IRF contributes to our knowledge of space

As a state-owned research institute, IRF works in a variety of ways to spread knowledge about space and our research. Interest in space activities from schools, the general public and the media is high.

Teachers may need material for their students. Teenagers who are interested in space seek information about IRF and the things it studies. Tourists want to see the Northern Lights in real time or are interested in what the Northern Lights really are.

IRF wants to promote and encourage everyone to learn more about space. Each visitor’s needs are different so we hope that you find what you are looking for below.
