Hunt for alien life zooms in on newly discovered solar system
Astronomers have identified seven Earth-sized planets orbiting a star that's just a mere 230 trillion miles from our own planet, raising the tantalizing prospect of life in a solar system beyond our own. Science correspondent Miles O’Brien joins Hari Sreenivasan to discuss how they made the discovery and what it means.
450,000 years ago our ancestors descended from the heavens to engineer the first human beings. To us they were Giants that ruled as Gods over mankind. Now new evidence and scientific research acknowledges their existence on earth but reveals when they will return. The truth of their real origin and purpose is much more bizarre and amazing than anything previously believed. From the Garden of Eden to the Great Flood; from the God of the Bible to the secrets of Enoch all shall be revealed.
The Year of Pluto - New Horizons Documentary Brings Humanity Closer to the Edge of the Solar System
New Horizons is the first mission to the Kuiper Belt, a gigantic zone of icy bodies and mysterious small objects orbiting beyond Neptune. This region also is known as the “third” zone of our solar system, beyond the inner rocky planets and outer gas giants. Johns Hopkins University Applied Physics Laboratory (APL) in Maryland, designed, built and operates the New Horizons spacecraft, and manages the mission for NASA’s Science Mission Directorate in Washington. The Year of Pluto - NASA New Horizons is a one hour documentary which takes on the hard science and gives us answers to how the mission came about and why it matters. Interviews with Dr. James Green, John Spencer, Fran Bagenal, Mark Showalter and others share how New Horizons will answer many questions. New Horizons is part of the New Frontiers Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Stephen Hawking’s 7 Predictions of Earth’s Demise in the Next 200 Years
What will happen to our planet in the next 200 years? The most famous scientist since Albert Einstein, Stephen Hawking, who has made profound and inspiring discoveries, predicted an extremely dark and pessimistic future to the Earth and its inhabitants. Here are some of Hawking’s most terrifying predictions on how and when our world will meet its demise.
Since scientists started toying with genetically engineered viruses to treat human illnesses, they’ve also discovered other possible uses for them. Nowadays, pharmacists are even combining several deadly viruses into a single shot and doing some weird stuff with DNA mixing.
Hawking was a firm believer in extraterrestrial life, and he was convinced that they will eventually invade our planet. And no, unfortunately, they probably won’t come in peace. In his final work, A Smooth Exit from Eternal Inflation, completed just two weeks before he died, Hawking predicted that our universe will eventually fade into darkness as all the stars run out of energy.
Although Hawking's life basically depended on artificial intelligence, he didn't trust it at all. He once said that it might just be “the worst invention in the history of our civilization” because it’ll probably replace humans altogether.
Hawking added that global warming will make the conditions on Earth similar to those on Venus. To save ourselves from problems like overpopulation (and the scarcity of resources that comes with it), pandemics, and pollution, we have to discover new worlds and become a multi-planetary species.

-We still don't fully understand the long-term damage genetically engineered vaccine concoctions might have.
-Chances are that cosmic beings will find our floating rock in space and they’ll most likely want to either destroy us or study us like lab rats.
-Hawking predicted that our universe will eventually fade into darkness as all the stars run out of energy.
-The scientist believed that artificial intelligence could eventually outsmart and outperform humans or, worse, decide to get rid of us.
-The development of militarized technology and weapons of mass destruction could lead us to disastrous consequences, which would mean the end of our world.
-According to Hawking, we have to find another planet to live on within the next 100 years. Otherwise, we’ll die out as a species because Earth has already reached “the point of no return”.
-Global warming will make the conditions on Earth similar to those on Venus. The average temperature will be about 480°F. Our planet will burst into flames in less than 600 years.

| 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.

Finding Life Beyond Earth: Are we Alone - NOVA Documentary HD
Since the beginning of civilization, humanity has wondered whether we are alone in the universe. As NASA has explored our solar system and beyond, it has developed increasingly sophisticated tools to address this fundamental question. Within our solar system, NASA’s missions have searched for signs of both ancient and current life, especially on Mars and soon, Jupiter’s moon Europa. Beyond our solar system, missions, such as Kepler and TESS, are revealing thousands of planets orbiting other stars.
The explosion of knowledge of planets orbiting other stars, called exoplanets, and the results of decades of research on signatures of life - what scientists call biosignatures - have encouraged NASA to address, in a scientifically rigorous way, whether humanity is alone. Beyond searching for evidence of just microbial life, NASA now is exploring ways to search for life advanced enough to create technology.
Technosignatures are signs or signals, which if observed, would allow us to infer the existence of technological life elsewhere in the universe. The best-known techno-signature are radio signals, but there are many others that have not been explored fully.
In April 2018, new interest arose in Congress for NASA to begin supporting the scientific search for technosignatures as part of the agency’s search for life. As part of that effort, the agency is hosting the NASA Technosignatures Workshop in Houston on Sept. 26-28, 2018, with the purpose of assessing the current state of the field, the most promising avenues of research in technosignatures and where investments could be made to advance the science. A major goal is to identify how NASA could best support this endeavor through partnerships with private and philanthropic organizations.
What are Technosignatures?
The term technosignatures has a broader meaning than the historically used “search for extraterrestrial intelligence,” or SETI, which has generally been limited to communication signals. Technosignatures like radio or laser emissions, signs of massive structures or an atmosphere full of pollutants could imply intelligence.
In recent decades, the private and philanthropic sectors have carried out this research. They have used such methods as searching for patterns in low-band radio frequencies using radio telescopes. Indeed, humanity's own radio and television broadcasts have been drifting into space for a number of years. NASA’s SETI program was ended in 1993 after Congress, operating under a budget deficit and decreased political support canceled funding for a high-resolution microwave survey of the skies. Since then, NASA’s efforts have been directed towards furthering our fundamental understanding of life itself, its origins and the habitability of other bodies in our solar system and galaxy.
Where are all the aliens?
Our Sun is just one star among billions in our galaxy. In the last few years, scientists have detected thousands of planets around other stars and it seems that most stars have planetary systems. It’s therefore likely that there will be large numbers of habitable planets in the Milky Way galaxy and beyond that are capable of supporting intelligent life. Some of these intelligent civilizations, if they’re out there, may have even developed interstellar travel.

Can you imagine our world in 2050? Can you imagine the earth in 2050? Can you imagine people in 2050? Do you want to know the future of earth? By mid-century there will likely be 9 billion people on the planet, consuming ever more resources and leading ever more technologically complex lives. What will our cities be like? How will we eat in the future of Earth? Will global warming trigger catastrophic changes, or will we be able to engineer our way out of the world climate crisis?
In the future world demographic changes will certainly be dramatic. Rockefeller University mathematical biologist Joel Cohen says it's likely that by 2050 the majority of the people in the world will live in urban areas of the earth, and will have a significantly higher average age than people today.

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?

A True Story About Planet Pluto
Pluto (minor-planet designation 134340 Pluto) is the largest object in the Kuiper belt, and the tenth-most-massive body observed directly orbiting the Sun. It is the second-most-massive known dwarf planet, after Eris. Like other Kuiper-belt objects, Pluto is composed primarily of rock and ice and is relatively small, approximately one-sixth the mass of the Moon and one-third its volume. It has an eccentric and highly inclined orbit that takes it from 30 to 49 AU (4.4--7.4 billion km) from the Sun. This causes Pluto to periodically come closer to the Sun than Neptune, but an orbital resonance with Neptune prevents the bodies from colliding. In 2014 it was 32.6 AU from the Sun.
Discovered in 1930, Pluto was originally classified as the ninth planet from the Sun. Its status as a major planet fell into question following further study of it and the outer Solar System over the ensuing 75 years. Starting in 1977 with the discovery of the minor planet 2060 Chiron, numerous icy objects similar to Pluto with eccentric orbits were found. The most notable of these was the scattered disc object Eris, discovered in 2005, which is 27% more massive than Pluto. The understanding that Pluto is only one of several large icy bodies in the outer Solar System prompted the International Astronomical Union (IAU) to define formally in 2006 what it means to be a planet. This definition excluded Pluto and reclassified it as a member of the new dwarf planet category (and specifically as a plutoid). A few astronomers hold that Pluto should have remained classified as a planet, and that other dwarf planets and even moons should be added to the roster of planets along with Pluto.
Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Nix, Hydra, Kerberos, and Styx. Pluto and Charon are sometimes described as a binary system because the barycenter of their orbits does not lie within either body. The IAU has yet to formalise a definition for binary dwarf planets, and Charon is officially classified as a moon of Pluto.
On July 14, 2015, the Pluto system is due to be visited by spacecraft for the first time. The New Horizons probe will perform a flyby during which it will attempt to take detailed measurements and images of the Plutoid and its moons.
The Earth is Not Alone | Alien Planet
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.
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.

The History of Earth - How Our Planet Formed - Full Documentary HD
In the very beginning of earth's history, this planet was a giant, red hot, roiling, boiling sea of molten rock - a magma ocean. The heat had been generated by the repeated high speed collisions of much smaller bodies of space rocks that continually clumped together as they collided to form this planet. As the collisions tapered off the earth began to cool, forming a thin crust on its surface. As the cooling continued, water vapor began to escape and condense in the earth's early atmosphere. Clouds formed and storms raged, raining more and more water down on the primitive earth, cooling the surface further until it was flooded with water, forming the seas.
It is theorized that the true age of the earth is about 4.6 billion years old, formed at about the same time as the rest of our solar system. The oldest rocks geologists have been able to find are 3.9 billion years old. Using radiometric dating methods to determine the age of rocks means scientists have to rely on when the rock was initially formed (as in - when its internal minerals first cooled). In the infancy of our home planet the entire earth was molten rock - a magma ocean.
Since we can only measure as far back in time as we had solid rock on this planet, we are limited in how we can measure the real age of the earth. Due to the forces of plate tectonics, our planet is also a very dynamic one; new mountains forming, old ones wearing down, volcanoes melting and reshaping new crust. The continual changing and reshaping of the earth's surface that involves the melting down and reconstructing of old rock has pretty much eliminated most of the original rocks that came with earth when it was newly formed. So the age is a theoretical age.
When Did Life on Earth Begin?
Scientists are still trying to unravel one of the greatest mysteries of earth: When did life first appear and how did it happen? It is estimated that the first life forms on earth were primitive, one-celled creatures that appeared about 3 billion years ago. That's pretty much all there was for about the next two billion years. Then suddenly those single celled organisms began to evolve into multicellular organisms. Then an unprecedented profusion of life in incredibly complex forms began to fill the oceans. Some crawled from the seas and took residence on land, perhaps to escape predators in the ocean. A cascading chain of new and increasingly differentiated forms of life appeared all over the planet, only to be virtually annihilated by an unexplained mass extinction. It would be the first of several mass extinctions in Earth's history.
Scientists have been looking increasingly to space to explain these mass extinctions that have been happening almost like clockwork since the beginning of living time. Perhaps we've been getting periodically belted by more space rocks (ie. asteroids), or the collision of neutron stars happening too close for comfort? Each time a mass extinction occurred, life found a way to come back from the brink. Life has tenaciously clung to this small blue planet for the last three billion years. Scientists are finding new cues as to how life first began on earth in some really interesting places - the deep ocean.
