Your Fridge Isn’t Green, but It Could Be
Refrigeration and air conditioning are among the largest sources of carbon, and the refrigerants we use are greenhouse gases, too. But green refrigerants are on the way, from elastocaloric cooling to a method a bit like salting an icy road.

Why Are Craters Always Round?
If you take a look at all the impact craters in our solar system, the vast majority are nice, neat circles. But why? Meteorites and asteroids strike planets and moons at all sorts of angles. Where are all the elliptical craters?

Why Aliens Might Love Their Frozen Home
In the hunt for life beyond Earth, scientists shouldn't skip over frozen planets. In some cases, ice might actually help life evolve!

Most Planets Don't Orbit Stars!?
Hunting for rogue planets is like hunting for an invisible needle in a haystack. But we're getting a much clearer view thanks to gravitational microlensing surveys. And it looks like there are a LOT more of them out there than we thought.

Why Are Saturn’s Rings Younger Than Saturn?
Saturn's rings are younger than Saturn, and the most spectacular sight in the Solar System is also disappearing. How do we know? By running our finger through some cosmic dust.

There's Water on...the Sun?
With an effective surface temperature of roughly 5,500 degrees Celsius, you might think water couldn't survive on the Sun. Well, scientists debated whether or not it was there for nearly a century, and it turns out, it can!

The Earth's "Boring Billion" Years Were Anything But
About 1.8–0.8 billion ago, the Earth went through a period known as the Boring Billion, where not a lot changed in terms of geology, evolution, or even the number of hours in a day. Some scientists call it “the dullest period in Earth’s...

We’re Wrong About How Mountains Form
We think we know how mountains form. Plate tectonics causes rock to be pushed up at fault boundaries. Except that model is hard to prove, and a new study suggests it might actually be a lot more complicated.

Our Solar System Might Have TWO Hidden Planets
After Pluto's demotion to dwarf planet in 2006, our solar system went from having nine planets to eight. But about a decade later, some astronomers proposed there was another planet, larger than Earth, hiding in the Kuiper Belt. And in...

When Tree Planting Goes Wrong
Trees are a super-efficient way to sequester carbon, but since planting the wrong trees in the wrong place can do more harm than good, we need to go about tree planting more carefully.

Whale Poop Helps Cool Our Planet
You might not think of a sea creature as helpful in the prevention of climate change, but sperm whales have been doing their part to cool the planet by doing what most animals do best: pooping.

This Diagram of Earth Is a Lie
When you learned about the Earth’s interior in school, you were probably shown a diagram that looked like a perfect layer cake. But we've known for a long time that that diagram is... inaccurate at best, and leaves out information that...
