Date discovered: 1973
Location discovered: Romania
This object is very similar in appearance to the old Bob White alien artifact found back in 1985, when it fell from a huge ball of light in the sky.
Bob White states;
"It was huge, the size of a very big barn. I got out of the car for a better look.
"For some unknown reason, Jan turned on the headlights, and this light went up in the sky as fast as my eyes could follow it.
"Then I saw another small light, bright orange with a tinge of yellow, white, and blue falling from it."

Mr White said he climbed an incline and headed for where he thought it would have landed.
He said: "I found a groove in the ground about 18 inches deep and nine inches wide.
"I followed the groove and there it lay.
"It was still glowing."
After 13 laboratory tests it was confirmed the discovery was a solid centred aluminum alloy, just like this new UFO fragment found in Romania. Also the color appears the same.

A piece aluminium that looks as if it was handmade is being hailed as 250,000-year-old proof that aliens once visited Earth.
The discovery of the mysterious chunk of metal in communist Romania in 1973 was not made public at the time, according to CEN.
Testing has since revealed that the object is made of 12 metals and is 90 per cent aluminium with Romanian officials dating it as being 250,000 years old.
The initial results were later confirmed by a lab in Lausanne, Switzerland, CEN reports.
Metallic aluminium was not really produced by mankind until around 200 years ago, so the discovery of the large chunk that it claimed to be up to 250,000 years old is being held up as a sensational find.
In 1973, builders working on the shores of the Mures River not far from the central Romanian town of Aiud found three objects 10 metres (33 feet) under the ground.
They appeared to be unusual and very old, and archaeologists were bought in who immediately identified two of them as being fossils.
The third looked like a piece of man-made metal, although very light, and it was suspected that it might be the end of an axe.
All three were sent together with the others for further analysis to Cluj, the main city of the Romanian region of Transylvania.
It was quickly determined that the two large bones belonged to a large extinct mammal that died 10,000-80,000 years ago, but experts were stunned to find out that the third object was a piece of very lightweight metal, and appeared to have been manufactured.
The object is 20 centimetres (7.8 inches) long, 12.5 centimetres (4.9 inches) wide and 7 centimetres (2.8 inches) thick.
What puzzled experts is that the piece of metal has concavities that make it look as if it was manufactured as part of a more complex mechanical system.
Now a heated debate is going on that the object is actually part of a UFO and proof of visitation by an alien civilisation in the past.
Gheorghe Cohal, the Deputy Director of the Romanian Ufologists Association, told local media: 'Lab tests concluded it is an old UFO fragment given that the substances it comprises cannot be combined with technology available on Earth.'
However, local historian Mihai Wittenberger claims that the object is actually a metal piece from a World War II German aircraft.
He believes that it is a piece of the landing gear from a Messerschnmitt ME 262.
The UFO hunters say that this explanation does not explain the age of the artifact.
The metal object has now gone on display in the History Museum of Cluj-Napoca, with a sign that reads 'origin still unknown'.
