Seeing Quadruple
Machine-learning Methods Lead to Discovery of Rare “Quadruply Imaged Quasars” That Can Help Solve Cosmological Puzzles Maunakea, Hawaiʻi – With the help of machine-learning techniques, a team of astronomers has discovered a dozen quasars that have been warped by a naturally occurring cosmic “lens” and split into four similar images. Quasars are extremely luminous cores […]

A ‘super-puff’ planet like no other
An Université de Montréal-led team of astronomers discovers that the core mass of exoplanet WASP-107b is much lower than previously thought possible for a gas-giant planet. Maunakea, Hawaii – The core mass of the giant exoplanet WASP-107b is much lower than what was thought necessary to build up the immense gas envelope surrounding giant planets like […]

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 […]

A Tale of Planetary Resurrection
Years after its detection, astronomers have learned that a planet called KOI-5Ab orbits in a triple-star system with a skewed configuration. Maunakea, Hawaii – Shortly after NASA’s Kepler mission began operations back in 2009, it identified what was thought to be a planet about the size of Neptune. Called KOI-5Ab, the planet, which was the second […]
