Hubble has transformed our understanding of space by revealing the vastness and complexity of the universe, capturing detailed images of distant galaxies, measuring cosmic expansion, and providing insights into stellar formation and black holes.

• Finding Distant Galaxies: Hubble’s Deep Field images, like the Hubble Deep Field (HDF) and the Hubble Ultra Deep Field (HUDF), revealed thousands of galaxies in a tiny patch of sky, some as they were just a few hundred million years after the Big Bang.
• Measuring the Universe’s Expansion: Hubble’s observations of Type Ia supernovae in distant galaxies helped measure the rate of the universe’s expansion. This work led to the discovery of dark energy, a mysterious force driving the acceleration of this expansion.
• Detailed Pictures of Planets and Stars: The Hubble Space Telescope’s images of the Pillars of Creation, a part of the Eagle Nebula, showed stellar nurseries where new stars are forming, providing insights into the life cycle of stars.
• Studying Black Holes: Hubble helped observe the supermassive black hole in the center of the galaxy M87. This observation was crucial in confirming the presence of such black holes in many galaxies.

Hubble is important for astronomy because it provides crucial insights that ground-based telescopes cannot achieve, advancing our understanding of cosmic phenomena by avoiding atmospheric distortion and leading to groundbreaking discoveries.
