Aurora and Milky Way in a Little Sky
Explanation: Stepping stones seem to lead to the Milky Way as it stretches across this
little sky. Of course, the scene is really the northern hemisphere's autumnal
equinox night. Water and sky are inverted by a top to bottom, around the horizon
stereographic projection centered on the zenith above Lake Storsjön in Jämtland, Sweden. In the north the Milky Way arcs from east to west overhead as fall begins,
but the season is also a good time for viewing aurora.
Geomagnetic storms increase in frequency near the equinox and produce remarkable displays of northern lights at high latitudes, like the eerie greenish glow reflected in this watery cosmos.
