    According to scientists, images from the SPECULOOS (‘Search for habitable Planets EClipsing ULtra-cOOl Stars) telescopes, located in Chile and the island of Tenerife, have indicated that a distant planet may harbor the necessary conditions for life. The planet LP 890-9c orbits the star, LP 890-9, which rests 100 light-years from Earth. 40% larger than Earth, LP 890-9c orbits LP 890-9 roughly every 8.5 days, which was confirmed by the MuSCAT3 instrument in Hawaii. Scientists believe that fact permits the supposition that the planet exists in the “habitable zone” around the star. “The habitable zone is a concept under which a...

    Five Out of Five Researchers Agree: Earth's Solar System Special By Sara Goudarzi Special to SPACE.com posted: 31 March 2005 NEW YORK -- Though researchers find more and more distant planets revolving around alien suns, the discoveries highlight that Earth and its solar system may be an exceptionally rare place indeed. That was the consensus here Wednesday evening among five planetary science experts who spoke at the 5th annual Isaac Asimov Memorial Panel Debate held at the American Museum of Natural History. Neil DeGrasse Tyson, the Frederick P. Rose Director of the Hayden Planetarium, moderated the informal discussion. At issue...

    Rare Jewel: Earth-like Planets May Be Very Rare Msgr. Charles Pope • February 28, 2016 • I have written a good bit over the years about what is known as the “Rare Earth” Hypothesis. A recent blog on discovermagazine.com ponders how high the odds are against the existence of another Earth-like planet. More on that in a moment. But first let’s review some of the basics of the Rare Earth Hypothesis.While most people, including most scientists, believe that there may be billions of inhabitable planets out there a capable of sustaining complex life, the Rare Earth Hypothesis suggests that...

    Habitable Planets With Earth-Like Biospheres May Be Much Rarer Than Thought TOPICS:AstrobiologyAstronomyAstrophysicsExoplanetRoyal Astronomical SocietyBy Royal Astronomical Society June 26, 2021A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet, which would enable complex biospheres of the type found on Earth. The study was recently published in the Monthly Notices of the Royal Astronomical Society.The number of confirmed planets in our own Milky Way galaxy now numbers into the thousands. However, planets that are...

    Astronomers may have, for the first time, detected a sunlike star erupting with a giant outburst 10 times larger than anything similar ever seen from our sun, a new study finds. The new results may shed light on the effects such powerful outbursts may have had on the early Earth when life was born, and could have on modern Earth and our societies, researchers said. Our sun often unleashes flares that can each pack as much energy as millions of hydrogen bombs exploding at the same time. Solar flares are often accompanied by giant bright tendrils of solar plasma known...

    If you ever find yourself at a cocktail party of astrophysicists and don't know what to say, try this: "But what about the angular momentum?" No matter what the topic of conversation, you'll be guaranteed to sound erudite. Nearly every field of astronomy, from galaxy formation to star formation, has an "angular momentum problem." Nothing in the cosmos ever seems to spin or orbit at the rate it should. The moon is no exception. It is the flywheel to end all flywheels; if its orbital angular momentum were transferred to Earth's axial rotation, our planet would come close to spinning ...

    Astrobiology ^ | Wednesday, December 23, 2015 | Keith Cooper
    In 1993, French astronomer Jacques Laskar ran a series of calculations indicating that the gravity of the Moon is vital to stabilizing the tilt of our planet. Earth's obliquity, as this tilt is technically known as, has huge repercussions for climate. Laskar argued that should Earth's obliquity wander over hundreds of thousands of years, it would cause environmental chaos by creating a climate too variable for complex life to develop in relative peace. So his argument goes, we should feel remarkably lucky to have such a large moon on our doorstep, as no other terrestrial planet in our solar system...
  • I learned something interesting about the moon and the earth + climate(vanity)

    01/16/2012 1:51:34 AM PST · by Ancient Drive · 48 replies · 1+ views
    I was watching this program about the moon and the important role it plays on stabilizing earth. One of the things it does is keep it from wobbling all over the place. It keeps the earth fairly balanced, but every now and then the planet tilts 5 degrees up or down causing massive climatic changes. The last tilt turned what we now know as the Sahara desert from a lush green forest with rivers into the pile of sand it is today. So I'm thinking ok.. we have these tilts every now and then let's not forget solar flares +...

    Goldilocks isn’t the only one who demanded everything to be “just right.” The Earth and its fellow seven planets also needed perfect conditions to form as observed, and those right conditions occur rarely, a new computer simulation shows. The new simulation, described in the Aug. 8 Science, is the first to trace from beginning to end how planetary systems form from an initial gas disk encircling a baby star. “The really striking result of the new model is how chaotic and even violent the average story of a planet’s birth is,” says Edward Thommes, an astrophysicist now at the University...
  • Are There Aliens Already on Earth?

    Conspiracy theorists will readily tell you that the U.S. military is hiding alien corpses in a secret facility in the Nevada desert. But paleontologist and University of Washington geology professor Peter Ward thinks that scientists should be looking for a different type of alien life on earth: alien microbes. Ward is the author of several popular books about astrobiology, including the controversial Rare Earth, co-authored with Donald Brownlee. In his latest book, Life as We Do Not Know It, Ward addresses an issue often avoided by astrobiologists. Although all known life on Earth has a similar DNA-based chemistry, life found...

    University of Washington ^ | 1/13/2006 | Vince Stricherz
    In its 4.5 billion years, Earth has evolved from its hot, violent birth to the celebrated watery blue planet that stands out in pictures from space. But in a new book, two noted University of Washington astrobiologists say the planet already has begun the long process of devolving into a burned-out cinder, eventually to be swallowed by the sun. By their reckoning, Earth's "day in the sun" has reached 4:30 a.m., corresponding to its 4.5 billion-year age. By 5 a.m., the 1 billion-year reign of animals and plants will come to an end. At 8 a.m. the oceans will vaporize....

    Ever wondered how life began and whether there is life on other planets? You're not alone, but the curiosity rarely turns into a career. The UW astrobiology program gives hope to would-be professional stargazers. Astrobiology -- the study of life in the universe -- looks for scientific answers to questions like "How did life begin on this planet?" and "Are we alone in the universe?" The field builds on knowledge across several disciplines. UW biology professor Peter Ward and UW astronomy professor Donald Brownlee believe discovering intelligent aliens on other planets is unlikely. In Rare Earth, a book the two...

    Our solar system may be unique after all, despite the discovery of at least 120 other systems with planets, astronomers said on Wednesday. All the other solar systems that have been found have big, gassy planets circling too close to their stars to allow them to be anything like Earth or its fellow planets, the British and U.S.-based researchers said. If that is the case, Earth-like planets will be very rare, the astronomers write in the latest issue of the Monthly Notices of the Royal Astronomical Society. "Maybe these other extrasolar systems ... contain only the giant planets," said Mario...

Richards & Guillermo Gonzalez The American Spectator May 1, 2004 The American taxpayers recently footed the bill for a risky $800 million NASA mission. The good news? It worked. In January, two NASA landers bounced to their destinations and released their rovers Spirit and Opportunity to prowl the Martian landscape. These remarkable little robots were not searching for archaeological ruins or strange, black monoliths but something much less exotic--the fingerprints of water in liquid form....

    Imagine the blue marble of Earth turning white, as the glaciers advance, sea levels drop, harbors turn to meadows, and "snouts of ice" a third of a mile high bulldoze the skyscrapers of Manhattan. Scientists have been saying for some time that Earth is doomed, that the dying sun will balloon out and embrace the planet in the ultimate global warming -- but the incineration is at least 7 billion years away, and first, it's going to get very, very cold. At least two scientists have concluded that the Earth is already on the downward slope, its biological heyday millions...

    Earth-like worlds circling stars in orbital zones suitable for life may be few and far between in the cosmos, according to new research. In the first comprehensive study of extrasolar planetary systems, astronomers have shown that in most of them it would not be possible to keep an Earth-like world in orbit around a star so that it was neither too hot nor too cold for life. In general, other planetary systems fall into two types: those with Jupiter-like worlds circling close to their parent star, and those with more distant Jupiters in elliptical orbits. In both systems, maintaining an...

Don't bet on it, says New Mexico State University physicist Slava Solomatov. The more scientists learn about the conditions that make life possible on Earth, the more they realize how complex those factors are -- and how a relatively small change in one condition or another could have rendered the planet uninhabitable, Solomatov said. "It's a very finely tuned system," he said. "Some of the factors are well known, but we ...

    In the scientific community, there is still a great deal of energy devoted to “listening” for evidence or hints of intelligent, extraterrestrial civilizations out among the stars. Most of you are probably familiar with the Search for Extraterrestrial Intelligence (SETI) and their decades of work in this field. They’re still at it and, in fact, are upping their game with a new generation of laser sensors. These projects drew fresh attention after the discovery of Tabby’s Star and the frantic speculation over whether or not some ancient civilization had built a Dyson Sphere around their own sun. This has led...
