Carl Sagan predicted some amazing things including the aftermath of nuclear war.

Scientists have found fossils that show life appearing on Earth much earlier than we thought. Meanwhile, could there be a new fundamental force?

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.

The insides of the our gas giant friend, Saturn, might be less of a mystery now that we’ve figured out how to use its rings to indicate its internal makeup. And the light emitted from some very old, very hungry black holes could be...

Good news for fans of Venus - last week, NASA announced two new missions to learn more about our planetary neighbor! And this week, NASA's Juno mission sent back a treasure trove of data about Ganymede - the largest moon in our solar...

Scientists have conclusively imaged a circumplanetary disk around a distant exoplanet, and Jupiter's auroras claim the spotlight with their unique Birkeland currents.

After observing what we thought was just a big asteroid in the asteroid belt, a team of astronomers now thinks this might qualify as a dwarf planet. And scientists had the chance to directly observe the collision of two neutron stars for...

Earlier this spring NASA announced a new research model that predicts that ocean worlds are far from rare, and our galaxy might be full of them. And a new study examines evidence that Pluto may have had an underground ocean all along!

If water just keeps getting recycled by a closed system on Earth, how did it get here in the first place? Where did the cycle begin?

There's a lot more to Saturn's rings than just looking awesome! Find out why!

Last time, we learned that there is in fact weather on other planets. But those were the rocky planets, like Earth. What about the big Gas Giants? What's the weather like there? In this episode of Crash Course Kids, Sabrina takes us on a...

Some of the biggest evolution questions finally answered.

New simulations of a triple-star system in the constellation Orion suggest that a planet might be orbiting three stars, which could drastically increase the amount of the solar systems we believe are out there forming planets! And the...

Our planet shares a lot with other rocky planets in our solar system, but astronomers have found a few mountains out there that are nothing like ours.

SciShow Space shares the latest news from around the universe, including the first observation of a star-within-a-star, and the debut image from the newest telescope to be enlisted in the hunt for alien worlds.

Have you ever wondered if aliens exist? You're not alone! Learn about what alien life needs to survive in the universe!

There are exoplanets out there that seem very Earth-like, but if you look out and see liquid metal instead of liquid water, you might be in the Venus zone.

You know nothing.

Hank's news this week informs us on a couple of crazy science experiments, updates us on some earlier topics (dangerous asteroids and ancient phallic rock art), and briefs us on a new study that seeks to find the evolutionary origins of...

The creation of tiny robots could enable the exploration of new frontiers, from the tightest spaces in the human body to the most remote ecosystems. Here are 5 little bots that draw inspiration from nature to get the job done.

Scientists have found at least three cycles in nature that can be traced back to the alignment of the planets. And while they won’t tell you anything about your love life or personality, by studying them, we can learn about our planet’s...

Astronomer Jean-Luc Margot has come up with a new definition for planets that may help us categorize worlds outside of the solar system, and we may have also discovered a new dwarf planet within the solar system!

While we like to imagine little green men, it's far more likely that life on other planets will be microbial. Planetary scientist Nathalie Cabrol takes us inside the search for microbes on Mars, a hunt which counterintuitively leads us...

We tend to think of fossils as dinosaur bones or petrified wood, but what if we told you that there's a lot we can learn from fossilized waste?
