Over four decades have passed since researchers discovered two continent-sized blobs wrapped around Earth's core, and they're still trying to figure out what they are. Here's what they know so far. There’s a Subterranean Biosphere Hiding in the Earth’s Crust and It’s MASSIVE - https://youtu.be/9h7DSJVeSG8 Read More: The Unsolved Mystery of the Earth Blobs https://eos.org/features/the-unsolved-mystery-of-the-earth-blobs "Part of the reason for this mystery is what Earth scientists have always struggled with: They will never be able to visit the inside of Earth. “We know less about what’s deep below our feet than the surface of the Sun or the Moon or Mars,” said University College London researcher Paula Koelemeijer. Scientists are constantly trying to come up with new ways to peek inside Earth indirectly" Continent-sized anomalous zones with low seismic velocity at the base of Earth's mantle https://www.nature.com/articles/ngeo2733 "However, the origin and composition of the anomalous provinces is uncertain. These zones have long been depicted as warmer-than-average mantle materials related to convective upwelling. Yet, they may also be chemically distinct from the surrounding mantle, and potentially partly composed of subducted or primordial material, and have therefore been termed thermochemical piles. " Origin of the LLSVPs at the base of the mantle is a consequence of plate tectonics – A petrological and geochemical perspective https://www.sciencedirect.com/science/article/pii/S1674987118300847 "In studying the petrogenesis of intra-plate ocean island basalts (OIB) associated with hotspots or mantle plumes, we hypothesized that the two large-low-shear-wave-velocity provinces (LLSVPs) at the base of the mantle beneath the Pacific (Jason) and Africa (Tuzo) are piles of subducted ocean crust (SOC) accumulated over Earth's history. This hypothesis was formulated using petrology, geochemistry and mineral physics in the context of plate tectonics and mantle circulation.

Of all the planets NASA has explored, none have matched the dynamic complexity of our own. Earth is a very special place. From the vantage point of space, the perspective of sky and sea, and all across the land, we study our planet not only to learn about it, but also to protect it.

Carl Sagan's book "Pale Blue Dot" (1994) was inspired by an image taken by Voyager 1, on Feb 14, 1990. The Earth is shown from a distance of about 6 billion km. Voyager 1, on completion of its primary mission, was leaving the solar system, when on Dr. Sagan's request NASA made Voyager turn around its camera one last time to take a photo of Earth across a great expanse of space. The video accompanying words spoken by Dr. Sagan, and written almost 25 years ago are still relevant today, and will perhaps remain so till eternity. As the world marks Earth Day today, there could no better time to ponder on why we, the human species, must overcome our egos, greed, and prejudices to work towards building a more sustainable planet. And preserve and cherish the "Pale Blue Dot", the only home we have ever known. Video Courtesy: carlsagandotcom #EarthDay

This visualization shows a variety of data from the oceans and ice to help explain why Jakobshavn glacier grew thicker and advanced between 2016 and 2017. Initially, the average flow of ice across the Greenland Ice Sheet in these years is shown as colored flow arrows, with blue shades indicating slower movement and red indicating faster. As we draw near we see a large bay named Disko Bay located just to the west of the narrow inlet, or fjord, that is home to Jakobshavn glacier. The water is cut away to reveal the historical temperature of the bay, to a depth of about 400 meters. Around Greenland, water below 150 m depth tends to be warmer than water near the surface. The change in temperature between 1952 and 2017 is shown using blue tones for colder water and red tones for warmer. The deep water warms through most of the 1990s, but cools dramatically after 2015. The ocean temperature changes are shown a second time, with a brief pause on 1979 to see the initial cooler water temperature, 2000 to view the warming and 2017 to view the current cooling trend. Jakobshavn Glacier is Greenland's largest and fastest moving glacier. Over the last 20 years, it has retreated, sped up and thinned. The data shown here reveal that Jakobshavn’s retreat has reversed. Between 2016 and 2018, the glacier advanced and got thicker. Scientists from NASA’s Jet Propulsion Laboratory have linked these changes to cooling of the ocean waters that reach Jakobshavn after traveling around the southern tip of Greenland and reaching into Disko Bay (**Link to publication here**). The ocean cooling was likely related to the natural cycles of warming and cooling that happen in the Atlantic as part of the North Atlantic Oscillation. The strong influence of the ocean on the ice loss from Jakboshavn is somewhat surprising because the role of the ocean has been unclear since the glacier’s floating extension, called an ice tongue, disintegrated in 2003. These results mean that future projections of sea level rise will need to account for the ocean changes in order to accurately predict how fast Greenland’s ice will melt in a warming climate. The visualization pulls out to show the entire Greenland Ice Sheet while ocean is drained to reveal the shape and depth of the ocean floor around the ice sheet. Data from the ECCO ocean circulation model shows ocean currents carrying water around the southern tip of Greenland and up the west coast, where it eventually enters Disko Bay and reaches Jakboshavn glacier. When we zoom in to the Jakobshavn glacier again, we see the glacier is blanketed by more than 40, 000 radar observations. These data show the change in elevation between 2016 and 2017 as measured by an aircraft. These elevation changes are colored so that blue colors indicate an rise in the elevation and orange/red colors indicate a fall. The deepest blue color reflects the advance of the glacier from the 2016 front, appearing in the video as a shaded cliff, to its more advanced location in 2017. Farther downstream in the fjord the patches of blue and red show icebergs, which have detached from the front.

With the estimated sheer size of the universe, it's very likely that a planet with near-identical features to our own could exist somewhere. In the last two decades, we have discovered a huge number of Earth-like planets within merely a few thousand light years of us, let alone within the entire expanse of the universe. As such, humanity has been looking to find the first planet worthy of acting as the second natural human colony.

I've been working on this video for the best part of a month in the background while I've waited for my new laptop to arrive. A couple of weeks ago what I now understand to be a hard drive malfunction caused my laptop to completely die, with no way to recover it. I still may be able to recover some files in the future, but until that time I simply had to start again with my entire video portfolio - and this is my first project. I have been away from YouTube for some time now and have finally got my motivation back, given how long I had to wait. So expect some more videos, and some shorter ones, coming in the next few weeks. I've been quite sick recently, but I'm on the mend now and I hope to get back to my best soon. Thanks for those who stuck by and waited, you're all awesome- and I hope this was enough to act as the first part of an apology! - Popular Playlists! - • Creepy Playlist: https://goo.gl/Gxoqyy • Out of this World: https://goo.gl/AV9ePP • Conspiracy Cases: https://goo.gl/mqmF6P • G-News: https://goo.gl/17K9yu - Out of this World - • The Fermi Paradox: https://youtu.be/lFypvFYO7LQ • The Cold Spot: https://youtu.be/PQHhLHh_8go • Bootes Void: https://youtu.be/SPtSBLpyBu4 - Conspiracy Cases - • 11B-X-1371 Mystery: https://youtu.be/FK314DWnPGs • Dyatlov Pass Incident: https://youtu.be/zkdAUESx7Vk • Denver Airport Conspiracy: https://youtu.be/mUKHMGDe6-w - GD - • G-NEWS: https://goo.gl/17K9yu • "The Best Of" Lists: https://goo.gl/412EaD • Community Commentary: https://goo.gl/tgJvPv • Full GD Playlist: https://goo.gl/dWkXfo - Maps From Hell Series - • Bloodlust Episode: https://youtu.be/W1D2Dxvi0cg • Yatagarasu Episode: https://youtu.be/mmi8db-JV2E • Plasma Pulse Series Episode: https://youtu.be/-plAW84qvB4

In December of 1968, the crew of Apollo 8 became the first people to leave our home planet and travel to another body in space. But as crew members Frank Borman, James Lovell, and William Anders all later recalled, the most important thing they discovered was Earth. Using photo mosaics and elevation data from Lunar Reconnaissance Orbiter (LRO), this video commemorates Apollo 8's historic flight by recreating the moment when the crew first saw and photographed the Earth rising from behind the Moon. Narrator Andrew Chaikin, author of "A Man on the Moon," sets the scene for a three-minute visualization of the view from both inside and outside the spacecraft accompanied by the onboard audio of the astronauts.

The most recent trends in sea level rise mean the low-lying Camargue region of southern France could be submerged by the sea by the end of the century. The sea walls built along the coast in the 1980s have already been broken by the waves, as a combination of rising waters, slowly sinking landmass, and reduced amounts of sediment from the Rhone river spell trouble for this environment. Anis Guelmami uses Copernicus Sentinel satellites to study wetlands like the Camargue, and he tells us the latest news from space.

Description: At the center of the Earth, matter is crushed under pressures millions of times higher than we experience here on the surface. Pressures in the cores of stars and giant planets are even more extreme. To understand how the Earth, Jupiter, and even larger planets outside our solar system came to be, we need to understand the behavior of materials in these extreme conditions. Here at SLAC, we have found ways to push matter to these tremendous temperatures and pressures, if only for very short periods of time. This lecture will describe some of the surprising and even bizarre states of matter we can now create in the laboratory. About the Speaker: Emma McBride is a Panofsky Fellow in SLAC’s High Energy Density Science Division. She received her PhD in 2014 from the University of Edinburgh, where she investigated how high pressure can cause simple metals to behave in unexpected ways. She spent two years at the DESY laboratory in Hamburg, Germany, as a postdoctoral researcher, and then came to SLAC as a Peter Paul Ewald fellow. She has developed dynamic shock compression techniques that can drive solids to extreme pressures, as well as methods for analyzing these massively crushed materials using X-ray lasers at DESY and SLAC.

How widespread within NASA is the conviction that human activity is responsible for climate change? Michelle Thaller knows. She has worked with hundreds of Earth scientists at NASA who study the climate. It's important to note that NASA is an apolitical organization devoted to science, not policy solutions. Read more at BigThink.com: https://bigthink.com/videos/does-nasa-have-any-climate-change-skeptics Follow Big Think here: YouTube: http://goo.gl/CPTsV5 Facebook: https://www.facebook.com/BigThinkdotcom Twitter: https://twitter.com/bigthink Hi Jay. So your question is how widespread is it within NASA that scientists are convinced that human activity is responsible for climate change? And this is something that is important to say very, very clearly. I have known and worked with hundreds of earth scientists at many different locations in NASA, all of them, all of them believe that human activity is responsible for the current climate change that we see going so fast it's almost unprecedented. I want you to think about that. One thing that I take really seriously and I'm very proud of is that NASA is not a political organization. We are scientists that work for the American people. We're funded by taxpayer's money. And what we do is we make measurements. We have many, many different satellites that are orbiting the earth right now they're looking at things like ice on the oceans and at the poles, they're looking for things like vegetation growth and the change of that, ocean level, is the ocean level rising? Yeah it turns out that it is. So we have many scientists all over the planet studying all of the different ramifications of climate change. We understand the causes. There actually is no scientific controversy about that. Humans are releasing greenhouse gases into the atmosphere and this is warming our planet. Now what scientists are researching currently, and they don't all agree about, is what are the most important components of driving climate change. Is it carbon dioxide? Could it be something else like methane? When methane gets released that's an even more powerful greenhouse gas. We don't agree on how quickly things like the ocean level will rise. People have different estimates for how quickly that will happen. So there still is scientific controversy about what the most important aspects of climate change are and how quickly it will go in the future, but there is no scientific disagreement within NASA that humans are causing climate change. Now I started this off by saying that one of the things I'm very proud of is that NASA is not political. And what that means for me is that I cannot advocate for any specific solution to climate change. That's not my job. That's up to policymakers. People might suggest things like having more solar energy or cutting carbon emissions or things like that, but at NASA we really understand that's not us, that's up to the American people, our leaders and leaders around the world. What we do is provide the facts to everybody on the planet. All of our data is actually free to any government, any person, any scientist all over the world that wants to use it. So we all know what's causing climate change, we can't tell you what to do about it but we can say it's time to do something about it.

Are we alone? How unique is our Earth? Should the hunt for life beyond Earth uncover a multitude of habitable worlds and few (if any) inhabited ones, humanity would begin to understand just how lonely and fragile our situation is. On the other hand, if our hunt yields a true diversity of inhabited worlds, then we would learn something fundamental about the commonality of life in the cosmos. Like this content?
