Ground-based telescopes were hampered by atmospheric distortions, which limited the clarity of observations. In 1969, the idea gained momentum when NASA launched the Orbiting Astronomical Observatory-2 (OAO-2), which successfully demonstrated the potential of space telescopes. Subsequently, NASA collaborated with the European Space Agency (ESA) to develop the Hubble Space Telescope. Named after Edwin Hubble, whose discoveries confirmed the existence of galaxies beyond the Milky Way, the telescope was designed to capture high-resolution images in the visible, ultraviolet and near-infrared wavelengths. The construction of the HST faced many challenges, including budgetary and technical constraints. problems. However, the collaborative effort of engineers, scientists, and astronauts resulted in the successful launch aboard the Space Shuttle Discovery on April 24, 1990. The first images revealed a defect in the telescope's primary mirror, causing a spherical aberration. This setback was resolved in 1993 through a maintenance mission that installed corrective optics, allowing the HST to reach its full potential. Scientific achievements The Hubble Space Telescope has profoundly influenced our understanding of the universe through a series of groundbreaking discoveries. One of his most significant contributions is the confirmation of the accelerated expansion of the universe, which led to the proposal of dark energy. By observing distant supernovae, Hubble provided crucial evidence of the increasing rate of expansion of the universe, challenging previous cosmological models. Additionally, Hubble played a crucial role in refining the Hubble constant, the rate of expansion of the universe. Precise measurements of Cepheid variable stars and other distance indicators have led to more precise estimates of this fundamental cosmological parameter. These measurements have implications for the age, size and ultimate fate of the universe. Hubble observations have also shed light on the formation and evolution of galaxies. Deep-field images, such as the Hubble Deep Field (HDF) and Hubble Ultra-Deep Field (HUDF), have revealed thousands of galaxies, some dating back to the beginning of the universe. These observations have provided information on galaxy formation, star formation rates, and the distribution of galaxies through cosmic time. Additionally, Hubble has contributed to our understanding of exoplanets and their atmospheres. By observing the transits of exoplanets through their host stars, Hubble detected atmospheric components such as water vapor, methane and other molecules. These discoveries are crucial for the study of potentially habitable worlds beyond our solar system. Current legacy..
