ALF

In case you didn’t know, this beloved TV character’s name is not short for "Alfred." It actually comes from the term " A lien L ife F orm," but don’t be alarmed: This alien is as friendly as they come. ALF is the quirky and lovable adopted family member of the Tanner family, who gained the heart of the American public in the 80s and 90s.

ALF’s story begins after this alien’s spaceship crash-landed in the garage of the Tanner’s, a typical suburban American family. Although his many antics often bring trouble for the entire family, ALF’s big heart quickly makes the Tanners fall in love with him, harboring and keeping him hidden from the U.S. government.

E.T.

Are we in the presence of the most famous film alien in history? While we might not be able to answer this question (the remaining entries on this list might very well be as beloved), E.T. is definitively a heavy contender for this highly-coveted title. It’s been over 40 years since this extraterrestrial’s only on-screen appearance, but he still remains as iconic as he ever was.

Steven Spielberg’s 1982 film tells the story of Elliot, a typical American boy who befriends a lovable alien stranded on Earth. Elliot, alongside his family and friends, helps E.T. go back home, leaving us with a few of the most memorable moments in cinematic history.

Not every alien on this list has to look weird: Leave it to the amazing Robin Williams to portray one of the most beloved TV aliens in history. "Mork and Mindy" shows the adventures of Mindy McConnell, an American teenager who befriends an alien simply known as "Mork from Ork."

Not many know that this now classic TV show was an offshoot of another beloved American show, "Happy Days." Williams's only appearance in a Happy Days episode impressed producers so much that they decided to give this TV legend his first chance.

Marvin the Martian

Marvin the Martian might be the first alien on this list to pose a threat to mankind, but don’t worry: His plans usually backfire in a spectacular fashion, usually thanks to a wisecracking rabbit or to a lisping duck with anger issues.

Originally voiced by the legendary Mel Blanc, perhaps what’s more memorable about Marvin is his unusual design: You wouldn’t expect a creature of outer space to sport a red unitard, green skirt, nor a fashionable broom on his helmet, right?

Chewbacca

If you had to describe Chewbacca to someone who had never seen the film, the image they would form in their head wouldn’t necessarily describe Han Solo’s partner in crime, right? After all, they would probably think of Chewie as some sort of huge and extremely adorable teddy bear, unaware of the danger they would be in if they called this iconic Wookie cute.

However, as ferocious as Chewbacca was to any Storm Trooper that dared to step in his way, he was also an extremely loyal and loving comrade to any of his many rebel friends. Few movie sounds are as memorable as Chewie’s deafening roar.

Xenomorph

First things first: In case you didn’t know, the titular alien species in the " Alien " film series does have a name. Well, sort of. These jet-black monstrosities are actually known as the Xenomorph . However, should you ask an etymology aficionado about what this Ancient Greek word actually means, the answer would simply be "an alien or strange creature." So, in a way, these creatures can simply be called "Aliens.".

In any case, few extraterrestrials have instilled so much fear into the hearts of moviegoers: Their razor-sharp claws, amazing strength, and acidic blood definitively make them one of the most dangerous creatures in film history. In fact, only one fictional alien species has been able to stand their ground against the vicious Xenomorphs and, as luck would have it, they are the next entry on this list!

Predator

Way before the 2001 movie "Alien vs Predator" pitted these two science-fiction juggernauts against one another, the Predator had already established itself as the deadliest hunter in the galaxy. This alien race lives for one thing and one thing only: To prove their skills by tracking and hunting down the most dangerous and exquisite creatures.

The 1987 film "Predator" introduced the world to this cold-blooded hunter by placing him in a terrifying environment: The film follows Vietnam War veteran Major Dutch (played by Arnold Arnold Schwarzenegger) and his efforts to escape the Predator that’s hunting them in the deep jungle. However, the second Predator film saw an even more unnerving scenario: The Predator hunting down prey in the streets of Los Angeles.

Mr. Spock

Is Mr. Spock on this list? It seems only logical. In a list almost entirely comprised of extraordinary and bizarre creatures, it only took a set of pointy ears to turn actor Leonard Nimoy into one of the most instantly recognizable fictional aliens in history.

Mr. Spock has been a staple of the Star Trek universe since the very first episode of the original show aired in the 1960s. Spock quickly became a fan favorite: His highly logical brain, combat skills and passion for science made him extremely interesting to TV audiences. Not only that, Nimoy’s deep voice and magnetic personality added to the depth of this character.

Mars Attacks!

When audiences saw Tim Burton’s 1996 black comedy "Mars Attack!," they were quickly enthralled by the menacing yet funny-looking Martians attacking our country. However, few of them knew that these aliens were actually much older, dating back to a 1960s trading card game produced by Topps.

The lore established by the trading card series and the film is pretty much the same: One day, our planet finds itself invaded by a race of Martians hell-bent on taking over our planet. While the Earth is first unable to defend against their superior technology, our tenacity and grit allow us to battle these hideous space invaders.

Superman

We’ll end this article with the last son of Krypton. Sometimes we tend to forget that Superman , a superhero believed by many to be the ultimate American icon, arrived on our planet as a baby from outer space. After his home planet was doomed, Kal-El’s biological father sent him far away across the galaxy, with his small vessel crash-landing into a small farm in Smallville, Kansas.

Baby Kal-El was found by Jonathan and Martha Kent, two farmers who instantly adopted him as their own child. Now known as Clark, the boy that would eventually become the "Man of Steel" found his powers at an early age, and set out to defend our world from all sorts of dangers.

Thor's Well, Oregon

Image: Eric Muhr

Imagine there is a huge, circular hole in the sea where water seems to fall endlessly into an abyss. Spooky, right? Well, this is what you'll see if you look at the incredible Thor's Well, located on the Oregon coast.

Despite its name, it's not a well but a large, bowl-shaped sinkhole situated on the rocky shore. When you see it, it gives the impression that the ocean is being drained away! The ocean waves flow in and out of the hole, creating a dancing water spectacle. But that's not all; the site is surrounded by rugged volcanic rock that becomes slippery and hazardous when wet. It feels almost like stepping into a scene from a fantasy movie.

Devil's Den, Florida

When it comes to spooky names, Devil's Den stands out. While its name might not sound very inviting—unless you’re a horror fan—this is actually an incredibly beautiful place with a charm that is hard to match.

Devil's Den is a prehistoric underground spring and cave system. Picture yourself walking through the state of Florida when suddenly you find a big, mysterious hole in the ground. When you look down, you discover a cave with a bright blue body of water inside. Scientists believe that the roof of an underground river collapsed here, exposing the water surface and creating what we now know as Devil's Den Spring.

If you haven't visited this spot yet, this is your invitation; you won't regret it!

Bisti/De-Na-Zin Wilderness, New Mexico

Bisti/De-Na-Zin Wilderness is an incredible landscape filled with reddish-purple rock formations on eroded terrain . The site has amazing geological structures sculpted from sedimentary rock.

While this scene looks like something out of a science fiction movie set on some distant planet, this extraordinary place is not only on Earth but also right here in northwestern New Mexico.

Want to know what its name means? Bisti and De-Na-Zin are Navajo words that can be translated to "a large area of shale hills" and "standing rock," respectively.

Bumpass Hell, California

Lassen Volcanic National Park in northeastern California has something to surprise visitors: a geothermal basin.

We're talking about Bumpass Hell, a place with a name that has an interesting history. This spot owes its name to Kern Bumpass, a miner who, in the 19th century, was one of the first to explore this little-known wonder. Bumpass suffered injuries and burns due to the geothermal activity, which gave rise to the ingenious name that the area has today.

What you see upon arrival is a series of steam vents reaching temperatures of up to 200°F , rising from bubbling hot springs. And as if all this weren't enough, Bumpass Hell is framed by the beautiful Cascade Mountains.

Havasu Falls, Arizona

While the Grand Canyon in northern Arizona is one of our country's best-known natural landmarks, it also holds a special spot that many overlook. Although a permit is required and access is a bit tricky, the effort is well worth it to find the beautiful Havasu Falls. The most common way to reach Havasu Falls is by hiking , but you can also get there by helicopter.

The waterfall is an impressive 100 feet high and splashes against the unique rocky backdrop. This spot is mesmerizing, and this fact is reflected in its name: Havasu translates to "blue-green water" in the Havasupai language.

Turnip Rock, Michigan

The Great Lakes are well-known for their beauty and size, but there's a hidden gem among them that has been overlooked for a long time.

Picture yourself standing on the shore of a lake and suddenly spotting a large rock formation that appears to be balancing on the water. If you experience this, you're probably in the state of Michigan, precisely standing by Lake Huron, witnessing the incredible formation called Turnip Rock.

Its name comes from its strange shape: over the years, the action of the waves has eroded the base of the rock, making it narrow while leaving the top wide. As a result, the rock now resembles a giant turnip. The best way to reach this site is by kayak, so if you like that activity, Michigan is the perfect place for you!

Apostle Islands Sea Caves, Wisconsin

Wisconsin boasts some of the most beautiful natural areas and holds unexpected scenery.

If you enjoy museums and art, don't miss Apostle Islands Sea Caves in Wisconsin. Here, nature is the main work of art, with water as the star sculptor!

In this spot, the water has drastically affected the cliffs, carving out wonderful rock formations with incredible shapes. However, all of this becomes even more amazing in winter when the site is covered with ice water and adorned with icicles hanging like spikes!

Craters of the Moon National Monument, Idaho

If you are someone who has always dreamed of traveling to space and stepping foot on the moon , this place might become your new favorite spot.

While it's not actually in outer space, Craters of the Moon National Monument in Idaho makes you feel as if you were there. As the name suggests, the landscape here resembles lunar craters. These pits and fissures in the dark, hardened ground are the result of volcanic activity that has occurred in the area over the past 15,000 years.

If you enjoy hiking, exploring caves, and taking in spectacular views, don’t miss the chance to visit this remarkable place!

Lost River Cave, Kentucky

As if descending into the dark depths of a cave weren’t enough, imagine the sensation of navigating an underground river! If you're not afraid of that scenario, then you can visit Lost River Cave in Kentucky.

After passing through a dramatic entrance, you'll enter the cave system, a mysterious world adorned with stalactites and stalagmites that decorate the entire space. But the highlight is the river flowing through it. Visitors can experience this adventure by taking a boat ride along the underground river with other guests. It’s an experience you definitely won't want to miss!

Providence Canyon, Georgia

Yes, the Grand Canyon is absolutely impressive and beautiful, but it's not the only canyon in our country. Right here in the US, we also have the Providence Canyon, located in southwestern Georgia.

Sometimes called "Georgia's Grand Canyon," this stunning place is approximately 120 miles southwest of Atlanta and covers about 1,000 acres. The rock formations here delight visitors with a varied color palette, ranging from pink to red, orange, and even purple.

In addition, the canyon's depth ranges from 15 to 50 feet, offering magnificent views to enjoy during the hike. If you love to explore, make sure to visit Georgia!

More than eight million people call New York City home. That means roughly one out of every 38 Americans lives within its five boroughs. It helps explain why the city feels endlessly busy and why every neighborhood seems to have its own rhythm, personality, and pace. The City that Never Sleeps feels like the right nickname, right?

Statue of Liberty

The Statue of Liberty arrived from France as a gift celebrating American independence. She did not come in one piece. Instead, the statue arrived in 214 crates, each containing 350 separate parts, and took four months to assembl e. Even symbols of freedom sometimes require instructions, you know?

New York Public Library

The New York Public Library system holds more than 50 million books and items. It is second in the United States, only to the Library of Congress, and ranks third worldwide .

United Nations headquarters

The United Nations established its headquarters in New York City in 1952 following World War II. Since then, diplomats from nearly every country have gathered here to debate, negotiate, and occasionally argue. Few city blocks anywhere else host quite so many global decisions.

Brooklyn borough size

Brooklyn alone would rank as the fourth-largest city in the United States if it stood on its own. Queens would claim the same spot as well. Together, they show just how massive New York City really is, even when broken into boroughs.

Times Square naming

Image: James Ting

Times Square did not always have its famous name. It was once called Longacre Square until The New York Times moved its headquarters there in 1904. The name stuck, the lights followed, and the area became one of the most recognizable intersections in the world.

Chinatown population

More Chinese people live in New York City than in any other city outside Asia. This influence shapes neighborhoods, food scenes, businesses, and traditions across the city. It is one more reason New York feels like many worlds packed into one place .

Believe it or not, pinball machines were once against the law in New York City. Back in 1942, city leaders viewed the game as a form of gambling , and Mayor Fiorello LaGuardia ordered it banned. For more than 30 years, pinball disappeared from public view until the rule was finally lifted in 1976.

Hidden beneath the elegant Waldorf Astoria Hotel is a little-known train platform called Track 61. According to long-standing stories, President Franklin D. Roosevelt used it to arrive and leave discreetly, away from crowds and cameras. The platform is no longer active today , but knowing it exists adds a layer of mystery to an already legendary building.
