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.”

Metrolink Offers Fare-Free Rides for Earth Day 2026 Across Southern California
Metrolink offers fare-free rides for Earth Day 2026 across Southern California, encouraging sustainable travel and reduced emissions.
Last Updated on April 21, 2026 by Daily News Staff
Metrolink Offers Fare-Free Rides for Earth Day 2026
LOS ANGELES — April 22, 2026 — In a continued push toward sustainable transportation, Metrolink will once again offer systemwide free rides on Earth Day, inviting commuters and travelers to leave their cars behind and explore a cleaner way to move across the region.
A One-Day Opportunity to Ride Free
On Wednesday, April 22, passengers can board any Metrolink train — including the Arrow service — without purchasing a ticket. The initiative is part of the broader celebration of Earth Day, encouraging environmentally conscious travel choices.
The fare-free program is designed to appeal to both regular riders and first-time users, particularly those navigating Southern California’s persistent traffic congestion and rising fuel costs.
Encouraging Sustainable Travel Habits
“Earth Day is a reminder that small changes, like choosing public transit over driving one day a week, can have a meaningful impact on our environment,” said Doug Chaffee, chair of the Metrolink Board.
With gas prices continuing to strain household budgets, the agency hopes the initiative will inspire more residents to consider rail as part of their regular commute.
Regional Connections Expand Access
Metrolink’s Earth Day promotion aligns with similar efforts by other Southern California transit providers. Riders can seamlessly connect to services operated by: LA Metro and the Orange County Transportation Authority, Riverside County Transportation Commission, San Bernardino County Transportation Authority and Ventura County Transportation Commission.
These partnerships extend the reach of fare-free travel across a six-county region, making it easier for riders to explore destinations without relying on personal vehicles.
Service Adjustments and Rider Tips
Passengers should note that trains will operate on a reduced weekday schedule, implemented earlier this spring. Despite the adjustment, all Metrolink lines and station cities remain in service.
For those planning a trip:
- No ticket is required — simply board the train
- Bikes are welcome, with capacity ranging from three bikes per standard car to nine in designated bike cars
- A curated destination guide highlights attractions within walking or biking distance of stations
Environmental and Economic Impact
Metrolink is also promoting its Personal Impact Calculator, a digital tool that allows riders to estimate how switching from driving to rail can reduce greenhouse gas emissions and lower fuel expenses.
A Broader Trend in Public Transit
Fare-free transit days have gained traction nationwide as agencies look to boost ridership and promote sustainability. Southern California’s expansive commuter rail network makes it particularly well-suited for such initiatives, offering a viable alternative to one of the country’s most car-dependent regions.
Bottom Line
Metrolink’s Earth Day promotion is more than a one-day free ride — it’s a strategic effort to shift commuter behavior, reduce environmental impact, and showcase the convenience of regional rail. For Southern Californians, April 22 presents a low-risk opportunity to rethink how they travel.

Money Management: The Importance of Financial Literacy
You may have mastered the core subjects like math and grammar in school, but financial literacy – or understanding the basics of money management in order to help you make better financial decisions – often goes overlooked before adulthood. It’s not so much a course of study as it is a plan of action. When you understand how to earn, save, spend and invest wisely, you aren’t just building a stable future for yourself, but your family and community as well.
(Feature Impact) You may have mastered the core subjects like math and grammar in school, but financial literacy – or understanding the basics of money management in order to help you make better financial decisions – often goes overlooked before adulthood. It’s not so much a course of study as it is a plan of action.
Financial literacy in the United States has remained stagnant at generally low levels for several years, according to research from TIAA Institute and the Global Financial Literacy Excellence Center, with even lower levels among Gen Z. Yet greater financial literacy – including key aspects such as goal-setting, budgeting, saving, credit management and investing – is strongly linked to better financial outcomes, including lower rates of debt constraint and financial fragility.
While emboldening yourself to understand financial terms can be a little overwhelming at first, once you have a grasp of basic concepts you can begin to get a handle on your money and make better financial decisions. Simply put: When you understand how to earn, save, spend and invest wisely, you aren’t just building a stable future for yourself, but your family and community as well.
From nonprofit partnerships to volunteer-led programs and fee online resources, Schwab and its employees help millions of people every year build the knowledge and confidence to take charge of their financial futures by serving as board members, mentors, role models and educators.
Because financial health is a lifelong journey, the earlier people learn vital money skills, the better. That’s why the financial advisory services provider develops education programs geared toward kids that continue into adulthood, helping people no matter where they are on their journeys.
Talk Money
It’s never too early to start a conversation about financial literacy. Having teens identify goals that are important to them – such as concert tickets or a first car – can kickstart coversations about money. Working with your child (and a financial advisor, if necessary) on a plan for saving to realize those goals can serve as a jumping off point. After achieving some success, their enthusiasm may grow, which is a powerful motivator to keep saving.
Support School Initiatives and Programs
Outreach programs that empower young people to make smart financial decisions is key to a bright future. Programs like Money Matters – Schwab’s flagship financial education program utilized by the Boys & Girls Clubs of America – gives young people hands-on experience with all aspects of money and investing.
This example, and others, don’t just include program funding – they build partnerships that create impact and opportunity with national collaborations that reach more than 17 million youth annually, empowering young people with the tools and confidence to make smart financial decisions for life.
Spread the Financial Love
Championing financial literacy empowers everyone – individuals, families and communities. By serving as a board member, mentor, role model or educator to help bring financial literacy to others in your community, you can supply the tools and knowledge to lead programs that focus on giving back, empowering future generations in countless ways.
