The US Department of Defense published a report on unidentified flying objects last year, but there are still many unanswered questions. So far there is no explanation for at least 140 celestial phenomena. A new NASA study aims to shed light on the matter.

The US space agency NASA (National Aeronautics and Space Administration) has commissioned a new study on unidentified flying objects. The study, led by astrophysicist David Spergel, should identify existing data from autumn, find out how best to collect data in the future and how NASA can use this data to better understand unidentified flying objects scientifically in the future, the authority said on Thursday. “Given the lack of observations, our first task is simply to collect the most robust data set we can collect,” Spergel said.

The researchers wanted to identify what data exists – from civilians, the government, non-governmental organizations (NGOs) and companies. The study is expected to last around nine months and all results will be made public. NASA said there was no evidence that unidentified flying objects were of extraterrestrial origin.

The investigation was agreed with the US government, but not part of their own investigation. Last year, the US Department of Defense published an eagerly awaited report by the “Unidentified Aerial Phenomena Task Force” on the subject, according to which there are at least no explanations for around 140 celestial phenomena from the past two decades.

At the same time, it was determined that these phenomena posed a security risk to air travel and could also potentially pose a national security risk to the United States. Therefore, a plan should now be drawn up as to how they could be better examined and understood. In May there was the first hearing in the US House of Representatives on the subject in more than 50 years.
