Explanations

The researchers then wondered if KIC 8462852 was the only star in the Kepler data behaving in this strange way. To find out, they constructed an algorithm to search for similar extreme dips in the star’s brightness. They found over a thousand of them, but the rest turned out to be either binary systems undergoing eclipses, sunspot activity, or errors in the Kepler instrument itself. When they’d reviewed all the candidates, not a single other star had the same behavior.

That means it’s likely not a common phenomenon. So what is it? The main problem is that, while there is periodicity within the dimming pattern, the full, overall pattern is not periodic. Multiple events that aren’t periodic are hard to create a model for. But the researchers evaluated as many possibilities as they could think of. These are:

Instrument or data errors: The first possibility the researchers discuss is that the dimmings are caused by the instrument itself, just like a smudge on your camera lens can produce an image that looks like a UFO. To rule out these glitches, they applied data analysis algorithms, checked to make sure no cosmic ray events were recorded at the same times as the dips (as those can sometimes cause errors in electronic devices), looked at the light from neighboring sources recorded by Kepler to see if those displayed the same patterns (they didn’t), and more. At the end of this analysis, the researchers concluded that the pattern Kepler’s seeing is not a technical problem—it’s a real astrophysical event.
Variable stars: Some stars see their brightness vary naturally. But KIC 8462852 doesn’t match the characteristics of most known variables. There is, however, one type that could almost fit the bill and could even explain some of the weirdness in KIC 8462852’s graph. These are Be stars, and they’re spinning so fast they’re essentially breaking up, ejecting material every so often. This is often seen as a bright emission, but sometimes it can cause dimming. But Be stars produce excess infra-red light, which isn’t the case here; the star's temperature is also wrong, among other issues. Close, but no pez.
Dust getting in the way: Another possibility is clumps of dust loosely orbiting the star, periodically obscuring it. While there’s no way to rule this one out, the researchers “disfavor” it, because KIC 8462852 doesn’t seem to be a young star, and older stars don’t tend to maintain these sorts of dusty disks (they tend to condense into planets).
Debris getting in the way: It’s possible that the system has an equivalent (but far more dense) version of our asteroid field. If so, maybe some of that material is getting in the way. Alternatively, objects like broken up comets or debris from planetary collisions could cause dimmings. This one is actually something of a promising possibility, so the researchers discuss it in more detail.

tak už se to blíží :D

The star's large changes in brightness is consistent with a large mass (or many small masses together) orbiting the star in "tight formation".[2] Numerous hypotheses exist to explain the star's unusual light profile. Researchers currently think the most likely explanation for the star's odd reduction in light is due to a large dust cloud of broken up comets orbiting the star elliptically.

However, the star received intense media attention in October 2015 over speculation that its unusual light output could be signs of unnatural activity indicative of intelligent extraterrestrial life.

Jinymi slovy idioti novinari.. Neco jako kdyz resili ze nekdo z budoucnosti poskozuje CERN. co na to rict.. chtej holt cteny noviny.. BTW, vic nez polovina americanu si mysli, ze film Martan byl natocen podle skutecnych udalosti...

Myslim, ze se to sem docela hodi. Necetl jsem nic blizsiho, ale neni to se zdrojem na ac24 ;)

BYDK: jak slozitejsi? muzes myslenku rozvest nebo se dockame jen nejakeho linku na youtube videjko?


JIKE: fanousci vetrelce si natocili videjko a snazej se posbirat reklamni hity na youtube. cetl jsem, ze prej se v soucasnosti dost lidi zivi dobre tim, ze chrli na jutub videjka, lidi je lajkuji a pak za reklamu dostavaji autori penize... :P
