Planetary scientists at Brown University have introduced an infrared spectroscopic method for studying olivine, a mineral that provides insights into the formation of the moon, Mars, and other planetary bodies. Informally dubbed “crossover spectroscopy,” the scientists deployed the technique to examine the spectral range in between the visible near-infrared (0.5 to 3 μm) and the mid-infrared ranges (8 to 15 μm). The researchers honed in on the 4 to 8 μm range, and, even more specifically, in the spectral features of olivine at 5.6 and 6.0 μm. A mountain peak at the...Read full article

    infrared
    Infrared (IR) refers to the region of the electromagnetic spectrum with wavelengths longer than those of visible light, but shorter than those of microwaves. The infrared spectrum spans wavelengths roughly between 700 nanometers (nm) and 1 millimeter (mm). It is divided into three main subcategories: Near-infrared (NIR): Wavelengths from approximately 700 nm to 1.4 micrometers (µm). Near-infrared light is often used in telecommunications, as well as in various imaging and sensing...
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
