Researcher's Night i Hessdalen
The Østfold University College invites you to experience a night of science and mystery in Hessdalen on Friday, 25 September 2026.
We stream our cameras from the Blue Box live on YouTube, so you can see exactly what we record. We also create stacked images and make them freely available in our public Google Drive folder.

Welcome to Project Hessdalen
Collect data
Our goal is to capture measurable, verifiable data that can be shared openly with scientists and the public worldwide.
The Blue Box is the world’s first fully autonomous, multi-sensor anomaly detection system, continuously monitoring the Hessdalen sky since 1998.
Inspire research
Hessdalen offers a rare opportunity to study a persistent natural mystery with modern tools.
During the 1984 field study, 53 phenomena were documented with instruments ranging from cameras and radar to magnetometers and infrared viewers — sparking international scientific interest that continues today.

Create awareness
We share findings through public reports, livestreams, conferences, and educational outreach.
By making our data accessible and engaging the public, we aim to promote curiosity, critical thinking, and responsible research into unexplained aerial phenomena.
