Ganymede: A Giant Radar for Detecting Dark Matter?
Scientists propose using Ganymede, the largest moon of Jupiter and the largest natural satellite in the solar system, as a kind of giant “radar” to detect dark matter.
Dark matter is notoriously difficult to find because it does not emit or reflect light. However, astrophysicists believe in its existence due to the gravitational force it exerts on galaxies and galaxy groups.It is estimated that dark matter forms about 27% of the universe’s content, far exceeding ordinary matter, which makes up only 5%.
The challenge lies in the mysterious nature of dark matter particles. Many candidates exist, ranging from light particles like axions to massive objects like mini black holes. Direct detection efforts have so far been unsuccessful.

According to research published on Arxiv, titled “Dark Wounds on Icy Moons: Ganymede’s Subsurface Ocean as a Dark Matter Detector,” Ganymede could be a natural place to find traces of dark matter collisions. The moon has a very thick ice layer and is relatively…

FAQ
- What is dark matter? Dark matter is a hypothetical form of matter that does not interact with light, making it invisible to telescopes.
- Why is Ganymede a good place to look for dark matter? Ganymede’s icy surface could potentially record collisions with dark matter particles.
