Area 51 Fast Facts
Here's a look at Area 51, a highly classified United States Air Force facility located at Groom Lake in southern Nevada.
The US government's official name for Area 51 is the Nevada Test and Training Range, which is a unit of the Nellis Air Force Base. Today it is used as an open training range for the US Air Force
According to the CIA, the name Area 51 comes from its map designation. It was also previously referred to as "Paradise Ranch" in order to make the facility sound more attractive to those that would be working there. "Paradise Ranch" was then shortened to "the Ranch." Other nicknames include "Watertown" and "Dreamland."
In 1958, under Public Land Order 1662, the 38,400-acre land area was "withdrawn from public use by the US Atomic Energy Commission, a predecessor to the US Department of Energy."
It is located more than 120 miles northwest of Las Vegas.
It is restricted to the public and has armed guards patrolling the perimeter. It's also impossible to enter the airspace above without permission from air traffic control.
Area 51 has long been a topic of fascination for conspiracy theorists and paranormal enthusiasts who believe it to be the location where the US government stores and hides alien bodies and UFOs.
One popular UFO conspiracy is that in 1947 in Roswell, New Mexico, remains from a flying saucer that supposedly crashed were brought to the site for reverse engineering experiments in order to replicate the extraterrestrial spacecraft.
In June 2019, a poll conducted by YouGov found that 54% of US adults think it is likely the government knows more than it's telling about UFOs, 27% saying it is unlikely, and 19% saying they do not know.
