Spark and Perl go looking
We are going round the wrong way.
We are going the way this moon goes.
And you are quite right.
It is the wrong way.
Moons cannot do that!
Only if they did not form together with the planet.
This one was wandering past and Neptune grabbed it.
Is that pink snow?
Frozen air.
Most of our air is nitrogen. Here the nitrogen falls as snow.
You could not breathe it. There is no oxygen here.
Cold enough to make your teeth ache from the inside.
What is on the other side?
Nobody knows. One spacecraft went past, once, and only ever saw half of it.
No — it is too faint, and Neptune outshines it.
From nowhere on Earth.
Where the Earth is clear, it climbs high in the sky. The darker it gets, the lower it stays. Where it is black, it never comes up. No shading at all: it does not matter where you live.
Could you stand on a planet or moon?Which one does not belong?
