We've talked at great length about the beginning of the universe, everything we know, and what we don't yet know. But everything that has a beginning must have an end. How will the universe end? How can we tell? When will it happen?...

A study of 544 star-forming galaxies observed by the Keck and Hubble telescopes shows that disk galaxies like our own Milky Way unexpectedly reached their current state long after much of the universe's star formation had ceased. Over...

The Hubble Space Telescope is keeping watch over many, many galaxies using the combined superpowers of its incredible optics and a quirk of nature called gravitational lensing.

Take a space walk through the Milky Way galaxy, our home in the vast universe. Exploring the origins of its name and the concept of galaxies, the video delves into the size, shape, and composition of the Milky Way. It also highlights the...

We can't use tape measures, rulers or lasers to measure the astronomical distances to stars and galaxies, so how do we do it?

This live-action video program is about the word universe. The program is designed to reinforce and support a student's comprehension and retention of the word universe through use of video footage, photographs, diagrams and colorful,...

The world is said to be a big place, but the universe is much bigger and what’s more, it’s expanding all the time. How do we know this? Because of the evidence provided by red shift.

The James Webb Space Telescope will explore every phase of cosmic history: from the formation of the very first galaxies in the early universe, to our cosmic backyard of the Solar System. Webb is the largest space telescope NASA has ever...

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...

What is the purpose of the VLA? What astronomical objects do they observe? Why was the VLA renamed Carl G. Jansky Very Large Array? What are the characteristics of the antenna?<br/>
The Very Large Array Telescope, Part 1

The $10 billion James Webb Space Telescope has safely arrived at Lagrange Point 2 — and it’s now getting ready to look back in time to 13.7 billion years ago.

This live-action video program is about the word black hole. The program is designed to reinforce and support a student's comprehension and retention of the word black hole through use of video footage, photographs, diagrams and...

At the beginning of this series, we talked about the Big Bang, which was the beginning of our universe, and what happened in the early epochs thereafter. But what we didn't talk about was how we know all that stuff! What is the evidence...

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...

For a while now, we've been discussing all of things we know about the universe. What about some of the things we don't know? If we look to the current frontier of astronomy, we find two mystifying concepts, dark matter and dark energy....

Now that we've learned about the first ten billion years in the development of the universe, it's time to get a little more specific to our own species. We live in a galaxy called The Milky Way. When did it form, and how? Where is it...

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,...

Do you want to learn about space stuff? Do you want understand stars and galaxies, black holes and quasars, dark matter and all the rest? This is the playlist for you! We will start at the beginning of the universe, and get all the way...
