Tabby's Star, also known as KIC 8462852, exhibits unusual brightness fluctuations where its light suddenly drops and returns without a predictable pattern, unlike most stars that dim in consistent ways; this bizarre behavior led scientists to briefly speculate about alien megastructures before more natural explanations were investigated, though the mystery remains partially unsolved.

Why Does This Star Keep Disappearing?Added:
One star behaved so strangely that aliens became a serious discussion. Most stars dim in predictable ways, but Tabby's [music] star doesn't. Sometimes it's light suddenly drops, then returns, then drops again. No pattern, no clear explanation. [music] The behavior was so unusual that alien mega-structures were briefly suggested.
Today, the mystery isn't solved, only less mysterious.
