Scientific Description
Launched in 2006 by astronomers at Aarhus University and the University of Copenhagen, SONG is a Danish-led RI dedicated to the design and construction of a global network of small telescopes for the study of stars and planetary systems around stars. The idea is to develop an inexpensive, ultramodern robotic telescope that would provide maximum scientific impact for the cost and be scientifically unique even before the completion of the entire planned globe-spanning network of eight telescopes.A prototype of the first telescope, financed by Danish sources, has now been erected and tested at the Teide Observatory on Mount Izaña in Tenerife. At just 1 meter in diameter, the telescope is much smaller than many modern telescopes – it is the instrumentation and the possibilities offered by the eventual network that sets SONG apart. The technical equipment, installed in an adjacent shipping container, can all be controlled remotely via an ordinary Internet connection. The facility cost DKK 30 million, significantly less than many of the other new facilities around the world.The scientific goals of SONG are:1) to study the internal structure and evolution of stars using asteroseismology.2) to search for and characterize planets with masses comparable to the Earth in orbit around other stars.
