THE LAST TRANSMISSION / 3D ATLAS

There is more
than one direction.

Follow the signal through worlds and galaxies, descend into an ocean, then move inward toward cells and matter. Each scene opens a research file and shows where the evidence ends and the illustration begins.

01 / OUTWARD

Cosmic Maps.

Explore the observable neighborhood of galaxies, the Milky Way’s dark heart, and the worlds around our Sun. Each step changes scale; the scenes are independent models rather than one continuous flight.

02 / DESCEND

Habitats & Origins.

Between worlds and cells lies an environment where light, chemistry, and geology change with depth. Start with a guided Earth ocean descent; follow the separate evidence for other ocean worlds from there.

03 / INWARD

Living Systems.

Follow the hydrologic cycle, enter a rainforest ecosystem, then move inward to its cellular machinery. Compare a eukaryotic cell with a bacterium and explore the energy systems inside mitochondria and chloroplasts.

04 / INWARD

Matter & Quantum.

Start with an atom, then follow the three gratings that made a 7,000-atom cluster reveal its wave behavior. Then explore antimatter confinement and read the tracks left by a high-energy particle collision.

The Clyde Tombaugh and New Horizons documentary

CLYDE TOMBAUGH / NEW HORIZONS / WATCH & READ

The Man Who Made It To Pluto

A discovery became a destination. Follow Clyde Tombaugh, the memorial carried aboard New Horizons, and the people who revealed a world he never saw up close.

FIELD GUIDE / BLACK HOLES

The boundary that keeps
the universe outside.

Learn what an event horizon means, follow the difference between two falling clocks, and compare tidal forces around stellar and supermassive black holes. Original diagrams and a mass comparison connect the science to the Atlas.

FIELD GUIDE / OCEANS BEYOND EARTH

Three frozen worlds.
Three evidence trails.

Compare Europa’s magnetic response, Enceladus’s sampled spray, and Pluto’s competing interior models. Follow the measurements into the hidden-ocean question, the search for habitable conditions, and the Atlas.

Open Oceans Beyond Earth

FIELD GUIDE / HOW STARS DIE

The light changes.
The story continues.

Follow single stars and interacting companions into white dwarfs, neutron stars and black holes. Compare the physics of the endings with the observations that let us reconstruct a stellar life.

LIGHT LAB

What did the light
have to cross?

Move foreground galaxies to explore gravitational lensing, build a spectrum, measure parallax, or shift a source’s light to explore radial motion.

Enter Light Lab

SCALE LAB / THREE USEFUL COMPARISONS

Make the distance
mean something.

Compare black-hole horizons, calculate a signal’s travel time, and zoom from a cell toward an atom. Every tool shows its working and the assumptions behind its answer.

09 Model scope and predictions

Explore the model, then check its assumptions.

The Atlas lets you manipulate selected structures and scenarios. Its illustrations are designed to teach relationships, with scale and complexity chosen for that purpose. Repeating a screen experiment is useful for learning but is different from testing the world with additional observations.

Ask yourself Which assumptions drive this result, and where would the model stop being useful?
