  I'm someone who's endlessly fascinated by the--well--endlessness of space. Or maybe it's not endless. Maybe it's beginning is closer than we'd imagined. I really enjoyed urlLink this piece about the latest (and deepest) images received from the Hubble Telescope. The notion that when we look at far-away galaxies, we're essentially looking back into time never quite dawned on me until now. Pretty interesting stuff.
