About 66 million years back, a 10-kilometer-wide asteroid had crashed onto the Earth, which resulted in the annihilation of the dinosaurs. It is something to the atomic bomb dropped the US on the city of Hiroshima that is located in Japan on 6 August 1945 and this ensuing blast had resulted in the death of around 100,000 people. The asteroid strike is believed to have turned the rocks into molten glass. This glass while swirling through the air as ejecta had solidified and developed into spherules or beads and later poured down on the impact site. The atomic bomb thrown on the city had also shown to have formed molten glass in certain parts of the city. The discovered beads have been termed by the researchers as Hiroshimaites.
According to Geologist Mario Wannier, the 17 samples collected from the beach sand present around Motoujina Peninsula and Miyajima Island in Hiroshima have shown the shells of the organism to actually have spherules. This discovery of the spherules on the beach was found to be exactly similar to that of the dinosaur-killing asteroid. The beads remained untouched on the beach. The formation of glass from materials needs the temperature to reach up to 1,800°C. The bomb named Little Boy had forced the rocks and sand on the Hiroshima Bay to reach the hellish temperatures.
The Cretaceous-aged granites have crystals of quartz and feldspar that form a major part of the sand grains on the beach. However, there are other materials as well that turned into beads. The Hiroshima is found in pieces in the spherules. The beads have shown the presence of iron and steel as well. The beads lack radioactivity of any kind whereas those from the Alamogordo, N.M., which was a test site, showed to be radioactive. This, however, does not prove Hiroshimaites absence of formation during the atomic blast. NASA spotted an asteroid mov epast the Earth at nearly 26,000mph. The current asteroid KT is a type of Apollo space rock present on one of the orbital trajectory.
