NASA held its first public meeting on UFOs on Wednesday a study into unexplained sightings and insisted it91裸聊视频檚 not hiding anything.

The space agency televised the four-hour hearing featuring an independent panel of experts who vowed to be transparent. The team includes 16 scientists and other experts selected by NASA including , the first American to spend nearly a year in space.

91裸聊视频淚 want to emphasize this loud and proud: There is absolutely no convincing evidence for extraterrestrial life associated with91裸聊视频� unidentified objects, NASA91裸聊视频檚 Dan Evans said after the meeting.

Still, hundreds of questions from the public that poured in ahead of time were skeptical and veered into conspiracy theories.

NASA launched the study to probe what it calls UAPs 91裸聊视频� short for unexplained anomalous phenomena 91裸聊视频� in the sky, in space or under the sea.

Optical illusions can explain some of this, said Kelly, a former Navy fighter pilot. He recalled a Tomcat flight off Virginia Beach years ago during which his radar intercept officer in the back seat was convinced they91裸聊视频檇 flown past a UFO.

91裸聊视频淚t turns out it was Bart Simpson, a balloon,91裸聊视频� Kelly said. 91裸聊视频淎nd in my experience, the sensors kind of have the same issues as the people91裸聊视频檚 eyeballs.91裸聊视频�

Evans pointed out that the livestream of the meeting led to considerable trolling. That comes on top of 91裸聊视频渙nline abuse91裸聊视频� directed toward several committee members.

Harassment detracts from the scientific process and reinforces the stigma surrounding the topic, said Evans, adding that NASA security is dealing with it.

91裸聊视频淚t91裸聊视频檚 precisely this rigorous, evidence-based approach that allows one to separate the fact from fiction,91裸聊视频� he said.

The group is looking at what unclassified information is available on the subject and how much more is needed to understand what91裸聊视频檚 going on in the sky, according to astrophysicist David Spergel, the committee91裸聊视频檚 chair who runs the Simons Foundation.

No secret military data are included, such as anything surrounding the suspected spy balloons from China spotted flying over the U.S. earlier this year.

The meeting was held at at NASA headquarters in Washington with the public taking part remotely.

A final report is expected by the end of July.
