Free from the atmosphere

An artificial, laser-fed star now shines regularly over the sky of ESO's VLT. This system provides assistance for the adaptive optics instruments on the VLT and so allows astronomers to obtain images free from the blurring effect of the atmosphere, regardless of the brightness and the location on the sky of the observed target. The system has now delivered its first scientific results, which prove to be unique.

4. Space Weather Gear Readied For The Final Frontier
   09-29-2006 · ScienceDaily
   Atmospheric outflows, auroral emissions and plasma winds? While those aren't terms we hear on the average weather forecast, they cause cosmic storms that rage just outside the Earth's atmosphere and often wreak havoc with telecommunications networks, power grids and other technology essential to Canadian society. Researchers are hoping to gain a better understanding of this "space weather" with a suite of scientific instruments being developed under the leadership of the University of Calgary's Institute for Space Research.

   02-23-2007 · EurekAlert!
   Comet McNaught, the Great Comet of 2007, has been delighting those who have seen it with the unaided eye as a spectacular display in the evening sky. Pushing ESO's New Technology Telescope to its limits, a team of European astronomers have obtained the first, and possibly unique, detailed observations of this object. Their images show spectacular jets of gas from the comet spiralling several thousands of kilometres into space, while the spectra reveal the presence of sodium in its atmosphere, something seen very rarely.
