Stories and Realities of space

Welcome to Hell

yep sorry I meant Venus welcome to Venus

some say it's Earth's twin but this

world is nothing like home and you're

about to experience this scorching hot

landscape firsthand

your mission is to spend five seconds on

this hellish planet and trust me these

are going to be a very long five seconds

foreign

and our nearest neighbor at its closest

approach Venus is a mere 40 million

kilometers away from us

after just four months in space you'd

finally be able to witness this

beautiful but deadly Planet up close

four and a half billion years ago Venus

and Earth formed in the same corner of

our solar system

this space rock is about the same size

as earth and its gravity is similar to

but unlike our home the surface

situation on Venus is Extreme

we know this because we've sent probes

to this scorching world

some probes orbited it some made a flyby

and some even landed on the surface of

Venus but those didn't last very long

what happened to them well that's what

you're about to find out

time to make your way down to the

surface

ah don't these clouds look beautiful

well don't inhale them

these yellowish bands streaking across

the sky are clouds of sulfuric acid

if you could only get a whiff of them

you'd smell the reek of rotten eggs

but to do that you'd need to remove your

helmet and I definitely do not recommend

that

at a height of 50 kilometers above the

surface visibility is poor you'd hardly

be able to see anything the incredibly

thick atmosphere would block views of

this planet and its tens of thousands of

volcanoes

the atmosphere is mostly made up of

carbon dioxide and because it's so thick

it traps heat on the planet's surface

keeping it nice and toasty

just how toasty are we talking

oh you're gonna find out the hard way

as you descend another 15 kilometers the

haze would begin to clear

the world below would finally reveal

itself

a rust-colored surface covered in

mountains and volcanoes

looks like this volcano is still active

you'd fly around a little to collect

some samples and take in the view yep

the atmosphere is mostly carbon dioxide

with traces of nitrogen that checks out

okay well let's see if you can land here

this looks like the spot

uh looks like there's no signal

initiating The Landing sequence without

clearance

fingers crossed

Landing your spacecraft would kick up

clouds of dust that would take several

minutes to settle down in the soupy

atmosphere

as it clears you'd look up into the sky

but you wouldn't find the familiar

yellow circle of the Sun

on Venus it always looks like Dawn no

matter what time of day it is

that's because the venusian atmosphere

only lets about 10 percent of the

sunlight that hits it reach the surface

what wait what were we saying earlier

about the space probe that landed on

Venus

oh yeah Venera 13. this Soviet probe

made its fatal Landing back in 1981. it

Survived The Descent and lasted for a

whopping 127 minutes

that's longer than any other spacecraft

that had made it to the surface

but then Venera 13 gave way to the

violent uninviting environment of this

hell it was likely crushed under extreme

pressure or it melted

but it's too late to turn around now

you've lived through the one hour long

landing and you're so close all you need

to do to complete your mission is to

spend five seconds out there

hey yeah out there in the most extreme

environment you've ever been to

foreign

whoa the atmosphere is so strange you

can hardly lift your arms

even though Venus has about the same

gravity as Earth you'd be feeling the

sheer weight of its immensely dense air

it would feel like you were walking

through water

very hot water

and you'd be glad you were wearing so

much protective gear

a quick look at your thermometer would

tell you that it's a sweltering

475 degrees Celsius out here

that's hot enough to melt lead

your pressurized suit would be working

hard to keep you safe without it you'd

be crushed under all that pressure

before you could even complete your

mission

this isn't so bad after all hey if a

spacecraft could last over two hours

some 40 years ago well you and your

shiny new gear can survive longer right

Venus is right here for you to discover

just take a few more steps

suddenly something distracts you from

the first ever first-hand human analysis

of Venus's surface conditions

your protective suit breaks

the DraStic pressure shift would

immediately make you feel like you were

deep underwater

with an atmospheric pressure 90 times

that of Earth Venus would be crushing

you from all directions

at the same time you'd be struggling to

breathe in an atmosphere without any

Oxygen any atmosphere you did manage to

inhale would scald the inside of your

mouth and the top of your throat unless

you could scramble very quickly back to

the safety of your spacecraft you'd be

dead within seconds

hey it could be worse high above you

sulfuric acid clouds would be raining

acid

but in this unbearably hot environment

the toxic rain wouldn't reach the

surface it would evaporate long before

that

so at least you wouldn't have to worry

about acid dissolving your skin and

bones

that would be kind of gruesome

you know in hindsight maybe we shouldn't

have sent you down to explore this

hellish surface we probably should have

terraformed Venus into a more hospitable

Planet first

but that's a story for another

what if

[Music]

[Music]

when you think of ringed planets well

you probably assume there's only one of

them in our solar system Saturn

but what if I told you that there are

three other planets similar to Saturn

yeah it's true Jupiter Uranus and

Neptune all have their own sets of rings

that most people don't know about them

because they're much thinner and pretty

much invisible from Earth

we only learned about them when Voyager

1 and Voyager 2 flew past them in the

1970s and 80s

some scientists even think that Earth

had rings at some point in its existence

four and a half billion years ago when a

planet the size of Mars smashed into our

young rock it ejected so much debris

that it likely briefly formed a small

ring around Earth

despite their unimaginably massive

gravitational pull black holes don't go

around sucking in everything in their

way

it just doesn't work like that black

holes are more like sinkholes

if you were to get too close to one

you'd get spaghettified and lost to the

Blackness of this monstrosity but if

you're far enough away from it you'd be

safe

even if our sun was replaced in the

middle of our solar system by a black

hole with similar mass

all the planets would just orbit like

nothing happened

things would get pretty dark though

now speaking of Darkness the moon

doesn't have a dark side

our planetary partner gets hit by the

sunlight all around

the reason why you don't see the other

side of the moon is because it's always

facing away from us yeah our moon

rotates on its axis at the same rate it

orbits Earth making it what's called

tidally locked to our planet

if a large asteroid is on a deadly

Collision Course with Earth the best

thing to do is to Nuke it

oh sorry wait I've actually got that

wrong

do not nuke asteroids that are about to

collide with us the reason why well

because the nuclear explosion will

shatter the asteroid into millions of

smaller pieces yeah the pieces that

would still be headed for impact with us

instead of dealing with just one giant

asteroid we'd have to deal with multiple

impacts and it would make our evacuation

really difficult or straight up

impossible

now you still can use a nuke to prevent

an asteroid Collision but you don't even

have to strike the space Rock we just

set off a nuke near the asteroid

emphasis on near

then the force from the blast would

nudge it off course that would keep our

planet safe

hopefully

you know nuking the asteroid off course

isn't the only good thing you can do for

our planet sometimes it's simpler than

that like making sure our air and water

are clean unfortunately just the other

week the Supreme Court cut back the

Environmental Protection agency's

authority to regulate water pollution

and that's bad news over the past 50

years the EPA reduced six of the most

common air pollutants by 78 percent and

significantly improved air quality their

work has saved countless ecosystems and

restricting the epa's ability to control

water and air pollution is going to have

serious consequences in the future but

you know what together we can put people

ahead of corporate profits and protect

our environment

speak out vote and make sure your

representatives know how vital the epa's

work is to you we only have one chance

on this planet

standing on Earth at night you can see

thousands of stars but the view from the

Moon is actually quite boring

yeah astronauts who traveled to the Moon

reported that stars aren't easily

visible from there because our moon is

super reflective it really cranks up the

brightness making it harder to see out

to the Stars it's kind of like

stargazing in a city with a lot of light

pollution not fun

you'd need to travel further into space

to get some better views

traveling in space won't make you taller

though it's true that astronauts can

grow up to five centimeters in space

well that's because the Earth's gravity

doesn't weigh them down and the

vertebrae in their spines are able to

expand a bit but this effect is only

temporary as soon as you return to Earth

you get back to your regular height

yeah thanks gravity

and space travel doesn't make you age

slower either not really

Albert Einstein theorized that time

would pass slower for someone traveling

at high speeds versus for someone

stationary this is called time dilation

and while it's true you'd have to travel

incredibly fast to achieve this de-aging

effect like almost speed of light fast

yeah with our current space traveling

technology the difference in time is so

minimal that it's not even worth

calculating

on the off chance that you thought crying in space was

unthinkable well first why and second

you're off-base it's simply unique

without gravity to pull your destroys

they don't stream down your face like

they do here on Earth the tears just

adhere to your eyes and structure a kind of

watery mass

they could try and cover your eyes on the off chance that you

cry a great deal so while you can thoroughly cry

The fact that you makes in space it likely best

don't

not extraordinary for perceivability

hello Martian residue storms are a genuine

cerebral pain the residue particles are so fine

that they can go anyplace and these

dust tempests can keep going for quite a long time however they

can't actually harm any gear

that we leave on the red planet

the thing is that the Martian

climate is really dainty pretty much one

percent of the climate we have on

Earth so in any event, when these residue particles

Fly around at around 100 kilometers for every

hour

they can't sneak up suddenly without the

help of air

in any case, what they can do is cover our sun based

boards and placed our Wanderers into power

saving hibernation

goodness and I wouldn't breathe in this residue

either who understands what this fine powder

could do to your lungs long haul

sparkle little star how I wonder

what you are up over the world so high

this tune is a gigantic untruth

definitely regardless of the well known youngsters' tune

Stars don't sparkle the flashing is

Simply a Deception their light is in fact

extremely consistent

stars seem to sparkle because of the gas

atoms that make up our climate

they divert a portion of the light from

Stars causing them to show up as though they're

shining

space rock belts are regularly portrayed as

minefields of drifting rocks spaceships

need to zigzag all around the

space rocks in a critical circumstance

in any case, as a general rule our space rock belts are

not at all like what you find in the motion pictures

space rocks aren't unreasonably near one another in

reality they're very far separated

for instance in the space rock belt between

Jupiter and Mars every one of the space rocks

is a few million kilometers from

their closest neighbor

furthermore, the possibilities of a crash are about

one of every one billion

so while Khan Chewie and Leia had you on

the edge of your seat and The Domain

Strikes Back space rock Fields like that

are a long way from the real world

the Incomparable Mass of China is known to be

the main man-made object that is noticeable

from space

however, this is totally bogus

better believe it sure perhaps you could see it with a

camera and a long range focal point yet it's nearly

imperceptible to the unaided eye

add 5 to 10 meters wide the wall is way

excessively slight to be seen from space anyway

you can in any case see a lot of other

man-made objects from space things like

dams Scaffolds and pyramids and around evening time

you can see a light show from the

world's huge urban communities
