Astronomers using the James Webb Space Telescope (JWST) may have identified the smallest star in the known universe — or at least, the smallest known object that began forming like a star, before fizzling out as a so-called brown dwarf.
"One basic question you'll find in every astronomy textbook is, what are the smallest stars?," Kevin Luhman, an astronomer at Pennsylvania State University and lead author of a new paper on the strange object, said in a statement. "That's what we're trying to answer."
