The Helio House is a creative science-communication and outreach project dedicated to exploring the Sun, space weather, and our place in the heliosphere.

This site blends real space science concepts with games, visualisations, and experiments designed to make heliophysics accessible to everyone, whether you’re a student, educator, space enthusiast, or just curious about how the Sun affects life on Earth.

The Helio House, and its resident photon mascot Ray, are created and run by Dr. Waterfall, a heliophysicist and space-weather researcher.

Dr Waterfall is currently a heliophysicist at NASA, where her research focuses on how energetic particles travel through the heliosphere and how solar activity can impact space-based and ground-based technologies. Alongside her research, Dr Waterfall cares about science communication, education, and making complex space physics feel welcoming, visual, and fun.

Ray was created as a guide through the Helio House – a friendly way to introduce big ideas like solar storms, magnetic fields, and cosmic particles without needing a physics degree to follow along.

Questions, feedback, ideas, or collaboration thoughts are always welcome.
