Reality ASM: the whole universe, in one map you can fly through.

Start at the planets on today's date. Zoom out past 12,000 real stars and all 88 constellations, across the Milky Way, through 11,000 named galaxies and the great walls and voids between them, to the edge of the observable universe. Every position comes from real catalogues and real physics. Then build a rocket, pour chemicals in a virtual lab, or graph any equation: Reality ASM computes it all.

The Universe Map

From the Sun to the edge of everything, without a jump cut.

One continuous map in five scales. Scroll to zoom from one to the next, tap anything to read about it, and switch names, constellations and layers on or off in Settings.

The Universe Map at the scale of the stars: over 100,000 stars with the constellation lines, nebulae and star clusters — Over 100,000 stars, 88 constellations, nebulae and star clusters

The Universe Map at the scale of the Milky Way, with its open clusters and globular clusters marked — The Milky Way with 6,500 open clusters and the globulars

The Universe Map at the scale of galaxies, with clusters, superclusters, walls and voids named — 11,000 galaxies, clusters, superclusters, walls and voids

Real cataloguesJPL orbital elements, the HYG star catalogue, OpenNGC, the Open Exoplanet Catalogue and Celestia's galaxy and cluster lists.

3,800 planetary systemsEvery star known to have planets, from Proxima Centauri at 4.24 light years outwards.

Real distancesFar objects sit at their comoving distance, worked out from their redshift with the same cosmology as the rest of the map.

Space Program

Build it from parts. Then fly it.

Design an engine from chamber pressure and nozzle size, stack stages, add strap-on boosters and a fairing, and launch on a real date from a real pad. The pad starts empty: build your own, or add PSLV, LVM3, Falcon 9 and the rest.

Real vehicles, real stages

PSLV-XL, GSLV Mk II, LVM3 and SSLV sit next to Falcon 9, Saturn V, SLS, Ariane 5, Soyuz and Long March 5. Each is built from its actual stages, so solid strap-ons burn out and drop away when they should.

To orbit, to the Moon, and home

Gravity, drag in a rotating atmosphere and the Moon's pull are integrated as you fly. The HUD tells you when the trans-lunar window opens and how close you'll pass the Moon.

Space company

Your satellites keep flying after you log off.

Found a company, buy a launch, and manage a fleet that lives in real time. Low orbits decay with drag; thrusters cost propellant; cameras need daylight.

Orbit decayDrag and Earth's oblateness act on every satellite, every day. Boost it or watch it re-enter.

CamerasPoint Cartosat-3 or EOS-05 at a place on Earth. Resolution follows the optics and the altitude.

Deep spaceFind the next launch window to Mars or Jupiter and send a probe. Check on it while it cruises.

Simulations

84 simulations in physics, chemistry and maths

Sorted by subject, with the most powerful first. Each one has an AI analyst beside it that sees the numbers on your screen.

Chemistry: a lab bench you can actually use

72 chemicals, glassware, a Bunsen burner, a burette and gas cylinders. Put things anywhere on the bench, lift a bottle over a beaker and it tilts and pours. The engine balances every equation and works out the heat, the pH, the colour and the gas.

The virtual chemistry lab: a bottle of sodium hydroxide pouring into a beaker of phenolphthalein that turns pink, while carbon dioxide bubbles from a cylinder into a flask

Mathematics: a sandbox for any equation

Type functions, circles, inequalities, points, polar and parametric curves, sliders and your own f(x). Roots, highest and lowest points and crossings appear by themselves, each worked out exactly by the engine.

The Maths Sandbox: a cubic f(x), a shifted copy, a shaded inequality and their roots and turning points

And many more

The Wave Interference simulation: two slits and the bright and dark bands they make on the screen — Two-slit interference

The double pendulum simulation, with the trail its tip leaves as the motion turns chaotic — Double pendulum

The Hydrogen Atom simulation showing the shape of an orbital in three dimensions — Hydrogen orbitals

The Molecule Shapes simulation with a molecule's bond angles marked — Molecular shapes

The titration simulation: a burette over a flask and the pH curve it draws — Acid and base titration

The fractal simulation, zoomed into the edge of the Mandelbrot set — Fractals

How it works

The browser draws. The engine computes.

Every number you see comes from a tested server-side tool built on NumPy, SciPy and SymPy. Your browser only animates the results. A few of the checks it has to pass:

pH 2.880.1 M acetic acid, from its Ka by solving the equilibrium exactly, not with the small-x shortcut.

C3 ≈ 9 km²/s²The best Earth to Mars departure in November 2026, found by solving Lambert's problem.
