This video presents “Hopewell Rocks perseid meteor shower time lapse.”
NASA astronomers are asking viewers what are the “Mysterious Green Patches on the Sky,” as they ponder the significance of these green images.
Snair explained that the green ‘clouds’ result from airglow phenomenon which is very weak emission of light by Earth’s atmosphere so that the night sky is never completely dark.
Another airglow phenomenon was captured on 15 September 2011 in the following photograph featuring
NASA also included the following possible explanations for the mysterious green patches:
NASA JPL compresses a day into an hour using AWS with Intel.
NASA JPL engineers speed up Curiosity mission data analysis to leave more time for science and discovery by putting Amazon Web Services with Intel to work.

As Summer approaches in the Northern Hemisphere, we can look forward to enjoying more of the sun’s warmth and light. It is this light that allows to record pictures. This video from NASA distils 3 year’s of sun watching by NASA’s Solar Dynamics Observatory (SDO) into 3 minutes, at a pace of two images per day.

The Hubble Space Telescope, launched on April 24, 1990, has returned many stunning images of the cosmos. To celebrate its 23rd year, NASA used it to take a new — and stunning — infrared photo of the iconic Horsehead Nebula. The infrared photo was taken by the telescope’s Wide Field Camera 3 installed by spacewalking astronauts in 2009. The Hubble is expected to continue operating through April 2016. Its successor, the James Webb Space Telescope, is optimized to view in infrared light and is slated to blast off in 2018.
It only happens twice a century and, if you missed it, then regale yourself on this video as the next one is 105 years away, in the year 2117.
This video from NASA/SDO is beautiful but what I don’t understand is how Venus can look transparent as it transits across the sun. Optical illusion, perfectly legitimate scientific explanation or just a little bit of digital manipulation as the transit is superimposed on different pre-existing videos of the sun?
