There’s an object in space 25 times the size of Jupiter that’s stumped scientists for years. They haven’t been able to figure out if it’s a planet or a failed star. But scientists are one step closer to an answer thanks to the powerful James Webb Space Telescope. After analyzing data collected by the telescope, astronomers have uncovered unexpected new clues floating light years away from us: Salty clouds sitting in space as hot as some home ovens. And if this mystery isn’t enough, we have more to look forward to in this episode, including insights into the evolution of laughter and the burials of ancient human relatives.
