Just the daily post that makes me feel small and insignificant.

Is this a non-sequiter or just poorly phrased? > Disk galaxies like the Milky Way form stars “inside-out” — starting from the center and working outwards through the disk. So, as a general rule, the farther out astronomers look, the younger the stars are. Do they meant looking out from Earth (which is actually nearer to the center of a spiral arm than to either end) or out from the galactic bulge. Either way doesn't make sense.

Incredible. "Hi honey, what did you do at work today? Casually discovered the edge of the galaxy. How are you?"
