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 […]

A Rocky Planet Around One of Our Galaxy’s Oldest Stars
University of Hawaiʻi Astronomers Using W. M. Keck Observatory Discover Ancient Magma World Orbiting a Chemically Unusual Star Maunakea, Hawaiʻi – “They should have sent a poet,” says Ellie Arroway in the film Contact as, suspended in outer space, she gazes upon a spiral galaxy. Almost all of the planets discovered to date (including the […]

Astronomers Spot Farthest Galaxy Known in the Universe
Maunakea, Hawaii – An international team of astronomers using W. M. Keck Observatory have spectroscopic confirmation of the most distant astrophysical object known to date. The researchers, led by Professor Linhua Jiang at the Kavli Institute for Astronomy and Astrophysics at Peking University, obtained near-infrared spectra with the Multi-Object Spectrograph for Infrared Exploration (MOSFIRE) on […]

Direct Image of Newly-discovered Brown Dwarf Captured
Maunakea, Hawaii – Astronomers using two Maunakea Observatories – Subaru Telescope and W. M. Keck Observatory – have discovered a key benchmark brown dwarf orbiting a Sun-like star just 86 light-years from Earth that provides a key reference point for understanding the properties of the first directly-imaged exoplanets. Subaru Telescope first detected and captured remarkably […]

16-year-old Cosmic Mystery Solved, Revealing Stellar Missing Link
The Blue Ring Nebula, which perplexed scientists for over a decade, appears to be the youngest known example of two stars merged into one Maunakea, Hawaii – In 2004, scientists with NASA’s space-based Galaxy Evolution Explorer (GALEX) spotted an object unlike any they’d seen before in our Milky Way galaxy: a large, faint blob of […]

Unexplained Brightness from Colossal Explosion
Maunakea, Hawaii – Astronomers have discovered the brightest infrared light from a short gamma-ray burst ever seen, with a bizarre glow that is more luminous than previously thought was possible. Its half-second flash of light, detected in May of this year, came from a violent explosion of gamma rays billons of light-years away that unleashed […]

Galaxies In The Infant Universe Were Surprisingly Mature
Maunakea, Hawaii – In the first and largest multi-wavelength survey of distant galaxies in the early universe ever conducted, an international team of astronomers has discovered that massive galaxies were already much more mature in the early universe than previously expected. The survey, called ALPINE (the ALMA Large Program to Investigate C+ at Early Times), […]
