Guided by Visionary scientist
mokaku together we'll unravel the
universe's Secrets using infrared beams
the remarkable discoveries of jwst the
James webspace teles scope jwst has
embarked on an extraordinary space
mission it will transform our
understanding of the universe let's
discuss the three astounding discoveries
that have left scientists speechless
initially the telescope's observations
have led to a re-evaluation of the Dark
Ages it's a period following the big
bang when the universe was in an ocean
of Darkness jws sensitive instruments
have detected unexpected signals from
this stage it indicates star for in
Intergalactic activity that appears more
extensive than previously believed these
discoveries have sparked an outbreak of
scientific speech they transformed our
understanding of the universe's early
Evolution it is called into question
long-held beliefs secondly JW st's
capabilities extend beyond displaying
ancient galaxies its efficacy has
allowed scientists to survey extrasolar
planets it tracked the light of
exoplanets as they pass their host Stars
jwst has produced intriguing evidence of
their compositions this remarkable
achievement opens up new opportunities
for assessing the potential for life it
has observed exoplanets and studied the
various types of planetary conditions
thirdly jwst remarkable infrared
capabilities allow us to examine the
universe's Origins it revealed an
abundance of galaxies that formed a few
hundred million years after the big bang
it provided the opportunity to examine
galaxies in their formative phases it
contradicted our previous hypothesis
regarding the sequence of early Galaxy
formation the observable universe and
its boundaries have you ever thought of
the vastness of our universe consider
the universe to be a vast theater here
dazzling stars shine galaxies revolve
and Mysteries hide this vast expanse is
known as the observable universe it's a
realm that surpasses human comprehension
while adhering to the laws of nature the
observable universe is comparable to a
cosmic window through it we can observe
the cosmos as a whole this is possible
because instruments like telescopes
enable us to analyze the universe the
cosmic speed limit is known as the speed
of light it travels at an astounding
299,792,458
m/s so our perspective is restricted to
information conveyed by light over the
years to comprehend its operation
Envision the universe is a large dark
chamber here your telescope acts as a
flashlight the flashlights beam will
only reveal a small portion of the area
it illuminates through the telescope
this portion of the universe can be
observed the darkness is widespread we
cannot see what lies beyond the
boundaries of our perception according
to researchers the observable universe
spans approximately 93 billion light
years it is comparable to gazing into a
vast extent of reality it's a place
where Gala
stars and Celestial marbles unfold
however if the universe is only 13.8
billion years old how could something be
extended to 93 billion like years it is
a Divine mystery the expansion of the
universe resembles raisin bread baking
in an oven in this analogy consider
galaxies as raisins as the dough expands
the raisins become further and further
apart since the Big Bang this process
has remained constant galaxies continue
to drift further and further apart as a
result some galaxies are so distant that
the light they radiate hasn't even had a
chance to reach us it is comparable to
pursuing a train that had already left
this limit known as the particle Horizon
indicates the end of the universe that
can be observed and what do you know
instead of winding down the expanse of
the universe is accelerating dark energy
is a mysterious force that propels
galaxies apart it works to increase
their momentum in other words words some
galaxies will ultimately be driven
further apart they might move beyond the
observable universe's Edge what is
beyond this boundary the reality is that
we are clueless it is unknown territory
a realm concealed from our view it is
comparable to staring into the murky
distance without seeing what lies Beyond
according to many researchers Galaxy
clusters have yet to be discovered
unveiling ancient galaxies using data
gathered by jwst scientists have made a
new discovery it says that these
galaxies formed within 500 to 700
million years of the Big Bang it signals
the beginning of the universe for this
to make sense we need to consider that
the universe is
approximately 13.8 billion years old the
light emitted by these galaxies has been
traveling through space for billions of
years it is a conduit of information
from the past they were among the first
to illuminate the void following the Big
Bang it explains their importance this
period known as the Dark Ages is a key
period in Cosmic history by observing
these galaxies researchers hope to
comprehend the Dark Ages better these
galaxies are the universe's grandparents
they provide details on how the universe
began their light reveals much about the
early processes that formed modern
galaxies stars and systems comparison to
other cosmological observations the
findings of jwst reveal astounding
contrasts and comp comparisons with
other cosmological
observations the universe is a puzzle
with distinct components and each of
these observations serves as a clue we
can connect these Clues to understand
the cosmos better the Hubble Space
Telescope captured amazing pictures of
far off galaxies and Cosmic occurrences
the cosmic microwave background CMB
radiation which was discovered by Hubble
is an Afterglow of the Big Bang it's
like a cosmic fingerprint that lets us
see the young universe
jwst and Hubble work together to create
a more thorough understanding of the
universe the plank satellite is a
further Celestial Explorer it mapped the
CMV with remarkable accuracy providing
knowledge of the universe's early
characteristics and composition similar
to how jwst expands this knowledge by
investigating galaxies plank measures
the backdrop these findings overlap and
build on one another to provide a fuller
picture of the cosmos's evolution the
Sloan digit Sky survey sdss provided a
large 3D map of galaxies and Cosmic
structures researchers examined how
galaxies are distributed in how Cosmic
structures developed while sdss analyzed
large scale Cosmic structures jwst goes
deep it investigates the universe's
early stages they complement each other
enhancing the comprehension of cosmic
history the autoc comma large millimeter
submillimeter array Alma is another
ground-based Observatory
it explores star formation regions and
planetary systems while Alma observes
regions of the universe where stars and
planets are forming jwst extends This
research to the earliest epics these
findings intriguing comparisons
highlight the complexity of cosmic
research the universe is a multi-layered
story each observation adds a new aspect
jwst investigation of the earliest
