The Hubble Space Telescope (HST) was launched into space on April 24, 1990. It has changed how we see and understand the universe around us. Here are some of the amazing things it has done:
Deep Field Observations: In 1995, HST took a close look at a small area of the sky and found more than 3,000 galaxies in that tiny spot. This showed us that there are many more galaxies out there than we thought, and some of them are very, very far away—over 13 billion years!
Expansion of the Universe: Hubble helped scientists learn that the universe is growing faster and faster. This discovery pointed out the existence of something called dark energy, which is pushing the universe apart. This finding changed many ideas about how the universe works.
Formation of Stars and Galaxies: HST has been key in studying how stars and galaxies are born and change over time. It showed that new stars often form in thick clouds of gas and dust. Also, about 70% of stars are found in groups called clusters.
Exoplanet Studies: Hubble has looked at the atmospheres of planets outside our solar system, known as exoplanets. Using special methods, it found water vapor in some of these alien atmospheres. This discovery helps us explore the possibility of life beyond Earth.
Supermassive Black Holes: HST has been crucial in figuring out how massive supermassive black holes are in the middle of galaxies. So far, it has helped identify over 80 of these black holes, some of which weigh billions of times more than our Sun!
In short, the Hubble Space Telescope has changed how we view the universe. It has helped us learn more about its age, what it’s made of, and how it changes over time.
