Massive Compact Halo Objects (MACHOs) are astronomical entities that are believed to reside in the halos of galaxies and contribute to the elusive dark matter component of the universe. These objects are typically massive, compact, and non-luminous, making them difficult to detect through traditional means, but their gravitational effects on surrounding matter provide indirect evidence of their existence. Their study is crucial for understanding the nature of dark matter and the structure of the universe.
