Space is incredibly vast and seemingly infinite, full of wormholes, black holes, and undiscovered
planets. We’ve discovered so little of space that it is almost terrifying, considering
we are but a tiny speck of dust in the universe. If we, humans, are so small and make very
little impact on the universe as a whole, how could we possibly be alone in the world?
Is it really just us? Well, according to some signals, no. Today on Top 5 Scary Videos,
I’m going to be counting down our list of the Top 5 Scary Signals From Outer Space.
Let’s jump.
5 SHGb02+14a Yep, that’s a mouthful.. This is an astronomical
radio source and a candidate in the search for Extra-Terrestrial Intelligence, discovered
in March 2003 by SETI@home. Now, the source was observed three times for a total of about
a minute at a frequency of about 1420 MHz, one of the frequencies in the waterhole region,
which is theorized to be a good candidate for frequencies user be extraterrestrial life
to broadcast contact signals. Now, the region it hailed from is usually devoid of any nearby
stars. The closest star systems in the approximate region of the signal include the binary star
G73-11A and B, which are 106.1 light-years from the Sun, although the unrelated star
G73-10 is only 108.7 light-years away, less than three light-years from G73-11A and B.
All of these stars are Red Dwarfs, which is the smallest and coolest kind of star on the
main sequence, and are by far the most common type in the Milky Way. Now, there are a number
of puzzling features of this candidate, which have led to a large amount of skepticism.
The source itself is located between the constellations Pisces and Aries, a direction in which no
stars are observed within 1000 light years from Earth. It is also a very weak signal.
The frequency of the signal has a rapid drift, changing by between 8 and 37 hertz per second.
Now, here’s where things get interesting. If the cause is Doppler Shift, it would indicate
emission from a planet rotating nearly 40 times faster on its axis than the Earth. Each
time the signal was detected, it was again at about 1420MHZ, the original frequency before
any drift. Of course there are many explanations for the signal, however, many are purporting
an artifact of random chance, cosmic noise or even a glitch. I’m here for Aliens though.
4 FRBs One of the biggest mysteries out there in
the universe is of course, “is there something other than just us, or are we alone in the
universe? Well, as of August 14th, 2019, we have inched closer to an answer. An astonishing
eight new repeating audio radio signals known as Fast Radio Bursts, aka FRBs, have been
detected flaring from deep space. Creepy. At the beginning of 2019, just one of these
signals was reported to flash repeatedly, however, in January, scientists reported a
second repeating one. This means we’re beginning to build a statistical database of repeaters,
which would help astronomers figure out what these signals actually mean. These FRBs are
perflexing, and are detected as spikes in radio data, lasting just a few milliseconds,
but in that time, they can discharge more energy than 500 million Suns. I quote: “Just
as some volcanoes are more active than others, and you can think a volcano is dormant because
it has not erupted in a long time.” this can be said about FRBs. There is also a frequency
drift, the first two repeaters showed a downward drift in frequency, which each burst getting
successively lower. Kind of like a sad trombone sound effect. As of right now, Scientists
are attempting to figure out where the FRBs are hailing from, and what exactly the signals
mean. Perhaps it’s from extra-terrestrial life, telling us they’re out there. Or perhaps
it’s something far more sinister.
3 Tabby’s Star Also known as KIC8462852, Boyajian’s Star,
or WTF Star, is an F-Type main-sequence star located in the constellation Cygnus approximately
1,470 light-years from Earth. Unusual light fluctuations of the star, including up to
a 22% dimming in brightness, were discovered by citizen scientists as part of the Planet
Hunters project. In September 2015, astronomers and citizen scientists associated with the
project posted a preprint of an article describing the data and possible interpretations. The
discovery was made from data collected by the Kepler Space Telescope, which observed
changes in the brightness of distant stars to detect exoplanets. Now, Tabby’s Star
is not the only star that has large irregular dimmings, but all other such stars are young
stellar objects called YSO dippers, which have different dimming patterns. Now, several
hypotheses have been proposed to explain the star’s irregular changes in brightness as
measured by its light curve, but none to date fully explain all aspects of the curve. One
explanation is that an “uneven ring of dust orbits Tabby’s Star. Another explanation
is that the star’s luminosity is modulated by changes in the efficiency of heat transport
to its photosphere,s o no external obscuration is required. Now, a third hypothesis, based
on a lack of observed infrared light, posits a swarm of cold, dusty comet fragments in
a highly eccentric orbit, however, the notion that disturbed comets from such a cloud could
exist in high enough numbers to obscure 22% of the star’s observed luminosity has been
doubted. It has also been hypothesized that the changes in brightness could be signs of
activity associated with intelligent extraterrestrial life constructing a Dyson swarm; however,
further analysis based on data through the end of 2017 showed wavelength-dependent dimming
consistent with dust not not an opaque object such as an alien megastructure.
2 WOW! Signal The Wow Signal was a strong narrowband radio
signal received on August 15, 1977, but Ohio State University’s Big Ear radio telescope
in the United States, then used to support the search for extraterrestrial intelligence.
The signal appeared to come from the direction of the constellation Sagittarius and bore
the expected hallmarks of extraterrestrial origin. It was Jerry R. Ehman, an Astronomer,
who discovered the anomaly a few days later while reviewing the recorded data. He was
so impressed by the result that he circled the reading on the computer printout, and
wrote the comment WOW on its side, leading to the event’s widely used name. The signal
itself lasted for the full 72-second window during which Big Ear was able to observe it,
but has not been detected since, despite several subsequent attempts by Ehman and others. Many
people have made assumptions about the source of the sound, including natural and human-made
sources, but none of them adequately explains the signal. To this day, the WOW Signal remains
the strongest candidate for an alien radio transmission ever detected.
1 The Judica-Cordiglia Brothers The Judica-Cordiglia Brothers are two Italian
former amateur radio operators who made audio recordings that allegedly support the conspiracy
theory that the Soviet Space Program covered up cosmonaut deaths in the 1960s. The brothers
claimed to have acquired recordings of several secret Soviet space missions that ended in
tragedy and mystery. This has of course generated public interest for man than 50 years, despite
there being a large number of detailed rebuttals to the brothers’ claims. In the 1960s, the
brothers claimed to have heard radio communications taken from the secret space missions, including
the dying sounds of a suffocating “lost cosmonaut”. One of their most famous recordings
was made on November 28, 1960. After about an hour of listening to static, the bothers
recognised an SOS signal that seemed to be moving away from the Earth. In 1963, the brothers
claimed they recorded the voice of a demal cosmonaut reentering the Earth’s atmosphere
in a malfunctioning spacecraft; in the recording she is heard to have cried out “I am hot”
as it burnt up. In total, the Judica-Cordiglia Brothers released nine recordings over a period
of four years, the details were as follows: * May 1960, a crewed spacecraft reports it
is going off course. * November 28, 1960, a faint SOS Morse Code
signal is sent from another troubled spacecraft leaving Earth's orbit.
* February 1961, a cosmonaut is audibly recorded suffocating to death.
* April 1961, a capsule is recorded orbiting the Earth three times before re-entering the
Earth’s atmosphere just days before Yuri Gagarin made his historic flight.
* May 1961, an orbiting spacecraft makes an appeal for help after going out of control.
* October 1961, a cosmonaut loses control of his spacecraft which veers off into deep
space. * November 1962, a space capsule misjudges
re-entry bouncing off the Earth’s atmosphere and out into space.
* November 1963, a female cosmonaut dies during re-entry.
* April 1964, another cosmonaut is killed when his capsule burns up in the Earth's atmosphere.
Since the 60s critical analysis of the recordings has cast doubt on their provenance. For instance,
audio transcripts reveal that none of the cosmonauts, were supposed to be Soviet air
force pilots, followed standard communication protocols, such as identifying themselves
when speaking or using correct technical terminology. Fishy, fishy. Still, I have doubts, I think
something greater is going on here.
