Launched on December 25, 2021, the James Webb Space Telescope (or Webb) has the potential to revolutionize astronomy, astrophysics, and other space sciences forever. Last month, the first images from Webb were transmitted back to Earth, and what they show is astonishing.
On Saturday, August 20, the Mission Viejo Library held the James Webb Space Telescope: First Images Revealed event, which showcased the preliminary images received from Webb as well as a live presentation by NASA Solar System ambassadors alongside expert comments and conclusions from video panelists.
Webb works by using infrared light (or heat, imperceptible to the human eye), to view and capture images from deep space. This new technique complements the Hubble telescope, but it also allows Webb to see extremely far away at distances over 13 billion years away – nearly as old as the universe itself!
One of my favorite images from the presentation was the Carina Nebula, shown to the left. The James Webb Telescope has captured the first image of a star actually being born in a stellar nursery, confirming scientific theories while also raising new questions about the details of star birth.
I also liked the picture of the deep space field, shown to the right. Although the brightest stars are “photobombing” the image, since they’re part of the Milky Way galaxy, some of the smaller and dimmer spots are actually never-before-seen galaxies, part of the ancient world formed just after the creation of the universe. The curves near the center of the image also show concrete proof of gravitational lensing (or the curving of space-time as theorized by Albert Einstein).
Despite all of these fascinating discoveries, Webb is far from finished. Not only is there so much left to be discovered and explained about the images it has already sent, it is projected to last for a decade or longer, so it will undoubtedly unveil more and more about the universe we live in. Overall, I really enjoyed the Webb event, and look forward to presentations like this in the future.
