Though he was not as well known to the general public as contemporaries like Isaac Asimov or Ray Bradbury, Sturgeon gained recognition among readers of mid-20th-century science fiction anthologies. At the height of his popularity in the 1950s, he was the most anthologized English-language author alive.

Some of his more popular works include The Call of Cthulhu, At the Mountains of Madness, The Shadow over Innsmouth , and The Shadow Out of Time . The central theme of his books is cosmicism, a theory dictating that "there is no recognizable divine presence, such as a god, in the universe, and that humans are particularly insignificant in the larger scheme of intergalactic existence."

ALF

Image: Erik Mclean

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.

Mork

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.

4

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?

5

Chewbacca

Image: Kadyn Pierce

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.

6

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

Image: Esteban López

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.

California

California is famous for its grand sights, but few can compete with Methuselah, a Great Basin bristlecone pine more than 4,800 years old, widely considered the oldest known tree on Earth.

Beyond its ancient forests, the state also shines in pop-culture records: one of Kurt Cobain’s guitars sold in Los Angeles for over $6 million, becoming the most expensive guitar ever auctioned. California is also home to eye-catching personal records, including the world’s longest female arm hair and the largest male afro. From timeless trees to memorable modern oddities, California’s record list is full of true West Coast flair.

Nevada knows how to entertain…and break records along the way! Las Vegas boasts the highest density of hotel rooms in the world, along with an unmatched lineup of themed resorts that range from ancient pyramids to miniature European cities.

The Bellagio holds the record for the most fountains in a hotel, and the Venetian shines with the world’s largest polished-marble floor area. The city also has more resident magicians than anywhere else and hosts thousands of weddings each month. In Nevada, the show is always bigger, brighter, and endlessly jaw-dropping.

The Gem State holds some of the country’s most lighthearted records. Beard enthusiast Joel Strasser turned facial hair into a full-time hobby. He has tucked thousands of everyday objects into his whiskers, from 3,500 toothpicks to 600 barbecue skewers.

Idaho is also home to record-setter David Rush, known for everything from lightning-fast lemon-juice sipping to catching marshmallows fired from a homemade catapult. And on the scientific side, the University of Idaho helped welcome Idaho Gem, the first cloned mule in history.

Arizona

Arizona loves a good spectacle. In Phoenix, an exhibition opening once used a pair of 10-foot scissors —the largest in the world— to cut the ribbon in style. Down in Yuma, sunshine reigns supreme: the city enjoys about 91% of all possible daylight hours each year, adding up to more than 4,000 hours of bright, warm weather.

The state also embraces playful oddities, including its own "Poozeum", the world’s largest collection of fossilized… well, you can guess the rest. And at the Phoenix Zoo, visitors can even meet Nikki, the world’s oldest mandrill, adding another unique distinction to Arizona’s lineup of record-setters.

Georgia blends big art with big sports. The state is home to the world’s largest tattoo artwork —a massive 79-plus square-foot piece created by two Atlanta studios using a special silicone canvas and more than $30,000 in materials.

On the athletic side, Georgia Tech once set the highest football score ever recorded, finishing an unforgettable 222-0 game back in 1916. From oversized art to record-setting touchdowns, Georgia knows how to leave a bold, lasting impression.

Alaska

Up north, "large" takes on a whole new meaning. Alaska’s Pribilof Islands host the biggest northern fur seal colony on Earth, with close to a million animals gathering during peak seasons.

The state also celebrates remarkable feats of endurance: a tagged bar-tailed godwit flew more than 8,400 miles nonstop from Alaska to Tasmania, setting a record for the longest continuous bird migration. And in the Arctic interior, the Great Kobuk Sand Dunes stretch across nearly 24 square miles —the largest active dune field in the region. Even in a land known for ice and mountains, Alaska proves it can go big in surprising ways.

7

Delaware

Delaware may be tiny on the map, but it knows how to draw a crowd. The state is home to 11 record holders, including the World's Largest Doctor's Bag Monument.

Delaware State University once gathered 1,709 people waving foam fingers at the same time, and another huge group buzzing handheld buzzers together. The state is also home to a towering 36-foot stack of cardboard boxes called the "Leaning Tower of Pizza." Small state, big personality.

8

Hawaii

Hawaii’s natural wonders reach record heights, and many of them are straight from the islands’ own landscape. Kīlauea is recognized as the world’s most active volcano, with decades of steady activity and a name that fittingly means "spewing."

The islands also celebrate remarkable achievements on the ocean: off Oahu, Australian surfer Laura Enever rode an astonishing 43.6-foot paddle-in wave, the largest ever recorded for a woman.

9

Illinois

Illinois loves to go big, and it shows in all kinds of creative ways. In the small town of Casey, visitors can stand beneath a giant rocking chair more than 56 feet tall —one of the state’s many oversized roadside attractions.

The Prairie State also stirred up the world’s largest jar of spread, using more than a ton of peaches and tomatoes in a three-day cooking marathon. Are you waiting for something more extreme? An Illinois native set the record for the fastest clapping ever recorded, reaching an incredible 804 claps in one minute.

10

Alabama

Alabama has a special talent for turning simple moments into big record-breakers. Here you’ll find the largest bubblegum bubble ever blown —a bright 20-inch sphere made from just three pieces of gum and plenty of practice.

The state also celebrated the Apollo 11 anniversary by launching nearly 5,000 model rockets at once, filling the sky with a burst of color. Alabama is home to more than 50 record holders, including inspiring stories like Curtis Means’, the world’s most premature baby to thrive and grow. If you enjoy bold, cheerful achievements, Alabama delivers them in generous size.

11

Arkansas

The Natural State mixes small-town charm with some truly memorable oddities. Arkansas was once home to Lurch, the African watusi steer famous for having the largest horn circumference ever measured —an incredible 37.5 inches around.

Arkansas also wears its heart on its sleeve: a statewide effort gathered more than 81,000 pounds of pet food in just 24 hours, setting a cheerful charity record. And for pure determination, a young Arkansan even held a deep squat for nearly three hours. In Arkansas, generosity and eye-catching achievements go hand in hand.

12

Florida

Florida takes "large" to heart. The Sunshine State is home to the world’s longest limousine, a restored 100 ft 1.5 in cruiser with room for 72 passengers —nearly three times the length of an ordinary stretch limo!

Florida also knows how to put on a show: Miami hosted the first-ever pay-per-view pillow fight, complete with pro fighters and custom-made pillows; in Bradenton, a Monster Jam driver set two eye-popping records for the most consecutive spins in a monster truck.
