The primary scientific driver of SpeX was to provide maximum simultaneous wavelength coverage at a spectral resolving power which is well-matched to many planetary, stellar and galactic features, and at resolving power which adequately separates sky emission lines and disperses sky continuum.
Ground motion hazard map for Hawaii, based on a 2% probability of exceeding 0.2 second spectral acceleration at 5 Hz in 50 years. Spectral acceleration (SA) is a unit measured in g (the acceleration due to Earth's gravity, equivalent to g-force) that describes the maximum acceleration in an earthquake on an object – specifically a damped, harmonic oscillator moving in one physical dimension.
The W. M. Keck Observatory is an astronomical observatory with two telescopes at an elevation of 4,145 meters (13,600 ft) near the summit of Mauna Kea in the U.S. state of Hawaii. Both telescopes have 10 m (33 ft) aperture primary mirrors, and, when completed in 1993 (Keck I) and 1996 (Keck II), they were the largest optical reflecting ...
The ongoing eruption at Hawaii’s Kilauea volcano refuses to let up after scientists say the eighth eruptive episode began late Monday night and sent lava shooting high into the air.
The arrival of snow in the region is not uncommon, especially in higher elevations between 9,000 and 10,000 feet, Alan Reppert, senior meteorologist at AccuWeather shared with USA TODAY on Tuesday.
As artificial light forms a light cloud above the land, the excess light disrupts the clear pictures taken by the telescopes. On July 1, 2013, the Hawaii Night Sky Protection Act was initiated, affecting both the Big Island and Maui. A large difference between the Hawaiian islands and the mainland United States can be observed: street lighting.
This image of the central Pacific, captured on Friday, Apr. 12, 2024, shows the storm with its bright-colored clouds spinning northwest of Hawaii (lower center). Intense rain was occurring in the ...
Aerial view above HVO in 2009, nine years prior to the crater collapse and enlargement in 2018. The Hawaiian Volcano Observatory (HVO) is an agency of the United States Geological Survey (USGS) and one of five volcano observatories operating under the USGS Volcano Hazards Program.
