What would happen if the Earth had to endure a catastrophe such as an asteroid strike or a gamma ray burst?  How would that affect life here?  Find out about the lurking dangers and what we could do about them.  Discover the wake-up call that could have destroyed our blue marble.  However, it made us aware of how vulnerable we are.


Comet Shoemaker–Levy 9 impacted Jupiter on July, 1994.  This comet was previously designated D/1993 F2 and was anticipated to come close to Jupiter.  The comet consquently broke apart before it struck Jupiter. No one, including its discoverer, could have imagined how intense and dynamic the impact would have been.
