Summary

Nutrition label

73% Informative

Dark matter accounts for 85% of the universe's total matter content.

It doesn't interact with light or "ordinary matter" so rarely that it is effectively invisible.

If dark matter is composed of hypothetical particles called axions, then there is a chance that these particles could "decay," breaking down into other particles.

This process could release photons, the particles that make up light, which JWST could then detect.

The shape of the spectral line created by axion decay could give scientists important information about the distribution of dark matter in our galaxy.

JWST 's investigation focuses on the decay of particles with masses between 0.1 eV and 4 eV.

Failure to make a detection could mean that the particles that comprise dark matter are outside this mass range.
