Nice idea to include the Sun, Earth, Moon poster in The TES (July 2, 2004).nbsp;nbsp;

Slight problem though, why has the artist put a thick light halo around the Earth and a slightly thinner one round the Moon?

If this is to improve contrast with the background, I feel it is unnecessary and if it is symbolises an atmosphere it is far too thick for the Earth and not needed for the Moon! This is a shame, as it spoils an otherwise good poster and unfortunately means I will not be able to use it in my classroom.
