just before we get started with this video if you like science and space theme videos be sure
to check out eric malakai's new channel science get eric actually wrote the script for today's
video and on his channel he talks about all sorts of sciency stuff it's informative and fun there's
a link below as the late great author douglas adams once wrote space is big you just won't
believe how vastly huge mind-bogglingly big it is i mean you may think it's a long way
down the road to the chemists but that's just peanuts to space and as such there are a lot
of unexplained phenomena out there including fast radio bursts and a host of other signals that have
come from the depths of space these deep space signals have the curious property of
causing us bipedal ape descendants down here on earth to collectively scream aliens whenever
such phenomenon are announced but while most of them remain unexplained the majority of
these signals are most definitely not coming from aliens at least that's what we currently
think in the video today 10 strange signals from space that we still don't understand
10. sgr 1935 plus 2154 since 2007 fast radio bursts or frbs have puzzled astronomers frbs
are extremely powerful flashes of radio waves that are typically detected in galaxies millions
if not billions of light years away from us and in 2020 astronomers tracked one of these bursts
to a magnetar in our own galaxy magnetars are neutron stars with a magnetic field measuring
about a thousand times more powerful than the earth's these magnetic fields are so
powerful that they tend to wreak absolute havoc on anything that orbits them to put it another way if
a human were to get too close to a magnetar let's say about a thousand kilometers or so
the bioelectric processes of the body would be interrupted and the molecules
making up the body would scatter basically this hypothetical person would dissolve faster than
a post-snap spider-man so magnetars are pretty powerful and terrifying and scientists have
suspected that they're the cause of these fast radio bursts sgr 1935 plus 2154 is the
first instance where an frb had been tracked to its source this particular burst is interesting
because it's the most powerful frb that we've recorded so far with an energy
three times as strong as the emissions coming from our own sun but just because we've tracked
the frb to its source doesn't mean all fast radio bursts come from magnetars as magnetos
are extremely rare in our own galaxy there are about 30 candidates in total and like magnetars
we don't really understand what causes fast radio bursts in the first place 9. frb180916.js
plus 65. this particular fast radio burst lasted about four days arriving at seemingly
random intervals followed by 12 days of total silence then four days of chaotic bursts and
rinse and repeat while some frbs have been tracked to magnetars that's not the case for all of them
in the case of this one yes i'm not really going to read that name again the repeating signal was
coming from a galaxy 500 million light years away but the source is still unknown while
it is a possibility that this frb comes from some type of magnetar that's not something that
astronomers can say for sure scientific method at all the prevailing theory about 1.0916 is
that it's coming from a lone neutron star with an odd wobble that has caused the supernova remnant
to become deformed more data and studies will be needed in order to narrow the possibility down low
the galaxy in question however is extremely active with new stars being born at a rate
of 100 times faster than we have here in the milky way number 8. the wow signal
the wow signal was first detected in 1977 by ohio state university's big ear radio telescope in the
united states the radio telescope has long since been decommissioned and replaced by a golf course
far from its history-making glory days the wow signal was a powerful narrow band signal that
lasted for 72 seconds standing out against the background noise like a lighthouse in the dark
the source of it remained a total mystery for 40 years with a prevailing theory emerging in
2017 that the source was actually from a comet a hypothesis that's been heavily scrutinized
as of late unlike some of the radio signals in this video however the wow signal is the only
one that stands out as potentially from an alien civilization when it was observed by jerry irman
the man who analyzed the date printout he famously wrote wow next to its boring designation of 6eq
uj5 while urban waited on the edge of his seat for the signal to hopefully return
he never did but thanks to the european space agency's gaia telescope we may finally have an
answer sort of gaia has mapped over 1.3 billion stars and using its data an amateur astronomer
had the bright idea to search for sun-like stars in the region of the sky where the signal was
originally detected finding a total of 67 stars loosely fitting these criteria and one among them
was an exact match now the search is on for exoplanets in this area though ironically the
signal source is still a mystery at least for now 7. the lorimer burst what is known as the lorimer
burst was the first frb ever discovered the radio burst was detected by park's multibeam receiver
after it saturated its primary detection beam this implied that the location of the burst was between
the beams requiring an extremely high peak flux density this frb is still considered to be one of
the brightest as it exhibits higher fluence than most of the fast radio bursts that been detected
since its discovery one explanation for this frb is that it's actually the emission of gamma
rays coming off of a pulsar from the direction of the large and small magellanic clouds though the
source is still unknown 6. the woman who fell from the sky two italian amateur radio operators
known as the judica chordiglia brothers claimed in 1961 to have made a startling discovery with
their radio equipment which was set up just outside of turin an abandoned german bunker
they allegedly picked up a transmission coming from somewhere between north america and russia
of a woman pleading for her life the recording has featured a panic russian woman's voice complaining
about extreme heat while she runs out of breath the woman's voice becomes increasingly more
distressed before the recording finally ends presumably with the first female cosmonaut's
death the idea that russia has covered up the deaths of their cosmonauts in space is
not really a new conspiracy theory but it's one that has a few blips of evidence to back it up
even if the modern day russian space agency continues to deny that these events happened
though it is intriguing that three days after this radio transmission was detected and recorded
on may 26 1961 it was announced by tass the soviet press agency that a large unmanned satellite had
burned up upon re-entering the earth's atmosphere number 5. the blinking stars
when laval university astronomers ef borough and e trottier submitted a study about a
mysterious group of 234 stars producing a strange blinking pulse of light with regular occurrence
the collective internet cried out but certainly this must be a signal for aliens borah claims
that the patterns seen from the stars are eerily close to patency predicted would be
found in messages sent by an extraterrestrial intelligence in a 2012 paper but to paraphrase
neil degrasse tyson in every occurrence where a mysterious signal from space has been detected
those phenomena are always explained naturally but borah and trottier are singing a different tune
they argued that such a signal could be explained by a civilization that is attempting to talk to us
and even offer arguments against at least three natural explanations for the phenomena while this
is of course an extraordinary claim and while we do not know what sort of phenomena could be
causing these stars to appear as they do a natural cause cannot be ruled out explanations for the
mysterious phenomena have raged from human error to galactic halo stars with strange compositions
4. signals from a black hole there is no sound in space not really but plasma vibrations radio
waves electromagnetic disruptions and charged particles interacting with the various things in
the depths of space can be translated into sound waves for our ears voyager 1 famously recorded
the sounds of all the giant planets in the solar system emissions detected from what is suspected
to be a supermassive black hole in the perseus galaxy cluster 300 million light years from us
have been singing the same note for 2.5 billion years registering once translated 57 octaves
below middle c while the signal itself remains mysterious scientists suspect that the recordings
are caused by matter escaping the accretion disk around the black hole you might ask but i
thought nothing could escape from a black hole's gravity well and you'd be mostly correct but we
do see intense emissions coming from the poles of supermassive black holes called relativistic jets
which can shoot gas and supercharged particles across millions and millions of light years of
distance number three galactic kraken in 2006 nasa was in for a shock when they launched a balloon 36
576 meters into the atmosphere that was supposed to detect signals from
the first stars ever born the signal they ended up detecting when translated into an audio wave
was six times louder than anything that had been detected up until then scientists at nasa however
do not think this signal was coming from the first stars but rather something else that is keeping
them from detecting them as of now this radio emission still hasn't been explained to put this
emission into perspective consider that when the milky way's emissions are translated into sound
they come off as a dull static hiss and other galaxies are similar in this regard even now this
emission is still six times more powerful than any radio signal recorded since and there isn't
mention in any of the materials of fast radio bursts surrounding the space raw as nasa decided
to call it number two shgb02 plus 14a scientists working at seti moved quickly to dispel rumors on
the internet that a home monitoring station had detected a signal from an extraterrestrial source
the culprit shgb02 plus 14a seems to be located between the constellations of pisces and aries
at a distance of about a thousand light-years from earth the problem there are no known stars in the
region where the signal came from seti however suggests that this signal is not even on their
radar and that it's not a contender for further investigation natural explanations include cosmic
background noise random chance and potential technical error though none of these have
been identified for certain as the cause of the emission 1. hd-164595 it takes a lot to get seti
interested in something they pick up hundreds of radio signals in space and most of them end
up not amounting to much but the emissions that they detected from star hd 164595 are a bit of
a different story the star in question rests about 91 light years from earth and while older than our
sun it's remarkably similar it is also known to have a planet orbiting it the first signal
was detected on may 15 2015 and it weighs in at an amplitude of 750 million hertz researchers suggest
that if this signal came from an isotropic beacon then it would have come from a type 2 civilization
on the kardashev scale but if the signal is a beam aimed directly at our solar system then it would
most likely have come from a type 1 civilization to put this in perspective bar civilization is
thought to be somewhere between type 0 and type 1 with type 1 being a planetary civilization capable
of harnessing the power of their own world and type 2 being a civilization capable of harnessing
the power of their entire solar system but before you get excited just because scientists are
throwing out these terms does not mean that the signal was definitely sourced from aliens but
intriguingly the rat and 600 researchers called to keep seti's radio telescopes tuned in the
direction of hd164595 permanently so i really hope you found that video interesting if you did please
