We're About to Witness a Once in a Lifetime Space Explosion Visible From Everywhere

so even though the biggest astronomical

event of 2024 is I guess the solar

eclipse on April 8th of 2024 at least

that's the one that everyone is talking

about technically for astronomers it's

not that ear it's actually the event

we're going to be discussing today and

it's a recurring event that happens

every 80 years and so basically in 2024

we get two separate opportunities to

observe something that we usually don't

get to see obviously the solar eclipse

but also what's known as a recurrent

Nova and so how wonderful person this is

Anton today we're going to discuss this

astronomical event that actually might

have already happened when you're

watching this video or it might have not

we don't actually know the exact date

yet but it's happening really really

soon or so thees scientist think but

first let's actually talk about what it

is and how all of this works and it all

starts with wide Wars these very unusual

objects we're going to be discussing

again in a video very soon because

something really important was

discovered about them but also a type of

an object that the sun is going to

become as well this is what's known as a

stellar Remnant in some sense the core

of the star itself that becomes

extremely dense and collapses on itself

but is unable to produce a neutron star

or a black hole because it just doesn't

have enough Mass but it does have enough

Mass to form what's known as electron

degenerate matter on the inside that's

able to prevent further collapse in

other words it's actually been compared

to a kind of an ocean of electrons that

because of various Quantum effects such

as the inability of electrons to be in

the same place prevents the object from

growing smaller and maintains the

overall size and shape and most of the

stars in the galaxy including our sun

are going to become one of these and

they're actually going to stay this way

for billions and billions of years wide

Wars tend to stay this way and don't

change much over a very long period of

time but the thing is about half of the

stars in the galaxy are binary and that

means that sometimes you'll actually get

two stars growing older at different

times one might have already become a

whitew Warf and one is still in its red

giant stage and if these two stars orbit

close enough they actually tend to

interact producing very specific very

unique effects one might have already

become a whitew Warf but the other one

is still going through its red giant

stage and so here as the red giant

starts to expand and starts to basically

become larger and larger sometimes it's

our layers start to interact with the

wide dwarf and in those cases wide

dwarfs will actually start absorbing a

lot of this mass and essentially create

an accretion disc around themselves

forming something similar to what you

see right here and in those cases when

these accretion discs become thick

enough or actually acquire just enough

Mass they reach a kind of instability

period where at some point within just

weeks or sometimes months they reach a

point of a nuclear detonation literally

a massive nuclear bomb explodes around

the wiw warf as most of the acction disc

suddenly turns into energy and in

essence this is what we call Nova not

super nova just Nova it's cool that

because back in the days from a distance

it looked like some kind of a new star

and Nova means new and this is basically

what we're going to be observing

sometimes in 2024 but the thing is I've

actually discussed this particular

prediction almost like a decade ago I

think possibly in 2016 this is when

originally some initial predictions

started to be made and so back then

researchers actually realized something

unusual about a system known as T Corona

Borealis A system that we already knew

was actually a Nova previously possibly

at least twice the most well-known

eruption was back in 1946 and it was

obviously studied and observed by a lot

of different astronomers but originally

this particular star was found back in

1866 80 years prior because of its

previous eruption and because normally

you're not actually going to be able to

see the star without at least binoculars

or a small telescope but in 1866 and

1946 suddenly we had a new star we had a

Nova with this lasting for just under

one week and this was a pretty bright

star it suddenly became one of the 100

brightest stars in the night skies

Technically when it happens again it's

even going to be visible in a typical

City here white pollution is not going

to hide it and so several studies from

years ago essentially analyzed the

active state in 2015 and 2016 realizing

something really strange here the star

suddenly became a little bit brighter a

little bit more active produced more

radio light produced more x-rays with

the overall increase in production

extremely similar to what happened in

1938 basically 8 years before the 1946

eruption moreover additional

observations and additional studies from

just a few years ago revealed an unusual

dip or unusual demmon event sometime in

June of 2018 and then a much larger dip

in March of 2023 basically last year and

this was extremely similar to a very

sudden dip in 1945 as you can see here

it was May to June 1945 and literally 9

to 10 months later we suddenly had this

very large very explosive event as a

result that particular paper predicted

that this Nova will probably happen in

January of

2024 well it didn't but I think it's

more it didn't yet in the past a lot of

predictions of various Nova usually

involved large timeline errors and so in

this case it's probably going to be at

least plus minus 7 months now because

this particular star is approximately

3,000 light years away from us being

able to suddenly see it with a naked eye

is already pretty impressive but what's

even more impressive is actually if you

compare this to other Nova and

specifically are the recurrent Nova

here's a very short list there's

basically like a dozen or so and most of

them are really well known and moreover

pretty much for most of them the

predictions so far have been relatively

accurate the most recent one was just

over a year ago and it was a recurring

Nova in U scorp here the peak magnitude

was approximately eight then just a year

prior to this we had an eruption from a

very famous Nova RS of fokai and this

one is known to have happened many many

times but here the brightest it's ever

been was magnitude of five sore visible

with a naked eye but kind of difficult

this though the Nova that's about to

happen is going to be 2.5 magnitude and

if you know anything about magnitudes

that's pretty bright it's extremely

close to the famous North Star or

Polaris meaning that it's going to be

extremely easily visible not as easily

visible as serus which is a little bit

brighter and actually does contain its

own wiw Warf right there but definitely

bright enough to be visible from a

typical City and moreover once again

this is one of those once in a lifetime

events it seems to happen every 80 years

and intriguingly one of the scientists

wanted to find out if the period is

really 80 years or not and so Bradley

Sheffer essentially went through various

historical records looking for signs of

unusual stars in this region and he did

find writings from Reverend Francis

Williston who back in 1789 reported an

unusual star appearing for a few days in

the location of Corona Borealis pretty

much exactly where we expect this NOA to

happen likewise sixth Century before

this in 12177 there was an eyewitness

report by Abbott Berard of absur of some

kind of a stellar source that suddenly

produced a lot of light and lasted for

many days back then he saw this as a

wonderful sign today we also see it as a

wonderful sign but for a very different

wonderful reason scientific reason it

basically reminds us that modern science

is super correct and helps us predict

events we knew nothing about just a few

hundred years ago and so I guess the

question is okay so when exactly is it

going to happen since we only have a few

days to observe it how do we make sure

we don't miss it well right now the

prediction is set for April plusus 3

months so basically April May June July

maybe August maybe September and so by

September of 2024 we should see

something the Nova should have already

happened because right now the

observations are very similar to various

PR NOA events in 1946 and just to make

this a little bit more interesting let's

turn it into a game try to predict it

leave a comment below with some kind of

a date essentially starting today up

until I guess anytime in the future when

you think this might happen and if one

of you wonderful prophets succeeds in

guessing the actual day of the Nova oh

there might be a surprise or present or

something I didn't really plan this one

yet but I don't know you might get

something possibly a t-shirt possibly

something else I'll think about it but

anyway I'm going to start I'm going to

go with a date that's kind of important

for me personally September 27th I'll

explain why a bit later so yeah as long

as you predict this before it happens

not on a day and not after I'll consider

you a winner and if a bunch of you

predict the same date I guess you're all

winners kind of anyway either way when

this happens it's going to be very

important for the scientific Community

being able to observe these events in

real time and studying what happens to

these Stars the red giant and the whitew

warf which are the same two stages our

son is going to go through as well we'll

probably teach us a little bit more

about what happens to these St and what

might happen to the Sun as well and in

case of this particular system it

already has a few mysteries for example

for some reason there seems to be an

unusual lack of oxygen inside the red

giant currently it's unknown why on top

of this the scientists want to

understand why there are so few of these

recurrent Nova out there now previous

research suggested that all Nova are

recurrent they just have very different

periods some of them happen every few

years some of them might happen every

few centuries so we basically don't live

long enough to see any of them

nevertheless because there are only like

a dozen so far known to us in the Galaxy

that by itself is a really small number

and that of course highlights how

exceptionally rare this particular event

is way more rare than the solar eclipse

and way more rare than anything else

we'll see in the next few decades okay

except for maybe Certain comets but most

comets are pretty common and so

basically in the next few months we'll

be hearing more about this binary system

3,000 light years away from us with two

tus orbiting each other every 228 days

in case you're wondering the distance

between them is approximately half as

much as the distance of Earth from the

Sun but because the transfer of material

is about to reach its peak which is

probably why we're seeing these unusual

dips it means that the exposion itself

is pretty much imminent it's definitely

going to happen any time now and the

reason I'm saying this with so much

confidence is because previous

predictions from for example us Scorpio

were also spot on as well this was

predicted years ahead had and it

happened within just a few months of the

predicted date same thing for this

particular Nova and for many others but

because this is going to be the

brightest event ever possibly the

brightest one we're going to see for at

least another Century that's why it

deserves its own video in terms of

science and astronomy this is going to

be much much bigger than the solar

eclipse and so once it does happen we'll

come back and talk more about actual

discoveries and if one of you guesses

the date we'll probably talk about the

winner and the prize until then thank
