What does the term "DSO" stand for in astronomy?

The term "DSO" stands for "Deep Space Object" in astronomy. This designation refers to celestial objects that are located outside of our solar system and are typically observed in the deeper regions of space. DSOs include a variety of astronomical phenomena such as galaxies, nebulae, clusters of stars, and other entities that can be seen at significant distances from Earth. The study of these objects is crucial for understanding the structure and evolution of the universe, as they provide insights into the formation of stars, the behavior of materials in space, and the overall dynamics of cosmic systems.

While the other options suggest potential meanings for "DSO," they do not accurately reflect the commonly accepted terminology in the field of astronomy. "Distant Stellar Object," "Dynamic Solar Object," and "Dark Star Object" do not align with the established use of the acronym in astronomical literature and discussions. Thus, "Deep Space Object" is the recognized term when referring to these distant celestial entities.
