The Hidden Cosmos: Exploring the intriguing world of dark galaxies

The recent discovery of dark galaxies, galaxies with sparse and faint stars, challenges conventional views on the formation and evolution of galaxies. Astronomers have found a galaxy composed solely of gas, unable to form stars due to its diffuse nature. Another small dark galaxy, named Nube, has stars spread thinly across a large volume. These findings offer insights into the nature of dark matter, which makes up most of the universe. The existence of dark galaxies prompts a reevaluation of the definition of a galaxy. Further research is needed to understand these discoveries fully.
