Researchers used the MIRI instrument onboard the James Webb Space Telescope (JWST) to identify the presence of ultraviolet radiation in five young stars in the Ophiuchus region, and to understand its role in the formation of stars. The discovery of UV radiation around these protostars and its significant impact on the surrounding material is a challenge to models describing the formation of stars.
