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.
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 ...
GJ 504 b's spectral type was originally projected to be late T or early Y, and a follow-up study estimated that a T8 spectral type was the best fit. [3] Its effective temperature is 512 ± 10 К (238.9 ± 10.0 ºC), much cooler than previously imaged exoplanets with a clear planetary origin.
Deadly wildfires have been raging across Hawaii and the island of Maui County - here’s what we know so far. ... News. Science & Tech. Shopping. Sports. Weather ...
An image of global sea surface temperatures acquired from the NOAA/ AVHRR satellite. The Advanced Very-High-Resolution Radiometer (AVHRR) instrument is a space-borne sensor that measures the reflectance of the Earth in five spectral bands that are relatively wide by today's standards.
Fatalities confirmed on Maui as firefighters struggle to bring devastating wildfires under control, Bevan Hurley reports
