Cosmic Journeys - Mars- Earth that Never Was

The Hunt for Life on Mars - Looking for Life Beyond Earth and the Universe Documentary

In the late 1970s, two Viking robots sailed to Mars, pillaged the soil and burnt any traces of life they found.
That was never the plan, of course. When NASA first landed the twin spacecraft named Viking 1 and Viking 2 on the surface of Mars 40 years ago, scientists were ecstatic to finally start studying Martian soil for signs of organic (carbon-based) molecules that could prove the Red Planet was hospitable for life. It should've been a slam-dunk mission. The pockmarked face of Mars was constantly being pelted with tiny, carbon-rich meteorites, after all — detecting signs of that carbon was thought to have been a sure thing.

The Search for Signs of Life on Exoplanets - Finding Other Habitable Planets in the Universe

After nine years of operation, NASA's Kepler spacecraft will be retired, but not without making an indelible imprint on humankind's understanding of the universe. Perhaps its greatest legacy is the knowledge that planets outnumber stars in the galaxy. With over 2,500 planet discoveries and another 2,000 awaiting confirmation, Kepler revealed a staggering diversity of worlds turning sci-fi fantasy into scientific reality.
It also changed our collective perspective regarding the feasibility of finding evidence of life beyond Earth and catalysed efforts across the globe to reach that goal.

Living Universe | Journey To Another Stars - Documentary 4K

The Earth is Not Alone:
LIVING UNIVERSE is an interstellar adventure that seeks to answer the most profound question of all: are we alone? Based on the latest scientific knowledge, we will take a journey to a planet beyond our solar system in search of life.

We ask the world's leading space scientists what we might find if we travel to a neighboring star system. Recent breakthroughs have proven that every star we see in the sky is orbited by at least one planet, many similar to our own Earth. How do we get to these exoplanets? Once there, what will we find? And what will it mean for humanity when we discover we are not alone?

Our speculative journey through space is set a hundred years in the future - when we have the technology to journey well beyond our solar system. On this first expedition, our star ship Aurora will be piloted not by astronauts, but by the artificial intelligence (A.I.) we call Artemis. We imagine how Artemis travels through space, on its 25-year journey, at one fifth of the speed of light. Its objective is Minerva B, a planet much like our own, with an atmosphere, temperature and liquid water that appears a likely candidate to contain life.

With spectacular special effects we will reach and explore a new planet as we seek to answer the most profound question of all: are we alone in the universe? Our guides on this journey are narrator Dr Karl Kruszelnicki and as the voice of our AI, Artemis, real-life astrophysicist, Professor Tamara Davis.

Inspired and informed by our rapidly developing knowledge of far-off worlds, our best scientists - including NASA engineers, astrophysicists and astronomers - we will discover that this amazing journey is not only possible, it is inevitable. To venture into distant space is our destiny.

LIVING UNIVERSE captures a pivotal moment in the human story. A film full of insight and inspiration certain to thrill anyone who dreams of distant worlds, or have ever wondered why are we here?

Have you ever wondered that someone like you, sitting less than a mile away, in some other universe, exists? The possibility in itself seems frightening as well as astonishing.

From breaking news and intriguing historical documentaries to conspiracy theories, classified NASA files and UFO's. We provide you with material that the government doesn't want you to see. The Insomnia team comes up with a promise. To keep up with the same, the team now brings to us a documentary that aims to change your perspective Of another existence, of another possibility, as today, the scientists now believe there may really be the presence of a parallel universe - and in fact, also believe that there may be an infinite number of parallel universes, and where we live today just happens to be only one of them and many of these other parallel universes come with different laws of physics as well.

These other universes that we are talking about not only contain space, time and strange forms of exotic matter but to surprise you, Some of them may even contain you, only maybe in a slightly different form. The thought itself is quite intriguing and scary on the same hand. The basis of this theory is as we know it the idea that parallel universes are constantly spinning off from reality that we humans know of. Though generally ignored at the time, that theory has gone on to become not just a popular topic of study among respected physicists, but the inspiration for such popular films, television shows, and books as Star Trek and The Golden Compass. according to the sources.

The video soon progresses into the Wilkinson Microwave Anisotropy Probe (WMAP), that is now changing everything, as some say that the remarkable images reveal the true shape of the universe through baby pictures of the same from the time when it was 4 hundred thousand years old, looking so back in time, when there wasn't even the formation of galaxies yet. The WMAP is catching the very first signs of creation as it is officially tagged with measuring radiation that is left over from Big Bang. And now scientists have devised an experiment to find the overall true shape of the universe. The WMAP hence shows that the universe is flat. From here arises the possibility of more mind boggling parallel universe that are of the level-2 type and is made up of giant cosmic soap bubbles that float in hyperspace. Each of these bubbles within it has a whole universe. Now, the question that arises is that - Do we all live in a giant cosmic bubble?

Interstellar Journey To The Stars (Quantum Transportation) - Space Documentary [HD]

How hard is it to hop to the nearest star system or soar across the galaxy? A typical Star Trek or Star Wars movie makes it look easy. When the heroes get a distant distress call, they use warp drive or hyperdrive and arrive at their destination within minutes or hours. If we got the right propulsion, would it be possible for us to voyage that quickly in real life?

Almost 50 years ago, humans were walking on the moon. But we stopped going in 1972 and never ventured any farther, except by sending robotic probes. Humans have never gone to Jupiter, as the book and movie 2001: A Space Odyssey promised us, or even to Mars. What is it that makes travel far away so difficult? Besides the obvious human health concerns (living in microgravity tends to weaken a body over time) and budgetary issues, there are vast technological problems with traveling to faraway places. Space exploration will be covered in AMC Visionaries: James Cameron's Story of Science Fiction, which runs its second episode tonight (May 7).

While experts are working on interstellar travel concepts, they warn that our expectations of instantaneous travel are probably too high. The problem with most of the science fiction faster-than-light travel is [that] it makes a tremendously difficult thing seem as if it's very easy, warned Geoffrey Landis, a NASA scientist and science fiction author who has worked on the problem of interstellar propulsion.

Accelerating a spacecraft with pure energy would take a lot of propulsion, not to mention that you would eventually run into a speed limit. According to physics laid down by& Albert Einstein's general theory of relativity a century ago, as an object approaches the speed of light, its mass reaches infinity. So, in other words, a spacecraft couldn't physically go as fast as light.

Some science fiction stories (such as the 1962 children's book A Wrinkle in Time, which was recently released as a film in theaters) use wormholes to get around the problems with instant travel. But wormholes also have issues. It's hard to figure out how to get enough mass in one place to create one, although black holes are a leading candidate. Then there are the problems of figuring out how to hold wormholes open and how to safely traverse them.

And whether you travel near the speed of light or use a wormhole, you would likely run into the phenomenon of time dilation. As a spacecraft moves at speeds approaching that of light, occupants would age at a slower rate than their friends and family back home, Einstein's theory of special relativity shows. So, people on a long voyage may return to find their loved ones greatly aged, or dead.

Even astronauts on the International Space Station experience the effects of time dilation (to a much smaller extent) upon returning to Earth. This happened to astronaut Scott Kelly after he spent nearly a year in space between 2015 and 2016. When he came home, his age gap over his twin, Mark Kelly, had increased by 5 milliseconds.
Real-life interstellar travel
Interstellar travel is still possible, but as far as we know, the best option is to think fairly local for now. The nearest star system to us is Alpha Centauri. In 2016, scientists discovered an Earth-size planet in the habitable zone of one of Alpha Centauri's stars, a red dwarf called Proxima Centauri. (There's debate about whether Proxima Centauri's stellar activity has too much radiation for life to exist on its planet, but the jury is still out on that.)

Alpha Centauri is close enough to be intriguing: just about four years away if you travel at the speed of light. But at slower speeds, it's still pretty far. If the Voyager 2 spacecraft (which launched in 1977 and breached interstellar space in 2012) had gone in that direction, it wouldn't reach Alpha Centauri for another 75,000 years. We'll need a quicker solution.

Back in 1998, one of Landis' interstellar concepts was funded by NASA's Innovative Advanced Concepts (NIAC) program; NIAC examines far-out ideas for space exploration that may not be used for decades. In essence, Landis' proposal suggested using lasers to push a spacecraft equipped with sails, building on ideas published by physicist Robert Forward in 1984. The concept was later picked up by the Breakthrough Starshot group, which in 2016 announced that it hopes to eventually send mini-spacecraft to Alpha Centauri.

Landis said his idea would work for people, but unless you made the spacecraft very small (as Breakthrough proposes doing), you would not get to Alpha Centauri quickly. It's only if you send a very small probe, he told Space.com, that you could make it smaller and faster, and perhaps get to the nearest star in something less than a lifetime.

A Journey To Mars - Space Documentary

NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s – goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010. Mars is a rich destination for scientific discovery and robotic and human exploration as we expand our presence into the solar system. Its formation and evolution are comparable to Earth, helping us learn more about our own planet’s history and future. Mars had conditions suitable for life in its past. Future exploration could uncover evidence of life, answering one of the fundamental mysteries of the cosmos: Does life exist beyond Earth?

The Earth is Not Alone - Space Documentary HD

People began traveling in space in 1961 in tiny spacecraft called capsules, which were launched from Earth by powerful rockets. Russian crews still travel in this kind of craft, in Soyuz capsules, but Americans now travel into space in shuttles, which are rocket-powered space planes.

HOW DO HUMANS SURVIVE IN SPACE?
There is no oxygen in space, so all crewed spacecraft carry a life-support system. This supplies air for people to breathe. The system also includes equipment to keep the air at a comfortable temperature and pressure and to remove carbon dioxide and odors.

HOW DOES SPACE TRAVEL AFFECT PEOPLE?
Gravity in space is much weaker than it is on Earth. When people travel in space, they seem to become weightless. This often makes them feel sick. Their bodies do not have to work as hard, because they are not fighting gravity to sit or stand up. If they stay in space for a long time, the lack of gravity makes their muscles start to waste away. Exercise and a special diet help to combat these effects.

WHAT IS THE FARTHEST ANYONE HAS TRAVELED IN SPACE?
Astronauts on the APOLLO PROJECT traveled to the Moon, about 239,000 miles (385,000 km) away. Russian cosmonaut Valeri Poliakov traveled a distance of about 174 million miles (280 million km) around Earth while in the Mir space station.

APOLLO PROJECT
In the space race of the 1960s, the US Apollo Project beat the Soviet Union by landing the first astronauts on the Moon. The first Moon landing, by Apollo 11, took place on July 20, 1969, when Neil Armstrong and Buzz Aldrin became the first humans to set foot on another world.

WHAT WAS THE APOLLO SPACECRAFT LIKE?
The Apollo spacecraft was launched from Earth by the Saturn V rocket. On the launch pad, the whole assembly stood 365 ft (111 m) tall. The spacecraft itself weighed 50 tons (45 metric tons). It was made from three main modules (sections). The command module for flight control housed the three-person crew. The service module carried equipment, fuel, and a rocket motor. The lunar module detached from the craft and landed two astronauts on the Moon’s surface.

HOW MANY APOLLO LANDINGS WERE THERE?
There were six Moon landings, beginning with Apollo 11 in July 1969 and ending with Apollo 17 in December 1972. During the missions, 12 astronauts explored the lunar surface for a total of over 80 hours and brought back nearly 880 lb (400 kg) of Moon rock and dust for examination on Earth.

Mars Calling: Manifest Destiny or Grand Illusion

This film brings together the mythic and the scientific to show that Mars may not be what we imagine. Some believe Mars is the next home for Humanity. But the real “red planet” is a trickster; strikingly beautiful, yet sweetly sinister. Even as a growing armada of instruments arrive, this small cold world continues to conceal its secrets. The technological means to cross space and perhaps bring this small world back to life is just now coming within our grasp. Settlers beware: Mars is likely to change Humanity as much as we change it.

ANOTHER EARTH | KEPLER 186F - Full Documentary

If Alien exist where do they live and how do they live?
Scientists say a world that's 490 light-years away qualifies as the first confirmed Earth-sized exoplanet that could sustain life as we know it — but in an environment like nothing we've ever seen.
The planet, known as Kepler-186f, is more of an Earth cousin than an Earth twin, Elisa Quintana, an astronomer at the SETI Institute at NASA Ames Research Center, told the journal Science. Quintana is the lead author of a report on the planet published by Science this week.
This discovery does confirm that Earth-sized planets do exist in the habitable zones of other stars, Quintana said during a Thursday news briefing at NASA Headquarters.
Kepler-186f goes around an M-type dwarf star that's smaller and cooler than our sun. But it orbits much closer to its parent star than Earth does, within what would be Mercury's orbit in our own solar system. Those two factors combine to produce an environment that could allow for liquid water on the surface, assuming that the planet had a heat-trapping atmosphere.

The star, to our eyes, would look slightly orange-y, about a third again as big as our sun but only a third as bright, said co-author Thomas Barclay, a staff scientist for NASA's Kepler mission who is also affiliated with NASA and the Bay Area Environmental Research Institute. At midday, Kepler-186f's landscape might look similar to what we see on Earth an hour before sunset, he told NBC News.
Or it might not: If the planet lacked an atmosphere to retain and redistribute its sun's warmth, it would be a cold, dry, lifeless world.

Kepler-186f probably rates as the most potentially Earthlike planet discovered so far, said Jim Kasting, a geoscientist at Penn State University who did not play a role in the Science study. But he told NBC News that it's still less likely to be habitable than planets around more sunlike stars. Even better prospects for alien habitability might well be identified in the months and years to come.

How the world was found

Kepler-186f is just the latest discovery to be pulled out of terabytes' worth of data collected by the Kepler mission. Before it went on the fritz last year, the Kepler space telescope stared at more than 150,000 stars in a patch of sky, looking for the telltale dimming of starlight as planets passed over the stars' disks. Nearly 1,000 exoplanets have been confirmed using Kepler data, and almost 3,000 more candidates are still awaiting confirmation.

It takes years of observation to confirm the pattern of dimming and brightening that's associated with alien planets, particularly if the planets are small and far from their parent stars. In February, astronomers reported that at least four worlds circled the dwarf star known as Kepler-186 or KOI-571. In this week's Science paper, Quintana and her colleagues confirm the existence of Kepler-186f as the fifth and outermost world.
They report that Kepler-186f is about 10 percent wider than Earth, tracing a 130-day orbit around its sun at a mean distance of 0.35 astronomical units. (An astronomical unit is the distance between Earth and our sun, which is 93 million miles or 150 million kilometers.) That would put Kepler-186f on the cooler, outer side of the star's habitable zone — the range of orbital distances where liquid water could exist on a planet's surface.

Astronomers have confirmed the existence of other planets in their stars' habitable zone, but those prospects are super-Earth-size. Smaller habitable-zone candidates also have been found, but they have yet to be confirmed as planets.

Barclay said Kepler-186f was particularly promising because it's less than 1.5 times the size of Earth. Planets in that size range are more likely to be rocky with a thinner atmosphere, like Earth, Mars and Venus. But worlds exceeding that size stand a better chance of retaining a thick atmosphere of hydrogen and helium, like the giant planet Neptune.

While those planets also could be rocky, they don't remind us of home, Barclay said.
Could we actually detect signs of life on Kepler-186f? That's a tough one. The astronomers behind the discovery acknowledge that the planet might be just too far away for follow-up studies. The SETI Institute has been searching for radio signals from the Kepler-186 system over a wide frequency range (1 to 10 GHz), but so far nothing has been detected.
