Astronomy Videos Index

Here is the full DeepAstronomy.com astronomy videos index. This is the only place where you can download all videos in full HD quality as well as watch them with no ads. These are the same astronomy videos made on my YouTube channel: DeepAstronomy YouTube Channel

In addition to the YouTube Channel, there is also a DeepAstronomy Podcast that you can subscribe to here


The Hypernova of VY Canis Majoris

VY Canis Majoris is one of only about 10 stars like it in the Milky Way. It is over 3,600 times the size of our Sun and is consuming its nuclear fuel at an astonishing rate. It releases more energy in six seconds than our Sun does in an entire years. And it is getting ready to die.


How Do We Know Black Holes Exist?

It's a natural question to ask how we know black holes exist if we can't see them. This video step through the history of thinking on the idea of black holes and our first actual observations of one.


How the Hubble Space Telescope Will Die

If we do nothing, in 2024 the Hubble Space Telescope will die. Here's how it will happen.


How the Universe Was Formed

This video is one of my favorites. It is a very short video describing how the large scale structure of the universe came about.


Exoplanets: The First Earth-Sized World of Kepler

We have found 500 planets in orbit around other stars. Most of these exoplanets are very large gas-giants, many much larger than Jupiter and are detected by measuring small dips in brightness as the planet moves across the disk of the host star.


The Hubble Ultra Deep Field in 3d

In 2004, the scientists working with the Hubble Space Telescope pointed it at an obscure area of the sky, and found something extraordinary.


The Apophis Asteroid: What You Need To Know

Here is an introduction into the asteroid Apophis, including what we currently know about the 2029 and 2036 flybys and a little history.


Behind the Mysterious Fog Surrounding the Milky Way

The center of our galaxy, the Milky Way, is home to a supermassive black hole surrounded by clusters of young stars and giant molecular clouds. A group of scientists at NASA's Fermi Gamma-Ray Space Telescope announced the discovery of two bubbles of energy erupting from the center of our galaxy.


What is the Universe Expanding Into?

Since we know the universe is expanding and accelerating as it does so, it makes perfect sense to ask the question, What is it expanding into? In this video, I try to offer an explanation.


Where Are the First Stars and Galaxies?

We have data from when the universe was only 400,000 years old. We also have images from the Hubble Space Telescope showing us the earliest galaxies - a time when the universe was 460 million years old. And we have almost no data in between. Where are the first stars and galaxies?


What Would It Be Like To Travel Into A Black Hole?

Is travel into black holes possible? What would such a journey look like? This video gives us some idea of what a journey into a black hole would be like and what strange physics are in play in this realm of very strong gravity.


The James Webb Space Telescope: The Largest Telescope Ever Built

It will be the largest telescope to ever fly in space. It is so large that it must be carefully folded to fit into the rocket that will launch it and then unfolded when deployed.


Olbers Paradox: Why is the Sky Dark At Night?

If you add up all the photons spewing out of all the stars and galaxies and the space in between, there is enough to light up the universe, yet when we look up at the night sky, this is clearly not the case. So, why is the sky dark at night?


The Decay of Heaven

If we accept the implications of the current observations of universal expansion, then the future of the universe is rather bleak. The inexorable tide of inflation will ultimately land the cosmos on the shores of desolation and heat death.


What Caused the Big Bang?

For almost one hundred years, we have known that the universe is expanding. We have traced this expansion back in time, through to the very beginning when the universe occupied an infinitesimal point in space. This was the state of the universe at time t=0, over 13 billion years ago.

I started a blog!

There's a lot of information I like to get out to people that don't warrant an entire article.

I've been posting things like astronomy news and answers to questions I get from people who watch my astronomy videos or read this website. Think of it as a supplement to your love of astronomy!
