I’m an astronomer and I think aliens may be out there – but UFO sightings aren’t persuasive
Surveys indicate that nearly half of Americans believe in UFOs and alien visits, despite scientists claiming these views lack substantial evidence and can often be explained by mundane phenomena.

If intelligent aliens visit the Earth, it would be one of the most profound events in human history.
Surveys show that nearly half of Americans believe that aliens have visited the Earth, either in the ancient past or recently. That percentage has been increasing. Belief in alien visitation is greater than belief that Bigfoot is a real creature, but less than belief that places can be haunted by spirits.
Scientists dismiss these beliefs as not representing real physical phenomena. They don’t deny the existence of intelligent aliens. But they set a high bar for proof that we’ve been visited by creatures from another star system. As Carl Sagan said, “Extraordinary claims require extraordinary evidence.”
I’m a professor of astronomy who has written extensively on the search for life in the universe. I also teach a free online class on astrobiology. Full disclosure: I have not personally seen a UFO.
Unidentified flying objects
UFO means unidentified flying object. Nothing more, nothing less.
There’s a long history of UFO sightings. Air Force studies of UFOs have been going on since the 1940s. In the United States, “ground zero” for UFOs occurred in 1947 in Roswell, New Mexico. The fact that the Roswell incident was soon explained as the crash landing of a military high-altitude balloon didn’t stem a tide of new sightings. The majority of UFOs appear to people in the United States. It’s curious that Asia and Africa have so few sightings despite their large populations, and even more surprising that the sightings stop at the Canadian and Mexican borders.
Most UFOs have mundane explanations. Over half can be attributed to meteors, fireballs and the planet Venus. Such bright objects are familiar to astronomers but are often not recognized by members of the public. Reports of visits from UFOs inexplicably peaked about six years ago.
Many people who say they have seen UFOs are either dog walkers or smokers. Why? Because they’re outside the most. Sightings concentrate in evening hours, particularly on Fridays, when many people are relaxing with one or more drinks.
A few people, like former NASA employee James Oberg, have the fortitude to track down and find conventional explanations for decades of UFO sightings. Most astronomers find the hypothesis of alien visits implausible, so they concentrate their energy on the exciting scientific search for life beyond the Earth. https://www.youtube.com/embed/lAopNJMbFEI?wmode=transparent&start=0 Most UFO sightings have been in the United States.
Are we alone?
While UFOs continue to swirl in the popular culture, scientists are trying to answer the big question that is raised by UFOs: Are we alone?
Astronomers have discovered over 4,000 exoplanets, or planets orbiting other stars, a number that doubles every two years. Some of these exoplanets are considered habitable, since they are close to the Earth’s mass and at the right distance from their stars to have water on their surfaces. The nearest of these habitable planets are less than 20 light years away, in our cosmic “back yard.” Extrapolating from these results leads to a projection of 300 million habitable worlds in our galaxy. Each of these Earth-like planets is a potential biological experiment, and there have been billions of years since they formed for life to develop and for intelligence and technology to emerge.
Astronomers are very confident there is life beyond the Earth. As astronomer and ace exoplanet-hunter Geoff Marcy, puts it, “The universe is apparently bulging at the seams with the ingredients of biology.” There are many steps in the progression from Earths with suitable conditions for life to intelligent aliens hopping from star to star. Astronomers use the Drake Equation to estimate the number of technological alien civilizations in our galaxy. There are many uncertainties in the Drake Equation, but interpreting it in the light of recent exoplanet discoveries makes it very unlikely that we are the only, or the first, advanced civilization.
This confidence has fueled an active search for intelligent life, which has been unsuccessful so far. So researchers have recast the question “Are we alone?” to “Where are they?”
The absence of evidence for intelligent aliens is called the Fermi Paradox. Even if intelligent aliens do exist, there are a number of reasons why we might not have found them and they might not have found us. Scientists do not discount the idea of aliens. But they aren’t convinced by the evidence to date because it is unreliable, or because there are so many other more mundane explanations.
Modern myth and religion
UFOs are part of the landscape of conspiracy theories, including accounts of abduction by aliens and crop circles created by aliens. I remain skeptical that intelligent beings with vastly superior technology would travel trillion of miles just to press down our wheat.
It’s useful to consider UFOs as a cultural phenomenon. Diana Pasulka, a professor at the University of North Carolina, notes that myths and religions are both means for dealing with unimaginable experiences. To my mind, UFOs have become a kind of new American religion.

So no, I don’t think belief in UFOs is crazy, because some flying objects are unidentified, and the existence of intelligent aliens is scientifically plausible.
But a study of young adults did find that UFO belief is associated with schizotypal personality, a tendency toward social anxiety, paranoid ideas and transient psychosis. If you believe in UFOs, you might look at what other unconventional beliefs you have.
I’m not signing on to the UFO “religion,” so call me an agnostic. I recall the aphorism popularized by Carl Sagan, “It pays to keep an open mind, but not so open your brains fall out.”

MALMÖ, Sweden /PRNewswire/ — Guided by the vision of creating a better everyday life for the many people, Ingka Group, the largest IKEA retailer, is stepping up efforts to support customers with low price while ensuring long-term growth. In many IKEA markets around the world*, the price of restaurant meals will be halved Monday through Friday, and children will eat for free.
With hundreds of millions of guests visiting IKEA restaurants every year, the company aims to inspire a better everyday life through food that is healthier, more sustainable, and affordable. As part of ongoing investments in the in-store experience, Ingka Group is introducing this price drop to help people stretch their budgets, nourish their families, and find a little more joy.
For example, in France, the price of lunch for a family of four, which includes two hot-meals with meatballs for adults and two meals for kids, will cost EUR 6.96 instead of EUR 19.9. In addition, all restaurant guests will receive a EUR 5 voucher to use in-store.
“Food has always been very important for IKEA, and we wanted to enable even more people to enjoy our restaurant offer while exploring our home furnishing range,” says Tolga Öncü, Ingka Retail Manager (COO) at IKEA Retail (Ingka Group). “Securing the lowest possible price for our products is always our utmost goal, and this is even more important in today’s times of economic uncertainties and cost-of-living pressures.”
At the same time, IKEA is refreshing its food offer with new dishes inspired by Asian flavours, expanding affordable, healthy options for customers.
“We always look for ways to bring more variety to our food offer, especially with new plant-based options,” says Lorena Lourido Gomez, Global Food Manager, IKEA Retail (Ingka Group). “We will soon launch our very first falafel, adding this popular food to our restaurants and, later, to our Swedish Food Markets. Good quality, low price, and making a positive difference for the planet – those ingredients remain a guiding star for our food business.”
Heading toward the end of FY25, IKEA remains focused on helping customers make the most of their finances while delivering value through both food and home furnishing.

Slate Auto’s $20K EV Truck Dream Collapses Under Trump’s “Big Beautiful Bill”
Slate Auto’s sub-$20K electric pickup is no more—Trump’s new bill kills the EV tax credit that made the price possible.
Image Credit: Slate Auto
The Affordable EV Dream, Derailed
Slate Auto made waves in early 2025 by announcing an electric pickup truck with a revolutionary promise: a starting price under $20,000. With a minimalist, modular design and direct-to-consumer sales model, the company hoped to disrupt the industry by delivering a rugged, no-frills EV that everyday drivers could actually afford.
But that promise may now be broken.
In July 2025, the newly passed “Big Beautiful Bill” from President Donald Trump eliminated the $7,500 federal EV tax credit, a cornerstone of Slate’s pricing model. And as of now, Slate has quietly removed its sub-$20K price claims, signaling a dramatic shift in its market positioning.
What Was the Original Plan?
Slate Auto’s vision was simple:
Base price of the pickup: ~$25,000 Subtract $7,500 tax credit → final cost: $17,500 Optional bolt-on accessories and upgrades for customization
This formula positioned the Slate truck as a compelling solution for tradespeople, students, rural drivers, and eco-conscious buyers seeking low-cost alternatives to gas trucks.
What Changed?
The Trump administration’s “Big Beautiful Bill,” passed in July 2025, includes a provision that eliminates all federal EV tax credits starting September 30, 2025. That means:
No more $7,500 off at the point of sale Budget EVs like Slate’s are left to float—or sink—on their true retail pricing EV industry analysts warn of broader slowdowns in adoption
For Slate, it means their truck is no longer “America’s first under-$20K EV pickup.” Instead, the expected price now ranges from $25,000 to $27,500, and could rise to $35K with add-ons—putting it closer to competitors like the Ford Maverick Hybrid and Chevy Equinox EV.
The Fallout
This change hits hard for Slate, which built its brand on simplicity and accessibility. Without the tax credit:
Entry-level customers are priced out Preorder holders may cancel based on unexpected price hikes Market differentiation is weakened, as affordability was Slate’s primary value proposition
Meanwhile, critics argue the rollback of tax credits slows EV adoption at a critical time in the climate fight. Environmental groups and consumer advocates are already pushing back, saying the bill disproportionately hurts low- and middle-income Americans who were just beginning to consider electric vehicles.
What’s Next for Slate?
Slate says it still plans to begin production in late 2026, but without the EV credit, it must rework its pricing strategy and value offering. Possibilities include:
Offering fewer standard features Creating stripped-down fleet or worksite models Lobbying for state-level incentives to offset federal losses
Whether these changes will be enough to keep Slate competitive remains to be seen.
Final Thoughts
The electric vehicle space is undergoing seismic shifts, and the demise of the federal EV tax credit is likely to create ripple effects across the industry. For Slate Auto, the dream of a sub-$20K EV pickup may be over—but if they can pivot wisely, the company could still carve out a niche in the fast-evolving electric truck market.

A New Interstellar Visitor: Meet 3I/ATLAS, the Third Object from Beyond Our Solar System
Astronomers have discovered 3I/ATLAS, only the third known interstellar object to enter our solar system—here’s what we know so far.
A Cosmic Rarity: Another Visitor from the Stars
In an exciting development for astronomers and space enthusiasts alike, scientists have confirmed the discovery of a new interstellar object—officially named 3I/ATLAS—currently passing through our solar system. This marks only the third known object from another star system to visit us, following the mysterious ‘Oumuamua in 2017 and the icy 2I/Borisov in 2019.
The object was first detected on July 1, 2025, by the ATLAS telescope in Chile. Initially cataloged as A11pl3Z, further analysis confirmed that its speed and orbital trajectory are hyperbolic—meaning it’s not bound by the Sun’s gravity and is merely passing through, just like its rare predecessors.
What Do We Know About 3I/ATLAS?
Origin: The object’s interstellar origin is confirmed by its high velocity—traveling at around 60 km/s (37 miles per second)—and its hyperbolic orbit. Composition: Unlike ‘Oumuamua, which sparked debate due to its lack of a visible tail, 3I/ATLAS appears to be a comet, exhibiting a faint coma and short dust tail. Size: The comet’s nucleus could be as large as 10 kilometers (6 miles) across, though dust and debris around it may be inflating those estimates. Distance from Earth: It will come no closer than 150 to 240 million miles, posing no threat to our planet. Visibility: It’s currently about 420 million miles from the Sun and will reach its closest approach (perihelion) around October 29–30, 2025. After briefly disappearing behind the Sun, it may reappear for additional observation in December.
@stmblog 🚨 A comet from another star system is flying through our solar system right now! 🌠 Meet 3I/ATLAS — only the 3rd interstellar object ever seen! 👽✨ SpaceTok 3IATLAS Oumuamua Interstellar ScienceTok AstronomyFacts DidYouKnow CosmicVisitor #STMDailyNews https://stmdailynews.com/a-new-interstell…our-solar-system/ ♬ original sound – STMDailyNews – STMDailyNews
Why Interstellar Objects Matter
Interstellar objects are not just celestial curiosities—they are time capsules carrying information about the environments where they formed, likely in entirely different star systems. Their compositions, movements, and structures give scientists rare glimpses into the diversity of planetary building blocks in our galaxy.
‘Oumuamua puzzled scientists with its unusual shape and lack of comet-like activity, while 2I/Borisov looked more like a traditional comet. Now, 3I/ATLAS gives us another chance to compare and contrast these space travelers and deepen our understanding of how solar systems form and evolve.
Eyes on the Sky
Though faint and fast-moving, 3I/ATLAS is already being tracked by observatories around the world. With modern telescopes and tools that weren’t available even a decade ago, astronomers are optimistic about gathering unprecedented data on this rare visitor.
Whether you’re a seasoned stargazer or a casual cosmic tourist, it’s thrilling to know that something from another solar system is soaring through our cosmic backyard—reminding us of the vastness and wonder of the universe.
