Will life on Mars go the way of the dinosaurs before we have a chance to discover it? Incoming Comet C213/A1, discovered on January 1st, is expected by some astronomers to pass within 28,000 miles of Marsin 2014. But cometary trajectories change, and an impact is not impossible, although NASA estimates that the object will pass Mars at a distance more like 80,000 miles.

Should it hit the planet, it will cause a spectacular explosion, releasing the equivalent energy of billion megatons of TNT. This is roughly the size of the blast that climaxed the extinction of the dinosaurs 65 million years ago.

Ever since the publication of the groundbreaking book the Cycle of Cosmic Catastrophes in 2006, a controversy has raged about whether or not the explosion of a comet over southern Canada almost 13,000 years ago might have led to the catastrophic collapse of the great ice sheets and the floods that followed, that are memorialized in myths and legends around the world.

Now a new study offers further evidence that this is exactly what happened. Could it happen again?

The are a lot of strange sounds around lately (NOTE: subscribers can still listen to these special reports). Two unusually powerful explosions occurred in Siberia on February 9th and 12th–were they caused by the same thing as the Tunguska explosion of 1908? The explosions were so huge that the residents of nearby cities felt powerful tremors and many of them ran out into the street in a panic.read more

When our satellites search for other planets that might harbor life, they always search for water. But now, for the first time, astronomers have detected around a burgeoning solar system a sprawling cloud of water vapor that’s cold enough to form comets, which could eventually deliver oceans to dry planets. And with oceans, life could spring up–or maybe migrate to the planet from another place.
