Scientists today have revealed that there will a Terran Eclipse tonight!

This happens when the earth and the sun are so aligned that half the earth obscures the light of the sun from the other half. This rare occurrence only happens every 24 hours and plunges 50% of the earth in to darkness.

The effect is made possible because one half of the earth is exactly the same size as the other and so blocks all the sunlight that would otherwise fall on the other side.

Vast crowds of people are expected to fall unconscious as the light and heat from the sun are removed, in a state called sleep. Animals may similarly be affected and pet owners are advised to give their animals asaucer of milk as the light fades.

Scientists predict there may well be another Terran Eclipse tomorrow.

Warning: Walking around in the dark can be very dangerous: you might bump into something. The only completely safe way to observe this effect is to close the curtains, and go to sleep.
