ESA Successfully Launches Euclid Telescope to Explore Secrets of the Universe
The European Space Agency (ESA) made a significant stride towards unraveling the mysteries surrounding the birth of the universe with the successful launch of the Euclid telescope. Departing from the Kennedy Space Center in Cape Canaveral, Florida, the telescope was carried into space by the SpaceX Falcon 9 rocket, taking off at 0:12 am on the 2nd.
Euclid’s primary mission is to investigate the enigmatic realms of dark matter and dark energy, gaining insight into the accelerated expansion of the universe. These elusive entities account for a staggering majority of the cosmos, with dark energy constituting approximately 68% and dark matter making up another 27%. In contrast, celestial objects that we can perceive, such as stars, planets, and gases, make up a mere 5% of all known substances.
Having now rendezvoused with the James Webb Space Telescope at the second Lagrangian point (L2) nearly a month after its launch, Euclid will undergo seven months of rigorous testing. L2 presents a unique gravitational equilibrium between the Earth and the Sun – a position that offers unparalleled stability to observe the cosmos.
Captivatingly, Euclid boasts a field of view 200 times wider than the Hubble Space Telescope, empowering its ability to observe galaxies situated an astounding 10 billion light-years away. In harnessing these observations, Euclid Consortium scientists have initiated the monumental task of constructing a comprehensive 3D map of the universe spanning an incredible 10 billion years. By analyzing the map, they hope to shed light on the phenomenon of gravitational lensing – a distortion of light caused by the gravitational influence of celestial bodies that lie between distant galaxies.
The Euclid Space Telescope, heralded as a beacon of scientific progress, plans to release its first set of observations in October. Excited about the prospects of this milestone, ESA Director Joseph Aschbacher declares, “The Euclid telescope embarks on a new scientific endeavor aimed at addressing the most captivating questions of modern science.”
With the Euclid telescope poised to propel humanity towards unraveling the intricacies of our universe, scientists eagerly anticipate the revelations it may bring regarding the birth and expansion of our cosmic home.
ESA “We will discover the secret of the birth of the universe by exploring dark matter and dark energy”

The Euclid Space Telescope was launched with a mission to reveal the secrets of the birth of the universe and the cause of the accelerated expansion of the universe.
The European Space Agency (ESA) successfully launched the Euclid space telescope aboard the SpaceX Falcon 9 from the Kennedy Space Center in Cape Canaveral, Florida, USA at 0:12 am on the 2nd, Korean time.
Euclid will reach the second Lagrangian point (L2) where the James Webb Space Telescope is located a month later and will be tested for seven months. The second Lagrangian point is the point where the gravitational forces of the Earth and the Sun are balanced and the gravitational force becomes zero, and this is the position where the space telescope can observe the universe stably.
The Euclid Space Telescope aims to explore dark energy and dark matter. Among the substances that exist in the universe, only about 5% of celestial objects such as stars and planets and gases are the substances that humans can see. Scientists explain that the remaining 68% of the universe is dark energy and 27% is dark matter.
According to the theory, dark energy is an ‘unknown force’ that has not yet been explored, and is thought to be the force that accelerates the expansion of the universe. Dark matter is a concept put forward to explain gravitational phenomena in the universe that cannot be explained by the action of visible matter. Axion, WIMP, etc. have been mentioned as candidates for dark matter, but nothing has been properly observed or revealed. Scientists hope to explain the birth and expansion of the universe by identifying dark energy and dark matter.
The Euclid Space Telescope has a field of view 200 times wider than the Hubble Space Telescope, allowing it to observe galaxies 10 billion light years away. Euclid Consortium scientists plan to use the observational results to construct a 3D map of the universe for 10 billion years and then analyze the gravitational lensing phenomenon that appears on the map.
Gravitational lensing is a phenomenon where light from galaxies or celestial bodies billions of light years away is slightly distorted by the gravitational influence of other celestial bodies in between. “If we remove the influence of visible matter, like other celestial bodies, from the gravitational lensing phenomenon, we will be able to calculate the existence of dark matter or dark energy,” said project manager Giuseppe Laca Euclid.
The Euclid Space Telescope is due to release its first observations in October. Joseph Aschbacher, director of the ESA, said, “The Euclid telescope is the beginning of a new scientific attempt to answer the most interesting questions of modern science.”
