Double rainbow seen from space.

The glories are caused by diffraction of light back towards its source. The layer of stratocumulus clouds normally reflects a portion of solar energy into space and in this image the clouds are diffracting the sunlight back to the satellite splitting the light into its constituent colours. It has been suggested that enhancing the reflective property of stratocumulus clouds through geoengineering could help negate climate change. These glories look to us like the famous “double rainbow all across the sky” captured in Yosemite.

and triple hurricanes…
Massive solar storms, as clearly visible on the NASA Goddard Photo and Video‘s photo on the left, are sparking intense Northern Lights displays for skywatchers at high latitudes since yesterday. They are reported to be visible again tonight, as a wave of charged particles reaches Earth. You can find even more photos in our Aurora Borealis search with more pictures from last night.
And if you like space things… the Astronomy Photographer of the Year competition just opened the group for your entries.
