New Record: Nearest Known Black Hole to Earth Discovered
Maunakea, Hawaiʻi – Astronomers using two Maunakea Observatories, W. M. Keck Observatory and the Gemini North telescope, have found the closest known black hole to our planet. Located a mere 1,560 light-years away from Earth in the constellation Ophiuchus, the black hole, named Gaia BH1, is three times closer to us than the previous record-holder. […]

Massive Stars’ Blasts Hitting Orion’s “Sword” Mapped in Unprecedented Detail Using Hawaiʻi Telescope
Maunakea, Hawaiʻi – Astronomers using W. M. Keck Observatory on Hawaiʻi Island have captured from Maunakea the most detailed and complete images ever taken of the zone where the famed constellation of Orion gets zapped with ultraviolet (UV) radiation from massive young stars. This irradiated neutral zone, called a Photo-Dissociation Region (PDR), is located in […]

Hawaiʻi Telescopes Help Uncover Origins of Castaway Gamma-Ray Bursts
Maunakea Observatories Aid in Revealing That Seemingly Lonely Bursts Came From Previously Undiscovered Galaxies in the Early Universe A number of mysterious gamma-ray bursts appear as lonely flashes of intense energy far from any obvious galactic home, raising questions about their true origins and distances. Using data from some of the most powerful telescopes on […]

Heaviest Neutron Star to Date is a ‘Black Widow’ Eating its Mate
Maunakea, Hawaiʻi – A dense, collapsed star spinning 707 times per second — making it one of the fastest spinning neutron stars in the Milky Way galaxy — has shredded and consumed nearly the entire mass of its stellar companion and, in the process, grown into the heaviest neutron star observed to date. The study […]

Director’s Message: Maunakea’s Future
Aloha, Today, Governor David Ige signed HB2024 into law, establishing a new governance and management structure for Maunakea by creating the Mauna Kea Stewardship and Oversight Authority. We believe this is a positive way forward, one that upholds our core principles,* is inclusive of the native Hawaiian community in decision-making, and is consistent with our […]

Making the Nearly Invisible, Visible: Astronomers Trace the Gas that Breathes Life into Galaxies
Maunakea, Hawaiʻi— Astronomers have developed a groundbreaking new method of seeing the massive, but barely visible gas tanks that fuel star formation. With this innovative technique, the researchers have created the first ever spatial maps of the enormous, translucent gas clouds that birth galaxies, shedding new light on galactic evolution and star formation in the […]

“Black Widow” Star Devours Its Rapidly Circling Companion
Finding Represents the Shortest-period Black Widow Binary Found to Date Maunakea, Hawaiʻi – In black widow star systems, a rapidly spinning dead star, called a pulsar, blasts its lower-mass orbiting companion with radiation, slowly evaporating it. Like their namesake spiders, the pulsars take advantage of their companions before destroying them, in this case by harnessing […]

Astronomers Discover Widest Separation of Brown Dwarf Pair to Date
Maunakea, Hawaiʻi – A team of astronomers has discovered a rare pair of brown dwarfs that has the widest separation of any brown dwarf binary system found to date. “Because of their small size, brown dwarf binary systems are usually very close together,” said Emma Softich, an undergraduate astrophysics student at the Arizona State University […]
