A strange, worm-like cloud that appeared over Alaska has sparked a social media frenzy and official law enforcement investigation. Conspiracy theories suggested everything from a UFO to a plane crash to a Russian missile attack. On the morning of Thursday, April 7th, people in and near Lazy Mountain, Alaska, noticed a bizarre cloud formation streaking across the sky.

So here's something you rarely get to see, a freaking rain bomb, or the technical term 'microburst'! I've never heard of that term either, but it's actually really a thing. Basically, it happens when hot, dry air rises and mixes with heavy rain-bearing clouds.
