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?

NASA reports seeing the 1st confirmed alien object to enter Earth's solar system

NASA: Scientists were surprised and delighted to detect --for the first time-- an interstellar asteroid passing through our solar system. Additional observations brought more surprises: the object is cigar-shaped with a somewhat reddish hue. The asteroid, named ‘Oumuamua by its discoverers, is up to one-quarter mile (400 meters) long and highly-elongated—perhaps 10 times as long as it is wide. That is unlike any asteroid or comet observed in our solar system to date, and may provide new clues into how other solar systems formed.

Astrobiology and the Search for Extraterrestrial Life - with Ian Crawford

What can modern results in astrobiology tell us about the prospects for finding intelligent life elsewhere in the Universe?
Subscribe for regular science videos:

The famous Drake equation, which provides a rough estimate of the number of civilisations in our galaxy, predicts that space should be teaming with aliens. So where are they and why have we not found them yet?

Watch the Q&A here:

Ian Andrew Crawford is professor of planetary science and astrobiology at Birkbeck, University of London. Crawford is a specialist in the science and exploration of the Moon and in the search for life in the Universe. Before switching his research interests to planetary science in 2003, Crawford had a 15-year career at University College London as an observational astronomer specialising in studies of the interstellar medium. He is the author of over 130 peer-reviewed research papers in the fields of astronomy, planetary science, astrobiology and space exploration. Crawford is a Fellow, and currently Vice President, of the Royal Astronomical Society, and a former member of the European Space Sciences Committee (ESSC) of the European Science Foundation. In 2014 he was appointed to the European Space Agency's Human Spaceflight and Exploration Science Advisory Committee (HESAC).

Why NASA stopped funding the search for intelligent aliens

The SETI Institute uses large radio telescopes to scan the universe for signals of intelligent alien life. Although the organization has existed for decades, it still has yet to find anything that proves we are indeed not alone.

However, SETI senior astronomer Seth Shostak believes the search has been hampered by a lack of funding for the work the organization does. He thinks that increased funding could lead to a discovery that proves extraterrestrial life is really out there.

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?

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.

Are There Other Earths?

What are the odds of life on planets orbiting nearby stars? Scientists, wielding sensitive new telescopes and big data tools, have detected planets around thousands of stars; some Sun-like and some very different from our star. Many newly discovered exoplanets lie in habitable zones, where liquid water may support the chemistry that enables biology. How will astronomers discover if we have company in the cosmos...and where they live?

Universe: Beyond the Millennium - Alien Life

Universe: Beyond the Millennium is a television series observing astronomical phenomena, research, and theories on the universe and its origins.

Narrated by John Hurt.

The documentary premiered in 1999 and presents an overview of the universe as humans understood it at that time, and how we think it will evolve in the next millennium. Using 3D computer generated graphics, the series features animated sequences that offer insight into the Big Bang theory and the anatomy of the sun.

Alien Life, when NASA scientists found a lump of rock from Mars with microscopic fossils in it, the search for extraterrestrial life beyond our own became a credible objective. Researchers and scientists from SETI (Search for Extra-Terrestrial Intelligence) have spent decades trying to determine how an alien life force would contact us and if one does, how we would reply.

At the start of a new millennium we're about to embark on the greatest adventure of all time. Five hundred million miles from Earth, a spacecraft will land on Jupiter's icy moon, Europa. It's mission, to search for alien life. As we reach out across the galaxy, our spacecraft will explore the most extreme environments to answer the ultimate question, are we alone?

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.

Searching For Alien Life in the Hot Springs of Nevada

For astrobiologist Luke McKay, the question of whether life exists on other planets begins at the microbial communities thriving in America’s hot springs. It’s at hostile environments like these where extremophiles, to the bewilderment of scientists, are able to survive on our planet where all other life can’t.

“What I do is, I go to these extreme environments and I look at microbial relatives of ancient life. The early Earth did not have oxygen—we’re talking four billion years ago, when life developed on Earth,” explains McKay. In episode four of The Most Unknown, psychologist Axel Cleeremans joins Luke McKay to search for Earth analogues of probable extraterrestrial life at Nevada’s Great Boiling Spring.
