The EUV (100-912 Å) probes regions of the stellar atmosphere that are inaccessible from other spectral regions, including cool coronal emission lines that offer the clearest path toward detecting coronal mass ejections on stars other than the Sun. New EUV observations would require a dedicated grazing-incidence observatory.
