Two moons passing in the night
The Saturn moons Mimas and Pandora remind us of how different they are when they appear together, as in this image taken by NASA’s Cassini spacecraft. Pandora’s small size means that it lacks sufficient gravity to pull itself into a round shape like its larger sibling, Mimas. Researchers believe that the elongated shape of Pandora (50 miles, or 81 kilometers across) may hold clues to how it and other moons near Saturn’s rings formed.

#orion #m42 #nebula #astronomy #astrophotography
This is my second attempt at M42, the Orion Nebula. Still only one exposure because it was too windy to do any long ones, and I barely processed this. Given some more photos and some extra editing, I feel like I could be pretty good at this astrophotography thing.
you did a fabulous job :)

The Milky Way Band and Dark Skies
PSA:“That has to be superimposed - they photoshopped that on!” It’s understandable why a lot of you (and I do mean a lot) might be confused when confronting these vistas. But these are actual images of the milky way as seen under the best viewing conditions known to our planet, the dark skies. Due to the rapid growth of our civilization, we emit more light than we should and thus this darkens out many of our views and blocks us from making those wonderful necessary connections to the skies our minds desperately need. We can’t see the Milky Way band as seen above in many places, it’s always there though, rest assured, ready to greet us with its lovely stars. If we’re missing out on this.. is the way we use public lighting really as conventional as we believe it is?
