Recently discovered by astronomers, Pōniuā’ena is the second most distant quasar ever discovered. Its discovery sheds light on researchers’ theories regarding the formation of black holes.

The origins of black holes
According to the researchers, a black hole having emerged 13 billion years ago to reach these massive proportions today would have started with an initial mass equivalent to 10,000 times that of our The Sun is the most star close to Earth, from which it is about 150 million km apart. The Sun is located 8.5 kparsecs from the center of the Milky Way. In the classification of stars, the sun is a G2 type star.

Pōniuā’ena, the first quasar with a Hawaiian name
If the Hawaiians had already given to the which we are part of the name of Laniakea (“Immeasurable celestial horizon”), or 1I / 2017 U1 the most singing appellation of Initial (“Scout”, or “messenger”), they had never had the opportunity to pass on part of their heritage by appointing a quasar. It is now done with the baptism of Pōniuā’ena, which means “invisible source of creation surrounded by light”.
The quasar was discovered after a long work of clearing the data collected by the telescope world today. It is part of the Mauna Kea observatory. “Data-url =” https://news.google.com/sciences/definitions/univers-observatoire-keck-4768/ “data-more =” Read the definition “> confirm its existence. ” Gemini’s preliminary data suggested it would likely be an important discovery. Our team had observation slots planned only a few weeks later at the Keck, perfectly on time to observe the new quasar with the Nires of the observatory, to confirm its extremely marked and measure the mass of his black hole Says Aaron Barth of the University of California.of the United Kingdom (Ukirt), on the Mauna Kea, and the panoramic survey (Pan-Starrs), on the island of Maui.
