It's a big day for Jessi and Squeaks because they've finally finished their brand new observatory! Join them as they try out their new telescope and take a look back at a compilation of everything we've learned about space so far!

The universe is a big place full of galaxies that we've only begun to study. SciShow Space presents 3 of the strangest ones we've found so far.

Thanks to the Space Telescope Science Institute (STScI) and NASA's James Webb Space Telescope for supporting this video! In particular, thanks to Dan Coe of STScI for taking the time to chat with me about what we do and don't know about...

When we look at the sky, we have a flat, two-dimensional view. So how do astronomers figure the distances of stars and galaxies from Earth? Yuan-Sen Ting shows us how trigonometric parallaxes, standard candles and more help us determine...

The spiral of the Milky Way is not as smooth as we once thought because an arm not so far from home appears to be broken! And we may have discovered the answer to why a local asteroid puts on the appearance of a comet.

Before you take your relationship with space to a new level by getting a telescope, find out what you really need to make the most of your summer nights staring at the sky.

Lots of people believe the Universe is infinite, but there's a good possibility that might not be the case. Which means that there would be an actual edge of the Universe. What happens at that edge? Is there a restaurant?

Is the universe expanding? About a hundred years ago astronomers made a discovery that helped us unravel the mystery of the history of the universe!

Population III stars were the very first stars in our universe and far larger than any we can see today. Where are they now?

Ever wanted to explore the Cosmic Background Radiation? It's our best picture of the big bang, and now you can!

Paul Andersen describes our place on the Earth in the Solar System within the Milky Way Galaxy in the Universe. The make-up and origins of the Universe are included along with stellar evolution. A teaching progression K-12 is also...

Thanks to observations of galaxy redshifts, we can tell that the universe is EXPANDING! Knowing that the universe is expanding and how quickly its expanding also allows us to run the clock backwards 14 billion years to the way the...

In which John Green, Hank Green, and Emily Graslie teach you about, well, everything. Big History is the history of everything. We're going to start with the Big Bang, take you right through all of history (recorded and otherwise), and...

Active galaxies pour out lots of energy, due to their central supermassive black holes gobbling down matter. Galaxies tend not to be loners, but instead exist in smaller groups and larger clusters. Our Milky Way is part of the Local...

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular....

Welcome to the first episode of Crash Course Astronomy. Your host for this intergalactic adventure is the Bad Astronomer himself, Phil Plait. We begin with answering a question: "What is astronomy?"

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

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.

Discover "Stars and Galaxies" with our catchy video that makes learning about the universe exciting and fun! Perfect for kids, this tune will spark your imagination and teach you fascinating facts about the vast cosmos and its celestial...

Explore "How Are Black Holes Formed?" with our catchy video that makes learning about space fascinating and fun! Perfect for kids, this tune will spark your imagination and teach you the science behind the formation of these cosmic wonders.

Scientists have made a groundbreaking discovery in a galaxy 12 billion light-years away: complex organic molecules, the basic building blocks of life. This finding, glimpsing into the universe's infancy, suggests that the fundamental...

James Webb captures infrared light, which allows us to see billions of light years away. Some galaxies would not be visible otherwise, because their light has redshifted beyond visible light spectrum due to the...

Science Kids Famous Astronomers and Astrophysicists - From Galileo to Neil deGrasse Tyson

Vera Rubin was a pioneering astronomer who defied gender discrimination to make groundbreaking discoveries in the field of astrophysics. Her...
