The HDF is an image of a small region in the Ursa Major constellation, showing a diverse range of galaxies and providing a deep look into the universe's past.

Hubble has observed numerous nebulae, providing detailed images that elucidate the complex processes of star formation and the remnants left behind by supernovae.

Hubble has discovered additional moons orbiting Pluto, significantly improving our knowledge of the dwarf planet's complex system and prompting further study.

The HUDF is an image of a small region of space in the constellation Fornax, containing an estimated 10,000 galaxies. This observation provided insight into the earliest and most distant galaxies ever observed.

Hubble was used to detect and study the composition of exoplanet atmospheres. This includes the detection of elements such as sodium, water vapor, and even organic molecules in some cases.

Hubble provided evidence that the universe is expanding due to the observation of redshift in distant galaxies. This supports the Big Bang theory and has profound implications for cosmology.

Hubble's observations of supernovae helped scientists discover that the universe's expansion is accelerating, leading to the hypothesis of dark energy -- a mysterious force that opposes gravity.

Hubble observed the second identified interstellar object, 2I/Borisov, as it passed through our solar system, allowing astronomers to compare its properties with those of solar system comets.

Hubble has provided evidence for the existence of supermassive black holes at the centers of many galaxies, including our Milky Way, which has increased our understanding of galactic dynamics.

The phenomenon of gravitational lensing, predicted by Einstein's General Theory of Relativity, has been observed by Hubble, allowing astronomers to study objects that are otherwise too faint or too distant to be seen.

Hubble has captured stunning images of colliding galaxies, shedding light on the process of galaxy evolution and the formation of structures in the universe.

Hubble has helped refine measurements of the Hubble Constant, the rate of expansion of the universe, which is essential for understanding the size, age, and fate of the cosmos.

The Hubble Space Telescope has been instrumental in detecting and characterizing numerous Kuiper Belt Objects (KBOs), providing valuable information about our solar system's outer reaches.

Using Hubble's measurements of cepheid variable stars and other distance indicators, astronomers have been able to better estimate the age of the universe at approximately 13.8 billion years.
