Chinese nasa wallpaper11/24/2023 ![]() ![]() Messier 66 galaxy located at a distance of about 35 million light-years in the constellation of Leo by Hubble Space Telescope. The competition for the telescope is intense, as only a fifth of the proposals for where to point its gaze are ultimately accepted. Especially, for public use, anyone can uses the telescope there are no nationality or academic restrictions. It has become a symbol of human curiosity and our insatiable desire to explore and understand the cosmos. Credits: ESAĪs we reflect on its extraordinary achievements, it is important to note that the Hubble Space Telescope’s impact extends far beyond its scientific contributions. The frames included galaxies billions of light years away and generated a wealth of scientific data about the creation of the universe. The Hubble Deep Field, Hubble Ultra-Deep Field, and Hubble Extreme Deep Field constituted three unique windows on the Universe exploiting the visible sensitivity of the HST, images of small samples of the sky were obtained – the deepest ever obtained in this wavelength. NASA’s Hubble Space Telescope has revisited the famous Pillars of Creation, Credit: NASA, ESA Far far and even farther These observations have provided valuable insights into the diversity of planetary systems and the conditions necessary for life to exist elsewhere in the universe. With this method, it is possible to analyze the gases that make up the atmospheres of these fascinating planets, thus evaluating the possible presence of organic material. By observing the slight lowering of a star’s light as an exoplanet passes in front of it, known as the transit method, the HST has helped identify and characterize numerous exoplanets. The HST has significantly contributed to the study of exoplanets and planets orbiting stars beyond our solar system. Comparison image of the core of the galaxy M100 shows the improvement in Hubble Space Telescope’s view after STS-61. ![]() After the launch of Space Shuttle Discovery in 1990, 5 Space Shuttle missions repaired, upgraded, and replaced systems on the telescope, including all 5 of its primary instruments. Hubble is the only telescope designed to be modified in orbit by astronauts. In this way, the 7 astronauts of STS-61 saved Hubble’s life. The Repair Mission flew onboard Space Shuttle Endeavor in December 1993 and involved several specialized tools and equipment being installed over more than 10 days of hard EVAs ( extravehicular activities). Astronauts of the repair mission STS-61 working on the telescope. So, the idea of the most ambitious repair mission performed by hand in space. The importance of the defect was very high as it made a million-dollar project practically unusable. Once launched in 1990, a problem was discovered with the primary mirror, which had been incorrectly excavated, compromising the telescope’s capabilities as images were blurry. Nowadays, the HST is estimated to have generated 15 times the data obtained from a 4-meter ground-based telescope, underscoring its efficiency. The HST has also played a crucial role in refining the measurement of the Hubble constant, a fundamental value that determines the universe’s age and rate of expansion. By observing distant supernovae, the Telescope has provided evidence for the accelerating expansion of the universe, leading to the discovery of dark energy, an enigmatic force shaping the fate of the cosmos. In years of activity, over 9,000 reports based on data from the space telescope were published.

Hubble space telescope launch on board of Space shuttle Discovery during STS-31. Its high-resolution cameras and precise optics have revealed the intricate details and charming beauty of objects billions of light-years away. From vibrant nebulae and swirling galaxies to distant star clusters and planetary systems, the HST has provided humanity with unprecedented views of the cosmos. Hubble has recorded some of the most detailed visible-light images ever taken. Placing a telescope in Earth’s orbit has strong advantages as it allows to obtain extremely high-resolution photos it is, in fact, possible to remove the noise due to the atmosphere, which afflicts telescopes on Earth.
