Title: "Astronomers find the edge of the Milky Way"

First sentence in the article: "Astronomers have located the edge of the Milky Way’s star-forming disk for the first time"

Wouldn't you expect someone from a publication called "Sky & Telescope" to know that these two are different things?!

Also, in diagrams showing our galaxy, I would greatly appreciate a "you are here" marker which points out the location of our solar system...

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.

How are claims like these verified?

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

I'm still searching for the location of the Restaurant at the end of the universe.

Oh thank goodness, I've been looking for that.

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

Looks like leaving the solar system was just the tutorial level。 Next main quest:breaking out of the Miky Way.
