The Earliest Supermassive Black Hole and Quasar in the Universe
Maunakea Observatories Provide Key Observations The most distant quasar known has been discovered. The quasar, seen just 670 million years after the Big Bang, is 1000 times more luminous than the Milky Way, and is powered by the earliest known supermassive black hole, which weighs in at more than 1.6 billion times the mass of […]

Astronomers Measure Enormous Planet Lurking Far From Its Star
Gas Giant Takes 218 Days to Complete its Orbit Maunakea, Hawaii – Scientists aren’t usually able to measure the size of gigantic planets, like Jupiter or Saturn, which are far from the stars they orbit. But a UC Riverside-led team has done it. The planet is roughly five times heavier than Jupiter, hence its nickname […]
