Astronomers have traced the source of a mysterious giant cloud of antimatter surrounding the galactic centre of the Milky Way galaxy, to binary star systems.
The discovery took four years of observations from the European Space Agency's Integral (International Gamma-Ray Astrophysics Laboratory) satellite.
What the satellite found was that the cloud of antimatter extends farther on the western side of the galactic centre than it does on the eastern side.

Interesting stuff :)

Thank you. ;)

shit

shit
shit?

shit?

translation from slang Australian "awesome"

wait so...antimatter releases gamma-rays? and thats how it is detected?

Sagittarius A binary star ...

yeah true draqon awesome
and thats fairdinkum

So the theories about annihilation of neutralino dark matter in the galactic centre, darkmatter engines, etc, etc are effectively dead.

It's merely a hyphothesis based on estimate data.

I suppose considering that we can produce tiny quantities of anti-matter by similar processes on Earth, we should not be suprised that sometimes whole planets worth of material moving at near light speed can produce huge quantities of anti-matter?

Legions of tiny black holes created during the big bang may lurk at the centre of the galaxy, creating a prodigious antimatter factory, a new study suggests. The work could explain where the Milky Way's antimatter comes from one of the biggest mysteries in astrophysics.

The Compton Gamma Ray Observatory, Integral, and Swift perhaps? Gamma Ray Bursts have been an ongoing mystery to astronomers, and when they have a mystery, they make instruments to help solve it.

shit?

Anti-shit probably..

Gamma Ray Bursts have been an ongoing mystery to astronomers.

Interesting,

But, to keep the thread on topic, it is not related to the vast lopsided cloud of antimatter that has been traced to binary stars.

Indeed not, but as usual Dragon was showing his usual ignorance. I just wanted to point out there there have been several instruments made to detect Gamma rays.

I've been saying this for years... Antimatter could under the correct conditions be pushed away from each other during photon-creation! This is very interesting stuff.

Good to see , that my tax money to ESA , has not been wasted !!!
We have ofcourse been producing positrons (antimatter) for years here on earth .........we use it every day in the hospitals for PET-scanning !!!

I still remember long hours waiting for the isotopes to arrive from Germany , so we could start the scanning for my research projects .......

It's terribly fascinating but so far nothing conclusive. Thanks I'll be digging for more on this.

Additional:
The cloud is MASSIVE 10,000 light years across. No wonder it's detecable from Earth and Generats the Energy of 10,000 suns! There might be something to the generating of positrons from the binaries but if binaries are the typical in our galaxy jand the most stable unit then this should be occuring even in other galaxies especialy those with supermassive black holes at there center (most major galaxies)
