Our radio telescopes can see invisible and hidden activities across the Universe and have solved some of the greatest mysteries of our Cosmos. We want to share our knowledge by supporting young and established scientists in collaborative research programs, mentor undergraduates in their research projects, enable student master projects and supervise students in obtaining their Ph.D. in astronomy. Explore what radio astronomy has in store for you.

Voor scholieren (Dutch only)


Wil je een spreekbeurt houden over radioastronomie? We hebben speciaal hiervoor een informatieblad gemaakt waarmee je alles over radioastronomie en radiotelescopen te weten komt.


Langs het voormalige kamp Westerbork, het Hingsteveen en de radiosterrenwacht loopt het Melkwegpad. Hier staan de fascinerende wereld van het heelal en de grootste radiotelescopen van Europa centraal.

For students

Summer Research Programme

The programme enables advanced undergraduate or graduate students in astronomy from around the world to carry out a summer research project.

Master Students

Students of both Dutch and non-Dutch universities can do a master project at ASTRON under the supervision of our staff.

PhD students and advanced-career scientists

PhD Opportunities

Students interested in obtaining a PhD in astronomy can do so under the supervision of ASTRON staff members.

Female Visitor Programme

As part of our commitment to equality and diversity, ASTRON and JIVE offer a visitor programme to young or established female scientists.

General information

What is Radio Astronomy?

Radio astronomy: a part of astronomy that studies the celestial objects by "capturing" the light that they emit.

What do Radio Astronomers see?

Radio astronomers can look at different elements on different wavelengths. If they study the same object using different wavelengths, they will obtain different images.


Here you find a selection of movies to tell you more about us.

How does a radio wave become a picture? Part III: Accelerators. LOFAR produces terabytes of data per second, how to process this? Supercomputers equipped with accelerators accelerate the calculations performed on the data. Read part 3 here:

Congratulations to our former colleague and LOFAR scientist Heino Falcke with his prize! 🥳

How does a radio wave become a picture? Part II: Compact receivers. A radio wave that has travelled light years is picked up by a receiver on a telescope through an antenna. The (very weak) signal is then amplified and digitized. Read part 2 here:

How does a radio wave become a picture? Planets, stars and nebula’s all emit radio waves, which are a form of invisible light waves. Read here the first part on what happens to those radio waves when they are received by a radio telescope! 📡🌠
