On June 25, 2021, the Workplace of the Director of Nationwide Intelligence launched a much-anticipated report on UFOs to Congress. The navy has rebranded unidentified flying objects as unidentified aerial phenomena – UAPs – partially to keep away from the stigma that has been connected to claims of aliens visiting the Earth for the reason that Roswell incident in 1947. The report presents no convincing proof that alien spacecraft have been noticed, however a few of the knowledge defy straightforward interpretation.
I’m a professor of astronomy who has written extensively on the seek for life within the universe. I additionally train a free on-line class on astrobiology. I don’t consider that the brand new authorities report or every other sightings of UFOs prior to now are proof of aliens visiting Earth. However the report is essential as a result of it opens the door for a severe have a look at UFOs. Particularly, it encourages the U.S. authorities to gather higher knowledge on UFOs, and I feel the discharge of the report will increase the possibilities that scientists will attempt to interpret that knowledge. Traditionally, UFOs have felt off limits to mainstream science, however maybe no extra.
What’s within the UFO Report?
The No. 1 factor the report focuses on is the shortage of high-quality knowledge. Listed below are the highlights from the slender nine-page report, overlaying a complete of 144 UAP sightings from U.S. authorities sources between 2004 and 2021:
“Restricted knowledge and inconsistent reporting are key challenges to evaluating UAP.”
Some observations “might be the results of sensor errors, spoofing, or observer misperception.”
“UAP clearly pose a security of flight concern and will pose a problem to U.S. nationwide safety.”
Of the 144 sightings, the duty power was “in a position to determine one reported UAP with excessive confidence. In that case, we recognized the thing as a big, deflating balloon. The others stay unexplained.”
“Some UAP many be applied sciences deployed by China, Russia, one other nation, or non-governmental entity.”

UFOs Are Taboo Amongst Scientists
UFO means alien craft. Nothing extra, nothing much less. You’d suppose scientists would benefit from the problem of fixing this puzzle. As a substitute, UFOs have been taboo for educational scientists to research, and so unexplained reviews haven’t acquired the scrutiny they deserve.
One purpose is that almost all scientists suppose there’s much less to most reviews than meets the attention, and the few who’ve dug deeply have largely debunked the phenomenon. Over half of sightings will be attributed to meteors, fireballs and the planet Venus.
One more reason for the scientific hesitance is that UFOs have been co-opted by widespread tradition. They’re a part of a panorama of conspiracy theories that features accounts of abduction by aliens and crop circles. Scientists fear about their skilled reputations, and the affiliation of UFOs with these supernatural tales causes most researchers to keep away from the subject.
However some scientists have regarded. In 1968, Edward U. Condon on the College of Colorado revealed the first main educational examine of UFO sightings. The Condon Report put a damper on additional analysis when it discovered that “nothing has come from the examine of UFOs prior to now 21 years that has added to scientific information.”
Nonetheless, a overview in 1998 by a panel led by Peter Sturrock, a professor of utilized physics at Stanford College, concluded that some sightings are accompanied by bodily proof that deserves scientific examine. Sturrock additionally surveyed skilled astronomers and located that just about half thought UFOs had been worthy of scientific examine, with increased curiosity amongst youthful and extra well-informed astronomers.
If astronomers are intrigued by UFOs – and consider some instances deserve examine with educational rigor – what’s holding them again? A historical past of distrust between ufologists and scientists hasn’t helped. And whereas UFO analysis has employed a few of the instruments of the scientific methodology, it has not had the core of skeptical, evidence-based reasoning that demarcates science from pseudoscience.
A search of 90,000 current and present grants awarded by the Nationwide Science Basis finds none addressing UFOs or associated phenomena. I’ve served on overview panels for 35 years, and may think about the response if such a proposal got here up for peer overview: raised eyebrows and a fast vote to not fund.

A Decadeslong Seek for Aliens
Whereas the scientific group has virtually completely prevented participating with UFOs, a way more mainstream seek for clever aliens and their know-how has been occurring for many years.
The search is motivated by the truth that astronomers have, thus far, found over 4,400 planets orbiting different stars. Referred to as exoplanets, some are near the Earth’s mass and at simply the proper distance from their stars to doubtlessly have water on their surfaces – that means they could be liveable.
Astronomers estimate that there are 300 million liveable worlds within the Milky Approach galaxy alone, and each is a potential alternative for all times to develop and for intelligence and know-how to emerge. Certainly, most astronomers suppose it most unlikely that people are the one or the primary superior civilization.
This confidence has fueled an energetic seek for extraterrestrial intelligence, often known as SETI. It has been unsuccessful up to now. In consequence, researchers have recast the query “Are we alone?” to “The place are the aliens?” The absence of proof for clever aliens is known as the Fermi paradox. First articulated by the physicist Enrico Fermi, it’s a paradox as a result of superior civilizations needs to be unfold all through the galaxy, but we see no signal of their existence.
The SETI exercise has not been immune from scientists’ criticism. It was starved of federal funding for many years and lately has gotten most of its assist from non-public sources. Nonetheless, in 2020, NASA resumed funding for SETI, and the brand new NASA administrator desires researchers to pursue the subject of UFOs.
On this context, the intelligence report is welcome. The report attracts few concrete conclusions about UFOs and avoids any reference to aliens or extraterrestrial spacecraft. Nonetheless, it notes the significance of destigmatizing UFOs in order that extra pilots report what they see. It additionally units a aim of shifting from anecdotal observations to standardized and scientific knowledge assortment. Time will inform if that is sufficient to attract scientists into the hassle, however the transparency to publish the report in any respect reverses a protracted historical past of secrecy surrounding U.S. authorities reviews on UFOs.
I don’t see any convincing proof of alien spacecraft, however as a curious scientist, I hope the subset of UFO sightings which can be really unexplained will get nearer examine. Scientists are unlikely to weigh in if their skepticism generates assaults from “true believers” or they get ostracized by their colleagues. In the meantime, the reality remains to be on the market.
