The Hubble Space Telescope (HST) has changed how we see and understand the universe. Here are some important things it has helped us learn:
Expansion of the Universe: Hubble helped scientists figure out how fast the universe is growing. This is called the Hubble Constant. By looking at how far away galaxies are and how their light shifts, astronomers found out that the universe is expanding at a speed of about 73 kilometers per second for every megaparsec.
Finding Exoplanets: Hubble has been very important in finding exoplanets. These are planets that are not in our solar system. It helped us study the atmospheres of these distant planets and even found water vapor and other chemicals in some of them.
Deep Field Images: Hubble took amazing images called Deep Field pictures. These pictures show thousands of galaxies in just a small area of the sky. This helped us see how different galaxies are and how they form and change over time.
Dark Energy: Hubble's observations of certain types of exploding stars, called Type Ia supernovae, led to the discovery of dark energy. This is a mysterious force that is causing the universe to expand faster and faster.
Life of Stars: Hubble has captured beautiful images of colorful gas clouds called nebulae. These images show how stars are born and how they die, helping us understand the entire life cycle of stars.
All of these discoveries have not only increased our knowledge but also made us curious about our place in the universe.
