Galactic ecosystems encompass the varied complexes of inter-relating stellar, nebular, and other matter that are actively forming new stars. These include molecular clouds, cloud cores, protostellar and protoplanetary systems, HII regions and starbursts.
It is not hyperbole to state that galactic ecosystems have spawned pretty much everything that we hold dear – including ourselves. These nebular nurseries have incubated all the stars, planetary systems, and many of the complex molecules known to humanity.
More than fifty years ago, Apollo 15 photographed something unusual on the far side of the Moon. In a panoramic photograph taken from lunar orbit, two bright, sharply defined objects stood out from the otherwise subdued landscape on the floor of a crater called Paracelsus C.
Today we can take a much closer look.
By now, you have probably read or heard that our polluting ways have reached a critical point, where Earth is rapidly approaching total failure as a planet. Perhaps you have wondered how we humans could have managed to do so much damage in so little time.
Permanent settlements in space will require forms of localized government that are likely to differ from contemporary models of political order. This article thus asks a provocative question associated with the empirical record of human colonization and settlement in prior eras: What sort of authoritarian governance is most likely to form in human space settlements during the medium term?
