Simultaneous optical and radio observations of Perseids

From today (August 11th) up until Friday the yearly Perseids meteor shower will have its peak. This phenomenon is not only interesting for amateur astronomers, professional astronomers will be observing them as well.

Humans of ASTRON: Jorrit Siebenga

In Humans 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? In this second part of the series, we’ll be sharing the story of Jorrit Siebenga, who joined ASTRON in 2017 as research instrument maker.

Women Astronomers Day

Throughout the history of astronomy, women have played essential roles towards astronomical breakthroughs. In this article we highlight but a few of these women identified in history from 1600 to the modern era.

Congratulations to Dr. Ghidoni!

On Wednesday, March 18, Rebecca Ghidoni successfully defended her PhD thesis, “A New Window on the Ionosphere: A LOFAR Perspective, from Geomagnetic Storms to Statistical Trends,” at the University of Bologna. During her PhD, Rebecca spent part of her research period at ASTRON, where she investigated the ionosphere using LOFAR scintillation data.

She was fortunate that, during her doctoral research, Earth experienced the most intense geomagnetic storms in decades in May 2024, while LOFAR was actively recording. This provided a unique opportunity for one of her major studies on the May storm (see AJOID, 2024-11-26)

Her PhD was awarded cum laude.
