00:00For years, scientists have been struggling to explain bizarre sounds, some repeating,
00:06some heard only once, that come from the dark depths of the ocean.
00:10From bewildering hums to worrying bloops, the water transmits outlandish acoustic phenomena.
00:17One of these mysterious noises got named the upsweep.
00:21For the first time, this long train of sounds was registered in 1991 in the Pacific Ocean.
00:28One of the most unusual things about this signal is that it keeps changing, as if trying to confuse researchers
00:35even more.
00:37Like some unearthly howl, it varies from high to low frequencies and then back again,
00:42and you can hear it better in the spring and fall than in the winter and summer.
00:48Why the upsweep?
00:50It's simple. The sound travels from the bottom of the ocean towards its surface, as if sweeping up.
00:57Scientists do have a theory explaining this phenomenon, the activity of undersea volcanoes.
01:02Hot lava pouring into ice-cold ocean water could theoretically create such noises, but there's no proof found yet.
01:10Plus, the sound has been declining since 1991, even though it can still be detected.
01:19The bloop is the name given to an ultra-low frequency and incredibly powerful underwater sound
01:25that was recorded in 1997 by the U.S. National Oceanic and Atmospheric Administration.
01:31The bloop continued for approximately one minute.
01:34Having started from a low rumble, it gradually rose in frequency.
01:38It also kind of mimicked the noise created by marine animals, but its volume was so great
01:43that no living creature known to science could have made it.
01:47When the bloop occurred, underwater microphones managed to record it from a distance of 3,000 miles away.
01:55Rumor has it that the noise might have something to do with the fictional half-octopus monster Cthulhu
02:01or some other colossal deep-water creature.
02:04But if you don't believe in monsters, science has another explanation.
02:09Iceberg fracturing.
02:10The thing is that icequakes recorded in the Scotia Sea resemble the mysterious bloop a bit too much for it
02:17to be a coincidence.
02:20The whistle resembles this annoying sound when a kettle of boiling water is telling you it's time to make a
02:26cup of tea.
02:26But even though it may not be as blood-curdling as some other bizarre ocean sounds, it doesn't make it
02:32any less mysterious.
02:34Plus, the whistle is very elusive.
02:38In 1997, only one underwater microphone was able to pick it up,
02:43and therefore, researchers didn't manage to pinpoint the source of the noise.
02:48The most likely cause of the sound is an eruption of one of the submarine volcanoes.
02:54Have you ever heard of Julia?
02:57No, not your neighbor.
02:59I'm talking about this otherworldly sound.
03:02Listen to it.
03:06It was recorded in 1999 by the U.S. National Oceanic and Atmospheric Administration.
03:12The source of the sound was most likely a large iceberg that ran aground somewhere in Antarctica.
03:18The sound was so loud that it was heard over a huge territory, and its duration was about 2 minutes
03:25and 43 seconds.
03:29Slow down.
03:30That's the name given to a sound recorded in 1997 in the equatorial Pacific Ocean.
03:42The sound was called this way because it slowly decreased in frequency over 7 minutes or so.
03:48It's been picked out a few more times since it was recorded for the first time.
03:53The source of the sound isn't very mysterious.
03:56Most likely, it was produced by a massive iceberg that became grounded in Antarctica,
04:00or it was caused by moving ice.
04:02By that, I mean the friction produced by a large ice sheet moving over land.
04:10The loneliest whale sound is often called the 52 hertz whale
04:14because the animal that creates it calls at a unique for these creatures frequency.
04:20When you listen to this sound, it sounds like a low bass note.
04:23At the same time, it's much higher than the normal frequency of the whale call,
04:27which rings between 10 and 40 hertz.
04:31Interestingly, scientists have been listening to the world's loneliest whale for decades,
04:36but haven't managed to figure out its precise location.
04:39Nobody knows whether the mammal is male or female,
04:43what species it is, or if the animal is still alive.
04:47After all, for the last time, its call was recorded in 2004.
04:55Earth-shaking booming sounds have been reverberating off some parts of North Carolina
05:00for more than 150 years.
05:03Called Seneca guns, they're most often heard near the coast.
05:07The sounds are so powerful that they often rattle window panes
05:11and sometimes vibrate entire buildings.
05:14They can last from 1 to almost 10 seconds.
05:18Even though scientists haven't cracked this mystery yet, there are some theories.
05:23They range from earthquakes to severe distant storms and quarry blasts.
05:27But even though the ground trembles every time the phenomenon occurs,
05:31no seismic activity coincides with these events.
05:36So far, scientists have come to the conclusion that the mysterious sounds happen in the atmosphere,
05:41not on or under the surface of our planet.
05:44If this theory is true, bolides might be the answer.
05:47These extremely bright meteors often explode once they enter Earth's atmosphere.
05:52Or, Seneca guns might be born in the ocean.
05:56Sometimes, when enormous waves collide far away from the shore,
05:59you can hear it, even if you're nowhere near the coast.
06:03Seneca guns are a type of skyquakes.
06:06You don't need to travel to a particular part of the world to hear one of those.
06:10Mysterious sonic booms ramble from the sky everywhere,
06:13from the US to India and Japan.
06:17Just like Seneca guns, this sound phenomenon occurs mostly near the coast or a big body of water.
06:24Rattling glassware and windows in the nearby houses,
06:27skyquakes could be connected with ultra-fast airplanes breaking the sound barrier.
06:31But, people started hearing the first skyquakes in 1824.
06:36The theories trying to explain this phenomenon include sand dunes shifting,
06:41meteors entering the atmosphere,
06:43distant volcanoes erupting,
06:45Earth's crust cracking during earthquakes,
06:47and even gas bursting out of underground vents in the sea or lake bottom.
07:03In different countries all over the world,
07:05people get paralyzed with fear after hearing otherworldly trumpet sounds
07:09that seem to be coming from the sky.
07:11The inhabitants of the US, Canada, Australia, Germany, and the Philippines
07:16have already heard this hair-raising noise since it was first recorded in 2008.
07:22These sounds are sometimes called the sound of apocalypse.
07:26And although until recently, nobody could understand the origin of the sounds,
07:31NASA claims that there is nothing to be afraid of.
07:34The noise can be coming from our own planet.
07:37Usually, it's quiet and thus inaudible to the human ear.
07:41But when it gets louder,
07:43the outcome is the very trumpet sounds that scare people all over the world.
07:49Bristol Hum started in the 1970s
07:51when hundreds of Bristol inhabitants began to talk about a bizarre noise audible only at night.
07:57The noise was a low-level hum,
08:00and nobody could identify or trace the source of the sound.
08:03But the strangest thing about the noise was that one day,
08:06it stopped as abruptly as it started,
08:09but not before people in other towns across Britain reported hearing similar sounds.
08:14Some time ago, the mysterious sound returned.
08:17In 2015, a group of French scientists claimed that they had solved the mystery of the Bristol Hum.
08:23They stated that the culprit was ocean waves that made the ocean floor vibrate.
08:28But while it was all good and well,
08:30it didn't explain why the sound was around for only several years or why it chose to return.
08:36If you ever come to the town of Taos in New Mexico,
08:40don't let another strange and unexplained phenomenon send you running for the hills.
08:44This phenomenon is a faint, low-frequency hum
08:48ringing in the desert air and grating on your nerves.
08:51Even stranger, only 2% of people who live in Taos hear this noise.
08:56But for those who do, it's unstoppable torture.
09:00On top of that, everyone describes the sound in a different way,
09:03from a quiet whirr to an eerie hum or even persistent buzz.
09:08And while some people believe that the Taos hum is the result of unusual acoustics,
09:13the others suspect a bad case of mass hysteria.
09:17No one has located the origin of the hum yet.
09:22Sing with me.
09:23Under the sea, darling it's better, on where it's drier, take it from me.
09:28Okay, okay, I know these are not the correct lyrics to this famous Disney song, but hear me out.
09:33The deep sea is not all about singing mermaids and dancing crabs.
09:38It's actually filled with monster-like creatures that'll give you nightmares.
09:41So, if you're ready to meet them, grab your scuba gear and let's dive into the deep, mysterious waters to
09:48discover their fascinating and scary world.
09:51With its menacing appearance, one could call this fishy the vampire of the sea.
09:56While named for their disproportionately large, razor-sharp fangs protruding from their mouth,
10:03fang-tooths are actually quite small and harmless to humans.
10:06These choppers are actually more for catching prey than causing trouble.
10:10So, there's no need to panic if you see one.
10:13And you'll be even more relieved to know that it's kind of unlikely for you to come across a fang
10:18-tooth,
10:18since they are among the deepest living fish.
10:21A regular day in the life of a fang-tooth looks like this.
10:25By day, they prefer to remain in the gloomy depths.
10:28Me too, fishies, me too.
10:30It's only towards the evening that they migrate toward the surface to have a feast under starlight.
10:36Ah, how romantic.
10:38And by daybreak, they return to the deep.
10:40What a chill schedule, am I right?
10:43So, as you can tell from their daily routine,
10:45fang-tooths are among the more active deep-sea fishes.
10:49And by that I mean they seek out their food rather than just sitting and waiting.
10:54And thanks to their oversized teeth and mouth,
10:57hey, I can relate,
10:58they're able to attack prey that are even larger than themselves,
11:02which is very important in the very large, food-poor deep sea.
11:06Fitting to their environment, common fang-tooths are dark-colored,
11:10either solid brown or black.
11:12And unlike most deep-sea fishes, they do not have light-producing organs or cells
11:17to communicate with each other or to attract their prey.
11:21Instead, they rely heavily on their sense of smell,
11:24in addition to making use of even the slightest bit of sunlight that makes it down to the depths.
11:29This light doesn't help them to see in any way,
11:32but it may be enough for potential prey to cast a shadow as they pass overhead,
11:37which lets fang-tooths know they're around.
11:40Now, here's one hilarious fun fact before we move on to the next creature.
11:44Fang-tooths can never close their mouths because of their huge mouths and long teeth.
11:49But you know what?
11:50I would bet maybe 500 bucks that my orthodontist would claim he could fix that too.
11:57Our next horrific deep-sea animal is as real as a kraken can get.
12:02Giant squid, which actually did inspire the legends of the kraken,
12:06live up to their name. The largest one, ever recorded by scientists, was almost 59 feet long.
12:12It also probably weighed nearly a ton.
12:15You would think such a massive animal wouldn't be hard to miss.
12:19But since giant squid live deep underwater, they are difficult to come by.
12:24Giant squid, along with their cousin, the colossal squid,
12:27yep, they are different, have the largest eyes in the animal kingdom.
12:31They're somewhere around 10 inches in diameter. In other words, they are around the size of dinner
12:37plates. Peek-a-boo!
12:39Having such large eyes allows them to detect objects in the lightless depths of the ocean,
12:44where most other animals would see nothing. Not a zippo.
12:48Giant squids have eight arms and two long feeding tentacles that help them seize their prey.
12:54These tentacles are tipped with hundreds of powerful sharp teeth,
12:58and are often double the length of their body. This helps them to snatch prey up to 33 feet away.
13:04Hey there, come a little closer!
13:07Most of what we know about giant squids come from those that floated to the surface
13:12and were found by fishermen. After years of research, it was only in 2012 that a group of
13:18scientists were able to successfully film a giant squid in its natural habitat for the first time.
13:24Yet again, the giant squid continues to remain largely a mystery due to their inhospitable deep-sea
13:31habitat. And maybe they're shy!
13:34Speaking of squids, this species is basically the space creature of the ocean.
13:39So, it's only been about 20 years since the Big Fin squid family was officially described by scientists.
13:45And there are still plenty of facts about them that are yet to be discovered.
13:50However, the Big Fin squid sightings as deep as 20,000 feet below the surface
13:55suggest that they can live deeper than any other known squid.
13:59You know what? Let's scratch the word space creature and call them the disco dancers of the deep sea
14:05to make things less scary. Because of their long, slender arms,
14:09adorned with extravagant rib-like fins, kind of make them look like they're ready to hit the dance floor.
14:15Anyway, these boogie arms and tentacles are estimated to max out at just under 30 feet.
14:22Aside from the estimations, though, the largest known Big Fin squid was actually 21 feet long,
14:28with 20 feet of that being its arms and tentacles.
14:31How exactly a Big Fin squid uses them is still unknown.
14:35But scientists think they like to use them to trap prey that bump into them
14:39as they hang down in the water below their body or drag along the seafloor.
14:44There are only around a dozen confirmed Big Fin squid sightings worldwide,
14:48so you can just relax. Because the chances of you getting hugged by a Big Fin squid
14:54are close to impossible. But I can't guarantee anything regarding your nightmares.
15:00Now, these are not one of your regular Jaws sharks. Let's start with the most strange fact
15:06about a frilled shark. It's considered a living fossil because of its primitive anatomic traits.
15:12That actually makes more sense once you learn that this species has been around for 80-some
15:18million years. So I have both good news and bad news. Frilled sharks live in the open ocean and spend
15:25much of their time in deep, dark waters far below the surface. However, they do feed at the surface
15:31of the ocean at night. When hunting food, they move like an eel, bending and lunging to capture
15:37their prey. And they can actually swallow it as whole, even if it is larger than their own size.
15:43This is all thanks to their long and flexible Jaws, which are equipped with 300 recurve needle-like teeth.
15:51Okay, I am somewhat freaked out now. Unlike the rest of the deep-sea creatures I've talked about,
15:57frilled sharks might sometimes accidentally get caught in nets. So if fishing is your thing,
16:03beware!
16:05This telescope won't help you see the stars and the planets. With its protruding eyes and
16:10elongated body, this little swimmer looks like it's wearing a pair of underwater binoculars.
16:15Hence the name, the telescope fish.
16:18Found in cold, deep, tropical to subtropical waters worldwide, they're known to be the species that
16:24undergoes one of the most drastic transformations in fishes. When the first larva was described in
16:311954, it was believed to be a new species rather than the larva of a telescope fish that were known
16:38to science since 1901. Despite the fact that they are only around 6 to 8 inches long, they're able to
16:44latch onto snacks that are bigger than their own size. That is thanks to their massive and highly
16:50stretching Jaws, making up most of the size of their head. These large prey are then folded in
16:56half to fit in their expandable stomach. In 1925, scientists found a 5.5-inch-long fish inside the
17:05stomach of a 3-inch-long telescope fish, which they described as neatly folded. Despite all this,
17:11their cylindrical tube-shaped eyes are still the most fascinating and bizarre features of telescope
17:17fishes. Their specific shape increases light collection to help them detect their prey's weak
17:23bioluminescence even from a distance. But although their eyes are good for seeing things in the twilight,
17:29they're especially great at seeing silhouettes from below. That's why they orient themselves vertically
17:35in the water. Now, I have to admit, they look kind of cute if you ask me. Sort of like
17:40uglier
17:41versions of minions. Yeah, right? Imagine a world where instead of water, the oceans are made of
17:48methane. Yeah, that's right. Instead of swimming in H2O, you'd be paddling around in CH4. It's like
17:56Mother Nature's version of a fizzy drink. Such oceans actually exist on one of Saturn's moons
18:03clouds called Titan. In fact, the methane and ethane on Titan play a similar role to the water
18:10on Earth. They cycle through the atmosphere and form clouds that eventually rain down onto the surface.
18:18They were discovered by the Cassini-Huygen space probe. And apparently, our entire planet's oil
18:24reserves could fit in one of Titan's puddles. Even the desert sand dunes on Titan have more organics
18:31than all of Earth's coal reserves. Who knew that Titan was the place to go if you're ever in need
18:36of
18:37fuel for your car? Now, obviously, there are some things that distinguish methane lakes from our
18:44water ones. First, the temperature on Titan is around negative 290 degrees Fahrenheit. It's like
18:53taking a dip in a giant glass of liquid nitrogen. Not exactly ideal for a beach day, is it?
19:01Methane is also less dense than water. So, if you were to go swimming in such an ocean,
19:07you'd float like a balloon. On the bright side, it would make doing the backstroke a lot easier.
19:14Next, while water waves can be pretty majestic, unfortunately, we can't ride any on Titan.
19:21Cassini didn't detect any big waves there. Maybe it's due to low seasonal winds,
19:26or the fact that some of the lakes are much smaller than Earth's lakes, but we don't know for sure.
19:34Also, I know what you're thinking. If the oceans are made of methane, could you set them on fire?
19:39Technically, yes. Methane is a highly flammable gas. So, if you were to light a match in a methane ocean,
19:46you'd get a pretty impressive but dangerous blaze.
19:52So, given all these differences, the question arises, what would a planet with such oceans look like?
19:58Well, we can make some guesses by looking at Titan.
20:03First of all, its atmosphere, composed primarily of methane, would be incredibly thick.
20:09Titan's atmosphere reaches nearly 370 miles into space,
20:13and the atmospheric pressure there is 60% greater than Earth's.
20:18So, if you ever wanted to experience the feeling of swimming super deep in the ocean,
20:23now's your chance.
20:26Also, methane is a powerful greenhouse gas that traps the sun's heat really well.
20:32That's why our planet would warm up faster than a sauna.
20:35You may ask, why is it so cold on Titan then?
20:38This is because this moon is very far from the sun, and light doesn't reach it well.
20:44But if we place our planet somewhere in the middle, then the temperature may even be quite comfortable.
20:52Actually, methane oceans on a planet could really spice up the climate.
20:57The planet would be a breeding ground for methane clouds.
21:00Just like on Titan, it could form an orange-colored haze, or smog,
21:05that would make our planet look like a real mystery.
21:08It would be difficult to see us from space without some special telescopes.
21:14And let's not forget about methane storms.
21:17They would also occasionally drench the surface, so remember to bring your umbrella.
21:21But, hey, at least the heavy, carbon-rich compounds would make for some pretty sweet dune fields.
21:29And finally, the most important difference.
21:32While water oceans on Earth are teeming with all sorts of creatures,
21:35we're not sure if there's any life in methane oceans on Titan.
21:40If there is, they'd have to be pretty tough to survive in such extreme conditions.
21:47So, if life on such a planet exists, it would be very different from what we're used to seeing on
21:52Earth.
21:53For example, microbes might be able to handle it.
21:56These tiny resilient creatures can survive in a wide range of environments, including extreme ones.
22:02So, it's possible that microbial life could exist in methane oceans.
22:09And what about us and animals?
22:12Well, scientist Robert Zubrin thinks that Titan might be the perfect place for humans to colonize in our solar system.
22:19According to him, this little moon has everything we need to survive and thrive.
22:24And if it's possible on that moon, then it could work with a planet, too.
22:30For starters, we'd need some oxygen to breathe.
22:34We could use nitrogen and methane in the atmosphere to create breathable air and rocket fuel.
22:39We could also use these elements to make some fertilizers and grow plants.
22:46Next up, we'd need water.
22:48Since the oceans are made of methane, we can't exactly drink them.
22:52We'd need to find or create sources of water.
22:55Scientists believe that it actually may be hidden below the surface on Titan, together with some ammonia.
23:01We could use it to drink or create even more oxygen.
23:07So, with all of these resources, we could create a self-sustaining colony, even in a place with methane oceans.
23:15Piece of cake!
23:18Although, there are always alternatives.
23:21Maybe we could become methane breathers.
23:24Evolve into organisms that use methane instead of oxygen.
23:28For example, we could get some large lungs, because we'd have to inhale a much larger volume of air.
23:34Since methane is less dense than oxygen.
23:37But, this is pure sci-fi.
23:41Methane oceans are not the only unusual oceans in space.
23:45It turns out that seas on diamond planets may be even weirder.
23:51Take WASP-12b, for example.
23:54This exoplanet, located about 1,200 light-years away, might have oceans of tar.
24:01That's right, tar.
24:02The planet has more carbon than oxygen.
24:05Which means its crust is probably made of things like diamond and graphite,
24:10instead of your average silica-based minerals like granite.
24:15Imagine stepping on this planet,
24:17and the first thing you notice is that the beaches are made up of black goo.
24:22It's like stepping into a nightmare,
24:24where you're trapped in quicksand made of sticky sludge.
24:29So, forget about the sandy beaches and crystal-clear water you're used to.
24:34Here, you'll be living the pitch life.
24:37Your swimwear will be replaced with hazmat suits,
24:40and you'll need a sturdy pair of boots to walk on the sticky surface.
24:46But, in reality, WASP-12b is not the place to look for geology of any kind.
24:52It's simply too hot for anything to survive, let alone thrive.
24:56But there might be smaller, similar exoplanets where we could potentially live.
25:02Now, you might be thinking,
25:04tar oceans?
25:05That's crazy talk.
25:07But did you know that there's a 246-foot-deep lake of natural asphalt here on Earth?
25:13It's called Pitch Lake,
25:15and it's located in Trinidad.
25:17It's formed when oil is forced to the surface,
25:20and the lighter components evaporate,
25:23leaving the thicker, heavier pitch behind.
25:27And guess what?
25:28This lake is home to a thriving ecosystem of microbes.
25:33So, if you want to live on such a planet,
25:35at least you won't be alone.
25:37You'll have plenty of company in bacteria,
25:40fungi that love to feast on carbon found in asphalt,
25:43and archaea that live on methane.
25:48And finally, there are oceans of molten rock.
25:52That's right.
25:53Imagine a world where the floor is lava isn't just a game, but a reality.
25:59Welcome to 55 Cancri E,
26:01a planet so hot that the entire hemisphere facing its star is covered in magma.
26:07It's like a scene out of a heavy metal album cover.
26:10But don't worry.
26:11The other side of the planet is slightly cooler,
26:14so you can at least step off the lava and catch your breath.
26:19If you're feeling adventurous,
26:21you could always hop over to Koro T-7b,
26:25another super-Earth where the lava ocean is just as scorching.
26:29But this time, the night side doesn't offer much respite either.
26:33It's still seeing constant volcanic eruptions,
26:36like some sort of firework show.
26:40Scientists are scratching their heads trying to explain why these planets are so hot,
26:45and why they haven't cooled down yet.
26:47Maybe they're just really good at retaining heat.
26:50Or maybe they just have a bad temperament.
26:53Either way, it's probably best to stick to playing
26:56the floor is lava on solid ground
26:59and leave the real lava planets to someone else.
27:05All this diversity of oceans
27:07shows us that the universe is always full of surprises.
27:10It never ceases to amaze us with its creativity.
27:13Although these oceans are not suitable for human exploration,
27:17yet, they challenge our understanding
27:20of what could exist beyond our world.
27:22So, let's continue.
