Elon Musk thinks that we can make Mars habitable by nuking it. But would that really work?

Mars might be full of salty liquid water! Plus, a guide to the upcoming Lyrids meteor shower.

Scientists have come up with some really creative ways to keep astronauts well fed in space for days and months at a time. But you should take some stories about space food with a grain of salt.

In tough economic times, our exploratory science programs -- from space probes to the LHC -- are first to suffer budget cuts. Brian Cox explains how curiosity-driven science pays for itself, powering innovation and a profound...

Around 20 years ago NASA launched a spacecraft to study the comet Wild-2. What it brought back would cause scientists to wonder whether the building blocks of life could have arrived at Earth on a comet.

If you could pilot a spaceship into Jupiter and Saturn, would you ever hit anything solid? And what's it like in there? SciShow Space takes you on a tour of the two biggest gas giants in the solar system.

Get your gasmasks ready because we're taking a trip to Titan! Reid Reimers tells us all about the mysterious moon.

Get to know Olympus Mons on Mars, the biggest volcano in the solar system, and find out why a planet that's smaller than Earth has volcanoes that are bigger than ours!

Our journey through the solar system continues, as Jessi gives you a close look at comets and asteroids!

In which John Green, Hank Green, and Emily Graslie teach you about our Sun, and the formation of the planets. We're going to focus on the formation and development of the Earth, because that's where people live. You'll learn about the...

Do you love to look at a big, beautiful full moon in the night sky? So do Jessi and Squeaks! But how did the moon get up there? And what is it made of?

The planets in our solar system have a very specific order. But have you wondered why they have the order they do?

Pluto might seem like the least likely place to find liquid water, but thanks to New Horizons, we have new information about oceans on the dwarf planet and more from the outer reaches of the solar system!

New research is changing our ideas about the history of Mars's moons and we might have found the most active region of space.

Explore the four inner rocky planets, as Jessi and Squeaks take you on a tour of the solar system!

Explore the four gas giant planets, as Jessi and Squeaks take you on a tour of our solar system!

An inside out planetary nebula has given astronomers insight into what might happen in our own solar system someday, and it's that time of year again to search for shooting stars.

Astronomers found a galaxy older than almost any we’ve ever seen before, and we have a new, faster method to use in our search for habitable planets.

Today on Crash Course Astronomy, Phil explains comets. Comets are chunks of ice and rock that orbit the Sun. When they get near the Sun the ice turns into gas, forming the long tail, and also releases dust that forms a different tail....

On January 30, 2020, we had to say goodbye to NASA’s Spitzer Space Telescope after more thank 16 years of revolutionizing infrared astronomy. Today, SciShow sends it off and says thank you by taking a look back at it’s incredible legacy.

Tag along with Jessi and Squeaks to learn how to make your very own model of the Solar System!

The fourth planet from the sun and the outermost of the terrestrial planets, Mars has long been a popular spot for missions and imagination. Phil walks you through the planet's topography, core, and features. We'll take a look back to...

NASA’s Habitable Worlds Observatory "will draw on technologies proven by the agency’s Hubble, Webb and upcoming Roman Space Telescopes," to search for life outside our solar system, according to the Goddard Space Flight Center. Credit:...

Researchers have discovered the most similar planet yet to Earth, 1,400 light-years away. Kepler-452b orbits its star in 385 days, just 20 days longer than our own year. Its star is just 4% larger, a billion and a half years older, and...
