The photograph depicts a lush green rolling hill with cirrus clouds during a daytime sky, with mountains far in the background. [1] [2] It was taken by Charles O'Rear, a former National Geographic photographer and resident of St. Helena, California, in the Napa Valley region north of San Francisco, while on his way to visit his girlfriend in ...
Webb's First Deep Field. Webb's First Deep Field is the first operational image taken by the James Webb Space Telescope (JWST). The deep-field photograph, which covers a tiny area of sky visible from the Southern Hemisphere, is centered on SMACS 0723, a galaxy cluster in the constellation of Volans.
Sky Above Clouds (1960–1977) is a series of eleven cloudscape paintings by the American modernist painter Georgia O'Keeffe, produced during her late period.The series of paintings is inspired by O'Keeffe's views from her airplane window during her frequent air travel in the 1950s and early 1960s when she flew around the world.
The sky is an unobstructed view upward from the surface of the Earth. It includes the atmosphere and outer space. It may also be considered a place between the ground ...
Scattering adds the sky light as a veiling luminance onto the light from the object, reducing its contrast with the background sky light. Sky light usually contains more light of short wavelength than other wavelengths (this is why the sky usually appears blue), which is why distant objects appear bluish.
C-BASS – On-going 5 GHz all sky survey to aid in the subtraction of galactic foregrounds from maps of the Cosmic Microwave Background; EMU – A large radio continuum survey covering 3/4 of the sky, expected to discover about 70 million galaxies; GMRT - The Giant Metrewave Radio Telescope's TGSS ADR mapped the sky at 150 MHz.
In astronomy, background commonly refers to the incoming light from an apparently empty part of the night sky.. Even if no visible astronomical objects are present in given part of the sky, there always is some low luminosity present, due mostly to light diffusion from the atmosphere (diffusion of both incoming light from nearby sources, and of man-made Earth sources like cities).
The night sky is the nighttime appearance of celestial objects like stars, planets, and the Moon, which are visible in a clear sky between sunset and sunrise, when the Sun is below the horizon. Natural light sources in a night sky include moonlight , starlight , and airglow , depending on location and timing.
