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

Arial photograph of the most recent eruption at the Holuhraun lava field in Iceland. 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 ...

Asteroid discovered by UH telescope to make close Halloween flyby

The Panoramic Survey Telescope & Rapid Response System (Pan-STARRS)

A large near-Earth asteroid named 2015 TB145, discovered on October 10 by the University of Hawaiʻi Institute for Astronomy’s Pan-STARRS1 Telescope atop Haleakala, Maui, will pass close to Earth on October 31. The asteroid has a diameter of approximately 1,300 feet, and will pass within approximately 300,000 miles of Earth. There is no possibility of this object impacting Earth. The ...

Journey through the universe in Gunther Hasinger’s new book


“When observing the sky on a very clear, dark night, the soft glow of the Milky Way with its thousands of stars can be seen with the naked eye. Over the centuries since Galileo Galilei first pointed a telescope at the galaxy in 1609, this awe-inspiring yet easily visible panorama was our cosmos, our celestial world. With each new scientific ...

Robotic laser astronomy on the rise

The ultraviolet Robo-AO laser originating from the Palomar 1.5-meter telescope dome.

The world’s first robotic laser adaptive optics system, developed by a team led by University of Hawaiʻi at Manoa astronomer Christoph Baranec, will soon find a new home at the venerable 2.1-meter (83-inch) telescope at Kitt Peak National Observatory in Arizona. This system, renamed Robo-AO KP, will be the world’s first dedicated adaptive optics astronomical observatory and will allow astronomers ...
