An international team of astronomers has produced the largest and sharpest map of the sky at ultra-low radio frequencies, using the Low Frequency Array (LOFAR) radio telescope. The map published in the journal Astronomy & Astrophysics reveals more than 25,000 active supermassive black holes in distant galaxies.
STORIES
In People of ASTRON we share stories about the people at ASTRON. Who are the people behind the discoveries and innovations and also, who are the people that make sure that everything runs smoothly? Design engineer Paula Fusiara has been working at ASTRON since 2016.
The SKA Observatory, a new intergovernmental organisation dedicated to radio astronomy, was launched today following the first meeting of the Observatory’s Council.

The maps are published as part of PDOK ("Publieke data op de kaart") and are available in various forms - such as WMS - under a CC-BY 4.0 license. They can be viewed online for the whole of The Netherlands at PDOK viewer: choose 'Selecteer een dataset', add 'Overige kaarten / Luchtfoto's / Luchtfoto (25cm) 2020'. The 2020 map is not available there yet, I used QGIS with the PDOK plugin to get direct access to the underlying WMTS server.
Apart from being nice desktop backgrounds, these photos could help in validating antenna positions and assessing the state of some antennas. The orthophotos are of high quality and the positions should be accurate to a few cm.
EVENTS
Applied RF technology course
Mon 17 May 2021 - Thu 20 May 2021
The RF course is an excellent introduction for Digital / Analog engineers who are or will be involved in the development of RF systems.
