Celebrating 35 Years of Hubble's Cosmic Wonders

Introduction to the Hubble Space Telescope

The Hubble Space Telescope (HST) stands as a monumental achievement in astronomical science, launched into low Earth orbit by NASA on April 24, 1990. This sophisticated space observatory has been a crucial tool in advancing our understanding of the universe. Over its 35-year journey, Hubble has transformed from a promising scientific instrument to an iconic symbol of human curiosity and technological prowess. Central to its mission has been its capability to capture stunning images of the cosmos, ranging from the majestic beauty of distant galaxies to intricate structures within nebulae with exceptional clarity [1](https://www.bbc.co.uk/newsround/articles/cn05zrlvp2do).

Hubble's early years were marked by a significant challenge; the telescope's primary mirror had a minute but disastrous error in its curvature, resulting in blurred images. This flaw was corrected in 1993 during a daring shuttle servicing mission, where astronauts installed a series of small mirrors known as the Corrective Optics Space Telescope Axial Replacement (COSTAR), which corrected the distortion caused by the primary mirror [1](https://www.bbc.co.uk/newsround/articles/cn05zrlvp2do). This pivotal repair was a testament to human ingenuity and perseverance in the face of adversity, allowing Hubble to achieve its full potential.

Since overcoming its initial obstacles, the Hubble Space Telescope has contributed to some of the most significant astronomical discoveries. It has played a vital role in determining the rate of the universe’s expansion and, consequently, its age. By observing the brightness of variable stars in far-off galaxies, Hubble provided the data necessary for these groundbreaking calculations, pinpointing the universe's age at approximately 13.8 billion years [1](https://www.bbc.co.uk/newsround/articles/cn05zrlvp2do). Such discoveries have not only deepened our comprehension of the universe but have also offered a timeline of its very formation and evolution.

Beyond the realm of galaxies, Hubble has unveiled secrets closer to home. The telescope's finely-tuned instruments have discovered moons orbiting Uranus and Neptune that were previously unknown, and it has witnessed the birth of stars within 'Eggs,' the term for Evaporating Gaseous Globules [1](https://www.bbc.co.uk/newsround/articles/cn05zrlvp2do). These phenomena are dense regions within nebulae where dust and gases coalesce to prompt star formation. In observing these regions, Hubble has illuminated the complex processes that precede the birth of new stars and potentially, new planets.

Among its numerous other accomplishments, one of Hubble's most profound discoveries is the confirmation of supermassive black holes at the center of galaxies. By capturing high-resolution images of the mass and motion of stars close to the centers of galaxies, including our own Milky Way, Hubble has produced compelling evidence of the gravitational pull exerted by these invisible giants [1](https://www.bbc.co.uk/newsround/articles/cn05zrlvp2do). These findings have changed the way astronomers understand the influence of black holes on galaxy formation and dynamics, proving that these enigmatic objects play a crucial role in the architecture of all galaxy types.

The Launch and Early Challenges

The Hubble Space Telescope's journey began on April 24, 1990, with its launch heralding a new era in space exploration. However, the initial phase was fraught with challenges. Shortly after deployment, it became apparent that Hubble's primary mirror had a spherical aberration, causing the images it captured to be blurry. The defect was attributed to a tiny miscalculation during the mirror's construction [BBC Newsround]. This flaw was a significant setback, as the telescope could not perform its intended mission to deliver clear and sharp images of the universe. Nevertheless, the dedicated efforts of scientists and engineers at NASA would eventually rectify the issue, restoring Hubble's potential to make groundbreaking discoveries.

Determining the Universe's Age and Expansion

The age and expansion of the universe have long been subjects of immense curiosity and scientific inquiry. One of the key contributors to our understanding of these concepts is the Hubble Space Telescope. Launched on April 24, 1990, the Hubble has provided valuable insights that have helped physicists determine the universe's age to be approximately 13.8 billion years. This measurement was made possible through the observation of distant galaxies, allowing scientists to calculate the rate at which the universe is expanding. By examining the light from stars and galaxies far beyond our Milky Way, Hubble's observations have paved the way for precise calculations of cosmic expansion and age, unravelling mysteries that have intrigued humanity for centuries .

Hubble's contribution extends beyond merely marking the age of the universe; it has also revolutionized our understanding of how it is expanding. The telescope's ability to observe the brightness of stars in our galaxy and compare them with similar stars in distant galaxies provided crucial data. This information allowed scientists to measure what's known as the "Hubble constant," a critical parameter that quantifies the rate of expansion. With these findings, researchers could trace back the universe's history, refining previous estimates and confirming the accelerating expansion driven by dark energy. Such discoveries illustrate Hubble's pivotal role in cosmology and its contribution to reshaping our cosmic perspective .

Discovery of New Moons and 'Eggs'

The discovery of new moons around Uranus and Neptune is a testament to the Hubble Space Telescope's unparalleled capacity to deepen our understanding of the solar system. These distant celestial bodies, which had eluded detection for decades, were unveiled through the lens of Hubble, showcasing the telescope's power to reveal hidden aspects of our cosmic neighborhood. Hubble's observations have provided essential data, allowing scientists to learn more about the orbital characteristics and compositions of these moons, deepening insights into their origins and the forces that govern planetary systems.

In addition to discovering moons, Hubble's observations of 'Eggs' or Evaporating Gaseous Globules have expanded our understanding of star formation. These dense pockets within nebulae serve as birthing grounds for new stars. As they are subjected to intense radiation from nearby stars, these globules gradually erode, revealing nascent stars growing from within. Through Hubble's detailed imagery, astronomers have been able to observe these processes, offering valuable insights into how stars evolve from clouds of dust and gas into luminous bodies that light up the universe.

The findings made by Hubble, such as the discovery of moons and insights into star formation, underline the enduring significance of this magnificent observatory. By bridging gaps in our knowledge, Hubble continues to inspire fascination and delight within scientific and public spheres alike. Its contributions not only enhance our cosmic perspective but also fuel the imagination, as it broadens our understanding of what lies beyond Earth's borders.
