Galactic structure

The Milky Way

Fly through a detailed 3D barred spiral: a warm stellar bulge, winding arms, dust lanes and star-forming clouds.

THE PHYSICS

A closer look.

Logarithmic spiral ridges illustrate the shape of the arms; this is a structural visualization.

r = r₀ exp(θ tan p)

G is the gravitational constant, M and m are masses, r is separation, c is the speed of light, and b is impact parameter where applicable.

What you can learn

  • Compare face-on and edge-on galactic structure
  • Locate the Sun relative to the galactic center
  • Create cinematic fly-throughs with timed camera moves

Default bodies

Fixed Sagittarius A* and Sun markers, plus up to 122,200 visual star, gas and dust samples

KNOW THE MODEL

Procedural approximation informed by ESA's descriptions of galactic anatomy. Arm locations, colors and clouds are illustrative, not Gaia observations. Markers are fixed; no galactic dynamics, dark-matter solver or individual stellar orbits.

Space fabric illustrates gravitational influence; it is not a numerical solution of the full Einstein field equations. Visual sizes can be enlarged independently of physical collision radii.

Keep exploring.
