DOCUMENTARIES

Into the Unknown tells the story of the building of NASA’s James Webb Space Telescope – a revolutionary observatory, 100 times more powerful and the scientific successor to the Hubble Telescope. When launched, Webb will reveal a universe we have never seen before and is poised to answer questions that have intrigued us for thousands of years: How did the universe begin? Where did we come from? Are we alone? Armed with dynamic scenes of construction, fascinating conversations with scientists and engineers and stunning visuals, Into the Unknown offers an in-depth look at one of the most daring scientific missions ever attempted. A story for all ages, this film captures the wonder of the cosmos and the timeless human desire to understand our place within the universe. The Northrop Grumman Foundation, in partnership with filmmaker Nathaniel Kahn, developed this documentary as a resource for teachers, students and space enthusiasts around the world to enjoy.

Today we will begin our look at the spaceships we might use for colonizing interstellar space in the future. In order to cover the vast distances between even the nearest stars in our galaxy within the boundaries of known physics, we need vessels able to voyage at high speeds for very long periods of time while carrying everything they need to colonize another solar system, a concept typically known as a space ark or generation ship. We will explore the challenges and options for such a vessel, as well as some alternative approaches to the problem. "The World, The Flesh And The Devil" by J.d.

Text in 'How far away is it - Supernovae and Star Clusters' document http://howfarawayisit.com/wp-content/uploads/2018/06/Star-Clusters-and-Supernova-v2-1.pdf In this segment of our “How far away is it” video book, we cover Supernovae and star clusters. As we start Supernovae, we compare the magnitude of the exploding star that created the Helix Planetary Nebula with the explosion that created the Crab Nebula. We take the opportunity to describe the size and densities of White Dwarfs as compared to Neutron Stars. We also take a look at what the daytime sky might look like if Betelgeuse were to supernova. We then cover the Neutron Star that that a star supernova leaves behind. We take a deep look at the Crab Nebula’ Neutron star. We then take a look at the beautiful Veil Nebula and the Cygnus Loop. We then explain what a Type 1a Supernova is and how it works as a critically important standard candle. We show a binary star system with matter flowing through the L1 Lagrange point, and mention Subrahmanyan Chandrasekhar’s solution to Einstein’s equations. We then take a look at the amazing remnants of past supernova explosions scattered across our galaxy including: SN 1006, RCW 86, Tycho Supernova SN 1572, Cassiopeia A with its Light Echoes, RCW 103 with its Magnetar, Kepler's supernova SN 1604, N 63A, and Supernova 1987A. For RCW 103, we illustrate the impact on the Earth if it were Capella that went supernova. We conclude this section on SN with a look at how we find them with transient facilities like the Zwicky Transient Facility at the Palomar Observatory. We continue on to Star Clusters by pointing out that there are two primary kinds of star clusters: open cluster and globular cluster. We visit some very beautiful open clusters including: the Pleiades, the Jewel Box (NGC 4755), Pismis 24 in NGC 6357, Terzan 5, NGC 6791, and the Quintuplet and Arches clusters. And then we visit some spectacular globular clusters including: 47 Tucanae, Omega Centauri, Terzan 5, M30 and M53. We conclude by adding brightest globular clusters and Type 1a Supernova as key standard candle rungs on our distance ladder.

Try out Ecosia and support reforestation: https://ecosia.co/isaacarthur Technology may one day grant us a Utopia in which virtually all tasks are performed by robots and artificial intelligence. In such a post-scarcity civilization, people may have difficulty finding a purpose to existence. Today we will explore how this may come about, what the consequences of this existential threat might be, and what purposes people may find for themselves in such a future.

Text in 'How far away is it - Planetary Nebula document at: http://howfarawayisit.com/wp-content/uploads/2018/06/Planetary-Nebula-v2-1.pdf In this segment of our “How far away is it” video book, we cover Planetary Nebula. We begin by introducing astrophotography and how it adds to what we can see through a telescope with our eyes. We use NGC 2818 to illustrate how this works. This continues into the modern use of Charge-Coupled Devices and how they work. We use the planetary nebula MyCn18 to illustrate the use of color filters to identify elements in the nebula. We then show a clip illustrating the end-of-life explosion that creates objects like the Helix Planetary Nebula (NGC 7293), and show how it would fill the space between our Sun and our nearest star, Proxima Centauri. Then, we use the Cat’s Eye Nebula (NGC 6543) to illustrate expansion parallax. As a fundamental component for calculating expansion parallax, we also illustrate the Doppler Effect and how we measure it via spectral line red and blue shifts. We continue with a tour of the most beautiful planetary nebula photographed by Hubble. These include: the Dumbbell Nebula, NGC 5189, Ring Nebula, Retina Nebula, Red Rectangle, Ant Nebula, Butterfly Nebula, , Kohoutek 4-55, Eskimo Nebula, NGC 6751, SuWt 2, Starfish, NGC 5315, NGC 5307, Little Ghost Nebula, NGC 2440, IC 4593, Red Spider, Boomerang, Twin Jet, Calabash, Gomez’s Hamburger and others culminating with a dive into the Necklace Nebula. We conclude by noting that this will be the most likely end for our Sun, but not for billions of years to come, and we update the Cosmic Distance Ladder with the new ‘Expansion Parallax’ rung developed in this segment.

The possibility that ancient civilizations might have encountered or even been influenced by extraterrestrials has fascinated us for as long as we knew there were distant suns they might visit from. Today we will examine the evidence and consider the numerous scenarios form the perspective of the Fermi Paradox, to see how reasonable the Ancient Aliens hypothesis is, and ask if the evidence of UFOs visiting us in the past is credible.

To see deeper into space, we will need much bigger telescopes. Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ As astronomy seeks to find and study distant planets and peer further and more accurately into space and time, the limitations of ground based telescopes, especially optical telescopes, represents our largest barrier. Today we will examine what those limitations are, and ways to make vastly more enormous telescopes and arrays.

Subscribe to Naked Science – http://goo.gl/wpc2Q1 Where does a cup of coffee come from? In this film, it’s not Starbucks, it’s stars busting. We go right back to the beginning of time to show where the ingredients in your cup of coffee were born. The main ingredient is hydrogen; it makes up most of the water in your cup. And that formed in the big bang. How it got from there, into your cappuccino is one of the most dramatic stories in science. It has taken thousands of scientists to track its trail. We follow it through stars and galaxies, exploding supernovae, and giant clouds of gas to show just how it reached your cup. But that isn’t the end of the story. For where it goes in the future, depends on the fate of the universe. Will it carry on expanding for ever, or tear itself apart?

And we come to the end of our punt through the waters of the Saturn system, with an examination of its smaller moons CORRECTIONS: 13:49 : Water reacts with the crust, causing the crust to combine with the oxygen in the water and hydrogen to be released. 18:20 : Lagrange points are similar to hills; some are low, rolling and stable, others are narrow and sharp, and require constant readjustment to retain position. 22:32 : As can be plainly seen in the diagram, Iapetus's inclination is over 15 degrees, not 7. To be honest I can't remember where I came up with that one.

It’s possible that in a few centuries Humans may be able to capture all the energy on Earth, in a few thousand years we might be able to capture all the energy from the Sun, and we might be able to harvest all the energy from every star in our galaxy in 100,000 to one million years. In this video, we discuss the Kardashev scale and look in detail on each civilization type, as well as discussing Dyson spheres. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by: David ►Share this video: https://youtu.be/D2GGI3u_RRg Music: “So Many Stars” by Miguel Johnson “A Memory of Earth” by Markus Junnikkala “Staring Through” by AJ Prasad

If you want to blame anyone for Pluto's demotion, you can always blame the Martians. Sorry, everyone. I had to re-reupload this; I made a careless edit that screwed with the audio-visual sync. Planet X playlist: https://www.youtube.com/watch?v=EgEimO_M7bE&list=PLa0TgREKn12jjme25mOy_x_GyKPaRL7aU

Where did the odd word "planet" come from? And what was it originally meant to define? Here we look at how the planets were discovered. [A reupload of an earlier video to correct an error]

Would you forego everything, the feel of the sun on your face, the taste of cherries, the smell of a fresh morning, for more efficient computers? These guys think so, and they think that's why we haven't found aliens.

We explore the history and future of missions to Mars Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ You can see part 1 here: https://youtu.be/Pv7aigOzQKo For years following the Moon landings it seemed liked Mars would be our next step and sooner than later, but the costs and risks discouraged interest for around a decade after that. We pick up from part 1 when renewed interest arose and examine many of the more recent plans and what options they give us for manned missions to the Red Planet in the next decade.

We often think of colonizing or even terraforming a planet, but how about colonizing every planet in your galaxy, and not by spaceships but by self replicating machines. In this episode, we will be looking at von Neumann probes, discussing many reasons why you’d use them, tied in with the Fermi paradox. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by: David ►Share this video: https://youtu.be/SEziF9P8ZZc Music: “Cylinder Five” by Chris Zabriskie “A Memory of Earth” by Markus Junnikkala
