ONE of my favourite stargazing memories is the first time I viewed the rings of Saturn through a telescope. The planet, with its iconic shape, came into focus before my eyes, and I was looking at it in real time.

In reality, what I was seeing was just over an hour in the past, as light from Saturn takes over an hour to reach us on Earth.

This was a few years ago, but even to this day I feel a sense of awe when looking at the gas giants Jupiter and Saturn through binoculars or a telescope.
