A breakthrough in the search for extraterrestrial intelligence | Human World | EarthSky

The researchers called their new analytical technique “a milestone in SETI.” One researcher commented: “We now know that fewer than one in 1,600 stars closer than about 330 light years host transmitters just a few times more powerful than the strongest radar we have here on Earth.”

Researchers Find Extraterrestrial Amino Acids in Antarctic Meteorite | Astrobiology, Planetary

A team of astrobiologists from NASA's Goddard Space Flight Center and the Carnegie Institution for Science has found a wide diversity of amino acids in Asuka 12236 , a carbonaceous chondrite meteorite recovered from the Nansen Ice Field in Antarctica by Belgium and Japan researchers in 2012.

This SEM image shows a polished thin section of Asuka 12236. The section is about 1 cm (a third of an inch) across. Most of the bright grains in the image are iron-nickel-metal and/or iron-sulfide. The gray is mostly silicate, with the darker gray areas more magnesium-rich, while the lighter gray areas are more iron-rich. The roundish objects, and some fragments of them, that tend to contain most of the small, bright metal grains are called chondrules, which formed as molten droplets.

Want to Talk to Aliens? Try Changing the Technological Channel Beyond Radio - Scientific American

The endeavor known as the search for extraterrestrial intelligence (SETI) has long relied on radio telescopes to listen for broadcasts from potential alien callers. Yet in an expansive galaxy such as ours, how can we ever be sure that we have tuned in to the right station?

Along with providing fodder for imaginative scenarios—we flip the switch on some new listening device and, voilà, receive a transmission from E.T.—the results might encourage would-be alien hunters to innovate. Research efforts dedicated to discovering and developing new methods to communicate across cosmic distances may ultimately offer greater chances of making contact than long programs using a single technology.

Revisiting the Drake Equation - a cultural addendum - Room: The Space Journal

In a collection of fantastical stories about a far-away land full of peculiar and mystical beings, children's author L Frank Baum wrote about a land called Oz which was ruled by a powerful and just fairy-child known as Ozma. In 1960, inspired by Baum's work, scientists working with Project Ozma used the National Radio Astronomy Observatory's 85-foot radio telescope to detect interstellar radio waves.

This groundbreaking SETI (Search for Extraterrestrial Intelligence) experiment was launched by Frank Drake, who created the eponymous Drake Equation in 1961. The radio astronomer would go on to play an important role in developing the 1974 Arecibo Message, the most powerful radio broadcast ever deliberately beamed into space.

Does the Sun have a long-lost twin? | The Week UK

Our Sun may have a twin, according to astrophysicists at Harvard University. Avi Loeb and collaborator Amir Siraj have suggested that a second star must have helped the sun collect passing debris because the Sun's gravity alone wouldn't have been powerful enough to pull so many objects into its orbit. They believe the twin broke away and has ended up in a completely different area of space.

A UFO expert is encouraging "extraterrestrial actors" to audition for alien parts in his new plays. John Steiger, 61, said alien actors would "have to audition just like everyone else" and warned that "they're going to have a tough time winning any role". However, he is not expecting an avalanche of applications. "I fear though that my plays are not at the top of the list of alien concerns about human activities here on Earth," he said.

Game of Thrones creators to bring Liu Cixin's sci-fi trilogy to Netflix | Television | The

Netflix's Peter Friedlander described the books as having "changed what science fiction meant to me for ever", saying: "[Cixin's] ability to interweave science with fiction made his vision of the future and extraterrestrial contact feel more realistic than any other science fiction I've read. I was also drawn in by the story of all of humanity [being] vulnerable to the same external threat and how this both unifies and divides humans."

The Three-Body Problem, which won the Hugo award for fantasy fiction in 2015, and its follow-ups are international bestsellers; fans include Barack Obama, Elon Musk and Mark Zuckerberg. The first Chinese science-fiction novel to be translated into English, its success has been credited with sparking a new wave of Chinese fantasy writing.
