Let’s face it: KIC 8462852 (also Tabby’s Star or Boyajian’s Star) is a weird star. Since its unusual light variations were discovered by citizen scientists using data of NASA’s Kepler space telescope in September 2015 many, many things have been written by professional and amateur astronomers, science communicators and “searchers of mysteries”, as an interesting hypothesis about its behavior was that it could be signs of activity associated with intelligent extraterrestrial life constructing a Dyson swarm. Of course, this just run wild in general media, and many astronomers since them have been asked by journalist to talk about “Mysterious Tabby’s Star”.

In particular, this theme soon captured the attention of some of my friends at the Instituto de Astrofísica de Canarias (IAC, Spain), as they weekly produce an amazing ~2h science communication podcast Coffee Break: Señal y Ruido (Signal to noise). I’m proud to participate in this podcast from…

    Tabby’s star is dimming again, and astronomers are excited

    For the last few years, a distant star in the constellation Cygnus, known officially as KIC 8462852 and unofficially as Tabby’s star or the WTF star, has intrigued astronomers due to its irregular but significant dimming. Astronomers have struggled to find a natural explanation for why the star dims so much, 20 percent, before returning to its regular brightness.

    Rings and asteroids may explain ‘alien megastructure’ star

    ‘the model predicts that another dip will appear in 2021 thanks to a second cloud of asteroids – which usually come in pairs. This forecast has excited the wider community because it will indicate that astronomers are on the right track if the star dims that year.’
