New horizons for space exploration: how the James Webb telescope is revolutionizing our understanding of the universe
Often called humanity's most powerful space observatory, the James Webb Space Telescope (JWST) has already provided some of the most fascinating and unprecedented views of the universe. Launching in late 2021, it was designed to peer deeper into space, capturing data previously beyond our technological capabilities. As of 2024, the telescope continues to push the boundaries, discovering cosmic phenomena that challenge and expand our understanding of the universe.
In this article, we look at the 5 most groundbreaking discoveries made by the James Webb Telescope in 2024, each of which contributed to a new era of space exploration.
1. Discovery of the oldest galaxies ever observed
In 2024, the James Webb Telescope made headlines for the discovery of galaxies more than 13.5 billion years old, dating back only a few hundred million years after the Big Bang. These ancient galaxies, much older than any previously observed galaxies, offer unprecedented insight into the early stages of the universe. The discovery provides clues to how galaxies formed and evolved from their nearly chaotic beginnings to the structured universe we see today.

2. Revealing the secrets of exoplanet atmospheres
One of the most exciting features of the James Webb Telescope is its ability to analyze the atmospheres of exoplanets—planets that orbit stars outside our solar system. In 2024, JWST detected water vapor, methane and even carbon dioxide in the atmosphere of an exoplanet located in the star's habitable zone. These discoveries bring us closer to answering the eternal question: are we alone in the universe?

3. The first images of the space network
The improved resolution and infrared capabilities of the James Webb Telescope have allowed scientists to obtain the first clear images of the cosmic web, the vast network of filaments that stretch between galaxies and galaxy clusters. This network contains the vast majority of matter in the universe and plays a crucial role in shaping its structure. For the first time, astronomers can now observe the large-scale architecture of space with unparalleled clarity.

4. Discovery of new ideas about black holes
Webb provided a closer look at supermassive black holes at the centers of distant galaxies. One of the most impressive discoveries of 2024 was its ability to observe the chaotic environment around these black holes, showing how they interact with the surrounding matter and energy. This information can help us understand how black holes grow and influence the formation of galaxies.

5. Discovery of the most distant supernova ever recorded
In 2024, JWST detected light from a supernova explosion that occurred more than 10 billion years ago. This discovery allows researchers to study the remnants of these cosmic explosions, which play a crucial role in the distribution of elements in the universe, seeding future star systems. By better understanding the life cycle of stars, we can trace the history of the elements that eventually make up the planets and life itself.

Why are these discoveries important?
Every discovery made by the James Webb Telescope pushes the boundaries of what we know about the universe. From observing the formation of the oldest galaxies to analyzing the atmospheres of potentially habitable planets, the data provided by JWST is shaping the future of astronomy.
With new discoveries expected in the coming years, it is clear that this telescope will continue to play a key role in answering some of humanity's deepest questions.
