Our solid core has given us life as we know it. But what if Earth was hollow?
The sound of trickling water might seem harmless, even peaceful. But in the polar regions, this sound is a sinister warning of an event that could swallow up the arctic...
Scientists have discovered many planets similar to Earth beyond our solar system. These exoplanets can be up to 10 times larger than Earth, which might be ideal for our...
It’s almost as old as the Universe, and as massive as 34 billion Suns. It eats stars for breakfast. And now it’s about to consume our own. Behold, the great...
The Earth might not be here forever. A huge solar flare, an asteroid impact, or a local gamma-ray burst – anything could wipe us out for good. If we’re...
It may sound like a myth ripped from ancient legends, but there is a real place on Earth where animals appear to turn to stone. Welcome to Lake Natron, a deadly lake in...
A massive asteroid just hit Earth, right in the middle of the Atlantic Ocean. Thanks to NASA’s new infrared telescope, we were able to detect it and prepare for the...
Imagine Earth covered in thick sheets of ice. And sea levels so low you could walk to a different continent. This is what our planet would look like during an ice age...
What if we took everything that sustains life on this planet, and shrunk it down to one small bubble? Earth’s biosphere stretches about 20 km (12 mi). From the...
But how would a second moon affect the ocean tides? Would months on Earth become longer or shorter? And would these two satellites inevitably collide to cause a...
As thrill-seekers, we like to do a lot of extreme, gravity-defying stunts to push our limits. If base jumping or caving is your thing, how about taking a tumble all the...
The Solar System may appear calm and well organized, but it is actually the result of billions of years of delicate cosmic balancing. Changing the order of the planets...
Imagine landing on a planet where the surface looks frozen but burns hotter than your oven. Welcome to Gliese 436b, one of the strangest known planets in the universe...
[dx_custom_adunit mobile_id=”RTK_v1lP”] If laws didn’t govern our world, would you still know the difference between right and wrong? If you...
Some of the planets in our Solar System are gigantic. But what if they got even bigger? Let’s go up the planetary size chart and see what kind of chaos doubling the size...
Coastal cities across the globe are planning how they will keep the sea away as it rises. One solution? Just move the city. How much would it cost? How do you lift a...
Right now, there are 1,500 active volcanoes on Earth. Just one of those volcanoes could do catastrophic damage. But at midnight tonight, every volcano on the planet is...
In a galaxy far away, gravity didn’t quite work the way it does on Earth. And the speed at which everything moved was really weird too. Maybe, some places in our...
Imagine looking up into the night sky and seeing not one but 79 different moons beaming back at you. What would this new night sky look like? How would this affect the...
Space is full of treasures. Literally. If we were able to extract the resources from the rocks in the asteroid belt alone, we could give $100 billion to every...
