When I was in grade school we did “duck ‘n cover” drills. Ducking under a desk and covering your head was suppose to protect us from an atomic bomb drop. It was the height of the cold war between the United States and Russia.
I lived in Phoenix Arizona which was a small (by today’s standards) city surrounded by miles and miles of uninhabitable dessert where many alien spacecraft had been observed.
I prayed that the aliens would land and the entire world would then, out of necessity, come together in solidarity to protect the planet.
“Weird space object ‘Oumuamua’ was not an alien spacecraft after all, scientists say. The 1/4-mile long rock was first spotted in October 2017 by astronomers peering through a telescope atop Mount Haleakala in Maui, Hawaii. In the weeks after that, other ground-based telescopes around the world and space-based telescopes in orbit continued to monitor Oumuamua (Hawaiian for “scout” or “messenger”) as it zipped through the solar system at about 85,700 mph.”
There was also wild speculation that it came from an alien civilization.
“After a fairly exhaustive search, scientists couldn’t find any artificial radio signals coming from the interstellar objet known as Oumuamua.”
“The alien spacecraft hypothesis is a fun idea, but our analysis suggests there is a whole host of natural phenomena that could explain it,” said Matthew Knight, the study lead author from the University of Maryland, in a news release.
‘”While Oumuamua’s interstellar origin makes it unique, many of its other properties are perfectly consistent with objects in our own solar system,” said study co-author Robert Jedicke of the University of Hawaii. In fact, Oumuamua’s orbit, its path through our solar system, matches a prediction published in a scientific journal by Jedicke and his colleagues six months before Oumuamua’s discovery.”
One theory is that the object could have been ejected by a gas giant planet orbiting another star.
“Even though we know it’s a natural phenomenon, “we have never seen anything like Oumuamua in our solar system,” Knight said. “It’s really a mystery still,” he said.”
Decades later “duck ‘n cover” has been replaced by “lock down drills” for shooters. The aliens are still waiting for us to figure out how to come together without their help.
The new study was published in the peer-reviewed British journal Nature Astronomy.
