This is the second article in a series of four articles each with a separate explanation of different quantum phenomena. Each article is a piece of a mosaic, so every one is needed to understand the final explanation of the quantum astronomy experiment we propose, possibly using the Allen Array Telescope and the narrow-band radio-wave detectors being build by the SETI Institute and the University of California, Berkeley.

PPARC -- A mystery lurking at the centre of our own Milky Way galaxy - an object radiating high-energy gamma rays - has been detected by a team of UK astronomers working with international partners.     Their research, published today (September 22nd) in the Journal Astronomy and Astrophysics, was carried out using the High Energy Stereoscopic System (H.E.S.S.), an array of four telescopes, in Namibia, South-West Africa...

Chandra X-Ray Observatory -- Astronomers have used an X-ray image to make the first detailed study of the behavior of high-energy particles around a fast moving pulsar.     The image, from NASA's Chandra X-ray Observatory, shows the shock wave created as a pulsar plows supersonically through interstellar space...

UC Davis/- The recent crash of NASA's Genesis space probe may have looked like bad news for scientists, but its cargo of particles captured from the sun should still yield useful information, according to Qing-Zhu Yin, a planetary scientist at UC Davis.     Yin, who is not directly affiliated with the Genesis mission, studies the composition of meteorites to learn about the formation of the solar system...

'No one could have expected so much unexpectedness' Topflight astrophysics boffins believe they may have cracked the tricky problem of how to make antimatter, which would be useful for many purposes: for instance powering relatively practical starships, or - of course - blowing up an entire planet in one go. However, it appears that making antimatter requires the possession of a black hole or a neutron star, so it won't be happening any time soon.â¦
