Dark matter, making up 27% of the universe, remains undetected directly. Instead, researchers study its effects through gravitational pull and infrared analysis. By examining galaxy rotations and behaviors, scientists track dark matter’s presence, revealing hidden forces that shape cosmic structures.
Infrared spectrographs on the Magellan Clay Telescope aid in detecting dark matter signals, separating them from background noise. Advanced detectors are also being used to isolate potential dark matter decay light, marking a significant leap in cosmic observation technology.
Recent studies have set new lifetime limits for dark matter particles, narrowing the search field and focusing future experimental efforts. Next-generation telescopes like James Webb will further push detection limits to reveal dark matter’s hidden form, bringing researchers closer to uncovering its secrets.
