What If the Dino-Killing Asteroid Hit Earth Somewhere Else

The asteroid roughly 10 km across hit Earth over 60 million years ago. One of the most devastating consequences was the mass extinction that wiped out 80% of all animal species. Its crater is now hidden below the waters of the Gulf of Mexico. But what if it landed in some other spot? Learn more about your ad choices.

A Strange Object Is Circling Earth Like a Second Moon

The closer the Moon is to the horizon, the larger it looks. This phenomenon is called the Moon illusion. And most experts believe that the illusion is created by your own mind!

In prehistoric times, the Moon was way closer to our planet than it is now. Today, we're going to share the most interesting facts about the Moon with you. It might change your mind about the Moon's simplicity. Did you know, for example, that the Moon (along with our planet) went through a Late Heavy Bombardment about 4 billion years ago? This event is also known as the lunar cataclysm. This interval lasted several hundred million years. During it, an unusually large number of asteroids collided with Earth, Mercury, Mars, and Venus...

Extreme Natural Events That Can End Earth's Lifetime

There are a few extreme natural events that could potentially end life on Earth. A massive asteroid impact, like the one that wiped out the dinosaurs, could cause catastrophic damage. Supervolcano eruptions, which are much bigger than regular volcanic eruptions, could spew enough ash and gas into the atmosphere to block out the sun and trigger a global winter. A gamma-ray burst from a nearby star could blast Earth with deadly radiation. Lastly, a significant shift in the Earth's climate, beyond anything we've seen, could make the planet uninhabitable for most life forms. Learn more about your ad choices.
