The James Webb Space Telescope (JWST) celebrated its first birthday on Tuesday (12/7) by showing off a photo capture region which became the ‘star factory’.
“In just one year, the James Webb Space Telescope has transformed humanity’s view of the cosmos, peering into dust clouds and seeing light from distant corners of the universe for the first time,” said Bill Nelson, NASA Director. site official.
“Each resulting image is a new discovery, triggering scientists around the world to ask and answer questions they never imagined before,” he continued.
In celebration of his first birthday, Webb also released a photo which is the closest star forming area to Earth.
The region is only 390 light years away, allowing for close, highly detailed observations when there are no stars in space to get in the way.
“On its first birthday, the James Webb Space Telescope has fulfilled its promise to unveil the universe, gifting humanity with a treasure trove of stunning images and science that will last decades,” said Nicola Fox, associate administrator of NASA’s Science Mission Directorate.
“An engineering marvel built by the world’s leading scientists and engineers, Webb has provided us with a more complex understanding of galaxies, stars, and the atmospheres of planets outside our solar system than ever before, laying the foundation for NASA to lead the world in an era of new scientific discoveries and the search for habitable planets,” he added.
The Webb image shows an area containing about 50 young stars with a mass similar to that of the Sun or less. The darkest areas are the densest areas, where the thick dust clumps that still form protostars.
A large bipolar burst of molecular hydrogen, represented in red, dominates the photo, and is visible horizontally in the upper third and vertically in the right.
The bursts occur when a star first bursts through its cosmic dust shroud, ejecting a pair of opposing jets into space like a newborn baby first stretching its arms out to the world.
Meanwhile, star S1 is making a hole of glowing cosmic dust at the bottom of the photo. Star S1 is the only star in the photo that is much more massive than the Sun.
“Webb’s photo of Rho Ophiuchi allows us to see a very brief period in a star’s life cycle more clearly,” said Klaus Pontoppidan, Webb project scientist at the Space Telescope Science Institute in Baltimore, Maryland.
“Our own sun has gone through a phase like this a long time ago, and now we have the technology to see the beginnings of other stars’ stories,” he said.
