NASA's Webb telescope detects the first potential brown dwarfs outside our galaxy
Brown dwarfs are bigger than gas giants, but smaller than stars -- and they barely produce any light. The James Webb telescope made it possible to detect them, even if they're 200,000 light years away.
The James Webb Space Telescope is making it possible to detect more celestial objects we previously wouldn't be able to, including ones that can further our knowledge on how our universe began. "Only with the incredible sensitivity and spatial resolution in the correct wavelength regime is it possible to detect these objects at such great distances," said Peter Zeidler, the team leader from AURA/STScI for the European Space Agency. Based on what they've seen, the cluster exists in an environment comparable to the early universe, which means studying the brown dwarfs could provide more clues on how stars and planets formed billions of years ago.
