Humans have seen unidentified flying objects (UFOs) in the skies since the beginning of civilization. The earliest sightings are documented in cave drawings or mentioned in stories and songs of many different cultures. These objects were seen by regular people, military personnel, and astronauts. What many people don’t realize is that some of the most enigmatic and baffling UFO sightings and encounters have taken place in space, experienced by astronauts of many nations. The following is a list of the most stunning space UFO sightings:

Apollo 10 – Music Heard on the Dark Side of the Moon

One of the most controversial incidents from the early days of America’s quest to land on the moon took place on Apollo 10. As the craft whizzed around the dark side of the moon, astronauts John Young and Eugene Cernan began to hear music and it seemed to be coming from the moon. Both the astronauts were concerned about telling NASA for fear of how they would be perceived. The conversation between the astronauts about what they heard was hidden for more than 40 years. During the conversation, the two Apollo 10 astronauts quiz each other on if they heard the music, what it sounded like, and where it was coming from.

They weren’t in radio contact with the Earth, yet they heard strange music seemingly coming through their instruments from the dark side of the moon. The music was eerie, to say the least. It sounding like an cosmic whistling. The astronauts didn’t know what to think. Was the music being played by alien beings, was it the natural hum of the universe, or were they cracking up? Cernan said they never paid much attention to it. They simply chalked it up to radio interference and thought it was so insignificant they never mentioned it to the other astronauts.

Now a NASA technician has stated the so-called ‘music’ was caused by the radios in the command module and the lunar module interfacing with each other. However, another astronaut, Al Worden, thinks there may be more to it than that. So the 40 year-old mystery of the music on the dark side of the moon rages on.

Cosmonauts Spot Strange ‘Clouds’

But Americans aren’t the only ones seeing strange goings on in the sky. An article published in 1992 in Spektra newspaper talked about an incident on August 25, 1978 where several cosmonauts reported seeing mesmerizing iridescent clouds that looked like swan’s wings and were blue, pearly-white, purple, violet, reddish, purple, and green. Called a magic spectacle, they were seen again in 1985. They remain unidentified and unexplained.

Cosmonauts Observe An Unidentified Sphere

Cosmonauts Strekalov and Gennady Manakov said in 1990 while on their way to the MIR space station they saw a beautiful, perfectly shaped sphere which was visible for 10 seconds, changed colors, then vanished. (Source: Rabochaya Tribuna newspaper, October 16, 1990 issue)

Cosmonauts Have Otherworldly Experience

This is an incredible story. Six cosmonauts on the Soviet Salyut-7 orbital station in 1984 saw a large, orange colored gas cloud suddenly appear. The Salyut-7 entered the cloud and it seemed to seep into the space station. It engulfed the crew, blinded them, and prevented them from communicating. A few seconds later their sight returned and they saw 7 smiling angels with large wings and blinding halos in the cloud floating away from their space station. When the cloud and the angels disappeared 10 minutes later, the crew reported feeling a devastating loss. A battery of tests showed the crew was of sound mind. (NLO magazine Issue 9, 1998)

Cosmonaut Hears ‘Space Whisper’

One former cosmonaut talked about he and his flight engineer hearing a ‘space whisper’ while aboard a Soviet spacecraft. He said he suddenly felt a presence next to them and became dumbfounded and mute. Then seemingly from inside themselves they heard someone whisper: “You arrived here too early, and you did it in a wrong fashion. Trust me, for I am your ancestor on the maternal side. Do you remember, she told you; back when you were a child, about your great-grandfather, who had founded the D-s factory in the Urals? Sonny, you should not be here, go back to Earth, do not violate the Laws of the Creator…Sonny, you must return, return, return…” (Press-Extra newspaper, Issue 135, 1997)

The Martian Missions

Visiting the Martian surface has been challenging. Many of the early orbiters sent to the Red Planet seemed to simply disappear. The loss of Russia’s Fobos-2 Mars probe in 1989 was the most bizarre. Destined for Phobos, the Martian inner moon, Fobos-2 had several problems by the time it got there in January 1989. After making several observations of the planet, technical difficulties returned. A mysterious, miles-long oval object appeared in the pictures the doomed craft beamed back to Earth during the 2 months it probe circled Mars. No one could figure out what the object was. Then 2 days later the probe shut down. It’s led many to wonder if some force is trying to keep man off Mars.
