Taken on February 20, five different exposures made in rapid succession were used to created this tantalizing telephoto image. In combination, they reveal a wide range of brightness visible to the eye on that frigid evening, from the urban glow of the Quebec City skyline to the triple conjunction of Moon, Venus and Mars. Shortly after sunset the young Moon shows off its bright crescent next to brilliant Venus. Fainter Mars is near the top of the frame. Though details in the Moon's sunlit crescent are washed out, features on the dark, shadowed part of the lunar disk are remarkably clear. Still lacking city lights the lunar night is illuminated solely by earthshine, light reflected from the sunlit side of planet Earth.
I've seen many articles go up about this amazing image taken by the , from to to this article shared out by my friend ... which I absolutely love.
It's focused on explaining the science of this awesome image so students can better understand what's going on. To learn more about gravitational lensing and the "Einstein Ring" seen here, go read the article below. It's short and very easy to understand!

- California Institute of TechnologyStaff Scientist, 2012 - presentI'm a principle mission scientist on a NASA Small Explorer mission, the Nuclear Spectroscopic Telescope ARray (NuSTAR), the world's first focusing hard X-ray telescope. I "do science" (I mostly study supernova remnants like Cassiopeia A) now that NuSTAR is up in space, but I also help to develop and maintain the software down here on the ground that turns the bits and bytes coming down from NuSTAR into pictures and spectra.
