01
Astronomy: what do we observe?
Positions, light, motion, and spectra help us describe objects in space. Leo’s sickle and the galaxies beyond it make a useful starting point.
THE LEONIS OBSERVATORY
Real stars.
Infinite questions.
Astronomy, astrophysics, and planetary science—with Leo as our window into the universe.
NEW / LEONIS COMICS EDUCATION
The sky awaits.
Discover the real Leo. Turn a star model sideways. Take the challenge. Bring a 14-page illustrated field guide to your classroom.

A CONSTELLATION IS A VIEW
The sky connects them.
Distance separates them.
Leo is a region of our sky, not one physical neighborhood. Its familiar star pattern and the much more distant galaxies seen in the same direction sit at very different distances.

Explore Leo, one connection at a time.
Regulus
Regulus marks the base of Leo’s sickle pattern. In Leonis, its realm connects Soularia, Luminara, and Heliara.
THE SCIENCE TOOLKIT
Ask better questions about space.
02
Astrophysics: why does it happen?
Gravity shapes stars and galaxies. Fusion supplies the energy of main-sequence stars. Light carries clues about temperature and composition.
03
Planetary science: what shapes a world?
A planet’s atmosphere, orbit, mass, and energy balance all matter. Receiving the right amount of starlight alone does not establish habitability.
MODELED / THE PLANET LAB
What if you changed the starlight?
Move the controls to compare incoming energy and a simplified equilibrium temperature.
SIMPLIFIED ENERGY BALANCE
Uniform heat redistribution, no greenhouse warming, and no internal heating. This is an equilibrium estimate—not a surface-temperature forecast or a life detector.
Model: relative flux = L / d²; T = 278.3 × [L(1 − A) / d²]¼ K. L is solar luminosities, d is AU, and A is albedo.
For an ocean world like fictional Trine, atmosphere and water circulation would also matter. Multiple moons would add tidal interactions that this simple model does not simulate.
NASA: The Habitable Zone ↗MODELED / LIGHT-YEAR EXPLORER
How long would the journey take?
A light-year measures distance. Try 30,000,000 light-years to explore the approximate scale of the Leo Triplet.
TIME IN THE DEPARTURE FRAME
Constant speed, ignoring acceleration and expansion of space. Massive spacecraft cannot reach light speed. A speed of 1c here describes light, not a spacecraft. Traveler time would require a separate relativity calculation.
Leonis portals are a fictional story mechanism, not an established transport technology.
