You mean: life, as we know it…
Coruscant. A great summary description of average star distances from the center of the Milky Way, the middle (our neighborhood) and the back third of the outer edge. Enjoyed that Fraser mentioned the Milky Way halo is shaped more like a football as opposed to a sphere according to a recent paper. The concept that life on planets at the galaxy core may be difficult due to star density. Goldie Locks says this bed is too hard. Then stars near the edge lack metallic materials and may be difficult for life even though these stars do have planets. Goldie Locks says this bed is too soft. Then in the middle of the Milky Way that life habitability may be just right and this is where we live. The caveat that we are learning that life habitation is fuzzy gives us hope. Overall this is a Great explanation given this question is a very broad subject. I imagine graduate level courses could be taught on the subject. Great question and Great explanation Fraser.
