not be evidence of dark matter.through the Fermi bubbles and is marked by elongated streams of gas and stars that were ripped from the galaxy's core as its tight orbit threaded it through the disk of the Milky Way.
Gamma-ray emissions are thought to be created by young stars, by dark matter annihilation or by millisecond pulsars. This violent gas removal means that the Sagittarius dwarf galaxy is no longer formingFurthermore, the shape of the Fermi cocoon closely matches the observed distribution of visible stars, ruling out dark matter as a source of the emissions. .
This still from a NASA animation depicts the super-bright and super-young pulsar J1823-2021A, which is the brightest and youngest pulsar yet discovered, and has a powerful magnetic field. The pulsar spins about The object pulses 183.8 times a second and is located about 27,000 light-years from Earth.
"We are satisfied there is only one possibility: rapidly spinning objects called 'millisecond pulsars,'" the team wrote in an Australian National University
Que lindo!!!

Wow!
Ya see what I mean ?
Funny how much it resembles the Disc/Saucer part of StarTrek's Enterprise. Wouldn't you agree ?
Denny's charges people who know 'Dead stars in Milky Way's companion galaxy cause mysterious gamma-ray cocoon' 2 bucks for a cup of coffee while they charge everybody else 2 dollars.
