In the context of the digitisation project of astronomical plates funded by the Deutsche Forschungsgemeinschaft (DFG) entitled “Digitalisierung astronomischer Fotoplatten und ihre Integration in das internationale Virtual Observatory”, a consortium of astronomers from the Hamburger Sternwarte, the L...
An international scientific team, including Prof. Dr. Manami Sasaki from Dr. Karl Remeis Observatory, Bamberg, and the Erlangen Centre for Astroparticle Physics has used NASA’s Chandra X-ray Observatory – one of the most sophisticated X-ray observatories built to date – to reveal how very high...
If you look up at the sky on a clear night you can see stars, lots of stars. Astronomical recordings from observatories let you see them in much greater detail. The Dr. Remeis Observatory owns approximately 40,000 historical photographic plates, a genuine treasure trove for anyone interested in star...
When a massive star ends its life it explodes in a very energetic explosion called a supernova. The ejected stellar matter expands spherically and is in some cases also collimated into jets. If a jet points to us, the explosion is observed as a very intense flash of gamma-ray emission...
In the middle of the large Chilean Atacama desert, a team of Polish astronomers monitors millions of celestial bodies night after night with the help of a modern robotic telescope. In 2013, the team was surprised when they discovered, in the course of their survey, stars that varied much faster...
A team of astronomers at the Friedrich Alexander University led by Péter Németh has discovered a binary star moving nearly at the escape velocity of our galaxy. There are about two dozen so-called hypervelocity stars known to be escaping the galaxy. While all of them are single stars, PB3877 is...
An international team, including NASA-funded researchers, using radio telescopes located throughout the Southern Hemisphere has produced the most detailed image of particle jets erupting from a supermassive black hole in a nearby galaxy. “These jets arise as infalling matter approaches the bla...
