Here is a rarely captured form of a transient luminous event called a "blue starter" shooting up from the top of a thunderstorm cloud. The streamer zone above the starter is evident in the detail image. Blue starters are related to another form of transient luminous event called blue jets.


Camera: modified Canon XS dslr (infrared blocking filter removed), 800 ISO, 3.2 second exposure, 50 mm f1.8 lens.

Captured on Oct 20 2015 0315:35 UT +/- 3.2 seconds over eastern New Mexico.

A super Moon means at the same time a super Earth (for ‘Selenites’). Also, the magnificent lunar eclipse of September 2015 meant at the same time a solar eclipse for ‘Selenites’.
Okay, forget the ‘Selenites’, but imagine we are orbiting the moon and suddenly… there it is, the unmistakable blue planet. The sun is behind the earth disk, very close to the east edge. Would the real scene look like this imaginary picture? The chronology of events, e.g. continent position while the event, angle of projection of the shadows on the moon, etc, are probably far from being real, but anyway, some (at least to me) interesting questions arise:
Would the planet disk look reddish due to moon light reflection?
Would the artificial lights on the American continents be visible?
What about the brightness and thickness of the halo around the earth?
And what about its color?

Messier 31, The Great Andromeda Galaxy

It's amazing how far astrophotography has come in the last few decades. This image was taken with an off the shelf DSLR (a Nikon D810a) and an 80mm refractor (Esprit 80) at a dark sky site in south Florida. One and a half hours of 5 minute exposures stacked to reduce noise, shot at ISO 800. I'm amazed that the hot blue stars in the arms can actually be resolved in this image at full resolution.
