What is the current benchmark temperature for the coldest *ice* detected in the cosmos using JWST data?

Answer

Approximately 30 K (approx. -243 degrees Celsius)

Interstellar ice, likely mixtures of various common cosmic molecules detected using JWST data, registers at roughly 30 K, which translates to about -243 degrees Celsius, representing the current benchmark for the coldest detected ice.
