yay possible aliens? 

There's a real possibility the alien megastructure called a Dyson swarm was created by intelligent life. 

Three months ago, news broke that a giant "alien megastructure" could exist around a bizarre-looking star 1,500 light-years away.

While the prospect of aliens was first launched by Penn State astronomer Jason Wright, almost everyone in the astronomy community agreed that the chances that this was the case were "very low."

Now, the latest investigations into this strange star by Louisiana State University astronomer Bradley Schaefer have reignited the alien theory, New Scientist reported.

What makes this star, KIC8462852, so bizarre is the drastic changes in light we see from it over time. Many stars experience temporary fluctuations in brightness, increasing and decreasing in luminosity over time, but KIC8462852's changes are severe by comparison.

Between 2009 and 2013, astronomers using the Kepler space telescope discovered that it would sometimes lose up to 20% of its brightness. What's more, the changes didn't follow any obvious pattern.

That would suggest something gigantic must be blocking the light at random times, meaning that it couldn't be a planet or other regular orbiting object because that would generate a distinct pattern of dimming light. It must be something that changes shape over time, thereby blocking different levels of light at random intervals.
