Wow! Signal
In 1977, astronomer Jerry Ehman used a radio signal detector to scan the stars around the constellation Sagittarius. Ehman picked up a 72-second radio frequency that appeared to be coming from deep space. He wrote "Wow!" in the margin of his computer printout, leading the bizarre sound—which is theorized to be aliens attempting contact—to be dubbed the Wow! Signal.
The Phoenix Lights
On March 13, 1997, the people of Phoenix, Arizona saw something that remains unexplained to this day. That night, bizarre lights appeared overhead in a V-formation that silently moved overhead and occasionally stopped to hover over one location. It was allegedly the size of several football fields. Even Kurt Russell admitted to having witnessed the strange phenomenon in real life.
