At least 7 stars in our galaxy have the potential to harbor advanced alien technology, researchers find

• Researchers found seven stars in our galaxy that might host alien megastructures called Dyson spheres.
• But these stars' strange behavior could also be explained by other phenomena, like clouds of dust.
• They'll need much more evidence to confirm that Dyson spheres truly surround these stars. 

In the search for intelligent alien life, finding a Dyson sphere would be like hitting the jackpot.
