Scientists find radioactive molecule in space for 1st time
Astronomers have detected the first radioactive molecule in space, believed to be from a stellar explosion that was visible in the 17th century by the naked eye. The molecule, Aluminium monofluoride, is made of Aluminium-26, a radioactive isotope of aluminium. The explosion had resulted from the merger of two stars, creating a red nova, a new class of eruptive stars.
