Background

Hessdalen luminous phenomena have been recorded across multiple modalities, prompting targeted questions about their physical nature.

One enumerated open problem focuses on thermal constancy, self-containment, and color-dependent behavior observed in equal-sized spheres, which requires careful measurement and modeling to resolve.

References

The main open problems, which make the Hessdalen phenomenon an interesting subject for physics investigation, can be summarized as follows: 3. The constancy of temperature, the self-containment characteristics of the light balls, and the coexistence of white and red spheres of equal size.
