The universe revealed

Mind-blowing truths: 10 space facts you won’t believe are real

Did you know that everything we know about the universe makes up only about 5% of it? Even so, there’s still much that might surprise you. On some planets, a year is shorter than a day, while on others it can literally rain diamonds. From the smell of comets to the color of Mars’ sunsets, here are 10 incredible facts about the universe you probably didn’t know.

Perhaps if the Weather Girls had been born on Neptune or Uranus, their famous hit might have had a very different title, because something extraordinary may happen on these planets: it can rain diamonds! The immense pressures in their atmospheres can compress carbon into diamond crystals, which then sink deeper into the planets’ interiors.

If you are reading this at night, step out into your backyard and take a look at the Moon. While we often assume everyone sees the Moon the same way, that’s not true. In fact, the Moon appears "upside down" in the Southern Hemisphere. This happens because your perspective changes relative to the Moon: in the Northern Hemisphere, you’re viewing it from "above" the equator, while in the Southern Hemisphere, observers see it from "below."

Saturn, the second-largest planet in our solar system, has a diameter of about 74,897 miles, making it roughly nine times wider than Earth. Surprisingly, it’s theoretically possible for Saturn to float on water... if only you could find an ocean big enough! This isn’t because of its size, but because of its composition: the planet is mostly made of hydrogen and helium, extremely light gases that make Saturn less dense than water.

Remember that time you got distracted and the steak on the stove got a little burnt? Surprisingly, the smell in your kitchen isn’t too different from what astronauts report after spacewalks. Scientists have noticed that objects returning from space, especially those exposed to the vacuum outside the spacecraft, carry a distinctive odor often described as burnt steak or welding fumes.

It takes Earth about 365 days to orbit the Sun, which is why our year is that long. A day, on the other hand, lasts just 24 hours because that’s how long it takes Earth to complete one full rotation on its axis. But on Venus, things work very differently. A single day on Venus (the time it takes to rotate once on its axis) is about 243 Earth days, making its rotation extremely slow. Surprisingly, a year on Venus is shorter than its day, because it only takes about 225 Earth days for Venus to orbit the Sun. Incredible, isn’t it?

Since we see the Moon in the sky nearly every night, it’s easy to forget that it’s a giant rock floating far away in space. In fact, the distance between Earth and the Moon is about 238,900 miles, so vast that, in theory, you could line up all the other planets in our solar system across that gap!

Mars is famously called the "Red Planet" because its surface is covered in iron oxide (rust), giving it a reddish appearance from afar. But if you were standing on Mars at sunset, you’d get a surprise: unlike Earth’s warm orange, gold, and pink hues, Martian sunsets appear blue. This happens because the planet’s thin, dusty atmosphere scatters sunlight differently, allowing blue light to dominate near the Sun at sunset.

Comets, made of ice, dust, and frozen gases, are truly spectacular to see. But if you could smell them, they might not be so pleasant. As a comet nears the Sun, its ices sublimate, turning directly from solid to gas and releasing various compounds. Among these are sulfur-containing gases, which give off a strong rotten-egg smell.

Scientists can estimate the number of stars in the universe using observations and projections. Astronomers observe a small patch of the sky, count the galaxies and stars there, and then extrapolate those numbers to the entire observable universe. While Earth has an incredible number of sand grains, these calculations suggest that there are far more stars than grains of sand. If you're not impressed yet, remember that many of those stars are much larger than any planet!

If the last fact shocked you, this one will totally blow your mind. While our galaxy has far fewer stars than the entire observable universe, you might be surprised to learn that trees on Earth actually outnumber the stars in the Milky Way. That’s right! Scientists estimate there are roughly 3 trillion trees on our planet, while the Milky Way contains only about 100 to 400 billion stars.

No, Golden Retrievers weren't bred to fetch gold: Dog breed names 101

Do you love dogs? From royal companions to fearless hunters and from German badger dogs to barkless African hounds, the names of our favorite breeds often hold surprising stories. Whether you’re a fan of the stoic Mastiff, the sassy Poodle, or the majestic Husky, there’s a tale behind each name that might surprise you. Let’s dig in!

The beautiful, blue-eyed Husky is inseparable from dog-sledding lore. The breed’s name evolved from the word "Eskimo."

English sailors once slurred "Eskimo" into "Uskee" or "Huskemaw," which eventually transformed into "Husky."

What’s not to love about wiener dogs? Their original name, however, refers not to their iconic sausage shape but to the purpose for which the breed was developed.

Dachshunds were bred to hunt badgers and other burrowing animals, with their long bodies and short legs making them ideal for digging into tunnels. The name is a German compound of Dachs (badger) and Hund (dog), meaning "badger dog."

There are three beloved varieties of Schnauzer—miniature, standard, and giant—and each has had its moment in pop culture.

The breed takes its name from its distinctive "mustache" or schnauze (snout) in German, literally meaning "snouter" or "muzzle." Originally, Schnauzers were used as rat-catchers and guard dogs in Germany.

Often portrayed as guard dogs or police K-9s in film, Dobermans were named after Karl Friedrich Louis Dobermann, a 19th-century German tax collector who developed the breed as a loyal and protective companion for his dangerous rounds.

Queen Elizabeth II’s beloved Welsh Corgis made the breed internationally famous. In Welsh, cor means "dwarf" and gi (a soft mutation of ci) means "dog," so Corgi translates to "dwarf dog." Indeed, the breed originated in Wales, where it was used for herding cattle by nipping at their heels. Over time, Corgis also became a cultural symbol of British royalty.

Known as the "barkless dog" of Central Africa—because of its unique larynx structure, which produces a yodel-like sound (baroo) instead of a bark—the name "Basenji" comes from a Bantu language and roughly translates to "village dog" or "bush thing." The breed is ancient and was used for hunting in the Congo.

Did you know the Labrador Retriever has been America’s most popular dog breed for decades? Despite its name, the breed did not originate in Labrador but in Newfoundland.

It was called "Labrador" because British breeders associated the dogs with the Labrador Sea and the nearby region, while "Retriever" refers to the breed’s role in hunting.

So, did Golden Retrievers retrieve gold? Short answer: no. Like Labradors, they were bred to retrieve game for hunters, but the "golden" part of their name refers to their beautiful coat.

The breed was developed in Scotland in the 19th century by crossing several breeds to create an obedient, water-loving gun dog.

Snoopy is perhaps the most famous Beagle out there, even though we only saw him in black and white.

The origin of this beloved breed’s name is debated. It may derive from the Old French begueule, meaning "open throat," a nod to their baying howls. Others trace it to Celtic or Old English words meaning "small."

Always pampered and impeccably groomed! If the term "Poodle" has always reminded you of "puddles," you are not far off. The name comes from the German Pudel or Pudelin, meaning "to splash in water." Poodles were originally bred as water retrievers, so their name reflects this aquatic work.

Pugs’ features and expressive faces have made them a source of comic relief in pop culture. There is no consensus about the origin of their name, however.

Some say that it derives from the Latin pugnus, meaning "fist," perhaps referencing their squished, fist-like face. Others say that in 18th-century England, "pug" was also a term of endearment for something small and compact-looking.

Athletic, energetic, and full of protective instincts, Boxers are true family guardians. But why the name?

It is thought to come from the breed’s tendency to use its front paws in play, like a boxer in the ring. Another theory links the name to the German word Boxl, a nickname for the breed in Bavaria.

As calm and noble as they are huge, Mastiffs were named after the Old French mastin or the Latin mansuetus, meaning "tame" or "domesticated." Despite their imposing size, Mastiffs were bred to guard homes and estates while remaining loyal and gentle with their owners.
