Understand the night sky
All guidesShort guides to finding planets, reading the Moon, watching meteors and eclipses safely.
- How to find planets in the night skyFive planets are easy to see with the naked eye. Here is where to look, when, and how to recognise them.
- Moon phases explainedThe Moon is always half lit by the Sun. What changes is how much of that lit half we see from Earth.
- How to watch a meteor showerNo equipment needed: a dark sky, patience and the right hours after midnight.
- How to learn the constellationsStart with one bright pattern you cannot miss, use it as a signpost to its neighbours, and come back a month later: the sky will have turned, and you will know a little more of it.
- Binoculars for stargazing: what to buy and what to look atA pair of 7x50 or 10x50 binoculars shows the craters of the Moon, the moons of Jupiter, dozens of star clusters and the Andromeda Galaxy, for a fraction of the cost of a telescope.
- How to watch a solar eclipse safelyNever look at the Sun without a proper solar filter, except during totality. Here is how to watch safely.
