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.
