SciShow Space takes you inside solar flares, and how we've managed to get the best look at one yet, along with news about a new, Web-based simulation of the earliest days of the universe that you can explore yourself!

What happens when matter can't get any denser yet somehow does? The answer - it becomes strange. Strange Stars may be the most massive stellar remnant that is just shy of forming a black hole. And they could be even cooler than black holes.

Hank gives us an inclusive overview of how everything in the universe is thought to have begun, and how cosmologists predict it will all come to an end. Now get happy!

Roughly 85 percent of mass in the universe is "dark matter" -- mysterious material that can't be directly observed but has an immense influence on the cosmos. What exactly is this strange stuff, and what does it have to do with our...

SciShow Space News revisits one of the biggest (potential) astronomical discoveries of 2014, one that promised to revolutionize our understanding of the formation of the universe. Turns out, we're not quite there yet.

We think of space as a silent place. But physicist Janna Levin says the universe has a soundtrack -- a sonic composition that records some of the most dramatic events in outer space. (Black holes, for instance, bang on spacetime like a...

Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with a Big Bang, when...

Scientists are still working on theories that might help explain what the vast majority of our universe is made of.

Physicist Patricia Burchat sheds light on two basic ingredients of our universe: dark matter and dark energy. Comprising 96% of the universe between them, they can't be directly measured, but their influence is immense.

The universe is expanding. But how much is it expanding? Is it doing expanding the same way everywhere? And can physics actually explain the expansion?

Astronomers are learning just how big early stars might have been, and how their deaths have shaped the universe. Some may have even been so massive that they skipped the whole star phase and collapsed straight into black holes!

More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. "All that energy was pumped into the fabric of time and space itself," says theoretical...

There are a few ideas about how the universe will end, but a paper published last week suggests that dark energy might eventually rip everything apart!

When and how did the universe begin? A global group of astronomers wants to answer that question by peering as far back in time as a large new telescope will let us see. Wendy Freedman headed the creation of the Giant Magellan Telescope,...

"Rock-star physicist" Brian Cox talks about his work on the Large Hadron Collider at CERN. Discussing the biggest of big science in an engaging, accessible way, Cox brings us along on a tour of the massive project.

On March 17, 2014, a group of physicists announced a thrilling discovery: the “smoking gun” data for the idea of an inflationary universe, a clue to the Big Bang. For non-physicists, what does it mean? TED asked Allan Adams to briefly...

Models of the universe’s early days have only been possible with dark matter as a variable, but we still don’t have proof that dark matter exists. But recently, scientists may have found a way to replicate the results without the...

At Serious Play 2008, Charles Elachi shares stories from NASA's legendary Jet Propulsion Lab -- including tales and video from the Mars Rover project.

Now that gravitational waves are definitely a thing, it's time to think about some of the crazy things we can figure out with them. In some cases we're going to need a gravitational wave observatory - in fact, we've already built one.

Almost all matter in the universe should have been annihilated shortly after the Big Bang, but looking around, we see galaxies, stars, planets, and, you know... us. So obviously that didn't happen, and the why of it may have something to...

Our fundamental picture of the universe seems pretty nearly complete these days, to the point that some people are suggesting that we’ve arrived at some version of “the end of physics.” And sure, physics is at a turning point, but it...

In this wide-ranging, thought-provoking talk, Kevin Kelly muses on what technology means in our lives -- from its impact at the personal level to its place in the cosmos.

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.

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!
