 University of Oklahoma Astronomer and Colleagues Identify 12 Billion-Year-Old White Dwarf Stars Only 100 Light Years Away

A University of Oklahoma assistant professor and colleagues have identified two white dwarf stars considered the oldest and closest known to man.
Astronomers identified these 11- to 12-billion-year-old white dwarf stars only 100 light years away from Earth. These stars are the closest known examples of the oldest stars in the Universe forming soon after the Big Bang, according to the OU researcher.
Mukremin Kilic, assistant professor of physics and astronomy in the OU College of Arts and Sciences and lead author on a recently published paper, announced the discovery.
Known as WD 0346+246 and SDSS J110217, 48+411315.4 (J1102), these stars are located in the constellations Taurus and Ursa Major, respectively.
