Galaxy’s

  1. 1. Galaxy’s Maija Beaudoin
  2. 2. The Milky Way <ul><li>The Milky way is a Spiral Galaxy </li></ul><ul><li>The phrase Milky Way came from the band of white light </li></ul><ul><li>The Milky Way is believed to be more than 13 billion years old </li></ul><ul><li>The Milky way’s circumference of roughly 250-300 th ousand light years! </li></ul>
  3. 3. The Milky Way <ul><li>In the main body of the Milky Way there are estimated to be between 200 and 400 billion stars </li></ul><ul><li>Scientists now estimate that in about three billion years, the Milky Way galaxy will actually collide with the Andromeda Galaxy </li></ul>
  4. 4. Irregular Galaxy <ul><li>An irregular galaxy is a galaxy with no rotational symmetry. </li></ul><ul><li>One way irregular galaxies are formed is when galaxies collide or come close to one another, and their gravitational forces interact. </li></ul>
  5. 5. The Andromeda Galaxy <ul><li>The Andromeda galaxy is the closest galaxy to the Milky Way. </li></ul><ul><li>It is also a si milar shape to the Milky Way, but four times bigger! I </li></ul><ul><li>It can be visible from Earth on a clear night if there are no lights nearby </li></ul>
  6. 6. 2 Galaxies Colliding <ul><li>In this picture, we can see two galaxies colliding. The smaller galaxy would be similar to The Milky Way in size if the bigger galaxy was the Andromeda Galaxy. </li></ul><ul><li>It is likely that the smaller galaxy is being attracted to the larger galaxy by the combined gravitational pull of the many billions of stars in its centre. </li></ul>
  7. 7. The Pinwheel Galaxy <ul><li>This galaxy is another Spiral Galaxy. We can see that it spins in an anticlockwise direction, showing us these spiral tails spinning around like a Catherine Wheel. These tails are very long and will take millions of years to return to the same spot that they are in now. </li></ul>
  8. 8. SOMBRERO GALAXY <ul><li>This galaxy is known as the Sombrero Galaxy because it resembles a Mexican hat. It has a large Galactic Centre and the stars in it appear to spin around it more like the rings of Saturn than the stars in a Spiral Galaxy. </li></ul>
