Astronomers Heino Falcke of Radboud University and Sheperd Doeleman of the Harvard-Smithsonian Center for Astrophysics will jointly receive the Henry Draper Medal for their pioneering work, which led to the first image of a black hole.
The EHT team that published the first images of the shadow of a black hole last year used the knowledge they gained to analyse archive data from the period 2009-2013 and concluded that the shadow has been wobbling across the years.
The international team of researchers that previously captured the first image of a black hole has now discovered a corkscrew-shaped jet of plasma near a supermassive black hole in a galaxy in the Virgo constellation. The researchers, including several Dutch astronomers, will publish their findings on 7 April in the Astronomy & Astrophysics journal.
When a black hole chews up a star, we see this either in visible light or in X-rays, but almost never through both types of radiation. Astronomer Peter Jonker and his colleagues have now spotted a number of captured stars with an X-ray telescope, a few years after they were discovered in optical light. It appears that black holes all dine in the same way after all, while the mood lighting varies according to a fixed pattern.
The Event Horizon Telescope team that managed to take the first image of a black hole, has won the Breakthrough Prize in Fundamental Physics 2020. Astrophysicists at Radboud University played an important role in the project.
Astronomers have just managed to take the first image of a black hole, and now the next challenge facing them is how to take even sharper photos. Radboud University astronomers are putting forward a concept for achieving this by launching radio telescopes into space.
For the first time, astronomers have managed to take a photo of a supermassive black hole and its shadow. They used the Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes, that together form a virtual telescope the size of the earth. The news was presented in six press conferences around the world simultaneously.

The Netherlands Research School for Astronomy (NOVA) will travel from 27 March to 3 April 2019 with the Mobile Planetarium through Namibia to visit schools in remote areas. The project is part of Radboud University's and University of Namibia’s (UNAM) outreach plans for the Africa Millimetre Telescope (AMT) that will be constructed at the Gamsberg summit in Namibia as part of the Event Horizon Telescope.
