It is up to 400 light-years deep and 9,000 light-years long, undulating nearly a tenth of the way across the Milky Way's diameter. At its closest to us, the wave is just 500 light-years away.

Spanning about 9,000 light-years (or about 9% of the galaxy's diameter), the unbroken wave of stars begins near Orion in a trough about 500 light-years below the Milky Way's disk. The wave swoops ...
