Weather on exoplanets: Decoding the atmosphere of SIMP 0136
How can we study the weather on distant exoplanets? Researchers in Ireland have found a new way to track weather patterns on distant worlds. The planetary-mass object SIMP 0136 was the first target for the technique. Changes in temperature and the vertical structure of its clouds primarily shape the weather on SIMP 0136.

Studying weather on exoplanets and SIMP 0136 Astronomers said this month (September 15, 2026) they’ve found a way to decode weather on exoplanets. They used a new technique to look at a planetary-mass object called SIMP 0136. They found its weather is shaped primarily by changes in temperature and the vertical structure of its clouds. Exoplanets are worlds orbiting distant stars. A few decades ago, we hadn’t directly detected any. But today, using a variety of techniques, astronomers know 6,000+ exoplanets. They are all extremely far away, light-years beyond our solar system. And so they’re difficult to study. The researchers — at Trinity College Dublin in Ireland — said they used the James Webb Space Telescope (JWST) for their observations. They said other astronomers...
