Galaxy at the Edge

Spiral galaxy NGC 4921 
Spiral galaxy NGC 4921 presently is estimated to be 320 million light years distant. This image, taken by the Hubble Space Telescope, is being used to identify key stellar distance markers known as Cepheid variable stars. The magnificent spiral NGC 4921 has been informally dubbed anemic because of its low rate of star formation and low surface brightness. Visible in the image are, from the center, a bright nucleus, a bright central bar, a prominent ring of dark dust, blue clusters of recently formed stars, several smaller companion galaxies, unrelated galaxies in the far distant universe, and unrelated stars in our Milky Way Galaxy.

"We are a way for the cosmos to know itself." - Carl Sagan. 

Contemplate this at ANY time of the day or night, whatever you are doing - and you may find some relaxation from the stress...It's a never-ending train of thought as to what it means to be the cosmos in human form - and vice versa. For me, it helps to see the Earth in its wholeness and that impacts my thinking on everything. Caroline Webb, Quote - Facebook
