Evidence for the Formation of Other Solar Systems

  1. We see stars forming throughout our Galaxy and in other galaxies.

  2. Newly formed stars show an excess of infrared radiation.

  3. In some nearby star forming regions the Hubble Space Telescope directly detects structures around young stars of just the right size and shape to be flat planet-forming disks.

     

  4. This various evidence for the presence of planet-forming disks persists for about 10 million years then disappears.

  5. Many older stars appear to be surrounded by very tenuous dust disks that may arise from continuing collision between larger bodies (e.g. asteroids) which have formed previously.


    But Most Importantly of All...
