Two sisters from Mukaiyama Elementary School in Ichinomiya, Aichi Prefecture, have discovered a supernova, becoming rising stars in Japan¡¯s astronomical society.
In December, 12-year-old Koto Tomita and her 9-year-old sister, Rino, spotted the stellar explosion together.
¡°We do not keep a record of the discoverer¡¯s age, but (Rino is) probably the youngest in Japan,¡± said a representative of the National Astronomical Observatory of Japan, based in Mitaka, Tokyo.
