Using the Dark Energy Camera (DECam), Argentinian astronomers have investigated the environment of a galactic globular cluster known as NGC 6355. The study, presented in a paper published May 2 on the pre-print server arXiv, ...
The Gum Nebula is an emission nebula almost 1400 light-years away. It's home to an object known as "God's Hand" among the faithful. The rest of us call it CG 4.

Darkness, in contrast with brightness, is a relative absence of visible light. It is the appearance of black in a color space. When light is not present, rod and cone cells within the eye are not stimulated. This lack of stimulation means photoreceptor cells are unable to distinguish color frequency and wavelength. The resulting perception is achromatic and in the case of darkness, black. The emotional reaction to darkness has metaphorical importance in many cultures.
