Robin Kingsburgh Modern telescopes reveal the ethereal glow of distant celestial objects, invoking a sense of awe and wonder. Glowing nebulae around stars display magnificent structures and colours. Closer to home, within our own atmosphere, similar forms and colours are seen the dance of the aurora or northern lights. We will examine the physics behind the colour and light from distant nebulae around both young and dying stars, as well as the glorious colour of the aurorae, our nearest celestial lightshows.

Join the OSC for a family-friendly, fright-filled night of stargazing and other spooky science activities. This year is all about combining Hollywood and Halloween to highlight the love of the scary movie. Take part in the making of atmospheric special effects. Create your own scary movie scene.
