      The Andromeda Galaxy is the closest large galaxy to the Milky Way and is one of a few galaxies that can be seen without a telescope from the Earth.

      Andromeda has numerous satellite galaxies, including 14 dwarf galaxies that it regularly bullies.
      Both M32 and M110 have had encounters with M31 that they’ve come off worse from: a stream of stars was ripped away from M110 while Andromeda robbed M32 of a large part of its stellar disk at some point in the distant past.

      I’m not sure if science has gotten that far yet, at least in detail. Though in or own galaxy the milky way there was a mission called the Kepler mission which launched in 2009 to find terrestrial planets (those one half to twice the size of the Earth), especially those in the habitable zone of their stars where liquid water and possibly life might exist.

      The Kepler Mission, NASA Discovery mission #10, was specifically designed to survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets.

      Based on how many the Kepler mission found in the Milky way http://kepler.nasa.gov/Mission/discoveries/ I would say that there probably are planets like Earth in the Andromeda galaxy too, we just don’t know a lot about them yet.

      Planets have something in common… they are “spherical”…
      It is difficult to say at moment if there is one planet like Earth in Galaxy Andromeda… in terms of size, it would be difficult, but who knows….
      The questions following this, would be, if they find one:
      can we live on it? is there oxygen?
      Is there a source of life? (bacteria, grass.. other type?)

      We don’t know yet!

      We should probably send out an expedition to Andromeda to find out (although it would take them millions of years to get there even at the speed of light).

      We do know that Andromeda has stars a lot like our galaxy, and we know that our galaxy’s stars have planets, so I’d guess the answer is yes.
