Gravitational wave detectors: the universe ripples, they listen.
These detectors (LIGO
, TAMA300, AIGO) are listening for the gravitation waves: black holes spinning and colliding, or neutron stars inspiralling to their final fates in a black hole. [more inside]

On July 17th, NASA's Wide-field Infrared Survey Explorer
(WISE) satellite completed its first survey of the entire sky viewable from Earth
. After just seven months in orbit, WISE -- a precursor to the planned James Webb Space Telescope
-- has returned more than a million images that provide a close look at celestial objects
ranging from distant galaxies
. The first release of WISE data, covering about 80 percent of the sky, will be delivered to the astronomical community in May of next year
, but in the meantime we can see some of the images and animations that NASA has released to date: Galleries (containing just a small selection of images)
. Videos and Animations: 1

Black Holes Merge. Massive layoffs expected throughout galaxy.
Analysts predict big payoffs for the economy, however. "A burst of gravitational waves that could warp the very fabric of space will go a long way towards increasing shareholding value," said one economist. Both black holes had recently suffered a dramatic drop in stock price, and were under the threat of hostile takeover from industry leader Black Hole 86184-B before the merger was announced, which took Wall Street pundits off guard. "Much to our surprise, we found that both were active black holes," Stefanie Komossa of the Max Planck Astro-Economics Institute in Germany, said in a statement. Proponents of big business greeted the announcement with pleasure: "This supports the idea that black holes can grow to enormous masses in the centres of galaxies by merging with other black holes."

"Observing" other dimensions.
The existence of tiny black holes, produced by cosmic rays in the Earth's atmosphere, if confirmed by the Auger cosmic ray observatory
, might provide evidence for other dimensions beyond Space and Time.
Amazing how theories considered untestable by experiment a few years ago are turning into "real" science.
