EXTRATERRESTRIAL LIFE

The SETI Institute's Nathalie Cabrol walks you through what it's like to prepare for a month-long field expedition to the mountains of Chile.

Today, we discuss the possibility of a more idle but settled civilisation: one that remains utterly restricted to the boundaries of their home planet and sees no point whatsoever in traversing the stars, even if they have the ability to do so, as a solution to why we aren't seeing any alien civilisations in the night sky. ►Click here to subscribe: https://www.youtube.com/channel/UCB0fFWQLZ2oj-FaoDUG_wow?sub_confirmation=1 ►Written, Produced & Narrated by David ►Share this video: https://www.youtube.com/watch?v=Uen6euyVYFM Music: “Cylinder Five” by Chris Zabriskie “So Many Stars” by Miguel Johnson “Sirius” by Sergey Cheremisinov Credits: Vidsplay.com

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Discussion of advanced extraterrestrial civilizations often hinges on the idea that they may have ascended to a higher state or higher level of reality, and lost interest in us and the rest of the galaxy. While we can't know what technologies or enlightened paths they might have available, we can ask how realistic the portrayals of those aliens might be, and if this notion make sense as a Fermi Paradox solution.

Does intelligent alien life exist? Answering the question of are we alone has turned out to be a bit more difficult than was originally envisioned when SETI first began decades ago. At first it was a matter of looking for giant omnidirectional beacons blasting out high energy messages, much like what we saw in the movie contact. But as we’ve gone through the process of searching, it’s becoming evident that such a scenario was in a way wishful thinking. We have seen no such unambiguous beacons, and thinking on just why a civilization would expend massive amounts of energy on a signal has changed. It's very likely to be far more subtle than that, and that any intentional message would be beamed directly at us. But beacons aren’t the only game in town. Since the advent of SETI, other technosignatures beyond radio have been thought of. Now we can look for laser emissions, industrial chemicals in the atmospheres of exoplanets, Dyson swarms, and a host of other signatures that would tell us if there are alien civilizations out there. Where is intelligent life in the universe? John is joined with Isaac Arthur to discuss the Fermi paradox, to try and answer where all of the intelligent life is in the universe, and look at what possible techno signatures are most likely. Dyson spheres and Dyson swarms, von neumann probes, and machine civilizations.

Earlier this year, Verge Science went hunting for space dust on a rooftop in Brooklyn. The hunt turned up some promising samples, but looking at them under a microscope led to inconclusive results — even from the world’s foremost micrometeorite hunter. To get to the bottom of things, we took a trip to NASA's Johnson Space Center to learn how to verify suspected space samples and to learn about what these tiny specks could teach us about the secrets of the universe.

People are always worried that alien civilizations will detect the transmissions from our old radio shows and television broadcasts, and send in the invasion fleet. But the reality is that life itself has been broadcasting the existence of life on Earth for 500 million years. Blame it on the plants. In addition to filling the atmosphere with oxygen, plants give off a very specific wavelength visible in infrared radiation. It’s the kind of signal that other civilizations could search for as they’re scanning the galaxy. It’s what we’ll be looking for too. But don’t just blame the plants. Other forms of life have been giving off signals too, signals we can search for as we discover new exoplanets and wonder if they have life there.

Watch Kalind Carpenter and Morgan Cable from JPL present the Exobiology Extant Life Surveyor or EELS robot architecture which is designed to carry the latest instruments into dynamic arenas in search of life. EELS is adaptable to traverse ocean world inspired terrain, fluidized media, enclosed labyrinthian environments and liquids. It is a snake-like self-propelled endoscope form comprising serially-replicated segments with encapsulated locomotion and bending. This lecture was presented at the Keck Institute for Space Studies on July 15, 2019. Speakers' Biography: Kalind Carpenter is a Robotics Engineer in the robotic Vehicles and Manipulators group at JPL. The lab he has helped create focuses on rapid technology development and end effectors specifically tailored to gripping and extreme surface mobility. He is the principal investigator (PI) of the Exobiology Extant Life Surveyor (EELS), a snakelike robot aimed to access Enceladus’s ocean through an active plume. He has collaborated on four patents including two based on his thesis research and has three more provisional patents in place. Dr. Morgan Cable is a Research Scientist at the NASA Jet Propulsion Laboratory in Pasadena, California. She worked on the Cassini Mission as a Project Science Systems Engineer, and is currently a member of the Project Science Team for the Europa Lander mission concept. Morgan’s research focuses on organic and biomarker detection, through both in situ and remote sensing techniques. While earning her Ph.D. in Chemistry at Caltech, she designed receptor sites for the detection of bacterial spores, the toughest form of life. As a NASA Postdoctoral Fellow at JPL, Morgan developed novel protocols to analyze organic molecules such as amines and fatty acids using small, portable microfluidic sensors. Currently Dr. Cable performs laboratory experiments to study the unique organic chemistry of Titan, a moon of Saturn. She and colleagues were the first to discover a co-crystal, the equivalent of a ‘hydrated mineral’, made exclusively of organics that may exist on Titan’s surface. This work has led to the inception of a new field, Titan ‘petrology’. Morgan also conducts field work in extreme environments on Earth, searching for life in places such as the Atacama Desert, the summit of Mt. Kilimanjaro and the lava fields in Iceland.

Thank you to Draper and its Hack the Moon initiative for supporting PBS Digital Studios | Learn more at https://wehackthemoon.com. I got to visit two awesome upcoming NASA missions searching for life in our solar system! The Mars 2020 rover mission targeting the Jezero Crater and the Europa Clipper reconnaissance mission to explore one of Jupiter's moons due to launch in 2023. I explore if alien life is possible, where we're most likely to find it and why. I know, this video is a bit different from most Physics Girl videos. It's part of a PBS miniseries called Stellar, done in collaboration with Matt O’Dowd from @PBSSpacetime and Joe Hanson from @It'sOkayToBeSmart. Over six episodes we travel to telescopes, go inside space research centers, and chat with amazing scientists. Next up is Joe's episode where he explores where life might be outside our solar system.

NASA plans to send an unmanned drone to Titan, Saturn’s largest moon. Titan resembles an early Earth in several ways, containing a thick atmosphere, liquid lakes and rivers on its surface, and an underground ocean of water. So researchers think it might have the ingredients for alien life.

Are we alone in this vast universe? Some think that’s highly unlikely. With new technologies joining the search, NASA estimates we’ll find definitive evidence of aliens within 20 to 30 years. Which raises the vital question: And then what? Will the news inspire jubilation, despair, or fear? Will aliens be seen as gods or interlopers? Evidence of alien life will provoke fundamental questions about our place in the universe–not just about who they are, but also who we are. Join astronomers, astrobiologists, anthropologists, philosophers, and linguists as we ponder these issues.

Could life exist around red dwarf stars? That's one of the most important questions in our search for life in the universe. Red dwarf stars are the most common type of star and they live for up to several trillion years. So if life can exist around red dwarf stars, then life might be very common in the universe. In fact, the two closest planets to the Sun, Proxima Centauri and Barnard's star, each host potentially habitable planets (Proxima b and Barnard b). 🔔 Subscribe for more: https://www.youtube.com/christianready?sub_confirmation=1 🖖 Share this video with a fellow space traveler: https://youtu.be/28YZEmkTvew 🔴 Watch my most recent upload: https://goo.gl/QbRcE2 🚀 Help me improve the channel by joining the community on Patreon https://patreon.com/launchpadastro 🚀 Check out Launch Pad merchandise! https://teespring.com/stores/launchpadastro Disclaimer: Some of these links go to one of my websites and some are affiliate links where I'll earn a small commission if you make a purchase at no additional cost to you. 🐟 From out of town?

If we want to discover alien life out there in the universe, we first need to figure out where to look—and what we're even looking for. Will it be biological like us? Could it be artificial, or take some other form we haven't yet considered? And how do we find something so fundamentally different from ourselves? In this program, scientists devise plans for searching for beings beyond Earth while they grapple with the very definition of life.

Some of these factors include: Special place in the Milky Way It turns out our position in the Milky way might be beneficial as the low star density prevents other stars from messing up our orbits. The right type of star. Our sun is a G2 main sequence star that remains stable for a very long time. Rocky planet in the Goldilocks zone Earth is just the right distance from the sun to form liquid water. Magnetic Shield We're the only rocky planet with a magnetic shield protecting us from solar radiation. Jupiter Jupiter and the outer gas giants protect us from asteroid and comet impacts, and this might be rare in the universe. Tectonic activity We're the only planet with tectonic plates constantly rebuilding the crust.
