Now don't panic. Somewhere, deep in the galaxy, a huge demolition ball of gas and dust is racing straight towards us. It's so dark you can't see it, but it's there all the same. What's worse: when it visits our solar system, it will create havoc and destruction on Earth.
`Nemesis', is the ominous name scientists came up with when they began speculating about the sinister space body in 1984. They couldn't have picked a better name: if Nemesis really exists, it should be one of the worst enemies of life on earth. Our solar system is what Nemesis calls `home'. And the bad part is: home is where Nemesis is heading.
