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.

An ultra-long-wavelength radio telescope on the far-side of the Moon has tremendous advantages compared to Earth-based and Earth-orbiting telescopes, particularly a Lunar Crater telescope can observe the universe at wavelengths greater than 10m (i.e., frequencies below 30MHz), which are reflected by the Earth’s ionosphere and are hitherto largely unexplored by humans. John Michael Godier speaks with Saptarshi Bandyopadhyay about his 2020 NIAC finalist project for putting a radio telescope inside a crater on the far side of the moon.

Wormholes, passageways that connect one area of spacetime to another, are still only theoretical — but that doesn't mean we shouldn't be looking for them. Einstein's theory of general relativity predicted the warping of spacetime due to gravitational forces. When this bending becomes so strong that a region of space folds like a piece of paper, the hypothetical tunnels known as wormholes can be formed. The extreme gravitational conditions necessary for this to happen may occur around supermassive black holes. But do wormholes really exist? When taken to the extreme, gravity can create some intriguing visual effects known as gravitational lensing, that can be observed through telescopes. From the outside, wormholes can appear similar to black holes, but while moving in front of a distant star, a wormhole big enough to fit a spaceship would create a very specific type of this weird laughing mirror effect. Therefore, when it comes to hunting wormholes, looking for the distant signatures of smaller gravity lenses known as micro lenses could be the way to go. Just as optical telescopes collect visible light, so do radio telescopes collect the radio waves emitted by stars, galaxies, black holes and perhaps wormholes. Investigating ways to distinguish a wormhole from a black hole, researchers have focused on supermassive black holes with masses millions to billions of times that of the sun, which are thought to dwell at the hearts of most, if not all, galaxies. For example, at the center of our Milky Way galaxy lies Sagittarius A, a monster black hole that is about 4.5 million solar masses in size. What if such an “active galactic nucleus” (AGN) were a wormhole mouth rather than a supermassive black hole? Any matter falling into the mouth of a supermassive wormhole would likely travel at extraordinarily high speeds due to its powerful gravitational fields. The collision in the wormhole's throat of matter flowing through both mouths would result in spheres of plasma expanding from the wormhole at nearly the speed of light. Those spheres can reach temperatures of about 10 trillion degrees Celsius and would produce gamma rays with extremely high energies. In contrast, accretion disks of AGNs are too cold to emit gamma radiation. Moreover, although jets from AGNs can emit gamma rays, they would mostly travel in the same direction as the jets — any traveling out in a sphere might suggest they came from a wormhole. All in all, there are several ways in which the gamma radiation emitted by wormholes has a distinctive spectrum much different from those of supermassive black holes. An observation of such radiation would serve as convincing evidence of their existence. Researchers have also considered the possibility that wormholes can act as natural particle accelerators. The high-energy cosmic rays produced by such a scheme could be detected by sensitive radio telescopes as well. It is thought that this phenomenon may occur when a wormhole generates and maintains a magnetic field, which might also explain the observation of such fields in cosmic voids. In addition to telescopes, gravitational wave detectors could be used to detect wormholes in deep space. The United States–based Advanced LIGO, or Laser Interferometer Gravitational-Wave Observatory, as well as the Advanced Virgo detector near Pisa, Italy, have already detected ripples in spacetime caused by the merging of two black holes or dense stellar corpses called neutron stars. But scientists have also considered a black hole with a mass five times the sun’s, orbiting a wormhole billions of light years from Earth.

Magneto-Inductive Communications for Ocean Worlds, is a new concept from Dr. Robert Romanofsky of NASA. A mission to the under-ice ocean of Europa is one of the highest priority missions for NASA. Dr. Romanofsky's concept is for a probe to melt through the 5 to 10 km thickness of briny ice to reach the buried ocean below. The challenge of communicating back to the surface of Europa is also directly addressed.

Billions of years ago, our nearest planetary neighbor, Venus, may have harbored lakes, oceans, and life-giving habitats similar to those on the early Earth. Today, Venus spins slowly in a backward direction. It's a planet knocked upside down and turned inside out. Its burned-out surface is a global fossil of volcanic destruction, shrouded in a dense, toxic atmosphere. Scientists have come to see Venus as the alien planet “next door,” a laboratory for testing ideas about how planets evolve and the challenges they face in nurturing life. They are now unveiling daring new strategies to reach down to its hostile surface. From floating bases stationed high in Venus’ atmosphere, they hope to send down new generation probes to search for clues from a time when the planet was alive. How did Venus descend into this hellish state? And how did its sister planet, Earth, manage to survive?

Hubble found that clusters of galaxies produced gravitational lenses about ten times stronger and more frequent than current models of dark matter predict. This new finding by Hubble suggests that small concentrations of dark matter surrounding galaxies appear to be stronger than dark matter across galaxy clusters. It could mean there may be a missing ingredient in dark matter, or perhaps dark matter may behave stranger and stronger than we previously thought. 00:00 Start 01:52 Magellan TV shout out 02:52 What is Dark Matter? 05:58 Hubble surveys 06:50 New Hubble results 10:50 Gravitational lensing 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/r9V0J1nI8tg 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🧭 References: Meneghetti et al., 2020: https://imgsrc.hubblesite.org/hvi/uploads/science_paper/file_attachment/602/complete_manuscript.pdf ✅ Let's connect: For business inquiries - chris AT christianready DOT com Twitter - @launchpadastro Instagram - @launchpadastro Facebook - https://www.facebook.com/LaunchPadAstronomy/ Discord - https://discord.gg/yChAuUe 📭 c/o Christian Ready P.O.

Two black holes, with masses 85 and 66 times the Sun, merged into an intermediate mass black hole 142 solar masses designated GW190521. The merger was detected by the LIGO-Virgo gravitational wave collaboration. This black hole merger is considered to be "impossible" because at least one of the two black holes that merged couldn't have formed in a supernova. Instead, they belong in the "pair instability mass gap" of black holes and must have merged in a prior generation in a cluster or perhaps in a quasar's accretion disk. 00:00 Start 05:07 the GW190521 signal 09:11 the black hole mass gap problem 11:38 Solutions to mass gap problem 14:08 Alternative scenarios 16:27 Future detections 17:45 Blinkist 19:40 Patreon thanks 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/rIsGM2xkjHg 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🧭 References: LIGO Science Release: GW190521: A Binary Black Hole Merger with a Total Mass of 150 Msun (published in Physical Review Letters): https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.101102 Properties and astrophysical implications of the 150 Msun binary black hole merger GW190521: https://iopscience.iop.org/article/10.3847/2041-8213/aba493 GW190521 parameter estimation samples and figure data https://dcc.ligo.org/LIGO-P2000158/public A Candidate Electromagnetic Counterpart to the Binary Black Hole Merger Gravitational Wave Event S190521g.

Most of the planets in the Solar System have moons. We have discovered almost 200 in our Solar System alone, and so we expect that the Milky Way is teeming with moons- perhaps more moons than planets and stars. With this many, it greatly increases the number of worlds in the galaxy which could support life- and so we are keen to find them. However, they are so distant and dark that detecting extrasolar moons, or "exomoons", is a tremendous challenge.

Why is Betelgeuse dimming? The supergiant is going to end its life as a supernova. Is the sudden dimming a warning sign? Betelgeuse is a variable red super giant star located in the Orion constellation. Most estimations have it going supernova within the next 100,000 years, but could it be sooner? Dr. Andrea Dupree, associate director of the Center for Astrophysics at the Harvard & Smithsonian institute, joins John Michael Godier to discuss recent observations of Betelgeuse by Hubble.

Alberto Caballero of the exoplanets channel joins John Michael Godier on Event Horizon to discuss his concept for a new interstellar spaceship called solar one. Solar one would be the first crewed interstellar spaceship and use a combination of lasers, solar sails, and other means of propulsion to get close to 30 percent of the speed of light. Which planets and stars would be the best to go to first? The traapist system? Alpha Centauri? Tau Ceti? How often are interstellar objects like the mysterious oumuamua traveling through our solar system?
