Missions in Past Phase for How do planets, stars, galaxies and cosmic structure come into being?

How do planets, stars, galaxies and cosmic structure come into being? Missions for 'past' phase.

In order to understand how the Universe has changed from its initial simple state following the Big Bang (only cooling elementary particles like protons and electrons) into the magnificent Universe we see as we look at the night sky, we must understand how stars, galaxies and planets are formed.
