چیزی عظیم، با مساحت تقریباً 1000 برابر زمین، نوری را که از یک ستاره دور به نام KIC 8462852 می آید، مسدود می کند، و هیچ کس کاملاً مطمئن نیست که چیست.

The most mysterious star in the universe | Tabetha Boyajian TED 13:47

Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.
