Tantalising Tabby's Star teases watchers with big dimming event

No 'alien' megastructure, but lots of ongoing weirdness

In January, boffins decided they'd settled the mystery of "Tabby's Star", the far-off star that dimmed so rapidly it almost looked like something, or someone, was responsible. Scientists have since shrugged off the idea the dimming is caused by an "alien megastructure". Instead, they suggest there's just a lot of dust surrounding the star, which makes for many odd moments."
