These representations of the albedo features recall some of the more detailed studies previously made at Pic du Midi Observatory
Using the high-sensitivity NARVAL spectropolarimeter installed at the Bernard-Lyot telescope at the Pic du Midi Observatory
in France, a team of astronomers detected the effect of a magnetic field (known as the Zeeman effect) in the light emitted by Vega.
Scientists at the world-renowned Pic du Midi observatory
in the Pyrenees say light from surrounding cities is preventing them from getting a good look at the heavens.
The researchers used instruments on the Canada-France-Hawaii Telescope atop Hawaii's Manna Kea and the Bernard-Lyot Telescope at the Pic du Midi Observatory
in France to record the polarization of light from the star and the magnetic splitting of spectral lines.
Brunier, an award-winning science journalist, and Lagrange, who is director of research at the French National Council for Scientific Research (CNRS), begin with a history of telescopes, followed by profiles of 36 land-based observatories, including the Pic du Midi Observatory
in France, the Cerro Tololo Observatory in Chile, the Parkes Radio Observatory in Australia, and the Narayangaon Interferometer in India.
