Falling Snow Spotted On Mars And Searching For Alien Laser Beacons

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:

g ABODES -NASA's Phoenix spacecraft has discovered evidence of past water at its Martian landing site and spotted falling snow for the first time, scientists reported Monday. Soil experiments revealed the presence of two minerals known to be formed in liquid water. Scientists identified the minerals as calcium carbonate, found in limestone and chalk, and sheet silicate. See article.

g MESSAGE -In 2001, California astronomers broadened the search for extraterrestrial intelligence with a new experiment to look for powerful light pulses beamed our way from other star systems. Scientists from the University of California's Lick Observatory, the SETI Institute, UC-Santa Cruz, and UC-Berkeley used the Lick Observatory's 40-inch Nickel Telescope with a new pulse-detection system capable of finding laser beacons from civilizations many light-years distant. Unlike other optical SETI searches, this new experiment is largely immune to false alarms that slow the reconnaissance of target stars. See article.

g COSMICUS - The space walk by Chinese Air Force Colonel Zhai Zhigang, 42, on Sunday was the latest in a long series of grand gestures with which nations announce their stake in the exploration of space. See article.

g IMAGINING -In our current cultural fascination with the idea of alien beings from other worlds, most of it hokey at best and just plain wrong at worst, there is a definite need for some popular-level literature which helps to sort the rational wheat from the pseudoscience and Hollywood chaff. SETI scientist Seth Shostak wrote such a book, "Sharing the Universe," in 1998. Shostak gives a comprehensive and most readable survey of what we do (and especially do not) know about life beyond the planet Earth, and how we are going about searching for our fellow inhabitants of the universe. See article.

g AFTERMATH - Scientists such as the SETI Institute's John Billingham and Jill Tarter have taken the lead in planning for the day we might receive a signal from life beyond Earth. Working with diplomats and space lawyers, they have helped develop protocols that guide the activities of SETI scientists who think they may have detected extraterrestrial intelligence. See article.

More Water On Moon Than Thought And False Claims Of Eti Contact

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g ABODES - Scientists have discovered that the Moon has much more water than previously thought. The research could change concepts about how the Moon formed. Water on the Moon could also be an important resource for future explorers. See article.g MESSAGE - Non-professional involvement in SETI science, which is encouraged by the nonprofit SETI League, Inc., increases the opportunity for the perpetration of hoaxes. The SETI League has already been peripherally involved in three separate false claims of ETI contact. Two were simple cases of mistaken identity, easily rectified. But the third was an elaborate hoax perpetrated by an Internet hacker who broke into a closed signal verification e-mail list. Such claims call for a prompt but measured response, so as not to subject the SETI community to charges of complicity in conspiracy or cover-up activities. In this presentation SETI League Executive Director H. Paul Shuch explores the dilemma of encouraging grass-roots participation, while avoiding association with fraudulent and pseudo-scientific claims See article.g AFTERMATH - The scientific discussion of the evolution of life in the universe raises some key philosophical and theological issues Will life and intelligence be found throughout the universe, or will it turn out to be exceedingly rare? Will intelligent life be capable of both rationality and moral agency? Will evolutionary biology determine its moral content or will it merely bequeath intelligent life with moral capacity, leaving moral content to be determined independently of biology? If moral agency evolves, will these species inevitably exhibit moral failure, or is our generic human experience of moral failure strictly the result of our particular evolution, leaving us to expect there to be other civilizations that are entirely benign? The discussion of these issues, though largely hypothetical, can offer insight into the theological and cultural implications of the discovery of extraterrestrial intelligence as well into a better understanding of the human condition.

Burnt Out Stars Show Evidence Rocky Planets Are Common

Burnt-out stars show evidence rocky planets are common...

Science Daily - The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet assembly is common in clusters, say researchers.

The stars, known as white dwarfs -- small, dim remnants of stars once like the Sun -- reside 150 light-years away in the Hyades star cluster, in the constellation of Taurus (The Bull). The cluster is relatively young, at only 625 million years old.

Astronomers believe that all stars formed in clusters. However, searches for planets in these clusters have not been fruitful -- of the roughly 800 exoplanets known, only four are known to orbit stars in clusters. This scarcity may be due to the nature of the cluster stars, which are young and active, producing stellar flares and other outbursts that make it difficult to study them in detail.

A new study led by Jay Farihi of the University of Cambridge, UK, instead observed "retired" cluster stars to hunt for signs of planet formation .

Hubble's spectroscopic observations identified silicon in the atmospheres of two white dwarfs, a major ingredient of the rocky material that forms Earth and other terrestrial planets in the Solar System. This silicon may have come from asteroids that were shredded by the white dwarfs' gravity when they veered too close to the stars. The rocky debris likely formed a ring around the dead stars, which then funnelled the material inwards. "Keep on reading..."

Nasa Web Follow The Dust To Find Planets

NEWS NOVEMBER 10, 2014

FOLLOW THE DUST TO FIND PLANETS

This artist's concept depicts giant planets circling between belts of dust. Scientists think the star system HD 95068 may have a planetary architecture similar to this. While the star system's two dust belts are known, along with one massive planet, more giant planets may lurk unseen. Image credit: NASA/JPL-Caltech

> Larger imageResearchers studying what appears to be a beefed-up version of our solar system have discovered that it is encased in a halo of fine dust. The findings are based on infrared data from NASA's Spitzer Space Telescope and the European Space Agency's Herschel Space Observatory, in which NASA is a partner.The dusty star system, called HD 95086, is located 295 light-years from Earth in the constellation Carina. It is thought to include two belts of dust, which lie within the newfound outer dust halo. One of these belts is warm and closer to its star, as is the case with our solar system's asteroid belt, while the second belt is cooler and farther out, similar to our own Kuiper belt of icy comets."By looking at other star systems like these, we can piece together how our own solar system came to be," said Kate Su, an associate astronomer at the University of Arizona, Tucson, and lead author of the paper.Within our solar system, the planets Jupiter, Saturn, Uranus and Neptune are sandwiched between the two dust belts. Scientists think something similar is happening in the star system HD 95086, only on larger scales. One planet, about five times the mass of Jupiter, is already known to sit right inside HD 95086's cooler belt. Other massive planets may be lurking between the two dust belts, waiting to be discovered.Studies like this from Spitzer and Herschel point the way for ground-based telescopes to snap pictures of such planets in hiding, a technique referred to as direct imaging. The one planet known to exist in HD 95086 was, in fact, discovered and imaged using this technique in 2013. The images aren't sharp because the planets are so faint and far away, but they reveal new information about the global architecture of a planetary system."By knowing where the debris is, plus the properties of the known planet in the system, we can get an idea of what other kinds of planets can be there," said Sarah Morrison, a co-author of the paper and a PhD student at the University of Arizona. She ran computer models to constrain the possibilities of how many planets are likely to inhabit the system. "We know that we should be looking for multiple planets instead of a single giant planet."To learn what HD 95086 looks like, the astronomers turned to a similar star system called HR 8799. It too has an inner and outer belt of debris surrounded by a large halo of fine dust, and four known planets between the belts -- among the first exoplanets, or planets beyond our solar system, to be directly imaged.Comparing data from the two star systems hints that HD95086, like its cousin HR 8799, is a possible home to multiple planets that have yet to be seen. Ground-based telescopes might be able to take pictures of the family of planets.Both HD 95086 and HR 8799 are much younger and dustier than our solar system. When planetary systems are young and still forming, collisions between growing planetary bodies, asteroids and comets kick up dust. Some of the dust coagulates into planets, some winds up in the belts, and the rest is either blown out into a halo, or funneled onto the star.Herschel and Spitzer are ideally suited to study the dust structures in these systems, which glow at the infrared wavelengths the telescopes detect.The researchers will present the findings at the Division for Planetary Science Meeting of the American Astronomical Society held in Tucson, Arizona from Nov. 8 to 15.Read more about the research at:http://uanews.org/story/baby-photos-of-a-scaled-up-solar-systemOther coauthors of the paper include Zoltan Balog at the Max-Planck Institute of Astronomy, Heidelberg, Germany, and Renu Malhotra, Paul Smith and George Rieke of the University of Arizona.NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Spitzer Space Telescope mission for NASA's Science Mission Directorate, Washington.

Will India Reveal The Existence Of The Ufo Bases On The Moon

The spacecraft, was launched on October 22, India is on its way to moon. But there is a major debate in process within Indian Government and Indian Space Research Organization. The debate is on telling the truth to the world about the existence of the UFO bases in the moon.

The Indian spacecraft carrying 11 payloads (scientific instruments) weighs about 1,380 kg at the time of its launch.

The spacecraft is shaped like a cuboid with a solar panel projecting from one of its sides. The state-of-the-art sub-systems of the spacecraft facilitate safe and efficient functioning of its 11 payloads.

It is powered by a single solar panel generating a maximum power of 700W. A 36 Ampere-Hour (AH) Lithium ion battery supplies power when the sun does not illuminate the solar panel.

"To make Chandrayaan-1 escape from orbiting the earth and to travel towards the moon, its Liquid Apogee Motor (LAM) is used. Liquid propellants needed for LAM as well as thrusters are stored onboard the spacecraft.

The craft's dual gimbaled antenna is transmitting scientific data gathered by its 11 payloads to earth.

India may surprise the world. The surprise may come any time. The country must reveal the existence of the underground infrastructure of UFO bases.

Anthony Wesley Jupiter Slamed By Massive Object Amature Astronomer Discovery

Impact Jupiter...Massive object slams into Jupiter a few days ago, discovered by Australian amateur astronomer Anthony Wesley.Commet or asteroid smashes into Jupiter a few days ago, discovered by Anthony Wesley in Australia.An amateur astronomer, Anthony Wesley, has discovered a rare space phenomenon of a massive object about the size of earth smashing into the surface of our celestial planetary neighbor Jupiter from his backyard in the Australian capital of Canberra.44-year-old computer programmer Anthony Wesley was stunned to have discovered a massive black hole on the surface of Jupiter using a 14.5 inch telescope.Within hours of Anthony Wesley's amazing discovery of the impact of the massive object into Jupiter, science and space blogs, message boards and news web sites were buzzing with the amazing discovery.Not long after the discovery by Anthony Wesley, astronomers from NASA via a telescope at Mauna Kea in Hawaii were confirming that indeed Jupiter had just been hit by a massive object.The amazing discovery by Anthony Wesley is only the second time evidence of such a collision with Jupiter has been documented.The other time was back in July 1994 when the Shoemaker-Levy 9 comets collided with Jupiter. The timing of the celestial collision with the massive planet came almost 15 years to the day one of the events of 1994 happened.Picture: Australian Anthony Wesley"We are extremely lucky to be seeing Jupiter at exactly the right time, the right hour, the right side of Jupiter to witness the event. We couldn't have planned it better," a spokesperson from NASA said.Its not known the exact nature of the massive object that has slammed into Jupiter, but its almost certainly a massive asteroid or comet.The suddenly world famous Anthony Wesley told his story to Australian media: "By two o'clock I'd come back up to the house and was sending alerts to all the people I could think of that should be looking at this and especially the professional astronomers with specialised instrument for measuring this," Anthony Wesley said."The sooner they could see this the more interesting and more useful science they can get from it."Wesley said it took him 30 minutes to realise a dark spot rotating in Jupiter's clouds on July 19 was actually the first impact seen by astronomers since a comet collided with the giant planet in July 1994."I thought (it) likely to be just a normal dark polar storm," Anthony Wesley said earlier on his website www.acquerra.com.au/astro."However as it rotated further into view and the conditions improved I suddenly realised that it wasn't just dark, it was black in all channels, meaning it was truly a black spot," Anthony Wesley addedThe race is now on to find any evidence that might show the exact moment of impact, with astronomers world wide scrambling to see if anyone had a telescope pointed at Jupiter at the time of impact.It was also noted by online blogs that if the object had hit the Earth, the planet would have been pulverised.The Anthony Wesley discovery of the Jupiter impact is also a reminder the role the massive planet plays at cleaning up massive object that might otherwise find their way to our Earth, threatening global catastrophe.

Support in 2010, the alien invasion film SKYLINE"incorporated real news stories inside its publicity diplomacy. The chaser for the film begins together with courageous symbols against a substantial settle on reading: "ON Noble 28, 2009, NASA SENT A Letter Into Scrap Out of THAN WE Customarily Execution Not obligatory IN AN Be successful TO Close by Outer space Animation."This is test. On the date evident, the Australian government, charge its "Ciao from The human race" science appreciation, and together with the leg of NASA, sent dependable 26,000 (scrupulously vetted) messages from the situation to the extra-solar Earth-like planet Gliese 581d in a single hand on. This proactive system to alien contact open as METI (Messaging Outer space Intelligence) differs from the conservative biddable system favoured by SETI (Examine for Outer space Intelligence), which devotes its pains basically to listening for any up-and-coming hidden alien signals.

The METI system is debatable as dependable scientists make up your mind it impractical to cautiously friendly our spirit in the galaxy to any potentially mechanically delightful civilizations. In April 2010, Schoolteacher Stephen Hawking finished international headlines by stating his definite idea that civilization want intention to help out extraterrestrial contact: "To my statistical brain, the happen lonely call pensive about aliens fitting questioning," Hawking assumed, but extra, notably, "If aliens always slip us, I observe the argue would be far-flung as later than Christopher Columbus first landed in America, which didn't plain-spoken out very well for the American Indians." Hawking suggested that aliens "may well exist in classic ships, having used up all the income from their give shelter to planet" and would by chance be "looking to annihilate and colonise doesn't matter what planets they can have an adverse effect on."

The trailer for the film begins by gallant reproduction unwilling a gigantic rigid reading: "ON Imperial 28, 2009, NASA SENT A Addendum In the sphere of Space Beyond THAN WE Habitually Assumed Everyday IN AN Effort TO Seam Space Chirpiness." This is genuine.

Strange New Worlds

RAY JAYAWARDHANA. STRANGE NEW WORLDS - THE SEARCH FOR ALIEN PLANETS AND LIFE BEYOND OUR SOLAR SYSTEM. PRINCETON UNIVERSITY PRESS, 2011 "- Reviewed by David Simpson."There is little doubt the discovery of tell-tale signs of life elsewhere in the universe, let alone the receipt of an indisputably alien radio signal, would have massive implications for mankind - the first sign that life is not unique to Earth.This book takes us through the history of our quest for knowledge of the heavens, from Greek philosophers in the fifth century BC, through advances in astronomical observation methods, to the latest space telescopes. Finally it speculates a decade or more to the future, by when the author feels astronomers will probably have the means to detect the first signs of life elsewhere. It is not about SETI, not the long-standing attempt to detect intelligent alien radio signals, but rather how incremental advances in telescopes now mean that, for the first time, we are able to detect planets orbiting distant stars - albeit planets much larger than Earth and inhospitable to life [as we know it, Jim] - and to infer something about their likely properties. The title "Strange New Worlds" is perhaps a bit misleading as astronomers haven't yet found any new worlds of the might-contain-life variety and those they have found are not strange in the wholly unexpected sense. They have detected an impressive number in the 'almost certainly won't contain life' category, for example gas-giants like Jupiter, and rocky planets baking at 200 ^0C or more. Similarly misleading is the sub-title "The Search for Alien Planets"... hinting that astronomers are searching specifically for planets containing aliens, when they are not, and "Life Beyond Our Solar System" is last-chapter speculation about what future, more sensitive astronomical measurements might find. But I guess "A History of Man's Search for Exoplanets" would probably not sell so well. The subject's chronology is presented in detail, is well referenced and gives credit to many of the main scientists involved. Their biographical stories are interesting too, although extending this to the scientists' parents and even grandparents seems a bit much, as did the tedious information about who did a PhD under whom. I would have preferred the space to be used for a sentence or two here and there on the technical benefits of newer instruments, for example what was it about digital cameras and spectrographs that brought improved measurements? For non-astronomers like me the countless indecipherable alphanumeric strings of star identifiers were quite numbing but probably have to be there and were easily skipped. The principles employed in detecting extrasolar planets are clearly explained, such as: measuring the tiny cyclic changes in the Doppler shift of light from a distant star - indicating the gravitation tug of an orbiting planet; 'microlensing'not - looking at starlight as it is bent and amplified by the gravitational field of a large intervening object or; transit measurements - measuring the periodic changes in star brightness as it is eclipsed by an orbiting planet. It is fascinating to appreciate the changes in scientific attitude towards the subject, from the 1980s when bothering to searching for extraterrestrial planets or even whether it was a legitimate part of astronomy was questioned, to today when vast sums of money are spent funding scientific teams exploring avenues in 'astrobiology'. This includes, for example, working out what constitutes a biosignature - something that indicates the existence of living organisms. Gripes aside, it is an interesting and well written book that doesn't need much technical knowledge to be appreciated.

We Wont Have Enough Power For Interstellar Travel Until At Least 2211 According To New Calculations

Gliese 581 System This artist's concept shows the inner planets of the Gliese 581 system. Planet G, shown in foreground, is thought to be in its star's habitable zone. Unfortunately, we won't be able to visit other solar systems for a very, very long time, according to a new study. Lynette Cook/via NASA Interstellar travel won't be possible for at least 200 years, according to a former NASA propulsion scientist who has some new calculations. And by then, the spaceships we would design for the trip will be obsolete. Forget cost, political will and all the other variables - simply obtaining enough energy will take until 2196, according to Marc Millis, former head of NASA's Breakthrough Propulsion Physics Project and founder of the Tau Zero Foundation, which supports interstellar travel research. Millis did plenty of extrapolating to reach this conclusion, which he presented at an astronomy meeting in Prague last fall and posted to the physics archive this week. He crunched 27 years of data on energy trends, mission energy requirements, individual energy use and even societal priorities, and chose two possible trips: An aimless interstellar colony ship, and a 75-year-long mission to Alpha Centauri. RELATED ARTICLES Voyager 1 Arrives at the Outward Reaches of the Solar Wind, Prepares To Enter Interstellar Space The Pioneer Anomaly, a 30-Year-Old Cosmic Mystery, May Be Resolved At Last Discovery of the First Earth-Like, Habitable Exoplanet Will Be Announced in May of 2011 (Maybe) TAGS Science, Rebecca Boyle, alpha centauri, future spacecraft, interstellar, interstellar probes, interstellar space travel, space exploration, space travel, voyagerMillis examined the energy required to launch the space shuttle during the past 30 years, which is a fraction of the nation's total available energy. He assumes the same ratio will hold for interstellar flight, as Technology Review's arXiv blog explains. For a 500-person ship on a one-way journey, Millis figures you would need at least an exajoule - that's 1018 joules - which is just a little bit less than all the energy consumed by the entire world in one year. For an unmanned ship destined for Alpha Centauri, you would actually need more energy, because you'd want to slow it down upon arrival at our nearest neighboring star. This would require 1019 joules. Even without accounting for fuel, the 500-passenger ship wouldn't be able to launch until around 2200 at the earliest, and the A. Centauri probe won't be ready until around 2500. Millis' math is actually more optimistic than other studies, which have suggested you would need 100 times the world's total energy output to cover that distance. Still, it means we all have to live vicariously through Voyager for at least the next few generation
