Sure, that's just what the aliens want you to think.
Radio telescopes have been picking up some unusual flashes in the sky that appear for just moments without repeating, and scientists haven't been able to figure out why. This is pretty worrisome, because unusual changes in radio signals from space is basically how every alien invasion movie ever made begins. Don't start welcoming our future overlords yet, though -- according to an article in this week's issue of Science, these flashes might be the final farewell greetings of a supramassive neutron star collapsing into a black hole. Weirdly, it's kind of nice to know that even dying stars do not go gently into that good night. Well, that and it's a huge relief that it's not invading aliens. I mean, that we know of yet.
