a glowing element named for two physicists who never glowed about it themselves

means Curium is a radioactive, silvery synthetic metallic element (atomic number 96), one of the actinides, first produced in 1944 and used chiefly as a power source in space probes.

from Named in honor of Marie and Pierre Curie, the pioneers of radioactivity research, by its discoverers at the University of California, Berkeley, who synthesized it in 1944. The naming deliberately echoed gadolinium, which honors the chemist Johan Gadolin — so curium took its place in the periodic table as a tribute element, the '-ium' ending being the standard suffix for metals. The Curie name itself comes from the French family of Pierre Curie.
