An international team of astronomers reports the detection of a new luminous quasi-stellar object, or quasar. The newly found object, designated SMSS J114447.77-430859.3 (or J1144 for short) turns out to be the most luminous ...
The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons—the subatomic particles that carry electricity—are elementary particles and cannot be split, fractions of electronic ...
