Are There Signals Coming from Deep Space?

Are There Signals Coming from Deep Space

     The star KIC 8462852 may have an unpronounceable name, but just about everyone with an interest in aliens has been talking about it. As of today, they can elaborate their discourse with some new results.

The conversations started about three weeks ago, when a paper written by a small battalion of astronomers pointed out that this star – an imposing 1400 light-years from where you’re sitting – occasionally dips its headlights. Every few weeks or months, it will blink, temporarily dimming to as little as 80 percent of its normal brightness. There is no indication (and little likelihood) that this bizarre behavior is caused by planets orbiting the star. Even Jupiter-size worlds would only block about one percent of the star’s light.

So what is going on? The astronomers who discovered this strange behavior considered several possible explanations for the dimming. Their favorite was the presence of cometary debris in orbit around the star – an idea they liked, but didn’t love.

However others – and especially the press – were jumping on another, sexier bandwagon. The occasional dimming of KIC 8462852 might be due to “megastructures” – giant astroengineering projects that aliens had undertaken in their solar system. These could be space habitats or phalanxes of orbiting solar energy collectors (so-called Dyson swarms, named after the physicist who popularized the idea). They might even be giant, opaque “cut outs” whose blockage of starlight would be a beacon to other worlds, indicating that KIC 8462852 was an oasis of intelligence in the galactic desert.

All nice ideas. Exciting ideas. But how would you prove any of them? […]

One of the most renowned figures in science discusses extraterrestrial life, artificial intelligence, and the future of computer technology

     A bizarre space anomaly detected by the Kepler Spacecraft has caught the attention of SETI (Search for Extraterrestrial Intelligence). The institute recently pointed the Allen Telescope Array system 300 miles northeast of San Francisco at the star, KIC 8462852, to test the hypothesis that the anomaly may be a signature of an extraterrestrial civilization.

“If this pans out it could be the biggest story since the invention of the wheel or the discovery of fire—it’s on that scale,” said Dr. Michio Kaku in a phone interview with the Observer. […]

      As NASA’s Dawn spacecraft gets closer to the dwarf planet Ceres in the asteroid belt, this bizarre body seems to yield more questions than answers. …

… In its latest video, posted Thursday, NASA shows us that in addition to the intriguing bright spots in a large crater on Ceres, there are also bright streaks running down the sides of a pyramid-shaped mountain rising higher than Alaska’s 20,000-foot (6,100 meter) Mt. McKinley. …

Scientists puzzled by strange lights on dwarf planet Ceres

Scientists are perplexed by a pair of strange lights on the surface of Ceres–a dwarf planet in the asteroid belt between Mars and Jupiter.

NASA’s Dawn spacecraft photographed Ceres on February 19 from a distance of approximately 29,000 miles. Although regions of higher-than-average reflectiveness have been seen on Ceres before, these new photos from Dawn show two bright spots within the same basin on the dwarf planet’s surface.

“The brightest spot continues to be too small to resolve with our camera, but despite its size it is brighter than anything else on Ceres. This is truly unexpected and still a mystery to us,” said Andreas Nathues, lead investigator for the framing camera team at the Max Planck Institute for Solar System Research in Germany, in a recent NASA press release.

Although scientists are puzzled by these mystery lights, they aren’t without possible explanations. As Mashable describes, “The most obvious contender is ice, although ice would reflect more than 40% of all light hitting it. The difference may be accounted for by the resolution limit of Dawn’s camera at this distance. Scientists have previously detected water vapor coming from the surface of the dwarf planet, making ice — a more likely option.”

But Chris Russell, principal investigator for the Dawn mission, believes, “This may be pointing to a volcano-like origin of the spots, but we will have to wait for better resolution before we can make such geologic interpretations.”

NASA’s Dawn spacecraft will enter orbit around Ceres on March 6, and will continue collecting better photos of the dwarf planet and its mysteries during the next 16 months. With better photos, scientists will hopefully be able to better determine if the strange bright spots on Ceres are signs of an extraterrestrial civilization, or if they indeed have a volcanic origin.
