Pōniuāʻena (/ ˌ p oʊ n i uː ɑː ˈ ɛ n ə /), also named J100758.264+211529.207 or J1007+2115, is the third most-distant quasar known, with a measured redshift of z = 7.515 or a lookback time of 13.02 billion years.
2. Aug. 2020 · Der neu entdeckte Quasar J1007+2115 (Poniua´ena) gibt Rätsel auf. Sein Schwarzes Loch mit 1,5 Milliarden Sonnenmassen ist in der sehr frühen Phase des Universums (etwa 700 Millionen Jahre nach dem Urknall) nur schwer mit den gängigen Modellen erklärbar.
