Discovery of Exoplanets
Hubble has been instrumental in observing exoplanets, determining their composition, and analyzing their atmospheres. This helped in understanding the diversity of planetary systems.
Supernova 1987A
Hubble has observed the aftermath of Supernova 1987A over time, shedding light on how supernovae evolve and the complex structure of the remnants.
Galaxy Evolution
Hubble's deep field images reveal galaxies billions of light-years away, showing the evolution of galaxies from the early universe to today.
Black Holes at Galactic Centers
Hubble has provided evidence for supermassive black holes at the centers of galaxies, including our own Milky Way, changing our understanding of galaxy dynamics.
The Hubble Deep Field
The Hubble Deep Field image, taken in 1995, has shown some of the most distant galaxies ever observed. This provided a glimpse into the early universe.
Expansion of the Universe
Hubble's data provided evidence that the universe's expansion is accelerating, this unexpected discovery led to the theory of dark energy.
Gravitational Lensing
Hubble's observations of gravitational lensing have tested Einstein's theory of general relativity and helped to map dark matter in clusters of galaxies.
Identification of Pluto's Moons
Hubble was essential in discovering additional moons of Pluto beyond Charon, improving our knowledge of the Kuiper Belt and distant solar system bodies.
Composition of Planetary Atmospheres
Using spectroscopy, Hubble has analyzed the composition of the atmospheres of planets in our solar system, contributing to our understanding of planetary science.
Neutron Star Collision Afterglow
Hubble captured the light from a kilonova, an explosive event that occurs when two neutron stars collide, which is vital for understanding heavy element creation.
Age of the Universe
By observing distant stars and galaxies, Hubble helped to precisely calculate the age of the universe at about 13.8 billion years, using the Hubble constant.
Pillars of Creation
The iconic image of the 'Pillars of Creation' in the Eagle Nebula showcases newborn stars and is one of the most famous astronomical images captured by Hubble.
