Neil deGrasse Tyson—astrophysicist, director of the Hayden Planetarium, and host of the StarTalk podcast—is one of America’s most popular science communicators. He has worked tirelessly for more than four decades to improve scientific literacy and instill a greater sense of awe about the cosmos.

In his new book, Take Me to Your Leader, Tyson loosens his space tie a bit and has fun examining the possibility of aliens visiting Earth from scientific, historical, and pop-culture perspectives.

Upworthy spoke with Tyson about why he chose this moment to discuss aliens, how we should greet them if—or when!—they land, and how he hopes to broaden people’s perspectives through the alien narrative.

Why now is the perfect time to talk about aliens

The September 9, 2025, congressional hearing, “Restoring Public Trust Through UAP Transparency and Whistleblower Protection,” was a watershed moment for UFO/UAP disclosure, shifting the conversation from science fiction and conspiracy theories to a national security issue. 

“The real transition for me was the high-ranking officials who came forth in Congress,” Tyson said. “Much of which landed in that two-hour, hour-and-fifty-minute documentary, Day of Disclosure. So it elevated once it hit that level. It was no longer the sleepy farmer in the back 40 reporting on a glowing object over his farm. It was no longer the drunken revelers coming out of the bar at 2 a.m. reporting on the glowing thing in the sky. Upon reaching that, I said, ‘All right, I can’t sit back any further. I have to write this book.’”

The turning point in the public discussion about aliens inspired Tyson to examine extraterrestrials from a practical, science-based perspective.

“It’s an attempt to anchor the conversation, to celebrate the imaginations that have created aliens in our pop culture, and to pose a set of questions for those who may have had a one-on-one encounter with aliens,” he said.

Who should represent humanity if aliens arrived on Earth?

What if aliens were to visit Earth, as his book’s title suggests, and demand, “Take me to your leader”? The Earth doesn’t have a singular leader to turn to, so who would Tyson anoint to make first contact with the alien delegation? His choice: former president Barack Obama.

Tyson says that Obama would be a great representative of Earth after a recent conversation the 44th president had with Stephen Colbert, in which he said he “would be a good emissary for the planet. I feel I have a diverse background, some experience in statecraft and diplomacy. I’m friendly. I actually think I can do a pretty good job.”

“He thinks he would be a good emissary for Earth, and that would be true,” Tyson shared. “First, he’s a nice guy, plus he’s smart, and he’s also scientifically literate. I think he sees his value there because a politician who’s also a diplomat would value that role if you’re meeting someone from another land, another place, another time.”

However, Tyson wouldn’t send Obama alone to greet the aliens. He said Obama would need a team of experts to greet the delegation, including a cryptographer, an astrophysicist, an engineer, and a mathematician, “because math is the language of the universe.”

Who would be the astrophysicist? Tyson, of course. “I’d be the astrophysicist just for good measure,” he joked. That’s no surprise, considering one of the first lines in his book is: “Ever since childhood I’ve wanted to be abducted by aliens.”

Tyson adds that it would be dangerous for humanity if we sent conspiracy theorists to meet our new friends.

“There are people who don’t think we went to the moon, people who think Earth is flat. And I say without hesitation to leave them behind on your first encounter with the alien,” he warned. “You’ve got to leave the best impression on them as you possibly can. So, you want humans to have a fighting chance to be respected by our new friends.”

Tyson challenges Hollywood’s conceptions of alien life

In Take Me to Your Leader, Tyson deconstructs the notion that if aliens were to visit Earth, they would be humanoid creatures, such as the bar patrons on Mos Eisley in Star Wars or the big-eyed “gray” aliens popularized by Whitley Strieber’s Communion series.

“I’d like to think of it as a force for Hollywood to up its game. That’s what [author] Andy Weir did with Project Hail Mary. His alien was crab-oid, not humanoid, and it was made of a material that resembled rocks, and they were really good engineers,” Tyson said. “So, Andy Weir tried to break that mold. And I would be happier if I saw more of that.”

The alien question holds up a mirror to humanity

Ultimately, Take Me to Your Leader is a lighthearted look at how aliens appear in American culture through movies and TV, conspiracy theories, sci-fi speculation, quasi-encounters, and our collective imaginations. Some may be disappointed that it doesn’t provide hard evidence of alien existence. But its real accomplishment is helping humans better understand themselves through imagining otherworldly beings.

“It is the summation of my life’s thinking and observing. Humans, what we believe, what we count as evidence, what convinces us. The universe is quite susceptible to people’s personal theories about things,” Tyson said. “A lot of the cultural references, it’s not because I am some deep anthropologist, although in a small way, we all are. My father was a sociologist, so I have some baptism in thinking about people and what makes us tick. So the referencing to aliens and our relationship with them and their relationship with us was pumped by these very factors.”

While a bottle of bubbles might seem out of place in a hospital setting, you might be surprised to learn that, for thousands of children around the world born with cleft lip and palate, they can be a helpful tool in comprehensive cleft care. Lilia, who was born with cleft lip and palate in 2020, is one of the many patients who received this care. 

As a toddler, Lilia underwent two surgeries to treat cleft lip and palate with Operation Smile’s surgical program in Puebla, Mexico. Because of Operation Smile’s comprehensive care, it wasn’t long before her personality transformed: Lilia went from a quiet and withdrawn toddler to an exuberant, curious explorer, babbling, expressing herself with a variety of sounds, and engaging with others like any child her age. 

Lilia is now a healthy five-year-old, with the same cheerful attitude and boundless energy. Her progress is the result of care at every level, from surgery to speech therapy to ongoing support at home—but it’s also evidence that small, sustained interventions throughout it all can make a meaningful difference. 

Cleft Conditions: A Global Problem

Since 1982, Operation Smile has provided cleft lip and cleft palate surgeries to more than 500,000 patients worldwide with the help of generous volunteers and donors. Cleft conditions are congenital conditions, meaning they are present at birth. With cleft lip and palate, the lip or the roof of the mouth do not form fully during fetal development. Cleft conditions put children at risk for malnutrition and poor weight gain, since their facial structure can make feeding challenging. But cleft conditions can have an enormous social impact as well: Common difficulties with speech can leave kids socially isolated and unable to meet the same developmental milestones as their peers. 

Surgery is a vital step in treating cleft conditions, but it’s also just one part of a much larger solution. Organizations like Operation Smile emphasize the importance of multi-disciplinary teams that provide comprehensive, long-term care to patients across many years. This approach, which includes oral care, speech therapy, nutritional support, and psychosocial care, not only aids in physical recovery from surgery but also helps children develop the skills and confidence to eat easily, speak clearly, and engage in everyday life. This ensures that each patient receives the full range of support they need to thrive. 

A Playful (and Powerful) Solution

Throughout a patient’s care, simple tools like bubbles can play a meaningful role from start to finish. 

Immediately before surgery, children are often in a new and unfamiliar environment far from home, some of them experiencing a hospital setting for the first time. When care providers or loved ones blow bubbles, it’s a simple yet effective technique: Not only are the children soothed and distracted, the bubbles also help create a sense of joy and playfulness that eases their anxiety. 

In speech therapy, bubbles can take on an even more important role. Blowing bubbles requires controlled airflow, as well as the ability to form a rounded “O” shape with the lips, which are skills that children with cleft conditions may struggle to develop. Practicing these skills with bubbles allows children to gently strengthen their facial muscles, improve breath control, and support the motor skills needed for speech development. Beyond that, blowing bubbles can help kids connect with their parents or providers in a way that’s playful, comforting, and accessible even for very young patients. 

Finally, bubbles often follow patients with cleft conditions home in the “smile bags” that each patient receives when the surgical procedure is finished. Smile bags, which help continue speech therapy outside of the hospital setting, can contain language enrichment booklets, a mirror, oxygen tubing, and bubbles. While regular practice with motor skills can help with physical recovery, small acts of play help as well, giving kids space to simply enjoy themselves and join in on what peers are able to do.

Bubbles at Home and Beyond

Today, because of Operation Smile’s dedication to comprehensive cleft care, Lilia is now able to make friends and speak clearly, all things that could have been difficult or impossible before. Instead of a childhood defined by limitation, Lilia—and others around the world—can look forward to a childhood filled with joy, learning, discovery, friends, and new possibilities.

Levi Kelly wanted to go small. Very small. As someone who loves building and touring tiny homes, along with unique Airbnbs and cabins, he wanted to create something truly special. Though the idea of a tiny home isn’t new and certainly began picking up steam in the early 2000s, Kelly wanted to raise— or, in this case, lower—the bar and make a statement about just how efficient he could get.

In an Instagram clip originally posted just over a year ago, but now making the rounds on social media again, Kelly shows viewers this extraordinary tiny home. Reminiscent of a tree house, its dark brown exterior and cheery windows look genuinely inviting. The most shocking part? It’s only 19.46 square feet.
