New Planets in the Universe Documentary - Exoplanet Exploration: Planets Beyond our Solar System


What Is an Exoplanet Documentary - Exoplanet Exploration Planets Beyond our Solar System

The first exoplanet to burst upon the world stage was 51 Pegasi b, a hot Jupiter 50 light-years away that is locked in a four-day orbit around its star. The watershed year was 1995. All of a sudden, exoplanets were a thing.

But a few hints had already emerged. A planet now known as Tadmor was detected in 1988, though the discovery was withdrawn in 1992. Ten years later, more and better data showed definitively that it was really there after all.

And a system of three pulsar planets also had been detected, beginning in 1992. These planets orbit a pulsar some 2,300 light-years away. Pulsars are the high-density, rapidly spinning corpses of dead stars, raking any planets in orbit around them with searing lances of radiation.

Now we live in a universe of exoplanets. The count of confirmed planets is 3,700, and rising. That’s from only a small sampling of the galaxy as a whole. The count could rise to the tens of thousands within a decade, as we increase the number, and observing power, of robotic telescopes lofted into space.

Exploring Planets Outside the Solar System Documentary - In Search of Alien Planets in the Universe

Scientists already know about a vast number of exoplanets, or worlds beyond our solar system: telescopes have helped us catalogue thousands already, with many more to come. But it is far more difficult to know what conditions might be like on those planets, since they are so different.

In order to narrow that down, the researchers behind the new study combined a variety of data to understand how habitable planets around M dwarf stars – which make up 70 per cent of those in our galaxy – might be. Planets around M dwarf stars are thought to be the most likely place for us to find alien life, because they are so common and therefore easier to find.

The study helped them redefine our understanding of whether a planet could be habitable, adding new questions to be asked of planets by taking into account the radiation coming from a star and how the planets rotate.

Weird Alien Worlds Beyond Our Solar System(full documentary)HD

Have you ever wondered about planets in other solar systems? Have you ever thought about the possibility of life elsewhere in the Universe? For the first time in human history, we know that planets around other stars not only exist, but are common.

Alien Worlds focuses on the search and characterization of planets orbiting other stars (called extrasolar planets or “exoplanets”). Over the course of nine modules, we will learn some of the techniques used to discover the thousands of known exoplanets and will discuss how we can use basic scientific tools to characterize the sizes, masses, compositions, and atmospheres of exoplanets. We will also learn about the diversity of stars in the Galaxy to understand how stellar properties affect exoplanet detection techniques and influence planetary formation and habitability.

Exoplanets - Planets beyond our Solar System

One of the most exciting developments in Astronomy over the last few years has been the discovery of “extra-solar planets” or exoplanets; i.e., planets around other stars in our galaxy. Numerous exoplanets have been discovered through various techniques; they vary from objects much bigger than Jupiter down to Earth-size bodies. A combination of four videos, courtesy of ESA:

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.

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.

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.

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.

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.

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.

ANOTHER EARTH: Alien Planet - Space Documentary HD

We Are Not Alone In The Universe
I cannot imagine any single discovery that would have more impact on humanity than the discovery of life outside of our solar system. There is a human-centric, Earth-centric view of life that permeates most cultural and societal thinking. Finding that there are multiple, perhaps millions of origins of life and that life is ubiquitous throughout the universe will profoundly affect every human.

We live on a microbial planet. There are one million microbial cells per cubic centimeter of water in our oceans, lakes and rivers; deep within the Earth's crust and throughout our atmosphere. We have more than 100 trillion microbes on and in each of us. The Earth's diversity of life would have seemed like science fiction to our ancestors. We have microbes that can withstand millions of Rads of ionizing radiation; such strong acid or base that it would dissolve our skin; microbes that grow in ice and microbes that grow and thrive at temperatures exceeding 100 degrees C. We have life that lives on carbon dioxide, on methane, on sulfur, or on sugar. We have sent trillions of bacteria into space over the last few billion years and we have exchanged material with Mars on a constant basis, so it would be very surprising if we do not find evidence of microbial life in our solar system, particularly on Mars.

The recent discoveries by Dimitar Sasselov and colleagues of numerous Earth and super-Earth-like planets outside our solar system, including water worlds, greatly increases the probability of finding life. Sasselov estimates approximately 100,000 Earth and super-Earths within our own galaxy. The universe is young so wherever we find microbial life there will be intelligent life in the future.

Expanding our scientific reach further into the skies will change us forever.

NASA Has Just Discovered a New Planet!

If you've always been interested in outer space, here's news for you: astronomers have recently found a potentially habitable planet! It's called Barnard’s Star B. It has slightly more than 24 hours in a day, and it’s always sunny there no matter what. Actually, it's really cold there, but simple lifeforms can develop and survive in these conditions!

- Look up high into the dark sky, and you’ll see a little murky-looking circle. No, that’s not Barnard’s moon – it’s the planet’s sun. Now look down. Deep under your feet lie countless rivers, lakes, and seas of liquid methane.
- Barnard’s sun is only located 6 light-years away from us, and it’s the 4th closest star to our solar system. Try to imagine our sun 5 times smaller and much less bright.
- Though Edward Emerson Barnard wasn’t the first to discover this star, he proved in 1916 that it’s the fastest star known to us.
- Barnard’s Star is what astronomers call a red dwarf – a small, dim, and truly ancient star that’s getting pretty close to the end of its life cycle.
- The first person to assume there was a planet somewhere near this star was astronomer Peter van de Kamp. Back in the 60s, he observed “wobbles” in the star’s movement.
- Astronomers took lots of measurements with the most advanced astronomical equipment you could imagine, and they came out with 99% certainty that the planet Barnard’s Star B exists.
- “Super-earth” is just the term astronomers use to describe only the size of a planet that’s larger than Earth but considerably smaller than ice giants like Neptune.
- This planet is a huge ball of rock and ice that lies beyond the habitable zone of its star. Even though it’s closer to Barnard’s Star than our Earth is to the Sun, its star provides only 3% of the light that our Sun does.
- According to a 2015 study at Cornell University, chances are that simple methane-based lifeforms can develop and survive in these conditions.
- The existence of such lifeforms is pure theory. So the idea that this newly found Barnard’s Star B planet is habitable for us humans is really far-fetched for now.

Strange planets and Possible life in other planets Documentary - Explore The Amazing Universe

Strange New Worlds provides an insider's look at the cutting-edge science of today's planet hunters, our prospects for discovering alien life, and the debates and controversies at the forefront of extrasolar-planet research. -- In Strange New Worlds, renowned astronomer Ray Jayawardhana brings news from the front lines of the epic quest to find planets--and alien life--beyond our solar system. Only in the past two decades, after millennia of speculation, have astronomers begun to discover planets around other stars--thousands in fact. Now they are closer than ever to unraveling distant twins of the Earth. In this book, Jayawardhana vividly recounts the stories of the scientists and the remarkable breakthroughs that have ushered in this extraordinary age of exploration. He describes the latest findings, including his own, that are challenging our view of the cosmos and casting new light on the origins and evolution of planets and planetary systems. He reveals how technology is rapidly advancing to support direct observations of Jupiter-like gas giants and super-Earths--rocky planets with several times the mass of our own planet--and how astronomers use biomarkers to seek possible life on other worlds.

Alien Planets The Search for Habitable Planets - Exploration of the Planets in Solar System

There is only one planet we know of, so far, that is drenched with life. That planet is Earth, as you may have guessed, and it has all the right conditions for critters to thrive on its surface. Do other planets beyond our solar system, called exoplanets, also host life forms?

Astronomers still don’t know the answer, but they search for potentially habitable planets using a handful of criteria. Ideally, they want to find planets just like Earth, since we know without a doubt that life took root here. The hunt is on for planets about the size of Earth that orbit at just the right distance from their star – in a region termed the habitable zone.

NASA’s Kepler mission is helping scientists in the quest to find these worlds, sometimes called Goldilocks planets after the fairy tale because they orbit where conditions are just right for life. Kepler and other telescopes have confirmed a handful so far, all of which are a bit larger than Earth — the Super Earths. The search for Earth’s twin, a habitable-zone planet as small as Earth, is ongoing.

What Lies Beyond the Edge of Our Solar System?

The Voyager space probes have gone further into the unknown than any other spacecraft. With both probes officially in interstellar space, what have we learned?

In 1965, a PhD student figured out that every 176 years the four planets in our solar system align in such a unique way that it is possible to use their gravitational forces to slingshot from one planet to the next.

This insight, that came to fruition using just a slide rule and simple computer programs, became part of an ambitious mission to send two probes and golden records out into space for a grand tour.

Enter: The Voyagers.

The Voyager probes are two obscure looking robots, weighing roughly 800 kilograms with giant arms and big ears, it took 1,500 engineers and scientists to bring these robotic explorers to life.

The Voyagers took some of the first detailed snapshots of planets and moons—revealing Io’s volcanism, close-up details of Saturn’s icy rings, and Neptune’s great dark spot.

And after traveling for more than 43 years, clocking in 18 billion kilometers traveled, the Voyagers are taking humanity into the next great beyond: interstellar space.

With the opportunity to visit Uranus and Neptune, the NASA engineers developed a mission within a mission, outfitting the probes with 11 different instruments, redundant systems, and autonomous controls.

Find out more about the Voyager mission, what we’ve learned so far, and the experts behind it all on this episode of Focal Point.

The Search for Alien Planets and Life beyond Our Solar System Documentary

The Milky Way has around 100 billion (1011) star systems that could conceivably host intelligent life under our current assumptions. An estimate of 100,000 (105) active civilizations in the galaxy would mean one per million star systems. At the exponential rate of growth in signal processing, researchers will have examined one million candidates by around 2034, bringing the odds of a discovery into the probable. Adding or removing a zero from the estimate of the number of civilizations out there merely adds or subtracts six years from the estimate, respectively, since that’s how long it takes to expand our search proportionally. See you in 2040, aliens.
