Kepler observed that the star KIC 8462852 underwent irregularly shaped, aperiodic dips in flux down to below the 20% level. The dipping activity can last for between 5 and 80 days. Some astronomers seem to think one of the most likely explanations is orbiting megastructures built by a super-powerful alien race near that star. http://www.theatlantic.com/science/archive/2015/10/the-most-interesting-star... http://arxiv.org/pdf/1509.03622v1.pdf http://sites.psu.edu/astrowright/ http://www2.astro.psu.edu/~jtwright/Dyson/GHAT4.pdf -- Warren D.
