2012-06-27 13:04:31

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com Astronomers have uncovered a clever new way of studying the atmosphere of an exoplanet in more detail. An international team of astronomers used the European Space Observatory's Very Large Telescope to see the faint glow from the planet Tau Boötis b. For the first time, the team reported that it has been able to study the planet's atmosphere, and was able to measure its orbit and mass precisely. They wrote in...

Using the ESPaDOnS spectropolarimeter1 installed on the Canada-France-Hawaii telescope2 (Mauna Kea, Hawaii), an international team of researchers, led by two french astronomers (LESIA, Observatoire de Paris and LATT, Observatoire Midi-Pyr©n©es), has just discovered a magnetic field on tau Bootis, a star orbited by a giant planet on a close-in orbit: the first ever detection of this kind! Up to now, only indirect clues pointed to the presence of magnetic fields on stars hosting...

Longueuil -- Soon after its launch two years ago by the Canadian Space Agency (CSA), Canada's "Humble Space Telescope" started making amazing observations-beyond the capacity of any other Earth- or space-based instrument. MOST, our suitcase-sized space telescope orbiting at 820 km, can fix its gaze upon a single star for up to eight weeks at a time. And with its unique combination of steady observation time and precision pointing, MOST can look for subtle variations in stars that are...
