2011-07-26   Skinakas Observatory celebrates 25th anniversary

July 26, 2011

The Skinakas Observatory has been in existence for 25 years and this was celebrated end of May on top of the Ida mountains. Founded in 1986 by the University of Crete, the Foundation for Research and Technology Hellas FORTH and the Max Planck Institute for Extraterrestrial Physics, it is used both for the training of students and basic astronomical research.     more

Surprising Flashes from a possible Magnetar
Observations of optical flares reveal limits of established theories on magnetars

By means of the high-speed photometer OPTIMA of the Max Planck Institute for Extraterrestrial Physics (MPE), a team of MPE scientists might have detected an unexpected new sub-category of astronomical objects. It appears to be a magnetar with bursts in the visible part of the spectrum, in contrast to the X-ray and gamma flashes, which are considered to be characteristic for magnetars.
