Which celestial objects serve as famous examples of irregular galaxies orbiting the Milky Way?
Answer
The Large and Small Magellanic Clouds.
The Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) are the most notable irregular galaxies observable from the Southern Hemisphere. They exist as satellite galaxies to the Milky Way and are crucial for scientific study. Their structure and composition have been heavily influenced by the Milky Way's gravitational pull, resulting in the 'Magellanic Stream,' a trail of gas stripped from these galaxies, which provides astronomers with a real-world case study for observing tidal stripping and galactic interaction.
