A newfound small white dwarf, called ZTF J1901+1458 and located 130 light-years from Earth, that is slightly larger than the size of the moon in diameter but 1.35 times the mass of our sun, making it both the smallest in size and largest in mass of any known white dwarf is seen in an undated illustration. It was discovered using Caltech's Palomar Observatory. Giuseppe Parisi/Handout via REUTERS ATTENTION EDITORS - THIS IMAGE HAS BEEN SUPPLIED BY A THIRD PARTY. NO RESALES. NO ARCHIVES.
