Searching for Alien Life on other Earth - Will We Find Extraterrestrial Life in the Universe

x

Are We Alone? The Search for Life in the Universe

The SETI Institute is bringing SETI Talks to San Francisco for the first time, thanks to a partnership with U.C. Berkeley Extension. Three scientists will discuss their individual approaches to answering the question, “are we alone?” and how they are searching for life elsewhere in the universe. Will we find a so-called technosignature, evidence of advanced technological civilizations? Should we explore places in our solar system with liquid water, such as Europa or Enceladus, for microbial life? And what can the study of exoplanets tell us about the possibility of extraterrestrial life? What are the near-term chances of discovering some form of life elsewhere?

NASA: Proof of alien life closer

They may not be Star Trek-type extraterrestrials, but we may be close to finding evidence of alien life, a NASA scientist says.

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.

Bizarre Alien Life Forms | Known Universe: Alien Contact


National Geographic

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.

Aliens, exoplanets and the search for extraterrestrial intelligence

Forget little green men, what would alien intelligence look like if we found it outside our Solar System? Claire Reilly takes a look at SETI, the Search for Extra Terrestrial Intelligence, and how science is actually not that far away from science fiction.

Astronomer Explains How SETI Searches for Aliens | WIRED

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.

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).

Searching for alien life in Mars photos

From Martian rats to mysterious women, alien hunters say the photos from the Mars rover prove there's life on the red planet. CNN's Ian Lee investigates.

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.

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.

Searching the Universe for Extraterrestrial Life: A Timeline

Though humans have long looked to the stars, the history of human interest in alien life is relatively recent. Here’s a look back at how humans have throughout history looked for life in the final frontier.

Is There Intelligent Life On Other Planets?

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?

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!.
