The night sky is filled with stars but visible light is only a tiny fraction of the information that reaches us from space. Modern astronomers study the invisible Universe using the whole electromagnetic spectrum from gamma rays at one end to radio waves at the other. Shooting stars mark space dust burning up in the atmosphere but larger chunks reach the Earth as meteorites. There are even sub-atomic particles, some known as cosmic rays, that crash into the atmosphere moving at near the speed of light. And in recent years we have detected gravitational waves, ripples in space-time produced by distant cataclysmic events. Join our panel of space scientists to discuss how we can now take advantage of all these different messengers from deep space to learn more about the cosmos.
Panellists: Ben Stappers, Sarah Crowther, Justin Bray and Tana Joseph
