Has the 40-year old mystery of the "Wow!" signal been solved? In August 1977, the Ohio State University Radio Observatory picked up a radio transmission from the Sagittarius constellation that was so strong it inspired the astronomer who discovered it to write "Wow!
" Why Would Aliens Even Bother with Earth? As an astrobiologist I spend a lot of my time working in the lab with samples from some of the most extreme places on Earth, investigating how life might survive on other worlds in our solar system and what signs of their existence we could detect.
If there is biology beyond the Earth, the vast majority of life in the Galaxy will be microbial—hardy single-celled life forms that tolerate a much greater range of conditions than more complex organisms can. To be honest, my own point of view is pretty pessimistic. Don’t get me wrong—if the Earth received an alien tweet tomorrow, or some other text message beamed at us by radio or laser pulse, then I’d be absolutely thrilled. So far, though, we’ve seen no convincing evidence of other civilizations among the stars in our skies. Theconversation. Ever since studies started suggesting that chemical reactions between water and rock on Saturn’s moon Enceladus could provide enough energy in the water to feed microbial life, scientists have been searching for proof that the right sort of reactions really do occur.
And during its last dive through the icy plumes that Enceladus erupts into space in October 2015, the Cassini spacecraft has finally managed to find it – in the form of molecular hydrogen. The finding, published in Science, means the moon can now be considered highly likely to be suitable to host microbial life. In fact, the results should undermine the last strong objection from those who argue it could not. Enceladus is a small (502km in diameter) moon with an icy surface, a rocky interior and an ocean of liquid water sandwiched between the two. Atmosphere found around Earth-like planet GJ 1132b. Image copyright DANA BERRY Scientists say they have detected an atmosphere around an Earth-like planet for the first time.
They have studied a world known as GJ 1132b, which is 1.4-times the size of our planet and lies 39 light years away. Their observations suggest that the "super-Earth" is cloaked in a thick layer of gases that are either water or methane or a mixture of both. Moon Temple: Art Project Probes Spiritual, Cultural Needs of Lunar Colony. European Space Agency (ESA) artist-in-residence Jorge Mañes Rubio has drawn up plans for a "moon temple" that would help meet the spiritual, social and psychological needs of lunar settlers.
Those needs will likely be considerable, given that the pioneers will be isolated from the rest of humanity on a world hostile to life as we know it, Rubio said. His vision involves building a dome on the edge of Shackleton Crater, which is 13 miles (21 kilometers) wide and 2.6 miles (4.2 km) deep. Shackleton is a prime candidate for a future lunar outpost, experts have said; the crater lies at the moon's south pole, and its permanently shadowed depths are thought to harbor large amounts of water ice. Could Fast Radio Bursts Be Powering Alien Probes?2017-09. These Seven Earth-Sized Exoplanets Have Everyone Freaking Out Over Alien Life. NASA develops supersensitive test to seek out life on ocean worlds. Life isn't just where you find it, but how you find it.
Because any extraterrestrial life in the Solar System may be very rare, NASA's Jet Propulsion Laboratory (JPL) in Pasadena is looking at a new technique that is 10,000 times more sensitive than the ones used in the current generations of deep space probes. Called capillary electrophoresis, it's especially well suited for seeking life in the buried oceans of Jupiter and Saturn's moons. The search for life in our Solar System is a major priority for NASA, but as we learn more about the nature of the other planets and moons, it's becoming apparent that if life does exist, it will be in the form of very simple, very rare microorganisms.
This May Be the Best Explanation Yet For That Mysterious ‘Alien Megastructure’ Cosmos on Nautilus: If aliens have killed themselves off, what hope is there for us? Are aliens really trying to contact us? This is the Milky Way in all its glory, as seen from Earth.
Does the Drake Equation Confirm There Is Intelligent Alien Life in the Galaxy? The Drake Equation, written by astrophysicist Frank Drake in 1961, is a probabilistic equation to come up with an estimate of the number of intelligent, technological civilizations that should be in the Milky Way—and by extension, the universe.
It is the foundation for a number of statistical models that suggest intelligent alien life should be widespread throughout the galaxy. Here is the equation: Advertisement - Continue Reading Below Here's the breakdown variable by variable: Of course, the values for most of these variables are extremely rough estimates and the subject of much debate. What we still struggle with is pinning down the probability that life will spring from organic compounds, a process known as abiogenesis, and the probability that basic microbial life will eventually evolve into an intelligent species. Alien ‘Wow!’ signal could be explained after almost 40 years. Way back in 1977 something amazing happened (apart from the release of Star Wars obviously).
Astronomer Jerry Ehman was using the Ohio State University’s Big Ear radio telescope to sweep the sky for possible signals from extraterrestrial civilisations. He found something. While pointing towards a grouping of stars called Chi Sagittarii on 15 August, he received a powerful blast of radio waves that lasted for 72 seconds. Alien life, or noise? Russian telescope detects 'strong signal' from sun-like star. As David Bowie might have sung: is there life on HD164595b?
A Russian radio telescope scanning the skies has observed “a strong signal” from a nearby star, HD164595, in the constellation Hercules. 'Twisty' Molecule Essential to Life Spotted in Deep Space For 1st Time. Molecules with "right-handed" and "left-handed" versions are essential to all life on Earth, and have been found in meteors and comets. Now, for the first time, one has been spotted in interstellar space. Aliens: Are We Looking in the Wrong Place? The $100 Million Hunt for Alien Life. If its first quarter is anything to go by, 2016 may be shaping up historically as the 1491 of space discovery. The month preceding Valentine's Day alone provided what would once have been a year's worth of cosmic news. Blue Origin, the aerospace company owned by Amazon CEO Jeff Bezos, took one giant leap toward a new Age of Discovery by relaunching and landing a rocket that had already made a round-trip journey through the stratosphere – a revolutionary moment in private space exploration.
A pair of researchers kicked off a frenzied planet hunt by demonstrating that a massive, heretofore undetected planet could be lurking on the outer edge of our solar system. Meanwhile, in a restricted swath of Appalachia where cell service and Wi-Fi are prohibited to minimize radio interference, a team of astrophysicists and programmers from UC-Berkeley inaugurated a new interstellar exploration at the Robert C.
Byrd telescope in Green Bank, West Virginia. Worden has a more optimistic explanation. Hunt for Intelligent Aliens Should Focus on 'Transit Zone' Scientists searching for signs of intelligent extraterrestrial life should put themselves in the aliens' shoes, a new study suggests. Researchers have identified and characterized many potentially habitable alien planets via the "transit method," which notes how parent stars' light changes when orbiting worlds cross these stars' faces from Earth's perspective.
(NASA's Kepler space telescope is the most famous and prolific instrument to use this technique.) Odd star’s dimming not aliens’ doing. Tabby’s star is an oddball. Branded as a home to an “alien megastructure,” it flickers and dims like an aging lightbulb. Twice, the star’s light plummeted by roughly 20 percent and then quickly rebounded. That was after the star steadily dimmed by about an additional 20 percent between 1890 and 1989, astronomer Brad Schaefer of Louisiana State University in Baton Rouge reports online January 13 at arXiv.org. “Twenty percent dimming is inexplicable,” says Schaefer, who discovered the century-long fading in a photograph archive at Harvard University. “Tabby’s star is doing something utterly unique.” Fungi survive on the ISS under Mars-like conditions. Results are back from one of the latest experiments hosted on the International Space Station (ISS), with researchers from Spain's National Institute of Aerospace Technology (INTA) using the facility to study how hardy fungi species, collected from the Antarctic, cope under simulated Martian conditions.
The results are helping scientists gain insights relevant to the search for life on the Red Planet. The ISS is a hotbed for insightful studies, hosting numerous experiments that significantly improve human understanding of the long-term effects of space flight. Previous work has looked at how quickly medicines degrade in space, how microgravity effects the human immune system, and much more. The new study centered on two species of fungi known as Cryomyces antarcticus and Cryomyces minteri. The wonders of deep space: Scientists are on the hunt for alien molecules. Another Nail in the Coffin: NASA Telescope Confirms "Strange Lights" Around Star Are Comets. 'Alien Megastructure' Mystery May Soon Be Solved. The mystery behind a strangely dimming star could soon be solved. Would We Recognize E.T. If We Saw It? The story behind 'alien megastructures' scientists may have found (but probably didn't) This is a tricky story to write.
The mysterious scientific observations it deals with could wind up being nothing, or they could amount to some new, interesting astrophysical phenomenon that gets its own little section in a planetary science textbook someday. The Most Mysterious Star in Our Galaxy. In the Northern hemisphere’s sky, hovering above the Milky Way, there are two constellations—Cygnus the swan, her wings outstretched in full flight, and Lyra, the harp that accompanied poetry in ancient Greece, from which we take our word “lyric.” Between these constellations sits an unusual star, invisible to the naked eye, but visible to the Kepler Space Telescope, which stared at it for more than four years, beginning in 2009. “We’d never seen anything like this star,” says Tabetha Boyajian, a postdoc at Yale. “It was really weird.
We thought it might be bad data or movement on the spacecraft, but everything checked out.” What Edward Snowden Got Wrong about Eavesdropping on Aliens. Edward Snowden, the former contractor who leaked National Security Agency secrets publicly in 2013, is now getting attention for an odd subject: aliens. In a podcast interview with astrophysicist Neil deGrasse Tyson, Snowden suggested that alien communications might be encrypted so well that humans trying to eavesdrop on extraterrestrials would have no idea they were hearing anything but noise. Alien Transit Systems May Be a Giveaway in the Search for ET. Avi Loeb has an unorthodox new idea about how to search for alien civilizations—and it is hardly a surprise. Loeb, who chairs the astronomy department at Harvard University, has spent much of his career thinking about how the first stars came to life after the big bang, and how galaxies were born. But lately he’s become intrigued with the search for extraterrestrial intelligence, or SETI, and he tends to come at it in unusual ways.
The Fermi Paradox (Pt. I, II) MIT study on exoplanet orbits may narrow parameters in search for life. A team of researchers from MIT and Aarhus University, Denmark, have discovered that Earth-sized exoplanets orbit their parent stars in the same way that our planet orbits our own Sun – maintaining a roughly equidistant circular orbit. NASA Chief Scientist Ellen Stofan Predicts We'll Find Signs Of Alien Life Within 10 Years. Ellen Stofan (NASA) [1503.07804] The Nature of Inhabited Planets and their Inhabitants.
