Do aliens exist? Astronomers are determined to find the truth behind that question.

Tabby's Star, known as KIC 8462852, is highly speculated to host a highly-advanced civilization that can build so-called "alien megastructures" around its orbit. It has seized the imagination of space-loving fans and astronomers for about a year. UC Berkeley's Breakthrough Listen initiative recently received USD 100 million from billionaire investor Yuri Milner, which should be good for 10 years.
