How to see the invisible Universe

We rely on powerful telescopes to detect the light from distant stars and galaxies. Even then, most light from objects in space is released at wavelengths our eyes can’t see, such as infrared or X-rays. Then we have black holes, dark matter, dark energy and gravitational waves, which do not produce any light at all. Learn how astronomers can ‘see the invisible’ to uncover the mysteries of the universe.
