According to a new model, days on Earth used to really fly by, and today Pluto has wind-swept dunes made of very weird sand.

Finding a red nugget galaxy is like discovering a time capsule from the early universe.

Treo creator Jeff Hawkins urges us to take a new look at the brain -- to see it not as a fast processor, but as a memory system that stores and plays back experiences to help us predict, intelligently, what will happen next.

Sometimes, in order to learn something, you've got to punch a giant asteroid.

If you think punching an asteroid to knock it off the course to Earth’s destruction is purely for science fiction, you might only be right a for a little longer! Plus, scientists are being thrown for a loop with the orbits of planets...

Rovers like Curiosity search for life on Mars using rock and soil samples, but why don't they examine liquid or frozen water?

SciShow Space takes you through perhaps the scariest part of every space mission -- re-entry. How do astronauts survive the turbulent return to Earth’s atmosphere? Math, y’all!

A paper published last week proposed a hypothesis that identified 95% of the missing stuff in the universe, but the headlines have been a little over-hyped.

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

Venus is too hot, Mars is too cold, and Earth is just right, says planetary scientist Dave Brain. But why? In this pleasantly humorous talk, Brain explores the fascinating science behind what it takes for a planet to host life -- and why...

The first time scientists found exoplanets, they were orbiting something very different from our sun: a pulsar.<br/>

The global dust storm on Mars is threatening the Opportunity rover and the wind on Venus might be changing the length of its days.

The first American astronaut to orbit Earth, John Glenn passed away yesterday in Ohio. But he leaves an admirable legacy.

Hank fills us in on the four exploratory missions to space that he is most excited about - New Horizons is going to Pluto and the Kuiper belt; Juno is on it's way to Jupiter; Dawn is exploring two large asteroids; Rosetta will land on a...

Scientists first saw patches of ice on Mercury 20 years ago, and that discovery raised a lot of questions: How could ice survive on one of the solar system’s hottest planets, and how did it get there in the first place?

There’s nothing boring about Bennu! From its chemistry, size, shape, and spin to its extremely old age, it proves that even the smallest objects in the solar system have a bizarre and fascinating history.

When astronomers study the universe, they’re often using telescopes that cost millions or even billions of dollars to build. Luckily for the rest of us, there are still plenty of incredible things to see in the sky with the more...

Tabby's star is at it again. Could it be aliens this time!? Also, astronomers have discovered a planet with the density of styrofoam!

Researchers found surprising new evidence hiding in data captured back in 1997, and we've discovered stars forming in a distant galaxy as early as 250 million years after the Big Bang.

Back in 2014, an international team of astronomers was taking pictures of distant galaxies, when they noticed a dot moving across their images. Could it be Planet Nine?

SciShow Space shares the latest news from space research, including the first definitive detection of water on an exoplanet, and a new theory for how we should search for alien civilizations.

SciShow Space brings you NEWS FROM THE FUTURE, with details about the space missions to look forward to in 2015.

Caitlin serves up the latest in space-science news, this week featuring developments in missions dedicated to sampling asteroids, detecting exomoons, and solving the mysteries of the moon.

There are some captivating things when you look up at the night sky, but our location in the Milky Way may be fogging up our view.
