German astronomers finish Europe’s largest solar telescope on Tenerife

German astronomers finish Europe’s largest solar telescope on Tenerife

by Kerstin Mork last modified Sep 15, 2014 12:17 PM

15 May 2012. After ten years of development, the new German solar telescope GREGOR will start operating at the Spanish Observatorio del Teide of the Instituto de Astrofísica de Canarias on Tenerife. It is the largest solar telescope in Europe and number three worldwide. It will provide the German and the international community of solar physicists with new and better instrumentation which will enable them to investigate our home star in unprecedented detail.

30 March 2012. The Sloan Digital Sky Survey (SDSS-III) today announced the most accurate measurements yet of the distances to galaxies in the faraway universe, giving an unprecedented look at the time when the universe first began to accelerate. From different perspectives six publications, which have been published online now, address the question of “Dark Energy“, the unknown force that drives our Universe apart.

Gaseous ring around young star raises questions

Gaseous ring around young star raises questions

18 January 2012. Astronomers have detected a mysterious ring of carbon monoxide gas around the young star V1052 Cen, which is about 700 light years away in the southern constellation Centaurus. The ring is part of the star’s planet-forming disk, and it’s as far from V1052 Cen as Earth is from the sun. Discovered with the European Southern Observatory's Very Large Telescope, its edges are uniquely crisp.

7 December 2011. In the current issue of "Nature Communications" from Dec 06, 2011 physical chemists at University Potsdam and astrophysicists at the Leibniz Institute for Astrophysics Potsdam (AIP) in collaboration with colleagues from Sydney / Australia describe their latest results obtained within the ASPIC consortium (Astrophotonics and Instrumentation Consortium): a complex multi-notch optical filter that allows for observations of faint stars and galaxies by suppression of bright infrared night sky.

400 years of research in sunspots

400 years of research in sunspots

by Gabriele Schoenherr last modified Jul 14, 2011 09:18 AM

21 June 2011 - The first scientific article about sunspots was published 400 years ago on 23 June 1611. Scientists of the Leibniz Institute for Astrophysics Potsdam (AIP) and the University Oulu in Finland are now reconstructing tens of thousands of sunspots: the solar activity over four centuries. Looking back on history, they also want to understand better the future of the activity of the Sun.
