Explanation:
With this creative astro-collaboration you can follow the plane of
our Milky Way Galaxy as it bridges northern and southern
hemisphere skies.
To construct the expansive composite nightscape,
skies over Observatorio El Sauce in Chile (top)
were imaged on the same date but 6 hours later than
the skies over the Saint-Veran observatory in the French Alps.
The 6 hour time-lag allowed Earth's rotation to align
the Milky Way above
domes at the two sites.
All exposures were made with similar cameras and lenses mounted on simple
tripods.
A faint greenish airglow is visible in the
dark Chilean sky that also features the Large
and Small Magellanic Clouds near the observatory dome.
In the French Alps light pollution is apparent,
but the distant Andromeda Galaxy can still be spotted near the horizon
in the northern night.
On
planet Earth
the two observatories are separated by about 10,000 kilometers.
