What are Galactic tides?

  • Like the earth’s oceans at their shores, the universe’s galaxies also experience tides, but on a much larger scale.
  • Galactic tides are caused by gravitational forces within a galaxy, arising in the interactions between celestial objects like stars and gas clouds.
  • These tidal forces influence various aspects of a galaxy’s evolution. They can reshape a galaxy structure by creating tidal tails and bridges, promoting star formation, and disrupting smaller star systems.
  • Over eons, galactic tides also disrupt the orbits of stars, leading to long-term changes in galactic structure. Galactic tides also have a say in the ways in which proximate galaxies do and don’t interact.
  • Research shows that Andromeda’s (galaxy nearest to our Milky way) tidal streams near its edges could be signatures of dwarf galaxies that were later devoured. The Andromeda galaxy is heading towards the Milky Way at 110 km/s and will collide in four billion years.
  • Galactic tides also affect the supermassive black holes at galaxy centres, leading to events that change the ways in which these cosmic beasts interact with nearby stars.
