To understand the formation and evolution of substellar objects light-years away, we must look for clues in their atmospheres. In particular, the population of ultra-hot Jupiters are irradiated enough to vaporize refractory material, opening a new window into giant planet formation through the first measurements of rock-to-ice ratios. WASP-178b is one such ultra-hot Jupiter. Here we present a first-look at WASP-178b's UV-to-IR transmission spectrum spanning 0.2-5.1 microns through 4 separate transits with HST/WFC3/G280+G102+G141 and JWST/NIRSpec/G395H. UV absorption spanning nearly 20 scale heights indicates the presence of metals in the planet's atmosphere, while H2O and CO absorption is evident in the IR. The abundance of refractory and volatile elements is retrieved within the PETRA framework, enabling preliminary constraints on the planet's formation.
