Photograph: Yuri Beletsky/European Southern Observatory British Astronomers Launch Advanced Planet Search To Look For Signs Of Life -- The Guardian Robotic telescopes in Chile's Atacama desert will conduct Next Generation Transit Survey to analyse atmospheres for clues The art of hunting planets has come so far that astronomers can now list hundreds of alien worlds that orbit stars so faint they are not even visible as pinpricks in the clear night sky. Little is known of these far-flung planets. The most conspicuous are huge, the size of Jupiter, and scorched from circling so close to their suns. Others are giant iceballs, or waterworlds, or even rocky like Earth. But the finer details are a mystery, the stuff of speculation more than science. Read more .... My Comment: This is what I call exciting work.

New Ways To Hear ET

Despite there being no 'intelligent' signal detected coming from Gliese 581, the new technique could prove useful to future SETI projects (Source: M Kornmesser/ESO)

New Way To Hear Signals From ET's Home -- ABC News (Australia)

The search for extraterrestrial intelligence has a powerful new tool at its disposal, Australian scientists report.

For the first time, a group led by astronomer Professor Steven Tingay from Curtin University have used a sensitive type of radio telescope, known as a very long baseline interferometer, to listen out for radio signals coming from a distant planet.

Famed SETI Astronomer Retiring, Says Discovery Of Alien Life ‘Very Close’ -- National Post

Jill Tarter has devoted most of her adult life to the mission of scanning the sky, in the hopes of one day discovering a signal from above that would finally reveal that human beings are not alone in the universe.

One of the world’s most famous astronomers, she has spent nearly 30 years as the director of the Center for SETI Research at the SETI Institute in Mountain View, Calif., the world’s preeminent scientific organization devoted to the search for extraterrestrial intelligence (SETI) and astrobiology, or simply, the evidence of aliens.

The 'Wow!' Signal


The 'Wow!' Signal: One Man's Search for SETI's Most Tantalizing Trace of Alien Life -- The Atlantic

For decades, Robert Gray has been trying to duplicate the most surprising and still-unexplained observation in the history of the search for extraterrestrial life.

Late one night in the summer of 1977, a large radio telescope outside Delaware, Ohio intercepted a radio signal that seemed for a brief time like it might change the course of human history. The telescope was searching the sky on behalf of SETI, the Search for Extraterrestrial Intelligence, and the signal, though it lasted only seventy-two seconds, fit the profile of a message beamed from another world. Despite its potential import, several days went by before Jerry Ehman, a project scientist for SETI, noticed the data. He was flipping through the computer printouts generated by the telescope when he noticed a string of letters within a long sequence of low numbers---ones, twos, threes and fours. The low numbers represent background noise, the low hum of an ordinary signal. As the telescope swept across the sky, it momentarily landed on something quite extraordinary, causing the signal to surge and the computer to shift from numbers to letters and then keep climbing all the way up to "U," which represented a signal thirty times higher than the background noise level. Seeing the consecutive letters, the mark of something strange or even alien, Ehman circled them in red ink and wrote "Wow!" thus christening the most famous and tantalizing signal of SETI's short history: The "Wow!" signal.

We Should Scour The Moon For Ancient Traces Of Aliens, Say Scientists -- The Guardian

Online volunteers could be set task of spotting alien technology, evidence of mining and rubbish heaps in moon images.

Hundreds of thousands of pictures of the moon will be examined for telltale signs that aliens once visited our cosmic neighbourhood if plans put forward by scientists go ahead.

Passing extraterrestrials might have left messages, scientific instruments, heaps of rubbish or evidence of mining on the dusty lunar surface that could be spotted by human telescopes and orbiting spacecraft.

SETI Project Is Back Online


SETI Project: We're Listening Again, ET -- Mercury News

E.T., you can phone home again.

Forty-two radio telescope dishes near Mount Shasta will again start listening for sounds of intelligent life in the universe this fall after donors -- including actress Jodie Foster -- came up with more than $200,000 to save the Mountain View-based SETI program, made famous by the movie "Contact."

The Allen Telescope Array was shut down in April when the SETI (Search of Extraterrestrial Intelligence) Institute ran short of of money for the project.

Jodie Foster Helps Revive SETI Search For Aliens -- Live Science

E.T., the phone line is open and SETI is waiting for your call. And apparently Jodie Foster, too.

The nonprofit Search for Extraterrestrial Intelligence (SETI) Institute, which was forced earlier this year to shutter its Allen Telescope Array, used to listen for alien signals, due to budget issues, has raised enough money to resume the search for life beyond planet Earth.

The institute reached its goal last week of raising $200,000 to operate the telescope through the end of this year. The funds came from over 2,000 private donors, including the actress Jodie Foster, who played fictional SETI scientist Ellie Arroway in the 1997 movie "Contact."

Mission To Search For Alien Life In Outer Atmosphere

Photo: REUTERS

From The Telegraph:

Life from outer space could be surviving on the outer fringes of the Earth's atmosphere, according to scientists who are to launch a mission to search for bacteria that could be living there.

In science fiction films the search for aliens involves travelling across the galaxy to planets millions of miles away.

But scientists believe they could be close to discovering alien life forms much closer to home – on the outer fringes of Earth's atmosphere.

SETI 2060, Do We Make Contact By Then?


From Discovery News:

This month the National Radio Astronomy Observatory’s Green Bank Science Center is celebrating the 50th anniversary of the modern day search for extraterrestrial intelligence (SETI).

In 1960 a young radio astronomer, Frank Drake, undertook a bold and visionary experiment: He used the 85-foot dish antenna at Green Bank, W.V. to listen for radio signals from extraterrestrial civilizations.

Drake recently retired from the SETI Institute in Palo Alto, Calif., without finding his aliens. He’s not alone. As early as the turn of the last century Nicola Tesla and the father of radio, Guglielmo Marconi, were independently listening for signals from Martians.

Are Aliens Eavesdropping On Us? Not Likely


From Discovery News:

The seeming infinity of stars we see in deep exposures of the Milky Way belies the fact that our galaxy has been dead silent when it comes to detecting a radio or optical signal saying “hello” from any neighboring extraterrestrial civilization.

Maybe extraterrestrials are out there but they might not have gone to the effort and expense of building a powerful radio beam and aiming it at us. This may not be in their annual science budget. Or they simply may not want to make their presence know to the universe, as astrophysicist Stephen Hawking recently warned us not to do.

Our Eavesdropping-On-ET Strategy Not Likely To Work


From Wired Science:

Bad news for SETI: Even with the most sensitive radio telescopes yet designed, humans probably won’t find intelligent aliens by listening in on their phones and televisions, a new study finds.

“Eavesdropping on ET is very hard, even with the latest radio telescopes,” said astronomer Duncan Forgan of the University of Edinburgh, a coauthor of the study. “If we don’t try any other ways of searching for aliens, then we may never find them.”

SETI Releases Its Collected Data To The Public, Wants Open-Source Search For Whatever's Out There

The Allen Telescope Array Radio? What is this, the 1930s? Aliens, hit us back on Twitter. We're @Earth284. SETI, via MSNBC

From Popular Science:

Your chance to spot 50 years' worth of sneakily concealed aliens.

Over the past decade, those who wished to contribute to SETI's mission of locating life elsewhere in the universe could leave their computers on running a special screensaver and donate their unused computing power to the cause. Now, SETI director Jill Tarter is asking people around the globe to get more involved in the Search for Extraterrestrial Intelligence by opening up SETI's servers to the public calling for a worldwide, open source contribution to the search.

Happy 50th Birthday To The Search For Extraterrestrial Intelligence!

SETI's Allen Telescope Array via SETI Institute

From Popular Science:

Celebrating half a century of no aliens

Fifty years ago today, on April 8th, 1960, a Cornell astronomy professor named Frank Drake pointed a radio telescope at the star Tau Ceti in the hope of hearing broadcasts from extraterrestrial intelligence. Naturally, he didn't hear anything out of the ordinary. But with this experiment, Drake began the decades-long search for aliens, known as the Search for Extraterrestrial Intelligence (SETI), that celebrates its 50th anniversary today. Over the last half century, SETI has failed at its initial goal of contacting aliens, but succeeded mightily in bringing new attention to astronomy, helping to develop cloud computing, and inspiring generations of new scientists.

We Will Find 'Twins Of Earth' This Year, Says Astronomer Michel Mayor

From Times Online:

Scientists will have detected the first truly Earth-like planet outside the solar system by the end of the year, one of the world’s leading astronomers predicted yesterday.

Professor Michel Mayor, of Geneva University, who led the team that discovered the first extrasolar planet (or exoplanet) in 1995, said he was confident that a planet of a similar size and composition to Earth would be found in the near future.

Addressing a Royal Society conference to mark the 50th anniversary of the Search for Extra-Terrestrial Intelligence (SETI) programme, he said: “The search for twins of Earth is motivated by the ultimate prospect of finding sites with favourable conditions for the development of life. We’ve entered a new phase in this search.”

From The Telegraph:

The Search for Extraterrestrial Intelligence, or SETI, is 50 years old this month. We look at 10 memorable events in the search for life on other planets.

SETI was founded in response to a September 1959 Nature journal article, “Searching for Interstellar Communication”, which suggested that a systematic search for alien life was worthwhile.

Since then, it has spent 50 years listening to the stars with radio telescopes, and at times trying to send messages of its own to other planets.

Here are 10 of the most significant events in mankind’s search for other life.

SETI And The Singularity

From The Futurist:

The Search for Extra-Terrestrial Intelligence (SETI) seeks to answer one of the most basic questions of human identity - whether we are alone in the universe, or merely one civilization among many. It is perhaps the biggest question that any human can ponder.

The Drake Equation, created by astronomer Frank Drake in 1960, calculates the number of advanced extra-terrestrial civilizations in the Milky Way galaxy in existence at this time. Watch this 8-minute clip of Carl Sagan in 1980 walking the audience through the parameters of the Drake Equation. The Drake equation manages to educate people on the deductive steps needed to understand the basic probability of finding another civilization in the galaxy, but as the final result varies so greatly based on even slight adjustments to the parameters, it is hard to make a strong argument for or against the existence of extra-terrestrial intelligence via the Drake equation. The most speculative parameter is the last one, fL, which is an estimation of the total lifespan of an advanced civilization. Again, this video clip is from 1980, and thus only 42 years after the advent of radio astronomy in 1938.

Will We Soon Find Life in the Heavens?

Allen Telescope Array

From U.S. News And World Report:

Alien-hunting scientists have had an eventful year, and they're about to get busier. In just the past few months, life-friendly soil and ice turned up on Mars, astronomers bagged a trio of Earth-like planets in a distant star system, and scientists looking closer to home reported that certain hardy microbes thrive below Earth's ocean floor—a big clue that life may exist on planets that at first glance appear inhospitable.

None of the findings shout, "Here be aliens!" but each report has stoked optimism among astrobiologists that they will discover life beyond Earth. Some leading stargazers, in fact, suspect we're now on the verge of learning that we're not alone—and that genesis wasn't a unique event.

In space, "everywhere we look, we see the same processes that we think led to the origin of life on Earth," says John Rummel, NASA's senior scientist for astrobiology.

In the coming months, two new tools will greatly expand astrobiologists' capacity to hear and see other promising signs of life. Later this summer, the nonprofit SETI Institute, named with the acronym for the search for extraterrestrial intelligence, will begin listening for alien broadcasts on the new $50 million Allen Telescope Array. A spread of 42 radio dishes in California's Cascade Mountains, the array is the first such facility built specifically to listen for E.T. "We're looking for life that's clever enough to hold up its side of the conversation," says Seth Shostak, a senior astronomer at the SETI Institute. The array, half funded by Microsoft mogul Paul Allen, will search for alien signals at a clip "hundreds to thousands times faster" than current SETI projects, says Shostak.
