Space Telescope Detects Hydrated Minerals in Numerous Asteroids

Facebook X LinkedIn Email
A Kobe University research team has detected the existence of water in a number of asteroids for the first time. Water is retained in the asteroids as hydrated minerals that were produced by chemical reactions occurring within the asteroid. By using a space-borne telescope, the team was able to successfully detect the presence of water in many asteroids. Courtesy of Kobe University. The spectroscopic survey was conducted using the infrared camera (IRC) on board the Japanese IR satellite AKARI, launched in February 2006. In the warm mission period of AKARI, observations were performed...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...
    astronomy
    The scientific observation of celestial radiation that has reached the vicinity of Earth, and the interpretation of these observations to determine the characteristics of the extraterrestrial bodies and phenomena that have emitted the radiation.
    telescope
    An afocal optical device made up of lenses or mirrors, usually with a magnification greater than unity, that renders distant objects more distinct, by enlarging their images on the retina.
