Peek Into The Universe's Secrets: James Webb Space Telescope Successfully Launched
After multiple delays and snags, NASA's groundbreaking James Webb Telescope was finally launched into space on December 25. Shot into space from the Ariane-5 rocket in Europe's Spaceport in French Guiana, the giant telescope is set to change our understanding of the universe.
Why James Webb is a gamechanger
Built by NASA in collaboration with European Space Agency and Canadian Space Agency, the large infrared telescope has a 6.5 metre primary mirror.
?This is thrice the size of Hubble Telescope's mirror, implying that James Webb would be able to capture far-off cosmos in richer detail than ever before. It'll also capture six times more light than Hubble and is being touted as 100 times more powerful.

In fact, the James Webb telescope would offer us a glimpse into the past. Hubble offers us a look at galaxies and stars as they formed 400 million years after the Big Bang. James Webb would be able to see the universe that existed 250 million years (perhaps even 100 million years) after the Big Bang, bringing us closer to the starting point of the universe.
?With eyes set on the universe's earliest stars and galaxies, NASA hopes to understand the origin of our planet and the universe better.?In addition, James Webb would add more detail to images including realistic light, better structure, and even faint spiral arms.
World's most awaited telescope launch: James Webb!
All of universe is constantly expanding, meaning objects are constantly moving farther away from each other. With its infrared imaging, James Webb would be able to see ancient galaxies by following a red trail in a process called "redshifting." When this happens, light is stretched each time it appears and disappears, leaving behind a red trail. And voila, a galaxy we had never seen before!

The James Webb Telescope took over $10 billion to build and was marred with delays and last-minute issues that pushed its launch date to Christmas. It'll be situated extremely far away from Earth - roughly four times the distance between the Earth and Moon.??
After the successful launch, the James Webb telescope would travel for nearly a week, unfurling its solar panels slowly to 24 metres. Are you excited to see what secrets James Webb reveals to us? Share your thoughts with us in the comments below.
