NASA DISCOVERS NEW GALAXIES
Is this the discovery of how it all started ?
During the recent years scientists made
two breakthrough discoveries about our
universe thanks to new technologies.
We’ve looked into the distant past
and we've learned something that can
change our understanding of the universe
forever.
What are these discoveries and what do
they mean to us, let's find out,
recently, we unveiled the first color
image from the James Webb Space
Telescope. It’s a mind-bending photo
capturing thousands of ancient galaxies.
This oldest documented light in the
history of the universe dates back over
13 billion years, that's just 600 million
years after the Big Bang .It’s like
getting a sneak peek into the universe's
baby album,
but that was just the beginning.
Astronomers were expecting to see some
tiny young galaxies, but what they found
was a real surprise impossibly early
impossibly massive and all that from
just a tiny red dot.
The lead author of the study ,Evo laba
was working at the computer as usual, and
suddenly he got two numbers age 13
billion years weight 100 billion stars,
when he realized what that meant he
nearly spit out his coffee,
but that red dot was just the beginning.
The next day they found five more
galaxies just like this, turns out these
six massive galaxies are as old as The
Milky Way itself.
The entire research team was in
disbelief they were like, wait what these
guys couldn't be that mature so early in
time did we make a mistake, but nope the
James Webb Space Telescope the new cool
guy on the space block just has some
serious skills. It can see through dust
clouds with its infrared vision and spot
galaxies that were previously invisible.
Move over Hubble there's a new Stargazer
in town,
but why is it shaken things up so much,
because this discovery affects our
understanding of how galaxies formed.
Let’s try to explain a long time ago,
13.8 billion years ago to be precise,our
universe was born. It was chilling out
for a while and then it started to form
the first galaxies, and these galaxies
were full of gas and dust eventually
this gas started turning into Stars. Some
galaxies were more massive and had more
stars, and some were lighter and had
almost no stars at all.In any case they
all grew, gradually the stars in them
were born slowly and smoothly,
that's how our current models explain
this,
but these new observations from the
James Webb Space Telescope show an
unexpected surprise.
Looks like even in the early Universe
our ancient friends had lots of stars,
more than what we would ever expect.
If that's the case, then these galaxies
are like the overachievers of the
universe, they skip the small and gradual
growth phase and went straight to being
giant Universe Breakers. According to our
current cosmological model, they
shouldn't even exist,
but they do so it looks like after the
Big Bang, the stars were forming much
faster than we thought, which is pretty
weird.
This could mean that there's something
missing in our understanding of the
Galaxy formation.
As you can see these Universe Breakers
are really living up to their name,
causing a potential total consensus
among scientists.
The universe was like” Hey I'm about to
flip cosmology models upside down”,
but let's not jump to conclusions,there
are many theories that could explain
these mind-boggling discoveries ,without
breaking the standard model.
For example ,maybe the light we're seeing
isn't coming from stars at all,but from
the swirling discs of Doom around
supermassive black holes.
These colossal Cosmic beasts can gobble
up matter and spit out a dazzling light
show, and James Webb telescope's Keen Eye
is picking up on these enigmatic
accretion discs like never before,
or maybe these galaxies could be playing
hide and seek with us,
maybe there's more to the story that we
haven't seen yet, after all the universe
is vast and mysterious and we've only
just begun to scratch the surface.
And whoa whoa whoa we really need to
slow down here
before we even try to explain all this
stuff, we need to confirm whether these
ancient galaxies really are that old,
although even if they're actually just
supermassive black holes, it still shows
an astounding change.
I have to wait about a year to find out
one thing's for sure, the James Webb
Space Telescope has definitely taught us
a valuable lesson ,expect the unexpected,
and this is just the beginning of
unexpected.
Evil lava's team wasn't the only one who
made such a huge breakthrough,there's
also a team that claims that they've
unlocked the secrets of the universe's
past ,and that's worth two Nobel prizes.
Move over James Webb Space Telescope,
because this discovery came from an
antenna that's smaller than a fridge,and
costs less than five million dollars,
talk about space bargain hunting.
The astronomers caught this signal that
showed some surprises, it was coming from
the earliest stars of our universe, back
in the days when they were just
beginning to twinkle.
Dark Matter may have been at work and if
that's the case then we can really be on
the verge of a great discovery.
Imagine you're looking at the night sky
filled with stars,
but there's something else there that
you can't see,
it's like an invisible cloak that covers
the entire universe,
scientists call this mysterious stuff
dark matter.
Dark matter is like the ghost of our
world, it doesn't emit, absorb or reflect
any light, we can't see it with
telescopes or our eyes, that's why we
call it dark matter, but if we can't
detect it in any way,how do we know it
exists,because of its gravitational pull.
One day we noticed that our
understanding of how galaxies were
created was incorrect. According to our
calculations,they should have been some
chaotic gas, but something held them
together turning them into spirals like
some kind of invisible glue,
then we thought maybe this invisible
glue really exists.
If the moon was invisible we would still
suspect that it exists somewhere,because
its gravity affects the tides on Earth,
this is also the case with dark matter
its gravity influences the motion of
galaxies and other Cosmic objects, in
fact Dark Matter makes up a huge chunk
of the universe, about 27% of it, moreover
the normal matter we can see like stars,
planets and galaxies only make up about
5% of the universe, so even
though we can't see dark matter there's
actually more of it in the universe than
everything we can see.
Scientists are still trying to figure
out if Dark Matter exists and what it
can be made of.
Some theories suggest that it could be
made up of exotic particles that are
different from the particles that we're
used to,
others think that it might be some kind
of weird undiscovered form of matter
that doesn't interact with light at all.
Anyway it's an intriguing mystery and if
we ever confirm the existence of Dark
Matter, our understanding of our world
will change forever.
So now you can understand why the
excitement in the scientific Community
is palpable, if this discovery is
confirmed then we will get the first
real proof of Dark Matter this discovery,
may be even more important than the Big
Bang itself, because as astronomers put
it we are made of star stuff, and so we
are glimpsing at our origin,
but of course we still have to wait and
explore all this in great detail, in
science one should never rush to
conclusions and while scientists study
this stuff we'll be here on the edge of
our seats waiting for the next space
Blockbuster to unfold.
The universe never ceases to amaze us
with its wonders,
who knew that such a small and humble
antenna could unlock such Cosmic secrets,
this goes to show that in the vastness
of space even the tiniest discoveries
can have the biggest impact keep looking
up and who knows what other Cosmic
surprises are waiting to be uncovered.
