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.

How was the expansion of the universe discovered? What does the Vatican observatory do? Brother Guy Consolmagno the director of the Vatican Observatory joins John Michael Godier on Event Horizon to discuss the Vatican's rare meteorite collection. As well as the type of astronomy they conduct and how the observatory was founded.

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?

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?

As the longer stretches of the electromagnetic spectrum have repeatedly turned up dry, the Search for ExtraTerrestrial Intelligence has gradually shifted to higher and higher frequencies, and have recently crossed into the domain of our eyes.

Go to https://buyraycon.com/isaacarthur for 15% off your order! Brought to you by Raycon. The Search for Extra-Terrestrial Intelligence, SETI, relies on looking for signals from distant alien worlds where even very powerful signals can weaken to near nothing. We'll explore today how we, or extraterrestrials, might get around this problem, be it by immense star-powered transmitters or by using laser communication beams.

Is life on Europa? Did Mars have life? Does Mars currently have life on it? NASA Chief Scientist Dr. Jim Green joins John Michael Godier to discuss NASA's plans for Mars 2020, the possibility of past and current life on Mars. As well as the fact that the solar system may be full of life as much of the moon's and Kuiper belt objects have large amounts of water on them. Does Europa have complex life? It has an ocean of water underneath it's surface more than the combined amount of water on Earth. The Europa Clipper mission will do its best to answer that.

Uranus is the third largest planet in the solar system and a huge ball of gas. 64 terrestrial spheres would fit inside it. It is very far away from us, twice as far as Saturn! Uranus moves around the sun at a distance of about 2.8 billion kilometres! Therefore, it takes 84 years until it completes one complete orbit, thus completing one Uranus year. Uranus consists mainly of the gases hydrogen, helium and methane. The methane gives it its bluish colour. There is probably a solid iron core in its interior. The Earth is not a perfect sphere either, but the difference between the equatorial and polar diameters is minimal compared to that of gaseous planets. Uranus moves far away from the earth around the sun. It is not a conspicuous object in the sky. Basically, you can only find it if you know exactly where to look. It looks like a pale and inconspicuous star. #uranus #discoveringspace #nasa ---- This channel offers you full episodes of high quality documentaries.

Four billion years ago, Venus, Earth and Mars each held the promise of supporting life, with oceans, supportive climates, and the chemical ingredients of biology. Over the eons since, Mars lost its atmosphere, turning ever colder, while Venus entered a death-spiral of ever-increasing heat. But, 50 km above its desolate surface, the cool cloud tops of Venus offer a potential refuge. This zone is protected from cosmic and solar radiation overhead and the blistering surface temperatures below.  Solar powered ships and habitats could effortlessly float there, sailing the brisk winds that circle the globe. That has inspired visionary engineers and scientists to take the first steps toward settling the 2nd planet from the Sun.

51 years ago, the historic Apollo 11 mission launched from Pad 39a in Cape Canaveral, Florida. Watch some amazing documentaries to celebrate! Apollo 11 was the spaceflight that first landed humans on the Moon. Commander Neil Armstrong and lunar module pilot Buzz Aldrin formed the American crew that landed the Apollo Lunar Module Eagle on July 20, 1969, at 20:17 UTC. Armstrong became the first person to step onto the lunar surface six hours and 39 minutes later on July 21 at 02:56 UTC; Aldrin joined him 19 minutes later. They spent about two and a quarter hours together outside the spacecraft, and they collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth. Command module pilot Michael Collins flew the Command Module Columbia alone in lunar orbit while they were on the Moon's surface. Armstrong and Aldrin spent 21 hours, 36 minutes on the lunar surface at a site they named Tranquility Base before lifting off to rejoin Columbia in lunar orbit. 📄 For more information about Apollo 11, click the link below https://en.wikipedia.org/wiki/Apollo_11 Make sure to: 👍 Leave a like on this video 🔴 Subscribe to Astronomy Films 🔔 Turn on notifications so you don't miss new videos or live streams 🤝 Check out my partner channels International Rocket Launches and Raw Space for amazing streams of rocket launches, NASA events, and more!

Were there prior technological civilizations in our solar system? What are some unusual and odd alien technosignatures? Jason Wright joins John Michael Godier to explore unusual technosignatures from alien civilizations. Looking for red spirals, dyson spheres, and other signs of intelligent life within the universe.
