Philip von Doetinchem, a University of Hawaiʻi at Mānoa physics assistant professor, has won a prestigious National Science Foundation CAREER award for his project, “Dark Matter Identification with Cosmic-Ray Antideuterons,” which is expected to total $708,390 for five years. Doetinchem’s research program is focused on the study of cosmic rays, charged particles originating from violent events deep in outer space. ...

Mystery of disappearing asteroids solved

Artist’s impression. An asteroid’s orbit is altered as it passes close to Jupiter, Earth or Venus, such that its new orbit takes it near the Sun. The intense heat from the Sun causes the asteroid’s surface to expand and fracture, and some of the material breaks off. As the surface material disintegrates, it creates dust and pebbles that spread out along the asteroid’s orbit with time. If the orbit of the dust and pebbles ever intersects Earth, it can create a meteor shower. Art by Karen Teramura.

Ever since it was realized that asteroid and comet impacts are a real and present danger to the survival of life on Earth, it was thought that most of those objects end their existence in a dramatic final plunge into the Sun. A new study published on Thursday in the journal Nature finds instead that most of those objects are destroyed in a ...

Pan-STARRS chases source of LIGO gravity wave event

Pan-STARRS 1 Telescope

The email came in the evening of September 15. A potentially significant event had happened at the Laser Interferometer Gravitational-Wave Observatory, or LIGO, during their engineering run. A ripple in spacetime had occurred somewhere in the universe. But where? LIGO had not yet started their formal observing run, and with only two Gravity Wave detectors, one in Hanford, WA, and ...

The University of Hawaiʻi’s response to recent media reports that the Thirty Meter Telescope is now exploring alternative sites as a “Plan B” if it can’t build in Hawaiʻi: The University of Hawaiʻi remains steadfast in our support for locating the Thirty Meter Telescope in Hawaiʻi. The project is a tremendous scientific and economic opportunity for Hawaiʻi Island and the ...

The untold story of improvements in UH stewardship of Maunakea

The monitoring of archaeological sites is conducted annually according to the guidelines in the archaeological monitoring and burial treatment plans. Pictured here: A multiple upright shrine (kūahu) in the Maunakea Science Reserve.

This editorial by UH President David Lassner and UH Hilo Chancellor Donald Straney first ran in the Honolulu Star-Advertiser on November 29, 2015. Current controversies unfortunately overshadow the remarkable advances made in the stewardship of Maunakea. Critics often cite the 1998 State Auditor report on UH management. The university never disputed these findings, but viewed the report as a wakeup ...

The main-belt asteroid (493) Griseldis was probably hit by another object last March. So concluded a research group led by University of Hawaiʻi at Mānoa astronomer David Tholen. The results were reported on November 12 at the annual meeting of the Division for Planetary Sciences of the American Astronomical Society near Washington, DC. Observations taken with the 8-meter Subaru Telescope ...

UH researchers shed new light on the origins of Earth’s water

A proportion of the water released as vapor during this eruption is thought to be sourced directly from the Icelandic mantle plume. Dr. Hallis and her colleagues measured Icelandic and Baffin Island rocks where plume water was trapped inside the rock, rather than released into the atmosphere. Photo by Magnús Tumi Guðmundsson.

Water covers more than two-thirds of Earth’s surface, but its exact origins are still something of a mystery. Scientists have long been uncertain whether water was present at the formation of the planet, or if it arrived later, perhaps carried by comets and meteorites. Now researchers from the University of Hawaii at Manoa, using advanced ion-microprobe instrumentation, have found that ...
