Astronomers Pinpoint Edge of Milky Way's Star-Forming Disk at 40,000 Light-Years

A good honest bake. Not flashy, but you'll finish the whole bagel.
Summary
Astronomers have identified the edge of the Milky Way's star-forming disk for the first time, determining that star formation is concentrated within 40,000 light-years of the galactic center. This finding supports the "inside-out" formation model of disk galaxies, where stars form progressively from the center outward, meaning stars farther from the center are generally younger.

Disk galaxies like the Milky Way form stars 'inside-out' — starting from the center and working outwards through the disk.
As a general rule, the farther out astronomers look, the younger the stars are.
