The U.S. government has a brand new office that has been open for half a year.

The director of the All-Domain Anomaly Resolution Office told the Associated Press that the office has received hundreds of new reports from the military. More than 140 unexplained flying objects have been reported by the military, which was previously described in a report from the Pentagon.

The government's preferred name for unexplained phenomena, or UAP, is seen in the air, under water and in space.

The Pentagon established an office to investigate unexplained phenomena in space.

There was no hint of alien activity in any of the reports.

The mission of the AARO is to consolidate and investigate reports of unexplained flying objects. The Department of Defense defines a UAP as "anything in the air, on land, in the sea or under the sea that can't be identified, and which might pose a threat to U.S. military installations or operations."

The sudden influx of new reports may be due to recent outreach efforts by the AARO.

Pentagon officials told the New York Times in November that a number of reported incidents have already been solved. The officials said that "relatively ordinary" drones from nations such as China and Russia are likely to be the reason for many unexplained flying objects.

AARO is working on procedures to get rid of common sources of UAP, such as foreign or domestic aircraft that may leave distinct techno-signatures, or signs they were made using technology. The office is about to release a report with more information.
