We are nearing the end of a golden age of astronomy as more than a dozen space observatories reach their end of life in a few years. The only replacement on the horizon is the James Webb Space Telescope, scheduled to launch in 2014. Due to its enormous complexity and ever-rising costs, the JWST has starved other projects of funding. The fate of an entire generation of cosmologists and astrophysicists rests on its success.

Mysterious New 'Dark Flow' Discovered in Space. "As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon 'dark flow.' The stuff that's pulling this matter must be outside the observable universe, researchers conclude." [more inside]

The Pioneer Anomaly. Something's up in deep space: the Pioneer spacecraft, now out of contact, have shown an unexplained Doppler drift, indicating sunward acceleration, effectively decelerating the probes cumulatively. The effect may be be nongravitational, and could be explained by any number of factors: an undiscovered twist in Newtonian physics, localized cosmological contraction issues, or just venting gas. Other deep space probes may have experienced the anomaly as well, and a new mission could explore the puzzle; but for now, all we have is past Pioneer data, and that's stored on old 9 track tape which can only be read by antique readers. What's to be done? (Also see Pioneer Odyssey for a nostalgic romp through those early days of deep space exploration. And NASA, bring back the original Pioneer home page plz, kthx.)

Massive explosion rocks NASA And Pasadena, and a few other places, too. It's not every day you get to watch a black hole form. Includes cool animation (.mov file). Seems the gamma ray burst detector picks up two or three significant events every month or so.

When NASA scientists watch Michael Bay films, comedy ensues. 'The technology is not at all far-fetched,' said Dr Greg Laughlin, of the Nasa Ames Research Center in California. 'It involves the same techniques that people now suggest could be used to deflect asteroids or comets heading towards Earth. We don't need raw power to move Earth, we just require delicacy of planning and manoeuvring.' Oh yeah, nothing could possibly go wrong with this plan. I'm not being a Luddite here...I realize the scientists involved aren't going to be doing this any time soon, if ever. It still spooks me, though.
