Harvard professor believes he's found fragments of alien technology

Harvard professor Avi Loeb believes he may have found fragments of alien technology from a meteor that landed in the waters off of Papua New Guinea in 2014.

Loeb and his team just brought the materials back to Harvard for analysis. The U.S. Space Command can confirm with almost near certainty, 99.999%, that it came from another solar system. The government gave Loeb a 10 km (6.2 mile) radius of where it may have landed.

"We found ten spherules. These are almost perfect spheres, or metallic marbles. When you look at them through a microscope, they look very distinct from the background," explained Loeb, "They have colors of gold, blue, brown and some of them resemble a miniature of the Earth."

Their composition analysis showed that the spherules are made of 84% iron, 8% silicon, 4% magnesium and 2% titanium, plus trace elements. They are sub-millimeter in size. The crew found 50 of them in total.

There is no indication that the pieces are fragments of a larger piece, but the materials are elements that would likely survive an entry into the Earth's atmosphere.
