Fraser Cain<p>JWST Accidentally Found 21 Brown Dwarfs</p><p>JWST is the most powerful telescope ever built by humanity, and it's scanning into the very limits of the observable Universe to see the first galaxies coming together. However, as part of several galactic surveys, astronomers have already identified 21 brown dwarf candidates in the data, much closer to home. Some are as close as around 325 light-years, others as far as 13,700 light-years - farther than any brown dwarfs discovered. Quite a handy side-benefit.</p><p><a href="https://m.universetoday.com/tags/jwst" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>jwst</span></a> <a href="https://m.universetoday.com/tags/browndwarf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>browndwarf</span></a></p><p><a href="http://arxiv.org/abs/2309.03250" rel="nofollow noopener noreferrer" target="_blank"><span class="invisible">http://</span><span class="">arxiv.org/abs/2309.03250</span><span class="invisible"></span></a></p>
