sound may not be able to travel in space
but the universe is always talking to us
every moon every planet every system has
its own sounds and language
and as we continue to explore space
we're introduced to more and more of
them
but not all of these noises are pleasant
and welcoming
welcome to fact nominal and today let's
review the strangest recordings nasa has
ever captured in space
[Music]
human ears are specially designed to
translate changing pressures traveling
through a medium that is sound waves
without the medium these sound waves are
rendered mute and as space as a vacuum
sound waves cannot be heard through it
but many other waves can still traverse
through a vacuum such as radio waves
thanks to such vacuum-friendly waves
like radio we can still translate sounds
that the universe is throwing at us in
the last two decades we have reached the
far corners of our solar system with
unmanned devices and a couple of these
devices have now breached that boundary
and are now listening to the
interstellar voices
but are we meant to listen to these
sounds
for example let's start with our
neighbor you all know mars right
the shy little red planet that lives in
the next orbit from our earths the one
we have been eyeing for a long time as
our next home
mars wasn't as lucky as the earth when
the sun was choosing a planet to be in
the goldilocks zone and as a result
narrowly missed it losing its weak
environment completely
in current times the interior of mars is
fairly quieter than earth but still that
doesn't mean it's entirely serene quakes
happen underneath the surface of mars
all the time
nasa sent the inside lander in 2018 to
give the red planet its first thorough
checkup since its birth four and a half
billion years ago
with it a seismometer so it could record
seismic activity data and in april of
2019 the little fella got its first hit
[Music]
the sound you are hearing in this video
was captured on april 6 2019
the sounds were created from the ground
vibrations as insight detected three
distinct events
martian wind a marsquake and the
spacecraft's own robotic arm as it moved
to take the picture
listening to this sound reminds us of
the creepy sound monoliths made in
stanley kubrick's epic 2001 a space
odyssey they still give me the creeps to
this day
before we unveil this sound there is a
disclaimer the sound you are about to
hear is not only unpleasant but it is
also an audio version of a graph of the
voyager's plasma wave science
observations of several months spanning
2012-2013
these readings mark the period at which
scientists believe voyager exited our
solar system's heliopause making it the
very first sound we captured from
outside our solar system even if it was
in the form of data
[Music]
however it isn't as beautiful or
thrilling as one might expect but rather
quite shrill and horrifying
could this be a sign that we were never
meant to leave our home
saturn is named after the god of the sea
in roman mythology
long before voyager crossed the solar
system's threshold to explore the vast
universe all by itself it did us a huge
favor by studying every cosmic object
inside our solar system that it could
reach on its way out thus giving us
information that we never had before
voyager was the first one to indicate
the presence of lightning deep within
saturn but it was cassini that gave us
definitive proof that the name of the
tempest god was quite fitting for the
big blue giant of our solar system
in 2006 cassini captured staticky
crackles in radio waves and showed the
chaotic environment simmering deep below
saturn's cloud top
these noises are truly a god's wrath
incarnate
another incredible recording captured by
cassini's flyby was what crossing
saturn's rings actually sounds like
10 years after capturing saturn's
thunderstorm cassini gave us the
thrilling experience of what it would be
like to fly inside the perilous rings of
saturn
the static you are hearing was recorded
by cassini's radio and plasma wave
science instrument as it crossed the
plane of saturn's rings in december of
2016.
this is the closest we'll ever get to
imagining what kessel run must have been
like for han solo
[Music]
jupiter is the big brother of our solar
system it protects small planets in the
inner orbits including our earth from a
lot of threatening comets and other
interstellar dangers keeping the system
in balance and is aptly named after the
king of the ancient roman gods jupiter
it is also a gas giant which nearly
missed its opportunity to become the
second star of our solar system a brown
dwarf to be precise
with so many interesting things going on
with this planet naturally our curiosity
never dies
thanks to cassini in january 2001 we got
to hear what a god sounds like during
its historic 20-year mission to saturn
cassini had to take a pit stop near
jupiter to receive a crucial
gravitational boost to successfully
complete its journey
during this time cassini captured these
spooky and quite alien sounding radio
signals from jupiter
no wonder there's always a storm brewing
at the house of the thunder god of
ancient rome
however this raging and thrilling sound
wasn't the first time we heard jupiter
while the voyager was passing by jupiter
it was fortunate enough to capture
jupiter's retort to the sun called the
bosha
if you don't know what that is here's a
simple explanation the sun emits a
steady stream of charged solar wind
which can be repelled by a strong
magnetic force such as the magnetic
field of a large planet
when the solar wind meets the strong
magnetic force surrounding a planet it
is deflected and all its energy of
motion is converted to thermal energy
this energized region is known as a bow
shock
it definitely sounds like the planet is
blowing off some steam like a highly
pressurized cooker
this audio is highly unnerving and could
remind you of some of the most stressful
horror scenes in movies the latest word
that we have heard from jupiter has
quite a pleasant name called the groovy
track however don't be fooled by the
name nasa collected it in february 2017
with the juno spacecraft named after the
ancient roman goddess and wife of
jupiter
the audio gathered by juno is the sound
of plasma waves in jupiter's ionosphere
this one yet again would remind you of
the precursor technology of the fourth
dimension beings that were suggested to
be behind humans evolution in 2001 a
space odyssey
given that the wormhole's location in
the movie was very close to jupiter it
sure is an eerie coincidence
[Music]
in 1989 the galileo space probe was
launched to study jupiter and its moons
as well as the asteroids gaspara and ida
in addition to sensors to monitor the
particles and fields of the solar wind
throughout the interplanetary cruise and
then within jupiter's magnetosphere
galileo was equipped with a scanned
platform that carried four optical
instruments
a high-resolution camera was
complemented by a near-infrared mapping
spectrometer an ultraviolet spectrometer
an integrated photopolarimeter and a
radiometer
during two passes into the asteroid belt
galileo flew past the asteroids gaspar
in 1991 and ida in 1993
thereby providing the first close-up
views of such bodies
it also discovered a tiny satellite
orbiting ida which was named dactyl
galileo also furnished a unique
perspective of the collision of comet
shoemaker levy 9 with jupiter as it
closed in on the planet in july of 1994.
over the next five years galileo flew a
series of orbits that produced close
encounters with jupiter's fourth largest
moons io europa ganymede and callisto
while studying galilean moons scientists
discovered some very strange plasma wave
observations which later turned out to
be the evidence of these moons having
their own magnetosphere
a magnetosphere is the region of space
surrounding a cosmic body where the
dominant magnetic field is the magnetic
field of that particular body instead of
anything else and or the magnetic field
of interplanetary space
moreover this discovery unveiled the
constant magnetic war these moons are
having with their host planet jupiter
the violent sounds that you are about to
hear come from the magnetosphere of
ganymede europa and callisto with
callisto having the weakest
magnetosphere of the four major moons of
jupiter
not only are these sounds deeply
disturbing but also extremely violent
and menacing
the sun is the powerhouse of the entire
solar system
everything moves feeds and powers its
actions directly or indirectly through
the energy provided by it
any power producing device on earth
tends to produce a humming sound
to create energy a device itself
consumes energy and channels it by
converting it from one form to another
as the material of the device moves
waves travel and as waves travel through
a medium they create sound
nasa collected the waves traveling and
bouncing inside the sun and converted
that jiggle into sound so we can hear
what goes down inside the cosmic
powerhouse of a star
and eerily the low frequency version of
it isn't much different from a generator
or any other power producing machine
moreover this humming can easily crawl
under your skin and make you feel uneasy
in no time
so tell us in the comments which sound
made you the most uncomfortable
also what other cosmic subjects would
you like us to cover next
but for now thanks for watching fact
nominal we'll see you next time
