The search for near-Earth-size exoplanets is on.
Although 1000's of exoplanets have been discovered, few are near-Earth-size.
But that doesn't mean they don't exist.
Now, teams at JPL are working on creative new technologies to not only discover these elusive
planets but expand our search for signs of life beyond our solar system.
NASA 360 joins Stuart Shaklan of NASA's Jet Propulsion Laboratory as he discusses future of
exoplanet discovery.

In the search for life beyond Earth, false alarms abound. Researchers have generally
considered, and rejected, claims ranging from a 1970s report of life on Mars to the 1990s
discovery of fossilized space microbes in a meteorite.
Now, inspired by the detection of thousands of planets beyond the Solar System, NASA has
started a fresh effort to learn how  to recognize extraterrestrial life. The goal is to
understand what gases alien life might produce and how Earth-bound astronomers might detect
such biosignatures in light passing through the atmospheres of planets trillions of
kilometers away (see Searching for alien life). The effort comes at a crucial time, as
astronomers grapple  with how to interpret exoplanet data from the next generation of telescopes.
Some scientists are working to understand how nature could produce archetypal biosignature
gases, such as oxygen, in the absence of living organisms. Others are trying to think as
expansively as possible about the types of biochemistry that could sustain life. "We could
fool ourselves into thinking a lifeless planet has life or we could be missing life because
we don't really understand the context of what could be produced on another planet",
says Sarah Rugheimer, an astronomer at the University of St Andrews, UK. Detecting a
biosignature gas is just the first step to understanding what could be happening on an exoplanet.
Each world has its own combination of physical and chemical factors that may or may not lead to
life, says Victoria Meadows, an astronomer at the University of Washington in Seattle. Planets
are hard, and we shouldn't think they are all going to be the same or reveal their secrets
very easily, she says. A planet's environment is key. Some Earth-sized planets orbit M dwarf
stars  the most common type of star in the Galaxy at the right distance to harbor liquid water.
But Meadows' collaborators have shown that photo-chemical reactions can send water into the
planet's atmosphere and then break off its hydrogen, which escapes into space. What's left
is a thick blanket of oxygen that might seem as if it came from living organisms, but results
from a run-away greenhouse effect.

The Original 1974 message

What's this? this is the original speculative message sent out in November 1974 and the
 response(?) found as a crop glyph in southern England.

The Arecibo Message is Answered by Aliens in a Mind Blowing Crop Circle! The Arecibo message
was beamed into space a single time (not repeated) via frequency modulated radio waves at a
ceremony to mark the remodeling of the Arecibo radio telescope on 16 November 1974.

 The question is, are they alien or are they natural?

some clarification should be made as to what SETI and METI
are all about and what sets them apart.

The term METI was coined by Russian scientist Alexander Zaitsev, who sought to draw a
 distinction between SETI and METI.
As he explained in a 2006 paper on the subject:
The science known as SETI deals with searching for messages from aliens.
METI science deals with the creation of messages to aliens.
 Thus, SETI and METI proponents have quite different perspectives. SETI scientists are in a
 position to address only the local question - does Active SETI make sense? In other words,
 would it be reasonable, for SETI success, to transmit with the object of attracting ETI's
 In contrast to Active SETI, METI pursues not a local and lucrative impulse, but a more global
 and unselfish one to overcome the Great Silence in the Universe, bringing to our
 extraterrestrial neighbors the long-expected annunciation - You are not alone!

Published on Nov 30, 2015
All of the Kepler multi-planet systems (1705 planets in 685 systems as of 24 November 2015)
on the same scale as the Solar System (the dashed lines). The size of the orbits are all to
 scale, but the size of the planets are not. For example, Jupiter is actually 11x larger than
 Earth, but that scale makes Earth-size planets almost invisible (or Jupiters annoyingly large).
The orbits are all synchronized such that Kepler observed a planet transit every time it hits
an angle of 0 degrees (the 3 o'clock position on a clock).
Planet colors are based on their approximate equilibrium temperatures, as shown in the legend.

 complex carbon-based molecule. Both this molecule and its simpler cousin hydrogen cyanide
 (HCN) were found in the cold outer reaches of the star�s newly formed disk, in a region
 that astronomers believe is analogous to our own Kuiper Belt -- the realm of icy
 planetesimals and comets beyond Neptune.

Magnetic field on a terrestrial planet
Nearly four billion years ago, life arose on Earth. Life appeared because our planet had a
 rocky surface, liquid water, and a blanketing atmosphere. But life thrived thanks to another
 necessary ingredient: the presence of a protective magnetic field.

Life Beyond Earth

Gravitational Lens of the Sun: Its Potential for Observations and Communications
over Interstellar Distances

Abstract The gravitational field of the sun acts as a spherical lens to magnify the intensity of radiation from a distant source along a semi-infinite focal line. A spacecraft anywhere on that line in principle could observe, eavesdrop, and communicate over interstellar distances, using equipment comparable in size and power with what is now used for interplanetary distances. If one neglects coronal effects, the maximum magnification factor for coherent radiation is inversely proportional to the wavelength, being 100 million at 1 millimeter. The principal difficulties are that the nearest point on the focal half-line is about 550 times the sun-earth distance, separate spacecraft would be needed to work with each stellar system of interest, and the solar corona would severely limit the intensity of coherent radiation while also restricting operations to relatively short wavelengths.

Communicating Across the Cosmos (Morris Jones)

Published on Nov 11, 2014
A Journalistic Perspective on SETI-Related Message Composition
The selection of content for SETI-related communications (sometimes known as CETI, for
 Communication with Extraterrestrial Intelligence) in deep space has been orchestrated
 largely by scientists and other academics. But human civilization largely chronicles its
 own activities through journalism and the mass media. The potential contributions of a
 journalistic perspective to SETI-related message composition are generally ignored. This
 paper examines how criteria of perception and reportage practiced by journalism could
 influence SETI-related communications.

Astronomers Eavesdrop On Nearby Star System To Find Aliens

Scientists are doing everything they could to find proof of living aliens, even eavesdropping.
 (Image used for representation only.) bertomic / Pixabay CC BY 1.0
 Researchers on a hunt for extraterrestrial intelligence have reportedly taken the help of a
 powerful radio telescope to tune in to a neighboring star system, which is located relatively
 near to our planet. The aim of the scientists is to detect any sound, howsoever weak, that
 could signal the existence of an alien civilization. Astronomers from the SETI Institute used
 the Allen Telescope Array (ATA) in California to eavesdrop on Trappist 1, a red dwarf star
 system that has at least three habitable exoplanets to see if it is transmitting radio waves.
 Last year Kepler had detected a mysterious transit signal from a star known as Tabby's star,
 officially called KIC 8462852. The transit, which basically measures the dimness in the
 brightness of a star when a planet orbits it, was nothing like ever seen before because the
 brightness dimmed by 20 percent. Scientists were puzzled by the occurrence, and suggested
 that a swarm of comets may have been the cause of the strange signal.

Dishdance, a tribute to radio telescopes
This new and beautiful video called Dishdance is part of project Skyglow.
It's a beautiful timelapse medley of radio astronomy facilities.

NOTE TO OUR READERS: When this video was released earlier today, it featured the voice of the
 late Carl Sagan speaking about the Search for Extraterrestrial Intelligence (SETI). The Carl
 Sagan folks Druyan-Sagan Associates in Ithaca, New York have asked that the voiceover be
 removed and want 6-8 weeks to evaluate whether it can be included here. Maybe Sagan's voice
 will return to enhance this video, but, in the meantime, enjoy it. It's still an awesome video.
This morning, video producer Gavin Heffernan dropped EarthSky a note, saying:

The first modern Search for ExtraTerrestrial Intelligence (SETI) experiment at low radio
 frequencies is underway, as researchers utilise the capabilities of the Murchison Widefield
 Array (MWA) to search the skies for the tell-tale signs of an advanced civilisation.
SETI experiments using radio telescopes first started in 1960 when Cornell University
 astronomer Frank Drake used the Green Bank telescope in West Virginia to examine two
 nearby stars. Since then a number of programmes, such as the Million-channel ExtraTerrestrial
 Assay (META) programme and SERENDIP (Search for Extraterrestrial Radio Emissions from
 Nearby Developed Intelligent Populations) plus offshoots of this experiment, have continued
 to search the skies ever since.

Mysterious Star Pulses May Be Alien Signals, Study Claims
By Mike Wall, Senior Writer
October 28, 2016 01:15pm ET

A study published in October 2016 reported the detection of odd light pulses coming from 234
 of 2.5 million stars observed by the Sloan Digital Sky Survey's 2.5-meter telescope
 in New Mexico (pictured here). These pulses are consistent with signals that intelligent
 aliens might produce, the study authors claimed.
Credit: SDSS/Fermilab Visual Media Services/NASA
Strange pulses of cosmic light might be signals from hundreds of different alien civilizations
 or just the latest false alarm in the tortuous search for ET. This month, astrophysicists
 Ermanno Borra and Eric Trottier, both from Laval University in Quebec, announced that they
 had spotted mysterious light signals coming from 234 different stars in our Milky Way galaxy.
 These pulses match the profile of signals that Borra, in a 2012 paper, predicted intelligent
 aliens might use to get our attention, the authors wrote.

Astronomers at the University of Michigan have taken close-up pictures of a nearby star that
 show starspots, sunspots outside our solar system. The researchers have used a technique
 called interferometry to build essentially the first time lapse of zeta Andromedae across one
 of its 18-day rotations. Zeta Andromedae is about 181 light-years away in the northern
 constellation Andromeda.
 A paper on the findings is published in the current issue of Nature.

Technosearch currently has 3 different lists depending on the type of search that was conducted.

Technosearch is a web-based tool that keeps track of SETI papers from 1960 until the present day and allows observers from all over the world to submit their own searches, keeping us current with the times. Technosearch keeps track of the following: the title of the search paper (or the popular name of the search), the name of the observers, the date of the search, the objects observed, the facility at which the search took place, the size of the telescope used, the sensitivity of the instrument used, the resolving power of the instrument, the time that was spent observing each object, the reference where the search can be found in print, the link where the search can be found online, and comments that explain the search strategy and a place where the observer can make note of whatever else they would like to report. Technosearch hosts many SETI related papers that were hosted in old obscure journals and are hard to access otherwise along with papers that were stuck behind payment barriers. The search for technosignatures (evidence that a technology producing civilization existed) will likely take many generations to come to any sort of meaningful conclusion, and in order to search in new places requires that we know where we have already searched. This tool exists to give the astronomers of tomorrow a way to look into the past and see where and how we searched today.



This is a list containing the SETI searches looking for signals in the Radio part of the EM spectrum. This list contains the first SETI observations written in the 1960s up to present day searches being conducted by teams all over the world.

Do Any Exoplanets Have Intelligent Occupants? (SETIcon 2)

Jon M. Jenkins - Jon is the Analysis Lead for Kepler, which means that he heads up a group of
 about two dozen scientists and programmers who designed and built the software that makes
 this dramatic search for other worlds possible. With a brightness precision of 20 parts per
 million, Kepler should be able to discover planets that are the same size as the rocky,
 inner orbs of our own solar system. By making an inventory of such worlds, Kepler will answer
 one of the most intriguing questions in astrobiology:
 are Earth-size planets abundant or rare?

Revised scale of significance of ET detection published

A group of SETI astronomers led by Duncan Forgan, and including myself and BSRC director
 Andrew Siemion, has published a revised version of the Rio Scale . The Rio Scale is designed
 to predict the public impact a signal would have, like the Richter scale does for
 earthquakes. The prior version of the Rio scale, in addition to being rarely used, tended to
 overestimate the impact of low quality or low significance reports of detection.
Now all we have to do is convince other SETI astronomers and the press to use it.

Article from Wired Magazine on the revised Rio scale

Planets Everywhere: The 7th Kepler Planet Catalog - Fergal Mullally (SETI Talks)

Published on Dec 4, 2015
Dr. Mullally will present the 7th catalog of Planet Candidates found by Kepler. Uniformly vetted lists of detected planet candidates are a key step towards measuring the occurrence rates of planets, as well as providing interesting individual objects for potential follow-up. The 7th catalog includes 8826 objects of interest, of which 4696 are deemed viable planet candidates.

This catalog is the first to be uniformly vetted in an entirely objective manner by algorithm, instead of by manual inspection. This algorithmic approach enables us to test our results against simulated data sets allowing us to measure our performance for the first time. Dr. Mullally will discuss some novel features of the vetting pipeline, discuss the performance and limitations, and highlight some interesting individual planets.

Communicating Across the Cosmos Workshop (Seth Shostak)

Published on Nov 10, 2014
For over a half century, astronomers involved in the Search for Extraterrestrial Intelligence
 (SETI) have scanned the skies for signals from distant civilizations. Would humans be able to
 decode information-rich signals from another planet? Could we create a "universal language"
 that would be meaningful to an independently evolved civilization?
To help answer these questions, on November 10-11 2014 the SETI Institute convened a
 multidisciplinary, international workshop at its headquarters in Mountain View, California.
 Speakers from six countries drew on disciplines ranging from astronomy and mathematics, to
 anthropology and linguistics, as they debated the best ways to create meaningful messages.
 While the two-day workshop was closed to the public, all talks will be posted on the SETI
 Institute's YouTube channel.
On the day following the workshop, several of the speakers will summarize the key ideas
 discussed as part of the SETI Institute's public weekly colloquium series, held on November
 12, at 12:00 noon.

SETI@home: Educational materials on life in the Universe

SETI@home: Educational materials on life in the Universe

Berkeley SETI Research Center's Dr. Steve Croft, in collaboration with colleagues at UC Museum
 of Paleontology and the Space Sciences Laboratory's "Multiverse" education group have put
 together an educational site focusing on the conditions needed for life to arise in the
 Universe. Although aimed primarily at high school teachers and their students, this material
 may be of interest to broader audiences. In the "Research Profiles" section of the site you
 can also find an interview with BSRC's Dr. Eric Korpela, Director of SETI@home.

Steve Croft - Breakthrough Listen: Expanding the Search for Life Beyond Earth

Published on Jul 5, 2016
For millennia humans have gazed at the stars and asked, "Are we alone in the Universe?". In the past few decades, we have discovered that many of the pinpoints of light scattered across our night sky are suns that host worlds similar to our own. Still, though, the question remains unanswered as to whether minds have arisen elsewhere, or if life as we know it is rare, or indeed unique. Dr. Croft will describe some of the work taking place at UC Berkeley that attempts to answer this question. These efforts include one of the largest computing projects in existence, as well as the recently-launched $100 million Breakthrough Listen project that dramatically expands the search, and applies modern Silicon Valley techniques to the data analysis. Dr. Croft will also describe how the public can participate in this expansion of the search for life beyond Earth.

Dr. Steve Croft is a researcher in the UC Berkeley Astronomy Department. He grew up in England, where he received a PhD in astrophysics from Oxford University in 2002, before moving to California to work as a postdoctoral researcher at the Lawrence Livermore National Laboratory. Since 2007, Croft has been a researcher in the Astronomy Department at UC Berkeley. He splits his time between studies of supermassive black holes and exotic transient events using the Murchison Widefield Array in the remote Western Australian outback, and research and public outreach with Berkeley SETI Research Center and the Breakthrough Listen project. Dr. Croft has a deep commitment to public communication of science, including through projects such as NOVAS, that connected underrepresented students to NASA science through art and visualization, and as the founder and coordinator of the Science@Cal Lecture Series.

This Section for Reports

The search for life in the solar system and beyond has to date been governed by a model based
 on what we know about life on Earth (terran life). Most of NASA's mission planning is focused
 on locations where liquid water is possible and emphasizes searches for structures that
 resemble cells in terran organisms. It is possible, however, that life exists that is based
 on chemical reactions that do not involve carbon compounds, that occurs in solvents other
 than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA
 incorporate this possibility in its efforts to search for life, the NRC was asked to carry out
 a study to evaluate whether nonstandard biochemistry might support life in solar system and
 conceivable extrasolar environments, and to define areas to guide research in this area.
 This book presents an exploration of a limited set of hypothetical chemistries of life, a
 review of current knowledge concerning key questions or hypotheses about nonterran life, and
 suggestions for future research.

A Breakthrough Initiatives Launch Highlights Breakthrough

Published on Feb 16, 2016
To learn more about Breakthrough Listen and the Breakthrough Initiatives,
The Breakthrough Initiatives were launched at the Royal Society in London on July 20, 2015.
 The Initiatives were announced by Yuri Milner, Stephen Hawking, Martin Rees, Frank Drake,
 Pete Worden and Ann Druyan. The Breakthrough Initiatives seek scientific evidence of life in
 the Universe.
 The first initiative is Breakthrough Listen, the most comprehensive, intensive and sensitive
 search ever undertaken for artificial radio and optical signals. It is a complete survey of
 the 1,000,000 nearest stars, the plane and center of our galaxy, and the 100 nearest
 galaxies. All data will be open to the public.

HD164595. But the signal is provocative enough that the
RATAN-600 researchers are calling for permanent monitoring of this target.

 together with expected shape of the signal for point-like source in the position of HD
 164595. Credit: Bursov et al.
From the presentation:
The estimated probability ~2 X 10-4 to simulate the signal from the direction of the HD164595
 by signal-like noise is small, therefore HD164595 is good candidate SETI. Permanent
 monitoring of this target is needed.
All of which makes excellent sense. We can't claim the detection of an extraterrestrial
 civilization from this observation. What we can say is that the signal is interesting and
 merits intense scrutiny.

 directly observe the atmospheres of distant worlds. We know there's life on Earth, and our
 atmosphere tells the tale, so can we do the same thing with extrasolar planets? It turns out,
 coming up with a single biosignature, a chemical in the atmosphere that tells you that yes,
 absolutely, there's life on that world, is really tough.

 Review of Bio signatures (pdf)
I've got to admit, I've been pretty bad for this in the past. In old episodes of Astronomy
 Cast and the Weekly Space Hangout, even here in the Guide to Space, I've said that if we
 could just sample the atmosphere of a distant world, we could say with conviction if there's
 life there. Just detect ozone in the atmosphere, or methane, or even pollution and you could
 say, there's life there. Well, future Fraser is here to correct past Fraser. While I admire
 his naive enthusiasm for the search for aliens, it turns out, as always, things are going to
 be more difficult than we previously thought.
Astrobiologists are actually struggling to figure out a single smoking gun biosignature that
 could be used to say there's life out there. And that's because natural processes seem to
 have clever ways of fooling us. What are some potential biosignatures, why are they
 problematic, and what will it take to get that confirmation?

What is Direct Imaging?

n the past few decades, the number of planets discovered beyond our Solar System has grown by leaps and bounds. As of October 4th, 2018, a total of 3,869 exoplanets have been confirmed in 2,887 planetary systems, with 638 systems hosting multiple planets. Unfortunately, due to the limitations astronomers have been forced to contend with, the vast majority of these have been detected using indirect methods.

HR 8799 in Motion (Official)

Yes, we are in the era of watching planets orbit other stars. HR 8799 harbors four super-Jupiters orbiting with periods that range from decades to centuries. Motion interpolation was used on 7 images of HR 8799 taken from the Keck Telescope over 7 years to create this image.

M. Keck Observatory We wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain.

Want to Find Aliens? The Largest Dataset in the History of SETI has Been Released to the Public

In 2016, Russian-Israeli billionaire Yuri Milner launched Breakthrough Initiatives, a massive non-profit organization dedicated to the search for extra-terrestrial intelligence (SETI). A key part of their efforts to find evidence of intelligent life is Breakthrough Listen, a $100 million program that is currently conducting a survey of one million of the nearest stars and the 100 nearest galaxies.
