Unveiling the Mysteries at the Edge of the Observable Universe

🔍The observable universe is a fraction of the entire universe and includes everything we can see, measure, and study from Earth or telescopes.

💫The James Webb Space Telescope (JWST) has the ability to peer back in time and discover unexpected objects from the early days of the cosmos.

🌌JWST recently discovered six massive galaxies that existed between 500 million and 700 million years after the Big Bang, challenging our understanding of early galaxies.

⏳By using infrared light, JWST can see objects that are invisible to our eyes and provide a glimpse of what the universe looked like billions of years ago.

🌠JWST has the potential to identify the oldest and farthest galaxies ever confirmed, providing insights into the early stages of the universe.

What is the difference between the observable universe and the entire universe?

—The observable universe is a small fraction of the entire universe that we can study and comprehend. The complete size and shape of the entire universe are still unknown.

How does the James Webb Space Telescope enable us to see back in time?

—The James Webb Space Telescope can see back in time by using infrared light to observe distant objects. Since light takes time to travel through space, we are observing these objects as they were in the past.

What did the recent discoveries by JWST reveal about early galaxies?

—JWST discovered six massive galaxies that existed between 500 million and 700 million years after the Big Bang. These galaxies are larger than expected, challenging our previous understanding of early galaxy formation.

How does JWST's use of infrared light contribute to its discoveries?

—JWST's use of infrared light allows it to detect faint glow from old stars and galaxies that have been around for ages. This provides valuable insights into the early stages of the universe and the formation of celestial objects.

What potential impact does JWST have on our understanding of the early universe?

—JWST has the potential to identify the oldest and farthest galaxies ever confirmed, providing unprecedented insights into the early stages of the universe and the processes that shaped it.
