As Earthlings, we're curious about whether alien civilizations like ours are out there or if they exist at all—which is why scientists were intrigued when a mysterious shard of metal exhibited signs that it might have come from intelligent minds on a distant planet.
This peculiar specimen fell to Earth around 1947 in a supposed UFO wreck that seemed linked to the infamous Roswell incident, which had members of the general public believing a flying saucer had crashed to Earth. It turned out that the debris found in Roswell was actually from a U.S. Air Force balloon meant to spy on Soviet nuclear experiments.
The true origins of the metallic specimen were debated for decades. Eventually, Blink-182 frontman and UFO enthusiast Tom DeLonge's To the Stars Academy got a hold of it. The organization independently researches possible alien phenomena, and the sample had an apparently unprecedented material structure that could indicate an extraterrestrial technosignature . Then, the All-Domain Anomaly Resolution Office (AARO), which investigates unidentified anomalous phenomena (UAP) for the U.S. government, took over the investigation to learn more about the object's physical and chemical properties that made it potentially capable of inertial mass reduction—levitation.
The object in question is a magnesium alloy whose main components are magnesium and zinc. It also contains bismuth, lead, and other trace elements.
In looking for alien biosignatures, ORNL scientists wanted to see whether the isotopes of the metals in this alloy were from Earth. Finding out where the metals originated meant investigating their isotopic signatures. These represent the ratios of different element isotopes in a material (when versions of the same element exist, but each has a different atomic mass.) Analysis showed that the isotopic signatures of magnesium and lead indicated a terrestrial origin. The magnesium's isotopic signature had undergone some fractionation, or separation of lighter and heavier isotopes, probably due to stress from heat and physical or chemical manufacturing processes. However, it was still within the normal range for magnesium that forms on Earth, not an alien biosignature.
