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.
STORIES
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.
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.
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 Emanuela Orrù, support scientist at ASTRON since 2012.

Colloquium by Manuel Güdel: A fresh look at the environment of DG Tau
© Manuel Güdel
New JWST/MIRI observations reveal molecular lines of hot water and CO associated with the innermost protoplanetary disk; also, despite DG Tau’s youth, a substantial fraction of dust has grown to micron size. The jet system shows very strong infrared forbidden lines for which I will propose a direct link to the ~4 MK X-ray emitting plasma jet via shock heating and cooling. If successful, such a model will reveal more about the inner workings of the jet.
I will discuss shock models that involve collisional ionization and photoionization, shock self-radiation, recombination and charge exchange that are necessarily evolving away from collisional ionization equilibrium and therefore need to be evolved iteratively in time; I will address some diagnostic power of these models.
