While astronomers are busy searching for life beyond Earth, they’ve also started asking another question: If life seems so difficult to find, then why is our world so full of it? One answer might be overhead right now: the Moon!

You might think of plate tectonics as destructive since it's the ultimate force behind earthquakes, tsunamis, and volcanic eruptions. But the slow movement of our planet's surface does a lot more than shake things up now and then. Some...

There is some super weird, noodley stuff inside neutron stars and scientists have found evidence that black holes can have strange geometries.

The earth is our home, and while we like to think we know a good deal about it, there are still some mysteries that scientists are looking to unravel.

Deep below the surface, the ocean floor is full of riches. There’s gold, iron, and lots of other rare, precious metals. What kind of geochemical processes can leave loot all over the seafloor?

You need it, you love it, you probably live on it: it's land! But have you ever thought about where land even comes from?

In the aftermath of a 8 – 20 solar mass star’s demise we find a weird little object known as a neutron star. Neutrons stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars,...

You may have read that 2018 is looking to be a bad year for earthquakes, but Hank is here to offer you some assurances.

We’ve detected seismic activity all around the solar system, from earthquakes to moonquakes, marsquakes to venusquakes. But the most dramatic quakes we know of actually happen on stars!

It’s not easy to find active plate tectonics on other worlds, but doing so may bring us one step closer to finding a planet that can support life.

Happy Pi Day! We are huge fans of homophones here at SciShow, so we put together a whole bunch of fun facts and tasty tips about PIES! Get it?!

Devastating earthquakes happen every year, and it's difficult to predict when they will happen. But they do follow one mathematical pattern known as the Devil's staircase.

We’ve done a surprising amount of exploration on Mars, from its atmosphere, to its surface, and miles deep into its canyons. But mapping its insides has been a quandary that we hadn’t been able to solve until last week!

We’ve been sitting on samples of the lunar surface for decades and, with better technology than when they were taken, we are opening them back up to take another look!

New research suggests that Venus’ patterned crust might currently be more active than we thought! Astrophysicists have also modeled the orbits of mysterious objects between Jupiter and Neptune, and found that they could have come from...

Earth’s outer shell is made of two materials whose different densities and thicknesses give rise to two distinct “levels” on the planet’s surface.

Astronomers have some insights into the mysterious disappearance of the luminous blue variable star in the Kinman Dwarf Galaxy, and we're digging up more clues about how our friend the Moon may have formed.

Mars Express, one of the longest-running planetary probes ever made, was only intended to last for about two Earth years, but it's still going at 17! And it's taught us an unbelievable amount, including everything from studying its...

The story of Atlantis, a mythological continent that vanished into the sea after its inhabitants displeased the gods, has fascinated people for thousands of years. However, the idea of a whole continent sinking into the ocean may be more...

Why is All Sand the Same?

Earth's thick crust might one of the reasons our planet can support life. But scientists are looking for something a little more brittle.

Your favorite TV chef might have told you to make sure you sear your meat because that nice brown crust helps seal in the moisture, but is that actually how it works? Michael explains the science of your cook out.

With acidic puddles, lava lakes, and one of the most important early hominid discoveries, the Danakil Depression is home to all of the extremes.

In about 200 million years, Earth is due for another supercontinent. What exactly that supercontinent will look like, though, depends on a lot of geological factors, and is harder to guess at than you might think! Today, SciShow walks...
