Dark matter, which constitutes approximately 85% of the universe's mass, remains one of the greatest mysteries in astrophysics. It does not emit light, making it invisible and detectable only through its gravitational effects. Recent observations from NASA's Fermi Large Area Telescope have revealed an unexplained gamma-ray glow from the Milky Way's center, suggesting a possible link to dark matter. Additionally, studies of dwarf galaxies, which have fewer gamma-ray sources, have indicated potential signals of dark matter. Researchers are optimistic that upcoming instruments, such as the Vera C. Rubin Observatory and NASA's Compton Spectrometer and Imager, set to launch in 2027, will provide clearer insights. These telescopes aim to detect gamma rays produced by dark matter annihilation, potentially revealing its properties and origins. As scientists continue to explore the cosmos, they hope to answer fundamental questions about the universe's composition and the role dark matter plays in shaping it.
