When astronomers turn to Twitter to ask everyone who has access to a big enough telescope to look at the sky, you know something is up. Indeed, something was up this past weekend, as one of the Universe's most mysterious stars reignited some baffling behavior.
Tabby's Star, also known as KIC 8462852, once again started the unusual pattern of dimming its lights, a behavior first observed in 2015.
Matt Mutterspaugh, like fellow astronomer Jason Wright from Penn State University, noticed the dip in KIC 8462852's light emissions this past weekend.
As early as Friday, he already observed that Tabby's Star had dimmed by three percent in just a couple of days.
Discovered in 2009, KIC 8462852 came to be known as Tabby's Star because a team of astronomers, led by Tabetha Boyajian from Yale University, noticed the unusual way its light dims. It's not uncommon for a stars' light to dim when planets orbiting around it pass in front of it relative to Earth.
Tabby's Star, however, didn't follow the usual pattern of such dips in light, suggesting no periodic orbiting of planets or other cosmic bodies.
Still Probably Not Aliens
Naturally, such a phenomenon tugged on the curiosity of astronomers, and a number of possible explanations have been suggested.
The most common, and perhaps popular among these - you guessed it - is that something alien is the cause. One astronomer thinks that a Dyson Sphere is causing the strange dips, thereby nicknaming Tabby's Star as the "alien megastructure" star.
However, as much as we'd (maybe) love to find aliens at the root of this strange obvservation, other astronomers have found, and are developing, other explanations.
Though, it doesn't hurt to be on the lookout.
Some think that comet swarms, debris from a devoured planet, or possibly even space dust floating around the star are causing the unusual light emissions.
Still, others suggest that it could all just be flawed data, which is why nothing conclusive has been said yet about Tabby's Star.
Simply, there wasn't enough data from two years ago to say anything definitively...

Now, there is now a lot more data to use, but it would take time for researchers to fully consider what the information could tell us about Tabby's Star.
It's also possible that the new data won't result in anything definitive, but it's worth a shot. Some data is better than no data at all.
At the very least, it'll help us to better understand curiosities in the cosmos like KIC 8462852.
