Aleca Borsuk, a senior Mechanical Engineering student in the College of Engineering, worked with mentor, Kent Kobayashi, associate horticulturist in Tropical Plant and Soil Sciences at the College of Tropcial Agriculture and Human Resources, on a project which used artificial lighting to simulate amaranth grown in space. She presented this work at the Spring 2016 Hawai’i Space Grant Consortium Fellowship & Traineeship …

Are black holes the dark matter?

Left: This image from NASA’s Spitzer Space Telescope shows an infrared view of a sky area in the constellation Ursa Major. Right: After masking out all known stars, galaxies and artifacts and enhancing what’s left, an irregular background glow appears. This is the cosmic infrared background (CIB); lighter colors indicate brighter areas. The CIB glow is more irregular than can be explained by distant unresolved galaxies, and this excess structure is thought to be light emitted when the universe was less than a billion years old. Scientists say it likely originated from the first luminous objects to form in the universe, which includes both the first stars and black holes. Photo Credits: NASA/JPL-Caltech/A.

A few months ago the news about the discovery of gravitational waves from two merging black holes with about 30 solar masses each rippled through the scientific community and caused a lot of excitement even among non-scientists. Almost exactly 100 years after Albert Einstein predicted them, gravitational waves were finally observed, and also gave proof that black holes exist — …

Astronomers have found a unique object that appears to be made of inner Solar System material from the time of Earth’s formation, which has been preserved in the Oort Cloud for billions of years. Originally identified by the University of Hawaiʻi’s  Pan-STARRS1 telescope, C/2014 S3 (PANSTARRS)  is a weakly active comet a little over twice as far from the Sun …

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 …
