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.

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.
Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history. Significant changes in the quasar’s emission give a new perspective on the inner workings of quasars and how they interact with their environment. The study was led by Dr Elias Kammoun, a postdoctoral researcher at the…
When stars like our Sun use up all their fuel, they shrink to form white dwarfs. Sometimes such dead stars flare back to life in a super-hot explosion, called a “nova”, and produce a fireball of X-ray radiation. Using the eROSITA telescope on the SRG space observatory, a research team led by Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)…
Using the SRG/eROSITA all-sky survey data, scientists at the Max Planck Institute for Extraterrestrial Physics have found two previously quiescent galaxies that now show quasi-periodic eruptions. The nuclei of these galaxies light up in X-rays every few hours, reaching peak luminosities comparable to that of an entire galaxy. The origin of this…
Gigantic hot-gas structures above and below the galactic disc are probably due to shock waves generated by past energetic activity in the center of our Galaxy.
A study led by Alejandra Yrupe Fresco (Max Planck Institute for Extraterrestrial Physics) during her stay at the Instituto de Astrofísica de Canarias (IAC) has revealed the dim core and the jet structure in the nuclear region of M87, the brightest galaxy in the Virgo cluster. The observations were acquired in early April 2017, almost simultaneously…

Launched from Baikonur on July 13th 2019 to the second Sun-Earth Lagrange point (L2), the Russian-German SRG mission has now started its main task. On December 8th, after an extensive program of commissioning, calibration and performance verification of its two X-ray telescopes (ART-XC and eROSITA), the satellite has begun observing the sky in…
