Milky Way Explorer

This model needs WebGL to draw in three dimensions. The same galaxy is drawn flat here, and every number is under Readings.

Drag to turn the model, scroll or pinch to zoom, tap a name to go to it. With the model focused, the arrow keys turn it, plus and minus zoom, Space plays or pauses, the square brackets step the clock, Home returns to the chosen view.

Every quantity the model rests on, with its class and its source. The drawing is scaled from these; it never changes them.

Schematic geometry on sourced dimensions: the stars are a seeded drawing, not a catalogue, and the bubbles are smooth outlines of ragged structures, drawn symmetric although the northern eROSITA bubble is the brighter.
