How many stars are there in the universe? Are there more stars out there than grains of sand on Earth? Thanks to advanced space telescopes, we've been able to peer farther into deep time and the distant universe than we ever thought...

Planetary scientist Carolyn Porco shows images from the Cassini voyage to Saturn, focusing on its largest moon, Titan, and on frozen Enceladus, which seems to shoot jets of ice.

Join us for a trip into the SciShow Space News Debunker, where we explore the rumors that NASA has created a warp drive.

We explore several exoplanets whose features make us think they shouldn't even have been able to form in the first place!

Massive stars die in fantastic explosions called supernovas. Most of them fit neatly into a few categories, but then there are the peculiars, a special group of supernovas that don’t quite fit in with the rest.

2020 wasn't ALL bad news. This year scientists found ludicrously fast stars, ancient galaxy clusters, and developed a camera that could change how we study the night sky.

Hank discusses the launch of an all new channel: SciShow Space! This new channel will be all space. All the time.

The ubiquitous yin-yang symbol holds its roots in Taoism/Daoism, a Chinese religion and philosophy. The yin, the dark swirl, is associated with shadows, femininity, and the trough of a wave; the yang, the light swirl, represents...

Luke Syson was a curator of Renaissance art, of transcendent paintings of saints and solemn Italian ladies -- Very Serious Art. And then he changed jobs, and inherited the Met's collection of ceramics -- pretty, frilly, "useless"...

Samples from the Curiosity rover suggest that Mars had a potentially habitable lake in its past, and gravitational lensing has helped scientists weigh a star!

It turns out if you’d like to take a deeper look into the universe, the universe itself might actually help you do that!

Killing all the life on Earth is easy. But what about destroying the planet itself? That is DEFINITELY going to happen!! But HOW? Could it be Nukes? A Giant Asteroid? A Collision with another planet? And what's more, will anyone be...

Carl Sagan famously observed that we are all made of "star stuff." But what does that mean? And how much of you is really made of dead stars? SciShow Space explains!

Where Was The Big Bang

It has NO EDGE. And NO CENTER... or does it?

Speaking as both an astronomer and "a concerned member of the human race," Sir Martin Rees examines our planet and its future from a cosmic perspective. He urges action to prevent dark consequences from our scientific and technological...

X Prize founder Peter Diamandis talks about how he helped Stephen Hawking fulfill his dream of going to space -- by flying together into the upper atmosphere and experiencing weightlessness at zero g.

Science fiction writer Monica Byrne imagines rich worlds populated with characters who defy our racial, social and gender stereotypes. In this performance, Byrne appears as a hologram named Pilar, transmitting a story of love and loss...

Something massive, with roughly 1,000 times the area of earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing...

Hank explains how quasars and blazars are both the same thing - just oriented differently in respect to us - and how that impacts the way we perceive them and how it also effects the ways we can study them.

We’ve done a lot of searching for life in the universe and we need to continue to if we hope to make contact. But not all of our attempts were expected to succeed. That’s where Beacon in the Galaxy comes in.

An incredibly bright burst of energy and a dent covered with ice give us insights into planetary and universal structure.

Humans have been studying the stars for thousands of years, but astrophysicist Juna Kollmeier is on a special mission: creating the most detailed 3-D maps of the universe ever made. Journey across the cosmos as she shares her team's work...
