If the first war object ever found in our solar system is actually an empty spacecraft, it acts strictly.
A search for radio signals comes from Oumuamua, the mysterious remote visitor that has swell in the past solar system, becoming empty, new study reports.
"We were looking for a sign that would prove that this object incorporates some technology – it is of artificial origin," said lead author Gerry Harp of the SETI Foundation ( Search for Intelligent Intelligence) in Mountain View, California, statement.

"We did not get any such emissions, despite a pretty sensitive search," added Harp. "Although our observations are not a natural source that is not natural for" Oumuamua ", they contain important data in obtaining its likely circle."
He used a harp and colleagues to the Allen Telescope Array (ATA) colleagues of the SETI Foundation, a system of 42 radio food in North California, to listen to the possible Oumuamua signs from November 23 to December 5 last year. At the time, the cigarette shape object was about 170 million miles (275 million kilometers) of Earth – almost twice the distance from planet to the sun.
The team listened to transport with a frequency of between 1 and 10 gigahertz, with a decision of 100 kilohertz. The observation campaign was able to lift signals produced by an omnidirectional transmitter with a power of between 30 and 300 milliwatts, the researchers said.
"In all cases, these restrictions to the powers that could be detected are quite moderate – similar to cell phones or citizen band radios," the representatives of the SETI Foundation wrote in the same statement.
The harp and the team of the only group to collect on Oumuamua were not the last fall. The Breakthrough Project also sought $ 100 million, using the Robert C. Byrd Green Bank Telescope in West Virginia. That search did not turn anything too.
Scientists of SETI have such an interest in Oumuamua because of the origin and wonder of the object. And Oumuamua is an incredible, needle-shaped body, which is roughly six times longer than it's. And, during his voyage through the Earth's neighborhood late last year, it showed an incredible acceleration – a movement that can not be attributed to the removal of the sun, planets or other objects.
The leading explanation says that Oumuamua is a different comet, and the uneven movement was the result of a migration. (When comets are close to the sun and heating, jets often fall off their frozen layers; such jet can act as small stimulants, by pushing bodies like this and that.)
But some scientists have praised that Oumuamua could be a spacecraft ship of some kind, perhaps a quiet auditor who has a task to check our neck of cosmic forests. Harvard astronomers Shmuel Bialy and Avi Loeb recently introduced such an incident, indicating that "Oumuamua could be" sailing "and pushed along the star.
Unfortunately, such a speculation about "Oumuamua" may possibly reign forever. The object was fleeing beyond our most powerful telescopes for a long time, so it's probably never going to look at it again.
The new study will be published in the February 2019 edition of the Acta Astronautica magazine.
