You're probably used to real galaxies having curves, except not all of them seem to have gotten the memo.

This show explores the fascinating features of the universe, the different types of galaxies in our solar system and the position of our solar system in the Milky Way Galaxy. Other terminology includes: constellations, spiral galaxy,...

The video is a lecture presentation on the topic of the expanding universe. The speaker discusses evidence and the Big Bang theory, which suggests that the universe began from a small, dense region and has been expanding for...

So we've made it all the way to the 20th century with the history of astronomy. Plenty had to happen to get us to that point, but the most amazing stuff is yet to come! Shortly after Einstein did his best work, a guy named Edwin Hubble...

Edward Jenner describes the experiment he carried out to develop his vaccination against smallpox 

Black holes are really only dangerous if you get too close. Ha, who am I kidding. It turns out they may be responsible for ending star formation across the entire universe.

When we first realized that black holes could have...

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...

Today, thanks to better early detection, there are 63% fewer deaths from heart disease than there were just a few decades ago. Thomas Insel, the director of the National Institute of Mental Health, wonders: Could we do the same for...

We've been trying to count the galaxies in the universe since the mid '90s, but our estimates change as our tools improve. So what does our current estimate really mean?

With so many galaxies in the universe, some are bound to astound us. Here are three of the most extreme galaxies scientists have discovered so far.

Quantum mechanics is our best theory of the fundamental nature of reality, but it's usually only distinguishable from familiar classical mechanics on the smallest scales. But it’s also possible that our entire galaxy is filled with a...

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....

The Milky Way is often described as measuring 100,000 light years across and containing the mass of a trillion Suns. But our home galaxy is actually far bigger, and might be much less massive. Astronomers aren't sure what the exact stats...

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 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...

Our universe started with the Big Bang, but how will it end? Explore cosmologists’ three possible scenarios: the Big Crunch, the Big Freeze and the Big Rip. -- We know about our universe’s past: the Big Bang theory predicts that all...

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.

Scientists have spotted a galaxy from the early origins of the universe, and found evidence to support the existence of a 9th planet in our solar system.

In the aftermath of a 8 – 20 solar mass star’s demise we find a weird little object known as a neutron star. Neutrons stars are incredibly dense, spin rapidly, and have very strong magnetic fields. Some of them we see as pulsars,...

In 2023, a team of researchers proposed that our universe experienced not one, but TWO Big Bangs about a month apart from one another. The first for the stuff described by our Standard Model of Particle Physics. And the second for that...

More than half of all the matter in the universe is out in the dark, 'empty space.' Although it's basically invisible, the intergalactic medium has a lot to tell us about the stuff we can see.
