New, extremely reactive chemical discovered in the atmosphere

Blue-whale-size asteroid to screech past Earth in close encounter on June 6 | Ancient Bronze Age city reemerges from Iraq river after extreme drought | New, extremely reactive chemical discovered in the atmosphere Created for {EMAIL} | [Web Version]( June 2, 2022 CONNECT WITH LIVESCIENCE  [Facebook]( [Twitter](  [LIVESCIENCE]( Amazing science every day [SIGN UP]( ⋅ [WEBSITE](  [] Top Science News [] [Blue-whale-size asteroid to screech past Earth in close encounter on June 6]( [Blue-whale-size asteroid to screech past Earth in close encounter on June 6]( (Erik Simonsen via Getty Images) An asteroid up to three times larger than a blue whale will zoom past Earth on Monday (June 6) at more than 16,000 mph (26,000 km/h), according to NASA. The asteroid, named 2021 GT2, is predicted to safely miss our planet by more than 2.2 million miles (3.5 million kilometers) — or roughly 10 times the average distance between Earth and the moon. Astronomers first detected the space rock last year and estimated its size at between 121 and 272 feet (37 to 83 meters) wide. While that sounds pretty big — between one and three times the length of a blue whale — it isn't large enough to be considered a potential hazard to Earth.

The Bronze Age city, at an archaeological site called Kemune, is a relic of the Mittani Empire (also spelled Mitanni Empire), an ancient kingdom that ruled parts of northern Mesopotamia from around 1500 B.C. to 1350 B.C. Researchers have long known of the remains of the city, but they can only investigate them during droughts.

The chemicals interact with other compounds extremely quickly, and their presence means that chemists will have to rethink just how processes in the atmosphere occur.

How is this possible?]( (September15 via Getty Images) In an extremely rare case, a Texas woman became pregnant while already pregnant and ultimately gave birth to twins who had been conceived roughly one week apart, according to news reports. This rare phenomenon, in which a second pregnancy occurs in the midst of another pregnancy, is known as "superfetation."

Recent analysis of a megalodon (Otodus megalodon) tooth with a rare abnormality — a groove all the way down the middle — hints that the dental deformity may trace its roots to an injury to the giant shark's jaw, perhaps caused by prey that fought back. In an illustration showing one possible encounter, a fish pierces the pursuing predator's jaw with its sharp bill, which may have set the stage for the megalodon growing a split tooth. Another possibility is that the big shark was impaled by a spine from a stingray, scientists wrote in a new study.
