| Interstellar travel | Space documentary 2020 |

Interstellar travel is crewed or uncrewed travel between stars or planetary systems. Interstellar travel would be much more difficult than interplanetary spaceflight. Whereas the distances between the planets in the Solar System are less than 30 astronomical units (AU), the distances between stars are typically hundreds of thousands of AU, and usually expressed in light-years. Because of the vastness of those distances, practical interstellar travel based on known physics would need to occur at a high percentage of the speed of light, allowing for significant travel times, at least decades to perhaps millennia or longer.
The speeds required for interstellar travel in a human lifetime far exceed what current methods of spacecraft propulsion can provide. Even with a hypothetically perfectly efficient propulsion system, the kinetic energy corresponding to those speeds is enormous by today's standards of energy development. Moreover, collisions by the spacecraft with cosmic dust and gas can produce very dangerous effects both to passengers and the spacecraft itself.
A number of strategies have been proposed to deal with these problems, ranging from giant arks that would carry entire societies and ecosystems, to microscopic space probes. Many different spacecraft propulsion systems have been proposed to give spacecraft the required speeds, including nuclear propulsion, beam-powered propulsion, and methods based on speculative physics.

The Search For A Second Earth - Space Documentary HD

In the 400 years since Galileo Galilei first held a telescope to the heavens, astronomers have laid bare some of the deepest mysteries of the cosmos. They have seen comets crash into planets, found oceans inside moons, and witnessed the shudder of spacetime as black holes collide.

But space remains a realm of the unknown. Writing in the journal Nature on Thursday, scientists in Canada reported the detection of mysterious radio signals from halfway across the universe. It is only the second time that repeating fast radio bursts, or FRBs, have been spotted.

Astronomers have yet to formulate a full theory of what produces these enigmatic, rapid-fire beams of electromagnetic waves. And in the absence of a firm explanation, speculation has fallen, perhaps inevitably, on alien civilisations. Avi Loeb, a Harvard astronomer, has proposed that FRBs might be powerful energy beams used to propel alien spacecraft.

It is not the first time that poorly-understood cosmic phenomena have been ascribed to industrious extraterrestrials. When in 2015 astronomers noticed a star, 1,500 light years distant, dimming and brightening, researchers suggested an “alien megastructure” might be revolving around it, and collecting energy for its constructors. Then, in 2017, the massive cigar-shaped ‘Oumuamua barrelled into the solar system, the first interstellar object known to do so, and prompted speculation that it was a tumbling spacecraft.

Chris French, head of the Anomalistic Psychology Research Unit at Goldsmiths, University of London, said it was natural for humans to see aliens behind every cosmic mystery. “We have what is called an intentionality bias,” he said. “It’s the assumption that whenever something happens, something or someone made it happen for a reason. In the context of space, that someone is always going to be aliens.”

The evolutionary argument for intentionality bias, or “agenticity”, is that our ancient ancestors fared better if a rustle in the bushes made them run for cover rather than assume it was the wind. “At the end of the day, our brains evolved to keep us alive rather than apprehend the truth of the universe,” said French.

The late astronomer Carl Sagan spotted the dilemma for scientists. They can become cranks if they are too open-minded, but may miss out on landmark discoveries if they are not open-minded enough. “It seems to me what is called for is an exquisite balance between two conflicting needs,” he said. “The most sceptical scrutiny of all hypotheses that are served up to us and at the same time a great openness to new ideas.”

Duncan Lorimer, an astrophysicist at West Virginia University, discovered the first FRB in 2007. When his team spotted the radio burst, the possibility of it being a message from ET certainly came up. “We absolutely thought about aliens,” he said. “We only had the one object. We looked for patterns in the signal and couldn’t find anything, but we definitely considered it.”

Now, mention of aliens is beginning to wear thin. “It helps to sell the story, but at this point I do roll my eyes a bit,” he said. Many astronomers now favour the idea that FRBs are intense beams of radiation shed by charged particles as they are whipped around by strongly magnetised neutron stars. “It seems like a more plausible idea, but I don’t want to rule out aliens completely,” he said. “I’ve been wrong before.”

The Search For A Second Earth - Full Space Documentary

U.S. space agency NASA announced the discovery of more than 200 new planets on Monday, 10 of which are believed to be about the right size and temperature to support life.

Of the 219 new suspected planets to have been discovered by NASA's Kepler telescope, 10 were found to exist in the so-called 'Goldilocks zone' of their solar system. This refers to the distance between the planet and their star, which is neither too hot nor too cold to support complex life.

The presence of liquid water on these rocky Earth-like planets is seen as a key ingredient required for the existence of life.

Are we alone? Maybe Kepler today has told us indirectly, although we need confirmation, that we are probably not alone, Mario Perez, Kepler program scientist, said at a news conference.

NASA launched the Kepler telescope in 2009 in a bid to discover whether other Earth-like planets are common or rare.

The latest identification of suspected exoplanets – planets outside our own solar system – brings the tally discovered by the Kepler telescope to 4,034. The number of worlds thought to be approximately the same size and temperature as Earth is around 50.

Is Interstellar Space Travel Possible? Can we travel to other planets and stars?

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?

UFOS & ALIENS - The Myth Of Space Travel | SPACETIME - SCIENCE SHOW

For more than 40 years, people have lived in space over longer periods of time - first on the space stations Saljut and Skylab, today on the international space station ISS, and perhaps soon in a spaceship on its way to Mars. But man is not made for space. The universe is so hostile to life that humans can not survive there permanently. Skeptics, conspiracy theorists claim that all manned space travel is just a well-staged drama and the moon landing is the biggest lie of all. Since man has set out to conquer outer space and then the universe, conspiracy theorists accompany the work of scientists and explorers. And at the same time, UFOs (unidentified flying objects) have been sighted with claims of visits by your favorite martian aka extraterrestrials. Mankind’s advance into space has triggered the imagination of earthlings since humans first looked up at the stars. And so, in addition to the epochal discoveries, countless myths and legends have arisen as well.

The world is not enough for conspiracy theories. Since the first launches into space numerous myths and legends around space travel and astronauts abounded. The first images from space depicted our planet in spherical form. All lies was a cry heard immediately from so-called experts.: The earth is and remains a disc. To this day, there are advocates of the flat earth theory, which was actually refuted even before the birth of Christ.

The claim that the earth is flat was almost extinct, but the Internet is helping fuel this theory in a kind of renaissance of fools. Any kind of conspiracy theory ever invented in the context of space travel is getting a revival in the age of the world wide web. The biggest of all is the denial of the successful landing of man on the moon.

Hardly any other human event spawned such wild speculation as Neil Armstrong's moon landing as well as the eleven other US astronauts. Just a few months after the first steps on the Moon, skeptics accused NASA, its scientists and astronauts, and the entire US government as liars. The landing never took place, the live images were recorded in Hollywood studios, the whole moon program is a huge bluff. To this day, despite proof to the contrary, the conspiracy theorists continue to beat the drum of denial.
But there is also a lot happening on planet Earth. Ever since man conquered space, first with balloons and then with airplanes, earth dwellers regularly sight unknown flying objects: UFOs. The first UFOs were reported at the end of the 19th century; at about the same time as the first attempts to launch aircraft heavier than air into the sky. The UFOs levitate alien creatures on Earth to collect humans as research objects or to keep in contact with the powerful leaders of the world. There’s more: US military are thought to have captured several extraterrestrials and keep them hidden in a secret facility, including the flying saucers they landed with. The site: A US Air Force test site in the Nevada desert known as Area 51.
But even everyday problems and phenomena of manned and unmanned space travel repeatedly create fodder for skeptics, doubters and conspiracy theorists. Sci Fi movies are also fantastic sources for creating new myths and legends.
In this Episode of Spacetime we try to shed some light on the dark realm of conspiracies, myths and legends. Astronaut Ulrich Walter explains what really happens to people in space, should they find themselves without a spacesuit. He shows us how to live and survive in weightlessness and why even flights deep into the solar system do not have to be lethal to humans. We look at what UFO sightings are all about and what's behind them and why Area 51 is so mysterious.
We examine the surface of Mars, which appeared on the first photos of the Red Planet and terrified crowds of people. We explain the function of the warp drive and whether you can really travel through the universe with it. And of course we explain why man actually set foot on the moon.

Risky Space Travel - Danger in Space | SPACETIME - SCIENCE SHOW

SPACETIME - SCIENCE SHOW: Space, John F. Kennedy once said, is the new ocean. And for more than half a century now, man has been exploring this ocean. In doing so he is moving in a deadly environment characterized by cold, heat, and cosmic radiation. But one of the biggest dangers in space was put there by man himself: space debris poses a threat to astronauts and satellites.
If one of these fragments were to hit the ISS, the international space station, it could have devastating consequences - even the demise of the whole crew.
Hundreds of thousands of these fragments are hurtling through the Earth’s orbit at an estimated speed of eight kilometres a second, and every one of them could cause a disaster.
Ever since space flight began man has also left his refuse behind in space. Satellites, spacecraft, and the International Space Station are permanently at risk of being hit, damaged, or even destroyed by particles of scrap. Astronauts are also at risk from cosmic radiation. Our sun, too, can mean death for humans in space.

NASA’s Voyager 2 Enters Interstellar Space

Forty-one years after it launched into space, NASA’s Voyager 2 probe has exited our solar bubble and entered the region between stars. Its twin, Voyager 1, made this historic crossing in 2012. Edward Stone, the Voyager mission’s project scientist, and Suzanne Dodd, the mission project manager, discuss this major milestone and what’s to come for the trailblazing probe. For more about the Voyagers, including the Grand Tour of the Solar System and the Golden Record, visit

Why Harvard Scientists Think This Object Is An Alien Spacecraft

Harvard scientists think that the first interstellar object detected in our solar system, called “Oumuamua,” could be an alien spacecraft. The scientists sought to explain a quirk in Oumuamua's behavior, which led them to an unusual conclusion. No one knows what Oumuamua is or where it came from, and it's too late to find out for sure.

The Ending Of Interstellar Finally Explained

Directed by Christopher Nolan, Interstellar is a fantastic tale of time, space, and love. But if you got a bit lost in the final act of the film, we wouldn’t blame you. So let’s do our best to walk through the bizarre, mind-bending ending of Interstellar.

Life on Earth isn't great in Interstellar. Massive dust storms are tearing up the planet, crops are failing, and soon, humanity will cease to exist. Looking for answers, NASA turns to the skies, hoping for some kind of insight.

As we learn at the beginning of the film, a group of 12 scientists traveled through a mysterious wormhole that appeared near Saturn, to see if the 12 planets on the other side could sustain human life. A few years later, the Endurance and its crew including Matthew McConaughey's Cooper and Anne Hathaway's Brand are going to visit the three most promising planets in the hopes of colonizing one. When they arrive on Dr. Mann's planet, the heroic scientist assures them his icy cold spot is the perfect place for humans to live.

Unfortunately, it's soon all revealed to be a ruse. Although each of the original 12 scientists knew their trip was one-way, Mann admits he never fully considered the possibility that his planet would be uninhabitable, and that he might die alone. Although he resisted the urge for years, he eventually falsified his survey data to coax another team to travel to his planet, intending to use the Endurance to escape.

At this point, Mann is so desperate to leave that he'll do anything, even kill. Paranoid that the Endurance crew won't go along with his plan once they learn what he's done, Mann attempts to kill Cooper so he can make his getaway.

Back on Earth, Cooper's now-grown children find themselves at odds. His daughter, Murph, played by Jessica Chastain, has realized the surface of our planet has become uninhabitable. So naturally, she's trying to persuade her brother, Tom, to bring his family to the secret NASA facility where she's been working on the gravitational equation that would allow humanity to escape into space en masse.

But despite Murph's warnings, Tom refuses to abandon the farmhouse where they grew up. After Cooper left them in their grandfather's care when they were children, never to be heard from again, Tom lost all faith in NASA's ability to help them. Keep watching the video to see the ending of Interstellar finally explained!
