ANITA Anomaly
The Antarctic Impulsive Transient Antenna or ANITA has been getting a lot of important data for years. This is actually a high-altitude balloon that was designed specifically to detect ultra-high-energy neutrinos that come from outer space. It was launched in the Summer of 2006 and currently sits at 37,000 meters from the surface of the Earth. While the antenna is designed to detect things from outer space, it actually began to pick up a strange signal sometime in 2016 that seemed as if it was coming from beneath the ice in Antarctica. That started the wild adventure that made this one of the biggest cosmic mysteries today!
