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.

Tunguska. A region around which many theories and stories entwine. Did aliens try to land here? Did a meteorite crash? Was there a volcanic eruption? And why is there no crater? There are many theories, but also an answer that could answer all questions. Or maybe not? At 7:14 am on 30 June 1908, the largest explosion recorded in human history to date reverberated throughout our planet. The force of the explosion was two thousand times that of the Hiroshima bomb. A woodland area the size of Luxembourg was eradicated in the Siberian taiga. This incident is recorded in history books as the Tunguska catastrophe. To this day, internationally renowned scientists of various disciplines argue about the causes of this disastrous explosion. The documentary discusses the latest and most controversial insights of these leading scientists. It identifies the reasons why Tunguska has evolved into a phenomenon and points out the curious results produced by this mythical event in culture and economy. #bigbangtunguska #fulldocumentary #space ---- This channel offers you full episodes of high quality documentaries.

Quasars are the brightest phenomenon in the entire universe, able to outshine any type of star, and even entire galaxies containing hundreds of billions of them. Quasars are the product of monster black holes at the centres of large galaxies, and so when we find multi-billion light year clusters of quasars dotted around the early universe, we are forced to reconsider some of our fundamental assumptions of cosmology.

65 million years ago, dinosaurs were wiped out by a gigantic asteroid. We could soon be next. We don’t know when it will happen or where the asteroid will strike. We only know that it will happen — sometime — perhaps in 1,000 years or perhaps tomorrow. Will it be the end of mankind? Through the eyes of a young astronomer, we experience this catastrophic event. On discovering the asteroid on collision course with Earth, he tries to give a warning, but in vain. He survives, but this is just the beginning. The impact results in an eclipse of the sun leading to a global winter and the extinction of many life forms. This drama documentary will depict the scientific background to the catastrophe, with all its consequences for our planet. This is the end of an era, but also the beginning of a new one — the age of the conquerors. Sixty-five million years ago, a comet hit the earth, putting an end to life as it then was. Now a comet is about to hit the earth again. In the dramatised part of this episode, Fernando Martinez, a Mexican who works in Houston, Texas, sets off home to be with his family, the Vaton family in France seeks shelter, and the Baka pygmy tribesmen continue to hunt, unaware of the impending disaster. Astrophysicist Noah Boyle, and computer scientist Shiang Yatan, remain at the observation centre in Hawaii to try to find out exactly when the comet will hit. An asteroid hits the earth in the Mexican province of Yucatan in 2007. The impact causes the entire planet to burst into flames. Humankind is catapulted into a very dark age and this re-enacted docu-drama describes what happens 5, 10, 30, 60 and 80 days and lastly 4 months after the impact. Most life is extinguished within hundreds of kilometres of the crater. The entire earth sinks into darkness. Paris, New York, Hawaii are all in complete darkness and all plant life dies out as a result of the lack of sunlight. Temperatures fall much below anything ever experienced before. Many survivors are left absolutely alone and must fend for themselves. #SuperComet #Space #Documentary ---- This channel offers you full episodes of high quality documentaries.

The summit of Mauna Kea is perfect for astronomy but it's also regarded as one of the most sacred lands for Native Hawaiians. We get a look inside the two sides that have been debating about the construction of one of the largest ground telescopes in the world. » Subscribe to Seeker! http://bit.ly/subscribeseeker » Visit our shop at http://shop.seeker.com Thumbnail Credit: Courtesy TMT International Observatory On the island of Hawaii sits a dormant volcano named Mauna Kea. It’s the highest point in Hawaii, and if you measure from the sea floor, it’s the tallest mountain in the world. And this height, paired with a few other important elements, has made it home to numerous observatories. But, this mountain isn’t just a perfect place to peer deep into the vastness of our universe. It’s also a very sacred place for the local native Hawaiian people, who have been protesting the construction of a newly planned telescope since the site was selected for construction in 2009. This film, from co-directors Carter Lau and Duncan Heger as well as their team from Chapman University, looks to shed light on an important debate that may have been tragically overlooked so many times in the past; science vs culture. This is Beyond the Mauna. #documentary #seekerindie #seeker #nature #conservation ____________________ Seeker empowers the curious to understand the science shaping our world.

An exploration of the Wow! Signal, picked up at the Big Ear radio telescope in 1977. This signal remains unexplained to this day, and represents the best candidate we've ever detected of a signal of intelligent alien origin. Dr. Robert Dixon directed the Ohio State SETI program at the Big Ear Radio Telescope from 1973 to 1997, which was the world's first full-time search for signs of extraterrestrial life from radio signals using a large radio telescope. In 1977 he was one of the first people to be shown the Wow! Signal by discoverer Jerry Ehman. The Wow! Signal with Discoverer Dr. Jerry Ehman https://youtu.be/x67K-Vq1KWk The Mystery of the Wow!

A new type of rocket thruster that could take humankind to Mars and beyond has been proposed by Fatima Ebrahimi a physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). The Plasma thruster would apply magnetic fields to cause particles of plasma, electrically charged gas also known as the fourth state of matter, to shoot out the back of a rocket and, because of the conservation of momentum, propel the craft forward. Current space-proven plasma thrusters use electric fields to propel the particles. The new concept would accelerate the particles using magnetic reconnection, a process found throughout the universe, including the surface of the sun, in which magnetic field lines converge, suddenly separate, and then join together again, producing lots of energy. Reconnection also occurs inside doughnut-shaped fusion devices known as tokamaks. The above text is from: New concept for rocket thruster exploits the mechanism behind solar flares https://www.pppl.gov/news/2021/01/new-concept-rocket-thruster-exploits-mechanism-behind-solar-flares Fatima Ebrahimi is a Principal Research Physicist at the PPPL Theory Department and an Affiliated Research Scholar at the Department of Astrophysical Sciences, Princeton University. Dr. Ebrahimi received her Ph.D. in Plasma Physics from the University of Wisconsin-Madison in 2003. Her research interests span from magnetically confined fusion plasmas to flow-driven plasmas, such as accretion disks. Her primary research experience has been in the field of theoretical and global-computational extended magnetohydrodynamics (MHD), with wide applications to astrophysical, laboratory and fusion plasmas. Also discussed is the ITER project, the international nuclear fusion research project to build a Tokamak reactor. Can we use fusion to create energy on earth? Want to support the channel?

Follow along as NASA launches the Mars 2020 Mission, perhaps the most ambitious hunt yet for signs of ancient life on Mars. The spacecraft will blaze into the Martian atmosphere at some 12,000 miles per hour and attempt to lower the Perseverance Rover in the rocky Jezero Crater, home to a dried-up river delta scientists think could have harbored life. Perseverance will comb the area for signs of life and collect samples for possible return to Earth. Traveling onboard is a four-pound helicopter that will conduct a series of test flights—the first on another planet. During its journey, Perseverance will also test technology designed to produce oxygen from the Martian atmosphere, in hopes that the gas could be used for fuel—or for humans to breathe—on future missions. © 2020 WGBH Educational Foundation All rights reserved This program was produced by GBH, which is solely responsible for its content.
