Abstract: Contemporarily, various telescopes have been constructer for cosmology observation. With this research, this
confirms once again the vital contribution of cutting-edge telescope technology in revealing the universe's
most profound secrets. This essay have outlined how James Webb Space Telescope(JWST)'s infrared
capabilities, FIVE-HUNDRED-METER APERTURE SPHERICAL RADIO TELESCOPE's record-setting
sensitivity at radio wavelengths, and EVENT HORIZON TELESCOPE's Earth-sized interferometric array
each make their own distinct contributions to modern astrophysics. The research features spectacular new
findings, ranging from earliest galaxy formation signatures, vast pulsar surveys, and direct imaging of black
hole event horizons for the very first time. These breakthroughs not only challenging current models but lead
the way for future technological and methodological advancements as well. In the future, advances in
detection sensitivity along with resolution are predicted to reveal dark matter distribution patterns and the
dynamics of cosmic evolution. Implications of this study are profound, providing the robust foundation for
future multi-messenger astronomy as well as a richer insight into universe's complicated nature.
1 INTRODUCTION
The history of telescope research dates back to the
19th century, and early attempts, such as Herschel's
use of thermonuclear reactors to detect infrared
radiation from stars (Battersby et al., 2018), were
limited by the technology and yielded only sporadic
results. In the 1940s, the development of radar
technology in World War II laid the foundation for
radio astronomy, Hay's team discovered solar radio
radiation, Cambridge Ryle's team developed
interferometer technology, and the Australian Radio
Physics Laboratory was the first to identify radio
sources such as the Crab Nebula. In the 1950s, the
Lovell 76-meter radio Telescope and the 305
Miarecibo radio telescope were built, opening the era
of large aperture. Infrared astronomy has experienced
a long exploration (Sullivan, 2009). In the 1960s due
to the lead sulphide detector, liquid helium cooling
technology breakthrough and rise, Johnson
established a near-infrared metering system, and Luo
developed a germanium bolometer to achieve mid-
infrared observation. In the 1970s, with the rise of
space infrared astronomy, Spitzer, Herschel and other
space telescopes broke through the atmospheric limits,
and in 2010 James Webb Telescope achieved 6.5
meters of gold-plated beryllium mirror deep space
observation (Tyson, 2002). The current Origin Space
telescope design uses a 5.9-meter 4.5-K cooled
primary mirror covering 2.8-588 microns, equipped
with a high-resolution spectrometer and polarimeter.
Radio telescopes reveal invisible phenomena such as
pulsars, interstellar molecules, and quasars; infrared
telescopes penetrate dust to observe star-forming
regions and galactic cores; and space telescopes break
through atmospheric interference to obtain full-
wavelength data. The Origin telescope will trace the
evolution of heavy elements in the universe, and the
feedback mechanism of galaxies, analyse the
formation of planetary systems through water vapour
and organic molecular spectroscopy and detect
biomarkers of exoplanet atmospheres (Leisawitz et al.,
2021). At the technical level, it promotes
breakthroughs in superconducting detectors, space

refrigeration, interference arrays, etc., at the
methodological level, it encourages the development
of multi-messenger astronomy and continues to
expand the boundaries of human exploration of
ultimate questions such as dark matter, dark energy,
and the origin of life.
Recent years have seen significant advances in
space exploration. Using the Event Horizon
Telescope (EHT) (Galison, et al., 2023), the shadow
and asymmetric accretion structure of the
supermassive black hole at the centre of the nearby
galaxy M87 has been directly observed for the first
time, confirming both the prominent light bending
and event horizon predicted by general relativity in a
strong gravitational field, and measuring the black
hole's mass to be approximately 6.5 billion solar
masses (The Event Horizon Telescope Collaboration
et al., 2019). By high redshift observations, the early
galaxies, which were the first groups of galaxies
formed hundreds of millions of years after the birth of
the universe, have been discovered, which revealed
the early star formation and assembly process, and
traced the evolution history of the neutral hydrogen
ionized by ultraviolet radiation during the cosmic
reionization period. Studies of exoplanets have thus
far uncovered a plethora of different types of
planetary systems, resulting in studies of the
composition of atmospheric rocky planets and more
indirect signatures, such as KBO dust aggregation in
protoplanetary disks. As well as the distribution of
dark matter correlating with galaxies through
gravitational lensing, there has been new information
from the observation of supernovae and the large-
scale structure of the universe on dark energy and the
accelerated expansion of the universe. These and
other discoveries have enhanced understanding of
black holes, how galaxies form, the beginning of the
universe and the likely circumstances for life beyond
Earth.
This essay will analyse the most advanced
telescopes from their principle of device, composition,
and detection and include the results of the detections
in recent years. In the article, this paper will do a
description of the telescope and, an analysis of three
different telescopes (Hubble-James Webb, FIVE-
HUNDRED-METER APERTURE SPHERICAL
RADIO TELESCOPE, and EVENT HORIZON
TELESCOPE-event horizon telescope), a
comparison between these telescopes including their
difference, common limitations and the prospects.
2 DESCRIPTIONS OF
TELESCOPE
A telescope is a scientific instrument that breaks
through the sensitivity, resolution and observation
band limits of human eyes or traditional detectors by
collecting electromagnetic radiation (including radio
waves, infrared, visible light, X-rays, etc.). Its core
principle is to focus electromagnetic waves and
enhance the detection ability of distant celestial
bodies. The radio telescope receives radio waves
(wavelength from 1 mm to 10 meters) with parabolic
antennas, and improves its resolution through
interference technology. The Event Horizon
Telescope (EHT) network comprising eight radio
baselines around the globe forming a millimetre wave
VLBI network achieved a resolution of 20
microarcseconds at a 1.3 mm wavelength and the
Earth-equivalent aperture capturing the black hole
shadow for the first time. Infrared telescopes
concentrate on astronomical objects releasing thermal
radiation in the range of 0.7 microns to 1 mm. To do
so, they need to overcome the thermal noise generated
by the instrument, which can be achieved through
deployment in outer space or ensuring deep
refrigeration; the James Webb Space Telescope
(JWST) comprises 18 pieces of gold-coated
beryllium mirrors arrayed to make a 6.5-meter mirror
(Kalirai, 2018), matched with to withstand the heat
using five-layers of sunshade makeup to reach an
operating temperature of 40K that can undertake for
the composition of the atmosphere in the first galaxies
as well as exoplanets utilizing near-infrared camera
(NIRCam) and mid-infrared instrument (MIRI) (Li,
et al., 2019). The planned Origin space telescope will
further expand the aperture to 5.9 meters, 4.5K low-
temperature design and interferometer technology,
the target tracking galaxy evolution and water
molecule distribution. Optical telescopes rely on
mirrors to collect visible light and correct
atmospheric disturbances through adaptive optics,
such as the Hubble Space Telescope with a 2.4-meter
primary mirror and a vacuum environment to achieve
0.1 arcsecond resolution, covering ultraviolet to near-
infrared bands; large ground-based equipment such as
the Keck Telescope uses a 10-meter spliced mirror to
improve light collection. X-ray telescopes require
nested grazing incidence mirrors to focus high-energy
photons, typically in the 0.1-10 KeV band detected by
Chandra Observatory through a hyperbolic mirror
structure. Space and ground-based cooperative
observation constitute an important mode of modern
astronomical research: space instruments avoid
atmospheric absorption and specialize in ultraviolet,

X-ray and far-infrared wavelengths; ground-based
facilities rely on high-altitude sites to reduce
atmospheric interference and push resolution limits
with interferometric array technology. Technology
trends focus on multi-sector innovation:
Interferometry, multi-band data integration (virtual
observatory cross-library analysis), detector
innovations (superconducting transition edge sensors,
quantum capacitance detectors to improve far-
infrared sensitivity), and automated sky surveys are
advancing cutting-edge exploration of everything
from exoplanet atmospheres to the distribution of
dark energy in the universe.
3 JAMES WEBB SPACE
TELESCOPE
James Webb Space Telescope (JWST) is currently the
biggest and most advanced space telescope, it has
been launched on December 25 2021, orbiting at the
second lagrange point (L2), which is about 1.5
million km from Earth, focusing on the observations
in the infrared band. James Webb Space Telescope
has a primary mirror that has a diameter of 6.5 meter
and consists of 18 hexagonal element, which made
out of beryllium and has a layer of gold-plated
material for the surface to improve infrared
reflectivity. Apart from its primary mirror, JAMES
WEBB SPACE TELESCOPE also have equipped a
visor block to block heat and light from the Sun, Earth
and moon, this ensures JAMES WEBB SPACE
TELESCOPE can work in an extremely low
temperature, thus increasing the sensitivity of infrared
observation. JAMES WEBB SPACE TELESCOPE
also have scientific instruments including the Near-
Infrared Camera (NIRCam), the Near-Infrared
Spectrometer (NIRSpec), the Mid-Infrared
Instrument (MIRI), and the Near-Infrared Imager and
Slitless Spectrograph (NIRISS), among others, for the
analysis of the spectra and imaging of celestial
objects (Gardner, et al., 2023).
JAMES WEBB SPACE TELESCOPE mainly
uses infrared wavelengths for detection, this allows it
to penetrate dust and gas to observe celestial bodies
from the early universe. It’s working principle
involves collecting weak infrared light through a
large primary mirror then using the scientific
instruments to analyse the result. For instance, the
NIRcam can capture images of distant galaxies and
star formation regions, while the NIRSpec can
analyse the spectra of celestial bodies and reveal their
chemical composition and physical properties
(Gardner, et al., 2023). A typical observation is
shown in Fig. 1 (NIRCam, 2024). In recent years of
exploration, JAMES WEBB SPACE TELESCOPE
has achieved many significant results, it discovered a
galaxy which has a redshift over 13 and only
330million years after big bang, given a name as
JADES-GS-z13-1. This discover provides important
clues for studying the epoch of reionization.
Additionally, JAMES WEBB SPACE TELESCOPE
has conducted detailed analyses of exoplanet
atmospheres, revealing molecular components such
as water vapor and carbon dioxide, which this analyse
also provides important useful information of
researches on other topic (finding potentially
habitable planets). The observations from JAMES
WEBB SPACE TELESCOPE have demonstrated the
characteristics of galaxies at different evolutionary
stages, assisting scientists in better understanding
how galaxies gradually evolve from their early stages
into the spiral and elliptical galaxies we see today
(Sutter, 2024).
Figure 1: Image of the first scientific observation by
JAMES WEBB SPACE TELESCOPE (NIRCam, 2024).
The discovery of JADES-GS-z13-1 has really
pushed the boundaries of what has been know today
and has thrown a curveball to the existing theories
about how galaxies are formed. Before this finding,
scientists thought that galaxies with such mass and
brightness couldn’t have come into existence so soon
after the Big Bang. This discovery hints that the
processes behind early galaxy formation might have
been a lot more efficient than ever imagined, leading
to some necessary updates in cosmological models.
Plus, thanks to the James Webb Space Telescope's
ability to see through interstellar dust, and can now
observe star-forming regions that optical telescopes
just can't pick up. By looking at the spectral
signatures from these areas, astronomers can figure
out the ages and compositions of different star
populations, giving the valuable insights into how
stars and planetary systems develop over time (Sutter,
2024). JAMES WEBB SPACE TELESCOPE, with
its advanced capabilities, is now being repurposed to
support future deep space exploration missions. In

TELESCOPE and EVENT HORIZON TELESCOPE

addition to its scientific objectives, the JAMES
WEBB SPACE TELESCOPE is being used to
monitor potential threats such as asteroid trajectories
and to assess the feasibility of extracting resources
from NEOs. In addition, it assists in the development
of technologies for long-term manned space flight,
including radiation shielding and life support system
optimization. These efforts are in line with broader
initiatives to establish a sustainable human presence
beyond Earth, such as the Moon Base and Mars
colonization projects.
4 FIVE-HUNDRED-METER
APERTURE SPHERICAL
RADIO TELESCOPE
Five-hundred-meter Aperture Spherical radio
Telescope (FAST) is the biggest single-aperture radio
telescope in the world, located at Guizhou province,
China, it is known for its massive 500 meters aperture
and one of the most sensitive radio telescopes in the
world. FIVE-HUNDRED-METER APERTURE
SPHERICAL RADIO TELESCOPE consist a
complex structure made up using few key
components such as the reflective surface, the feed
cabin and the feed support system. The reflective
surface is made up of thousands of triangular shaped
panels stitched together forming a huge sphere which
is used for collecting and reflecting the radio wave
received from the universe. The feed cabin is located
at the focal point of the reflective surface, it is
responsible for receiving the reflected signal and
locating the significant and accurate location via the
feed support system, this is for assuring the signal has
been received accurately. The design of reflective
surface and the technology used in the structure
allows FIVE-HUNDRED-METER APERTURE
SPHERICAL RADIO TELESCOPE to cover a larger
viewing area with a higher sensitivity and resolution.
As mentioned, FIVE-HUNDRED-METER
APERTURE SPHERICAL RADIO TELESCOPE
detects celestial bodies by receiving the radio waves
from the universe. Radio wave is one of the waves
included in the EM waves, radio wave has a longer
wavelength compared to other EM waves, while it
reaches the reflective surface of FIVE-HUNDRED-
METER APERTURE SPHERICAL RADIO
TELESCOPE, they will be reflected to the focal point
of the reflective surface where feed cabin is located
at. There will be a receiver in the feed cabin which its
main job is converting these radio waves signal into
electrical signals, and then these converted signals
will be then analysed and processed by a
sophisticated signal processing system. This
detection method allow FIVE-HUNDRED-METER
APERTURE SPHERICAL RADIO TELESCOPE
can observe objects and phenomena such as, pulsars,
Five-hundred-meter Aperture Spherical Radio
Telescope radio bursts and neutral hydrogen, that
optical telescopes cannot detect, while the design of
the feed cabin allows FIVE-HUNDRED-METER
APERTURE SPHERICAL RADIO TELESCOPE to
be fine-tuned during the observation process to suit
different observation needs, this well increased the
accuracy and efficiency of the observation process.
In the last few years, FIVE-HUNDRED-METER
APERTURE SPHERICAL RADIO TELESCOPE
has achieved some exciting breakthroughs in
astronomy. In terms of pulsar discovery, FIVE-
HUNDRED-METER APERTURE SPHERICAL
RADIO TELESCOPE already has successfully
discovered more than 800 new pulsars (Event
Horizon Telescope Collaboration, 2019; Event
Horizon Telescope Collaboration, 2022a). This huge
number of pulsars been found out also refreshed the
historical record of pulsar discovery and injected new
resources into the study of pulsar astronomy. Else,
FIVE-HUNDRED-METER APERTURE
SPHERICAL RADIO TELESCOPE has also
conducted in-depth research on Five-hundred-meter
Aperture Spherical Radio Telescope radio bursts
(FRBs) and detected hundreds of FRB bursts,
provided valuable data for revealing the origin and
nature of Five-hundred-meter Aperture Spherical
Radio Telescope radio bursts. In another section of
neutral hydrogen observation, FIVE-HUNDRED-
METER APERTURE SPHERICAL RADIO
TELESCOPE provides important clues for study of
large-scale structures and galaxy evolution of the
universe through the observation of neutral hydrogen
in the Milky Way. This research demonstrates the
strong capability of FIVE-HUNDRED-METER
APERTURE SPHERICAL RADIO TELESCOPE
and shows that it provides important data and
platforms for the next step of research.
As a major scientific and technological
infrastructure independently developed by China,
FIVE-HUNDRED-METER APERTURE
SPHERICAL RADIO TELESCOPE has not only
achieved world-leading scientific achievements in the
fields of pulsar astronomy and Five-hundred-meter
Aperture Spherical Radio Telescope radio burst
research, but also provided an important observation
platform for astronomers around the world. In the
future, FIVE-HUNDRED-METER APERTURE
SPHERICAL RADIO TELESCOPE will keep being
IAMPA 2025 - The International Conference on Innovations in Applied Mathematics, Physics, and Astronomy
168
a key player in exciting scientific areas like detecting
dark matter and finding sources of gravitational
waves. It will help to learn more about the universe
and discover its mysteries. Its continuous observation
and research will help scientists better understand the
origin, evolution and structure of the universe, and
provide new impetus and direction for the
development of astronomy.
5 EVENT HORIZON TELESCOPE
The Event Horizon Telescope (EHT) is a global
network of radio telescopes that connect multiple
radio telescopes distributed around the world through
a very long baseline interferometry (VLBI)
technology to form a virtual telescope with an
aperture the size of the Earth. This unique design of
structure allows EVENT HORIZON TELESCOPE
has an unprecedented high resolution and the ability
to observe structures at the event horizon scale of
black holes. The main components of EVENT
HORIZON TELESCOPE include the Atacama Large
Millimeter Array (ALMA) in Chile, Hertz Telescope
in USA, Submillimeter Array Telescope in Hawaii,
and the Antarctic Telescope. The result of these
telescopes works together, taking down the record of
radio waves emitted by celestial bodies and use the
atomic clocks to precisely to accurately updating the
data and finally using the supercomputer to
synthesize the high-resolution images. This global
collaborative approach allows EVENT HORIZON
TELESCOPE to transcend the limitation due to the
geographic and enable observations of the most
mysterious objects in the universe (Event Horizon
Telescope Collaboration, 2019).
The detection principle of the EVENT HORIZON
TELESCOPE is based on the observations of
millimeter wave band, where the Milky way is almost
transparent, this reduced the influence of interstellar
gas and material around the black hole on
observations. The core technology of EVENT
HORIZON TELESCOPE is the VLBI technology, it
records radio waves emitted by celestial bodies by
setting up telescopes at different locations and
accurately up dating using the atomic clocks. The data
is then will be transferred to a supercomputer for
processing, synthesizing the high-resolution images
through complex algorithms. This technique can
achieve an extremely high angular resolution,
sufficient to observe the structure of the event horizon
of a black hole. The high-resolution imaging of
EVENT HORIZON TELESCOPE allowed scientists
to directly observe the shadow of the black hole for
the first validated prediction of Einstein’s general
theory of relativity (Event Horizon Telescope
Collaboration, 2022b).
In the past few years, EVENT HORIZON
TELESCOPE has made significant achievements in
black hole imaging, black hole jet research, and
general relativity verification. In 2019, EVENT
HORIZON TELESCOPE released humanity's first
image of a black hole, showing a supermassive black
hole at the centre of the M87 galaxy. This
breakthrough provides direct evidence for the
existence of black holes and has attracted widespread
attention around the world. In 2022, EVENT
HORIZON TELESCOPE published the first image of
Sgr A*, the black hole at the centre of the Milky Way,
further verifying the predictions of general relativity.
In addition, EVENT HORIZON TELESCOPE also
studied the origin and nature of the jet stream of the
black hole, and found that the jet of the black hole in
the M87 galaxy is closely related to the strong
magnetic field. These discoveries provide important
clues for understanding the physical properties and
behaviour of black holes, and open up new directions
for the study of black hole physics and cosmology
(Event Horizon Telescope Collaboration, 2022c).
The first image is shown in Fig. 2.
The success of EVENT HORIZON TELESCOPE
not only provided direct evidence for the existence of
black holes, but also advanced several areas of
astronomy and physics. In the future, EVENT
HORIZON TELESCOPE plans to further expand its
network of telescopes, improve the resolution of
observations, and explore more details of black holes,
such as the rotation of black holes and the formation
mechanism of jets. These studies will provide new
perspectives and data support for black hole physics
and cosmology, further deepening current
understanding of the universe.

Telescope Collaboration, 2022c).

6 COMPARISONS
Three telescopesthe James Webb Space Telescope
(JWST), the Five-hundred-meter Aperture Spherical
radio Telescope (FAST), and the Event Horizon
Telescope (EHT)represent different observation
methodologies, built-in limitations, and promising
research directions, as outlined in the text above.
JAMES WEBB SPACE TELESCOPE, using its 6.5-
meter segmented primary mirror and advanced
infrared instrumentation (NIRCam, NIRSpec, MIRI,
NIRISS), operates chiefly in the infrared regime, able
to push through dust and gas to unveil the earliest
universe's galaxy clusters and star-forming regions;
but, because it uses infrared detection, it needs
extremely low operational temperatures, submitted to
as required by an advanced visor block structure in
protecting solar and Earthly heat inputs, both an
engineering achievement but at the cost of sensitivity
in terms of its spectral range. Alternatively, FIVE-
HUNDRED-METER APERTURE SPHERICAL
RADIO TELESCOPE, the largest single-dish radio
telescope in the world with its 500-meter reflecting
surface made up of thousands of triangular panels,
uses radio wavelength detection on observing pulsars,
Five-hundred-meter Aperture Spherical Radio
Telescope radio bursts, and the emissions of neutral
hydrogen inaccessible to optical telescopes; but,
FIVE-HUNDRED-METER APERTURE
SPHERICAL RADIO TELESCOPE’s conception
and function demand fine calibration of its feed cabin
support system in order to accurately convert the
signal, one problem serving as an echo of limitations
in terms of resolving power of the signal as well as
the practical limitations on constructing very large
apertures. Alternatively, EVENT HORIZON
TELESCOPE utilizes an international array of linked
radio telescopes in Very Long Baseline
Interferometry (VLBI), gaining an Earth-sized virtual
aperture in order to create unparalleled high-
resolution imagery of black hole event horizons, as
illustrated in its historic snaps of the M87 black hole
as well as Sgr A'; but, EVENT HORIZON
TELESCOPE’s observation regime is by nature
bounded in ability by the problems in coordinating
global data sets, the technological requirements of
atomic clock sampling, as well as in data synthesizing
procedures that limit the frequency as well as breadth
of accomplishable observation. Looking ahead, as
each telescope has extended the boundaries of current
knowledge about astrophysical phenomenathe

developments can lead towards better detection of
dark matter as well as gravitational waves, and
EVENT HORIZON TELESCOPE's network
expansion as well as improvement in resolution is
likely to unveil even greater details about black hole
dynamics as well as jet formation, together ushering
in an era of revolutionary astronomical investigation.
7 CONCLUSIONS
To sum up, the field of telescopes has come on in
leaps and bounds since the 19th century,
revolutionizing the capacity for observing the
universe. This paper discusses the cutting-edge
technology of three seminal telescopesthe James
Webb Space Telescope (JAMES WEBB SPACE
TELESCOPE), the Five-hundred-meter Aperture
Spherical Radio Telescope (FAST), and the Event
Horizon Telescope (EVENT HORIZON
TELESCOPE)with particular emphasis on their
foundational design principles, instrumental
structures, and detection methods. In the investigation,
it has been found out JAMES WEBB SPACE
TELESCOPE s infrared observing capability has
revealed nascent galaxies and exoplanetary
atmospheres, FIVE-HUNDRED-METER
APERTURE SPHERICAL RADIO TELESCOPEs
refined radio measurements have discovered in
excess of 800 pulsars and Five-hundred-meter
Aperture Spherical Radio Telescope radio bursts, and
EVENT HORIZON TELESCOPE’s global
interferometer has imaged black hole shadows for the
first time in history, confirming predictions central to
general relativity. Not only do these findings
demonstrate noteworthy technical advances in
detector technology and data combination but also
enhance current knowledge of galaxy assembly, star
formation, as well as the underlying astrophysics
processes. Ultimately, the research emphasizes the
transformative power of innovative designs in
expanding astronomical knowledge and suggests
promising areas for future dark matter, dark energy,
and the origins of life explorations
