Zooming in on Infant Planetary Systems
Like a raindrop forming in a cloud, a star forms in a diffuse gas cloud in deep space. As the star grows, its gravitational pull draws in dust and gas from the surrounding molecular cloud to form a swirling “protoplanetary disk.” This disk eventually further consolidates to form planets, moons, asteroids and comets.

If you think washing the mirrors and windows in your home is a daunting task, imagine cleaning two of the largest light-collecting surfaces in the astronomy world—the twin 10-meter Keck telescope mirrors. Keck Observatory’s two primary mirrors are each comprised of 36 hexagonal segments. Each segment is 1.8 meters, or 6 feet, in diameter, weighs […]

University of Hawaiʻi photographer R. David Beales won Best in Show at the University Photographers Association of America, or UPAA, competition for his December 2009 image “Mauna Kea Summit,” which features the W. M. Keck Observatory’s laser piercing the Hawaiian night sky. The Observatory was the first large telescope to apply adaptive optics for obtaining […]

One theory of this new exploding system, shown in the simulation images (above), is that a white dwarf steals helium from a companion until the mass thief becomes very hot and dense and a nuclear explosion occurs. The helium is transformed into elements such as calcium and titanium, eventually producing the building blocks of life […]

Laurie Goldstein, an artist in North Kohala, created her first work of art at age five. With a cardboard tracing of her foot, some ribbon and blue and gold paint, she crafted a pair of Grecian sandals. “I have no idea where I’d seen something like that or how I figured out how to make […]
