The Milky Way galaxy is reportedly exhibiting a significant ripple effect that extends across at least a quarter of its disc. If validated, this intriguing structure may be a remnant of a close encounter with another galaxy, though some astronomers remain skeptical about its existence.
Common representations of the Milky Way depict it as a flat disc with a central bulge; however, its actual structure is much more intricate. Recent studies have revealed the presence of undulating clouds of stars and gas, generating waves across various sections of the galaxy. Further investigations are ongoing to uncover more about this fascinating phenomenon.
