HTTP:: WISE Will Soon Hunt the 039 Ninjas 039 of the Skies
--------
In their own time, ninjas were perfect at hiding themselves in the shadows, and at navigating the darkness flawlessly, away from any light. However, in modern time, they would be easily discovered by a soldier wearing infrared goggles, as ScienceDaily accurately points out. In an attempt to translate this reasoning to the vastness of space, experts are currently building the most sensitive detector to date, which will have the ability to hunt elusive sky “ninjas” that hide in the dark and cold places between galaxies. The new instrument is called the Wide-field Infrared Survey Explorer (WISE), ScienceDaily reports. The new, wide-angle, orbit-based telescope will be able to detect even the dimmest traces of light or infrared-wavelength radiation coming in from the spaces between stars and galaxies. For a while, astronomers believed that these recesses of the skies were empty, but recent discoveries in the field taught them better than that. Vast dust clouds, brown dwarf!
stars, and large asteroids could all be lurking in these spaces. Experts say that large-scale asteroids heading for our planet could exist there as well, and thus the need for instruments to investigate these cosmic “dark spots” arises. “When you look at the sky with new sensitivity and a new wavelength ...
