Another view of our Home from Gaia: This from the Top Down (APOD)

Yesterday's Astronomy Picture of the Day showed a side view of our Home Milky Way Galaxy as reconstructed from a 3D model derived from data collected by the Gaia telescope over this past decade or so.

Today's has a View from the Top.
