Astronomers used JWST and TESS telescopes to study nearby brown dwarf HD 19467 B

Brown dwarfs are objects between planets and stars. Astronomers divide them into 3 categories according to their temperature - L, T, Y. Their relatively low temperatures and brightness allow them to stay hidden for most part. Only the most powerful infrared telescopes are able to see them and that is where James Webb Space Telescope comes in.
