NASA Concludes That Comets, Not Alien Megastructures Orbit KIC 8462852 (examiner.com)

MarkWhittington writes: Back in October, findings from the Kepler Space Telescope suggested that something strange was going on around a star called KIC 8462852. Kepler was built to detect exoplanets by measuring the cycles of dimming light from other stars, indicating that a large object was passing between them and Earth. But the dimming light cycle from KIC 8462852 seemed to suggest a lot of smaller objects swarming around it. Scientists narrowed down the explanations to either a swarm of comets or alien megastructures. NASA announced evidence garnered by two other telescopes that pointed to the comet explanation.

  41. Chain of gas giants by Crowd+Computing · · Score: 1

    I wished I had been a little more calm when I wrote it. I concentrated too much on the lack of IR "glowing" observed and while its still not entirely accurate to say cometary dust doesn't put off infrared the main reason to be skeptical of the comet swarm hypothesis is that we just have no other examples of either such a large "swarm" of comets OR of any naturally occurring celectial body that blocks 22% of starlight. The largest gas giant planet would maybe obscure 2%.

    So the only thing really ruled out is diffuse dust. Why not a chain of gas giants in orbital resonance that periodically brings the planet in staggered alignment when viewed from Earth? If such a star system were closer, the gas giants would collectively then appear as a thick band on the stellar equator rather than as a single black dot. I'm not an astrophysicist, so I have no idea how much planetary mass a star can pull.

  45. A system like this might be super-habitable for us by Dr.+Spork · · Score: 2

    I think it's amazing that there could be a system with enough comets to block out such a big portion of starlight. It gets my imagination going because when I picture the future of human expansion, I don't see us living on the natural surfaces of planets, putting up with all the ways in which they are ill-suited to our comfort (wrong gravity, wrong color starlight, wrong day/night cycle for our circadian rhythm, wrong atmosphere, wrong temperature range, too much radiation, etc.). I know that people want to address some of these problems with some sort of transforming, and that will make sense on some planets, but most stars will not have eligible ones.

    However, most stars will have enough ordinary junk in their orbit that we will be able to manufacture (with self-replicating AI machines) a perfectly awesome and huge spinning habitat that could have a habitable surface area comparable to that of the Earth. The easiest source for the materials for such a habitat are smallish rocks, because it takes so little energy to eject habitat material from a quarry on a rock with such a small gravity well. A colony would simply dispatch an AI-controlled factory that would convert asteroid material into duplicate AI factories, plus fuel and thrusters that get these to other asteroids. Then the factories retool to convert the asteroids into parts for a giant spinning space station, in which the interior light, atmosphere, gravity and temperature are optimized for terrestrial life, while the star-facing exterior is covered with solar panels, and the shady side is a spiky forest of heatsinks. If the orbit is close enough to the star, the panels alone should generate enough energy to power all the systems and more.

    It's very 1960's thinking to picture ourselves living on the surfaces of other planets, and yet, even many scientists have not gotten past that obsolete picture. AI technology plus robotics will allow us to thrive even in extrasolar systems that have nothing but perfectly ordinary crap floating in orbit, because perfectly ordinary crap is exactly what we and every important feature of our biosphere are made of.

    What's exciting about a system like this is that if there are lots of comets, it means that there's a lot of great crap within arm's reach from which to build a gigantic new home.

    They think the first dimming event was caused by one comet.

    I think the thing to grasp might be that - as the illustration on the article shows, albeit with some artistic licence - you need to imagine looking at the star through the entire millions-of-kilometres length of a dusty comet tail (which streams directly away from the star, so directly towards us). That'll block a lot of light, I'm guessing.
