Habitable Planet Statistics - Claudio Maccone (SETI Talks) SETI Talks Archive: In this lecture Dr. Maccone will provide a statistical equation that we call Statistical Equation for Habitables (SEH) as well as its relationship to the Statistical Fermi Paradox. He will start by noting that the statistics of habitable planets may be based on a set of ten (and possibly more) astrobiological requirements first pointed out by Stephen H. Dole in his book "Habitable planets for man" (1964). He will then provide the statistical generalization of the original (too simplistic) Dole equation by replacing a product of ten positive numbers by the product of ten positive random variables. This is called the "Statistical Equation for Habitables" or SEH. His proof is based on the Central Limit Theorem (CLT) of Statistics, stating that the sum of any number of independent random variables, each of which may be arbitrarily distributed, approaches a Gaussian (ie normal) random variable (Lyapunov form of the CLT). Dr. Maccone will then discuss the implications of this derivation, including a practical example of how the equation can be used to find the average distance between Habitables. Finally, this result will in turn be used to discover the statistical extension of the Fermi Paradox, namely the Fermi paradox re-read in terms of probability distributions.

Potentially Habitable Planet Discovered Date- 6th Oct 10 Source- carnegiescience.edu ' Washington, DC Astronomers have found a new, potentially habitable Earth-sized planet. It is one of two new planets discovered around the star Gliese 581, some 20 light years away. The planet, Gliese 581g, is located in a "habitable zone"—a distance from the star where the planet receives just the right amount of stellar energy to maintain liquid water at or near the planet's surface. The 11- year study, published in the Astrophysical Journal and posted online at , suggests that the fraction of stars in the Milky Way harboring potentially habitable planets could be greater than previously thought—as much as a few tens of percent.

New planet discovered named Super Earth - habitable for life Whispers that the Milky Way is filled with planets have turned into a roar. Earlier this week, astronomers announced the discovery of 600 more exoplanet candidates, including one "super-Earth" which may be habitable. The news strengthens many astronomers' suspicions that habitable planets are common and that more exciting discoveries are likely as better telescopes become available. Called a super-Earth because it is only 3.6 times more massive than Earth and possibly rocky rather than gaseous, it resides in a 58-day orbit on the inner edge of its orange star's habitable zone. If protected by a thick, cloudy atmosphere, it could have liquid water on its surface. Called HD 85512b, the exoplanet is only the second small world to be found inside a habitable zone and lies just 36 light years away in the constellation of Vela. That is close enough for future telescopes to scour it for signs of life. Planet-hunters announced their latest finds this week at the Extreme Solar Systems II conference in Moran, Wyoming. A ground-based telescope in Chile discovered 55 of these planets, including HD 85512b, using an instrument called the High Accuracy Radial Velocity Planets Searcher (HARPS). NASA's Kepler space telescope spotted the others, mostly much further away. While the HARPS team monitors nearby stars for telltale wobbles caused by orbiting planets, Kepler scientists search a wide field of faraway stars, watching for planets that become silhouetted against their suns.

Space Telescopes and the Hunt for Habitable Planets Complete video at: fora.tv Ian Morison describes new planet-detecting astronomical techniques such as "giant occulting screens" and groups of infrared satellite telescopes. Astronomers plan to use these techniques to detect life-supporting atmospheres on other planets. ----- Professor Ian Morison discusses one of the hottest topics in astronomy: detecting other solar systems. The methods by which this has been achieved so far have yet to detect an earth-like planet, but already a miniature version of our solar system has been discovered. How do these discoveries affect the prospects for life elsewhere? - Gresham College Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester. Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom. At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory's website.
NASA's Kepler Mission Finds Earth-size Planet Candidates in Habitable Zone, Six Planet System NASA's Kepler mission has discovered its first Earth-size planet candidates and its first candidates in the habitable zone, a region where liquid water could exist on a planet's surface. Five of the potential planets are near Earth-size and orbit in the habitable zone of smaller, cooler stars than our sun. Kepler also found six confirmed planets orbiting a sun-like star, Kepler-11. This is the largest group of transiting planets orbiting a single star yet discovered outside our solar system. Located approximately 2000 light years from Earth, Kepler-11 is the most tightly packed planetary system yet discovered. All six of its confirmed planets have orbits smaller than Venus, and five of the six have orbits smaller than Mercury's. For more information about the Kepler Mission, please visit www.nasa.gov

Astronomers find first habitable planet outside solar system SAN JOSE, Calif. — Astronomers have discovered the first planet outside the solar system with the potential to support life. The planet orbits a red dwarf star called Gliese 581, 20 light years from Earth, in the middle of the star's habitable zone, meaning that temperatures on its surface are just right for life to develop. US-based scientists found the planet using precise measurements from the Keck telelscope in Hawaii, which has been scrutinising Gliese 581 for more than a decade. The new planet, called Gliese 581g, is one of several known to be orbiting the star, but is the first to be discovered in the so-called Goldilocks Zone, where the distance from the star means that temperatures are neither too hot or too cold for life to exist. "We had planets on both sides of the habitable zone - one too hot and one too cold - and now we have one in the middle that's just right," Steven Vogt of University of California, who worked on the team that discovered the planet, said. He says that less than 500 planets have been discovered outside of the solar system, and the fact that this one lies in the middle of the Goldilocks Zone suggests that habitable planets could be extremely common. "The fact that we were able to detect this planet so quickly and so nearby tells us that planets like this must be really common," he said. "If the local stellar neighborhood is a representative sample of the galaxy as a whole, our Milky Way could be teeming with ...
The continuously habitable zone: Earth's life sustainability Amendment: 'Hot Jupiters' are thought to have "formed farther out and migrated inward via gravitational torques with a massive gas disk (Lin et al., 1996)" (Lin, Bodenheimer, & Richardson, 1996, p. 256). Since "roughly one-third of the giant planets discovered to date outside the Solar System have orbits within 0.5 astronomical units (AU) of their central stars (exoplanets(dot)org)" (Lin, Bodenheimer, & Richardson, 1996, p. 256), then I should note that whatever the likelihood is of terrestrial planets forming is, there may be roughly a 1 in 3 chance that their formation will be disrupted by a hot Jupiter moving in. However, I should also note that "if a giant planet forms and migrates quickly, the planetesimal population has time to re-generate in the lifetime of the disk and terrestrial planets may form (Armitage (2003)" (Lin, Bodenheimer, & Richardson, 1996, p. 256). And in some cases, it seems that "potentially habitable planets with orbits in the habitable zone and substantial water contents can form in such conditions," and that their obliquity "would likely be stable over long timescales (Atobe et al., 2004)" (Lin, Bodenheimer, & Richardson, 1996, p. 262). All in all, my argument is not significantly affected, since, even with the adjustment, we are still dealing with hundreds of billions of stars in our galaxy and tens of ***tillions of stars in the observable universe. Raymond, SN, Quinn, T. & Lunine, JI (2005). The formation and habitability of terrestrial ...
Kepler - A Search for Habitable Planets "Kepler is a critical component in NASA's broader efforts to ultimately find and study planets where Earth-like conditions may be present," said Jon Morse, the Astrophysics Division director at NASA Headquarters in Washington. "The planetary census Kepler takes will be very important for understanding the frequency of Earth-size planets in our galaxy and planning future missions that directly detect and characterize such worlds around nearby stars." The mission will spend three and a half years surveying more than 100000 sun-like stars in the Cygnus-Lyra region of our Milky Way galaxy. It is expected to find hundreds of planets the size of Earth and larger at various distances from their stars. If Earth-size planets are common in the habitable zone, Kepler could find dozens; if those planets are rare, Kepler might find none. In the end, the mission will be our first step toward answering a question posed by the ancient Greeks: are there other worlds like ours or are we alone?

40th anniversary of Hendrix death - "Hendrix Suite" dedication unveiled at his last known address 18th September marks 40 years since the death of guitar legend, Jimi Hendrix. To commemorate the anniversary London's The Cumberland hotel, Hendrix's last known address, has unveiled a Hendrix suite, designed to pay homage to the rock star's trademark psychedelic style (Friday September 2010). The opening commemorates the hotel's long association with Hendrix. He was a regular visitor to the property, just off Park Lane, during his frequent trips to London and held a fifth floor suite there during September 1970. His last known interview was with former NME journalist Keith Altham at the hotel, and Altham has since taken an active role in creating the suite to honour Hendrix.

Alien Planets & Eyeball Earths: The Search for Habitable Planets Find out, in 1080p, where to look for Extraterrestrial Life. What planets are likely to have the right conditions? And what makes Earth special? So far, in this age of planet hunting, we've yet to find anything like our solar system... with rocky inner planets in neat circular orbits, and evenly spaced gas giants on the periphery. Instead, astronomers have glimpsed a diverse planetary zoo, with giant planets in wide orbits around their parent stars, others that swing in so close they leave a comet-like tail, or molten rocky worlds emblazoned with oceans of lava. These finds have added new complexity to theories of how solar systems emerge in the birth of a star. As dust and gas swirl into the newborn star, they form a proto-planetary disk. Within this Frisbee-like structure, gravity sculpts planetary bodies that grow in size, sweeping up smaller bodies that form around them. Current theory holds that giant planets, forming on the periphery, commonly migrate into the inner solar system. This confirms the observation of so-called hot Jupiters orbiting perilously close to their parent stars. But these giants may clear out smaller rocky planets that form close to the star, creating a planetary desert... just where you'd hope to find life. Does that make the search for another Earth a wild goose chase? To find out, a group of planet hunters, using the Keck Telescope in Hawaii, examined a sample of 166 sun-like stars within 80 light years of Earth. To their surprise, they found ...
Kepler Detects Potential 'Habitable Zone' Planets Feb. 2, 2011 A NASA telescope has detected signs of more than 1200 possible planets outside of our solar system, and dozens of them are in the "habitable zone" around their stars where life might exist. "Kepler has blown the lid off of everything that we know about extrasolar planets." - Debra Fischer, professor of astronomy, Yale University The Kepler space telescope was launched in 2009 to find planets similar to Earth — rocky, potentially habitable alien worlds. Since then, the telescope has been staring at more than 150000 stars in one small patch of sky. It's looking for the slight dimming in the brightness of stars that could be caused by a passing planet. At a news conference, William Borucki, the mission's principal investigator at NASA's Ames Research Center, said that in its first four months of operation, Kepler has found an amazing number of events that could mean a planet is circling a star: 1235 possible planets. The amount of dimming reveals the planet's size, and Borucki says these possible planets come in all sizes.
First Habitable Planet Beyond Earth "The significance of this discovery is that it's the first time we found a planet that has the right mass and has the right distance to have liquid water and a substantial atmosphere. People have been getting closer and closer over the last couple of years; didn't find any planets that are on hot edge of the habitable zone and on the cold edge of the habitable zone, but finally we have one right in the middle."
Habitable Planets - Monika Kress (SETI Talks) SETI Talks Archive: Habitable planets must not only reside in a narrow range of distances from their stars, but they also must contain water and carbon. This is easier said than done. In this talk, Dr. Kress will discuss the chemistry in protoplanetary disks, and the physical processes by which earth-like planets form. In particular, Dr. Kress will focus on how habitable planets obtain carbon and water, the key ingredients for life.

News Update- New Habitable Planet Discovered 9-30 Scientists have discovered six planets near a red dwarf star called Gliese 581, one of which is potentially habitable, reports io9.com Thursday. The six planets are orbiting the red dwarf star and the one potentially habitable planet, Gliese 581g, is "tidally locked" so one of its sides is always facing the sun, while the other is always facing darkness. The planet, found by astronomers at the University of California, Santa Cruz, and the Carnegie Institution of Washington, is orbiting in the middle of the "habitable zone" of the red dwarf star Gliese 581, which means it could have water on its surface. Liquid water and an atmosphere are necessary for a planet to possibly sustain life, even though, according to scientists, it might not be a great place to live. Steven Vogt, a professor of astronomy and astrophysics at UC Santa Cruz and one of the leaders of the team, said "This is the first really solid discovery of a potentially habitable planet. The fact that we were able to detect this planet so quickly and so nearby tells us that planets like this must be really common."

Astronomers Find First Earth-like Planet in Habitable Zone Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope, a team of Swiss, French and Portuguese scientists discovered a super-Earth about 5 times the mass of the Earth that orbits a red dwarf, already known to harbour a Neptune-mass planet. The astronomers have also strong evidence for the presence of a third planet with a mass about 8 Earth masses. Copyright ESO
Exploring Mars for Evidence of Habitable Environments and Life By David Des Marais, staff scientist at NASA Ames Research Center Hosted at MSU on May 5, 2010 by the Astrobiology Biogeocatalysis Research Institute, Thermal Biology Institute and NSF Montana EPSCoR Dave Des Marais of NASA's Ames Research Center discusses why researchers believe that habitable environments probably existed on Mars more than 3 billion years ago. The Opportunity rover found evidence of saline lakes and groundwater on Mars, while the Spirit rover discovered rocks altered by liquid water and pure silica formed by hydrothermal activity. Orbiters have discovered widespread additional mineralogical evidence of ancient watery environments.
Stellar Simulations: searching for habitable planets Google Tech talks July 30, 2007 ABSTRACT Looking for a nice extra-solar vacation spot but worried about being downwind from a gas giant? Before booking your next interstellar flight, come check out how Sean Raymond's stellar simulations are being used in the search for habitable planets. Many of the 240 extra-solar planets that have been discovered so far are "hot Jupiters" -- gas giants orbiting very close to their host stars. Sean's work has shown that when these hot Jupiters form far from their host stars and migrate inward, they leave conditions in their wake favorable for the formation of a wide diversity of habitable planets, from small dry worlds to massive ocean-covered planets. In...
Discovery of New Potentially Habitable Planet - Gliese 581g In this clip Steven Vogt discusses his team's discovery of the new exoplanet Gliese 581g . -- Possible earthlike planet found in the Goldilocks zone of a nearby star! Gliese 581g, as the new planet is called, is in the zone where the temperature is just right. And with a mass of just three times that of the Earth, it's unlikely to be a gas giant. "Personally, given the ubiquity and propensity of life to flourish wherever it can, I would say, my own personal feeling is that the chances of life on this planet are 100 percent," said Steven Vogt, a professor of astronomy and astrophysics at the University of California, Santa Cruz, during a press briefing today. "I have almost no doubt about it." His colleague, Paul Butler of the Carnegie Institution of Washington, in Washington, DC, wasn't willing to put a number on the odds of life, though he admitted he's optimistic. "It's both an incremental and monumental discovery," Sara Seager, an astrophysicist at the Massachusetts Institute of Technology, told . Incremental because the method used to find Gliese 581g already has found several planets (all super-Earths, more massive than our own world) outside their stars' habitable zone, along with non-Earth-like planets within the habitable zone.
