Go beyond observation with calculations, celestial mechanics and hands-on astronomy articles.

Enter the Astronomy Lab

Software

Turn telescope images into measurements with tools built for practical astronomy experiments.

Discover the tools
Astronomy Lab

Don't just look. Work it out.

Use observations, simple physics and real astronomical data to understand what the telescope is showing you.

From photons to physics

Turn observations into measurements.

Why does the Moon look almost the same size as the Sun? How can orbital motion tell us a planet's mass? The Astronomy Lab turns real observations into experiments, calculations and physical insight.

Two telescopes, two views

Close-up planets. Wide-field deep sky.

The observing setup is chosen for the target rather than forcing one instrument to do everything.

Alan from Show Me The Sky
Why Show Me The Sky?

A lifelong fascination, shared live.

I received my first telescope at the age of ten. The first close look at the Moon — its craters suddenly becoming a real landscape — was the moment astronomy stopped being something in books and became something I could explore for myself.

Show Me The Sky is about recreating that feeling for other people: seeing a real object through a real instrument, asking questions as you go, and then understanding a little more about the physics behind the view.

Observing from a dark-sky area in Cornwall gives us access to both Solar System targets and deep-sky objects when conditions allow.

What participants say.

“J’ai observé la Lune en direct depuis mon canapé. L’équipe est passionnée et très pédagogue. Je recommande à 100%. ”

MarcFrance

“I never imagined learning astronomy from home could feel so immersive. The theory session helped me finally understand the solar system! Highly recommended.””

EmmaU.K.

“Cette session était formidable.”

Software

Turn images into measurements.

Tools created around practical astronomy workflows, from moon orbits and planetary mass to mapping telescope images on the sky.

Orbital dynamics

AstroFrame

Process Jupiter and Saturn observations, measure the motion of their main moons and use those measurements to explore orbital periods, distances and planetary mass.

Sky mapping

AstroMap Viewer

Plot telescope observations and FITS imagery against celestial coordinates so you can connect what appears in an image with its position on the real sky.
