We here at SciShow like to start things off with a "Boom" for yet another season! Hank talks about the mystery behind the "Space Roar" and why it is we can't really hear it.

What can an equation tell us about whether or not we're alone in the universe?

Why You Should Care About Nukes

It's leap year time... so what are years, anyway? And what do they have to do with the supermassive black hole in the core of the milky way?

For ages I’ve been thinking about doing a video analyzing time travel in fiction and doing a comparison of different fictional time travels – some do use wormholes, some relativistic/faster than light travel with time dilation, some...

Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been...

Albert Einstein strongly disagreed with Niels Bohr when it came to Bohr's interpretation of quantum mechanics. Quantum entanglement settled the argument once and for all.

Jedidah Isler first fell in love with the night sky as a little girl. Now she's an astrophysicist who studies supermassive hyperactive black holes. In a charming talk, she takes us trillions of kilometers from Earth to introduce us to...

Tiny remnants of extreme nuclear reactions in space are flying through your body right now. And astronomers are hunting them to learn more about some of the most energetic and violent objects in the universe.

Nothing's final yet, but there might be a drone, called the Mars Helicopter, on the upcoming Mars 2020 rover.

This week on SciShow Space News, researchers have figured out which gas drives fire fountain eruptions on the Moon. And you can send a message or your name to the Moon or Mars!

Astronauts ate some space-grown lettuce, and astronomers discovered a ring of galaxies that's so big it defies the laws of physics.

SciShow News serves up the latest pictures from Comet 67-P, that media darling, and the discovery of what may be the oldest, rocky Earth-like worlds yet found.

Michael Collins isn't as recognizable a name as Buzz Aldrin and Neil Armstrong, but his job on the Apollo 11 mission was just as important.

SciShow Space preps you for the Delta Aquarids, a meteor shower, and explains what makes them so unique. Plus, join "aquanauts" on one of NASA's least-known missions, a nine-day tour in its NEEMO undersea laboratory.

This week in space. Scientists have discovered a black hole that could possibly everything we know about black holes, and also, evidence that planets, yes planets, could form around super massive black holes.

Two scientists have proposed that Planet Nine could actually be a black hole, and a handful of telescopes observed a distant black hole absolutely destroying a star!

Exorings are pretty elusive, but we’ve already found what might be the first set of exorings, and if we find more, we’ll have a treasure trove of new information.

Earth probably isn’t the best place in the universe. It turns out there might be even better places to live that are even more suitable for life: superhabitable planets.

October was bittersweet for space scientists as we said goodbye to both the Kepler Space Telescope and Dawn mission.

It's not the happiest subject, but when someone dies in space, or on another planet, what will happen to the body?

Carbon dioxide is the biggest player in the climate crisis, reshaping our world in an urgent way, but that’s not the only way CO2 has changed the world. It’s also contributed to making some of the weirdest places on Earth.

Modern work -- from waiting tables to crunching numbers to designing products -- is about solving brand-new problems every day, flexibly and collaboratively. But as Yves Morieux shows in this insightful talk, too often, an overload of...

How likely is it that a massive asteroid will do major damage to Earth and its inhabitants? What about the sun -- is it dying out anytime soon? And the supermassive black hole at the center of the Milky Way -- should we be worried about...
