Crepuscular Rays – One of our Favorite Pinterest Boards
Crepuscular Rays - One of the most spectacular views we get here on earth is the light show of crepuscular rays. These are sun rays or sunlight that has been scattered by particles in the atmosphere. Most often it is water, dust or smoke. Light is not visible so it takes some form of contaminant in the air to produce the ray effect.
APOD: 2014 December 19 - Reflections on the 1970s
The 1970s are sometimes ignored by astronomers, like this beautiful grouping of reflection nebulae in Orion - NGC 1977, NGC 1975, and NGC 1973 - usually overlooked in favor of the substantial glow from the nearby stellar nursery better known as the Orion Nebula.
NASA's Hubble Space Telescope photographed three magnificent sections of the Veil Nebula -- the shattered remains of a supernova that exploded thousands of years ago. This series of images provides beautifully detailed views of the delicate, wispy structure resulting from this cosmic explosion. The Veil Nebula is one of the most spectacular supernova remnants in the sky. The entire shell spans about 3 degrees on the sky, corresponding to about 6 full moons.
Satellites glimpse ultra-powerful “black hole” whirlpools in Atlantic
Satellites glimpse ultra-powerful "black-hole" whirlpools in Atlantic - The whirlpools - never witnessed before - would suck down ships, debris and even living creatures. Satellites have shown two mysterious 'black-hole' whirlpools in the South Atlantic Ocean - ultra-powerful "vortexes" (vortices) which suck water down into the depths
APOD: 2012 October 21 - The Horsehead Nebula
The Horsehead Nebula (Oct 21 2012) Credit & Copyright: Nigel Sharp (NOAO), KPNO, AURA, NSF Explanation: One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s. The red glow originates from hydrogen gas predominantly behind the nebula, ionized by the nearby bright star Sigma Orionis (...) #astronomy
Massive Star Makes Waves | The giant star #ZetaOphiuchi is having a "shocking" effect on the surrounding dust clouds in this infrared image from NASAs Spitzer Space Telescope. Stellar winds flowing out from this fast-moving star are making ripples in the dust as it approaches, creating a bow shock seen as glowing gossamer threads, which, for this star, are only seen in infrared light.
