Web11 apr. 2024 · (d) Galaxy UGC 10214 (“The Tadpole”) is a barred spiral galaxy 420 million light-years from the Milky Way that has been disrupted by the passage of a smaller galaxy. The interloper’s gravity pulled out the long tidal tail, which is about 280,000 light-years long, and triggered bursts of star formation seen as blue clumps along the tail. WebSpiral galaxies have a complex structure: a dense central bulge lies at the centre of a rotating disc, which features a spiral structure that originates at the bulge. Spiral galaxies are surrounded by sparsely populated halos — roughly spherical regions above and below the plane of the discs.
