Is Alien ‘Life’ Weirder Than We Imagine: Who Is Out There?

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.

PARTICIPANTS: Lisa Kaltenegger, Caleb Scharf, Susan Schneider, Sara Walker

MODERATOR: Nicole Stott

Paul Horowitz: "The Search for Extraterrestrial Intelligence" | Talks at Google

Paul Horowitz visited Google's office in Cambridge, MA to discuss the SETI (Search for Extraterrestrial Intelligence) project at Harvard University.

Establishing an electromagnetic communications link across a thousand light-years presents unique technological challenges. In his talk, Prof. Horowitz visits some highlights of the science and technology of SETI -- Do THEY exist? Is communication possible? What is the best way? Is this just completely insane? -- and describes interesting searches his project and others have been doing.

Paul Horowitz is a Research Professor of Physics and of Electrical Engineering at Harvard, and is co-author of The Art of Electronics.

SETI at Harvard was supported in part by grants from NASA, The Planetary Society, and the Bosack/Kruger Charitable Foundation.

How are we looking and listening for intelligent life?

↓↓↓ More info and sources below ↓↓↓

Now that we know planets are common in our galaxy, how would we tell if one holds life? Sure, it will take incredibly powerful telescopes and ambitious new space missions, but what are we looking for? What are we listening for? How do we help other worlds know that we are here?

Here's the thing: Life on Earth has an expiration date. No matter what humans do, our aging sun will eventually be so hot that we can't survive. If we want to live on, it will have to be beyond Earth. The only question is, will it be US who live on, or just our radio broadcasts and dead satellites?

Alien Contact: What Happens Next?

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.

Meet The Father of the Search for Extraterrestrial Intelligence

Scientists are leaping exponentially closer to finding life beyond Earth. Missions to Mars and Saturn’s moons are prime candidates for finding the first signs of life and NASA can now identify more than 3,500 planets outside our solar system, many with habitable temperatures. That number is quickly growing as space travel technology improves and probes head deeper into the galaxy. Nuclear physicist Taylor Wilson explores one of our civilization's most perplexing questions: Are we alone?

The Search for Primitive and Intelligent Life on Other Planets

Professor Abraham (Avi) Loeb, chair of the Astronomy department, Harvard University.
Are we alone? Probably not, out of modesty - keeping in mind that about a quarter of all stars host a habitable Earth-size planet. Upcoming searches for primitive life will aim to detect oxygen or methane in the atmospheres of transiting planets. Searches for intelligent life will aim to detect artificial signals in the radio or optical bands, as well as artifacts such as megastructures, solar cells that are used to re-distribute light and heat on tidally-locked planets, industrial pollution or artificial light beams. Our own civilization is starting to study the feasibility of interstellar travel using a powerful laser beam pushing on a lightweight sail, the so-called Starshot Initiative. If successful, we might receive a signal from outer space stating: welcome to the interstellar club!.

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.

Alien Technology

Is there anyone out there? Does the popular movie quote ‘ET phone home’ have any substance? Astronomers have been pointing their radio telescopes at the skies for decades trying to pick up alien signals, so far without success. But now there’s a new way of looking for aliens. Hitch a ride with Dr Graham Philips as he joins astronomers trawling through the galaxy looking for signs of extraterrestrial intelligence. #ABCcatalyst

Finding Life Beyond Earth - Is Anybody Out There? - Space Discovery Documentary

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 Search For Life Beyond Earth

For half a century, researchers have been scanning the sky for signs of extraterrestrial intelligence, so far to no avail. But with regular discoveries of new planets around distant stars, the universe seems to be more friendly to life by the day.

Interviews with Jill Tarter and Laurance Doyle from SETI Institute, and Andrew Siemion from UC Berkeley SETI Research Center, also affiliated with SETI Institute.
