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,...

Grover Cleveland was an interesting fellow. He was a good enough Democrat to be one of only two Democrat presidents during a time of Republican domination. He was also the only president to ever get married in the White House while in...

We've learned a lot about stars! We know how they form, and we know that most of them exist in galaxies. But how are they arranged within galaxies? And are there different types of galaxies or are they all the same? There is a lot to...

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...

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...

We all know the perfect, symmetrical and flawless galaxies Hubble has set its lense on, but there is also a catalogue dedicated to the most peculiar galaxies out there... The Arp Catalogue

We all know that the universe is big. But how big it is? Much bigger than you think. Let's start out by looking at the Earth, and then zoom out to progressively larger and larger structures, so that we can see just how big it is. Then...

How the fire spread and what it looked like at its height

Este video explora el fascinante proceso de desarrollo de las plantas, desde una pequeña semilla que crece hasta convertirse en una hermosa planta, se reproduce y finalmente muere.<b<br/>r/>

Ciclos de la vida de las plantas part 2

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...

To understand where we came from—how earth, the solar system, the galaxy became what they are today—we need to understand the beginning of time. For example, how did the first galaxies pull themselves together from the dark...

How many stars are there in the universe? This question leads Hank to a couple other questions - How many stars can we see from Earth? How many stars are there in our galaxy? - but the answer to the original question proves elusive.

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....

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...

The world is full of colors. Almost all of them can be described by a wavelength of visible light, but there are some colors out there that are just in your head!

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...

As the founder of a startup, Tracy Young often worried that employees and investors valued male CEOs more -- and that being a woman compromised her position as a leader. In this brave, personal talk, she gives an honest look at the...

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,...

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...

This video is about the differences between the corpses or final degenerate dense star forms that dead stars take: black holes, neutron stars, and white dwarfs. The main distinguishing features between them are the mass cutoffs...

In which John Green, Hank Green, and Emily Graslie teach you about what happened in the Universe after the big bang. They'll teach you about cosmic background radiation, how a bunch of hydrogen and helium turned into stars, formed...

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