This is a series of four articles each with a separate explanation of different phenomena. Each of the four articles is a piece of a mosaic and so every one is needed to understand the final explanation of the quantum astronomy experiment we will be proposing to do 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.

To explore deeper into our solar system, maximum efficiencies may one day be extracted from sound waves. Los Alamos scientists have engine plans drawn up for making a big bang to push a pistonless drive forward.

Astronomers sifting through  the radiation signals emanating from a distant black hole have separated the  emission into its two component parts, a key step in understanding how such  massive objects work.

Three powerful blasts from three wholly different regions in space have left scientists scrambling. The blasts, which lasted only a few seconds, might be early alert systems for star explosions called supernovae, which could start appearing any day now.

NASA astronomers last month detected two X-ray blasts and an almost-gamma ray burst that could be signs of imminent supernovae. The X-ray flashes came on 12 and 16 September, followed on 24 September by something

News from the galactic centre Astronomers using ESA's Integral gamma-ray observatory have spotted a massive eruption of gamma rays in the galactic centre. The researchers say the characteristics of the flare indicate that it could be an extremely rare star-black hole binary system, exhibiting behaviour that might only be seen once or twice in a decade.â¦

Scientists were startled when they discovered in 2004 that the center of our galaxy is emitting gamma rays with energies in the tens of trillions of electronvolts.
