A 10,000 Kilometer Galactic Bridge

With this ingenious astro-collaboration you would possibly well presumably presumably follow the plane of our Milky Approach galaxy as it bridges northern and southern hemisphere skies. To fetch the immense composite nightscape, skies over Observatorio El Sauce in Chile (high) non-public been imaged on the identical date however 6 hours later than the skies over the Saint-Veran observatory in the French Alps. The 6 hour time-bolt allowed Earth’s rotation to align the Milky Approach above domes on the 2 web sites. All exposures non-public been made with same cameras and lenses mounted on straightforward tripods. A faint greenish airglow is considered in the tiresome of evening Chilean sky that moreover aspects the Wide and Little Magellanic Clouds shut to the observatory dome. In the French Alps light air pollution is obvious, however the some distance away Andromeda galaxy can restful be spotted shut to the horizon in the northern evening. On planet Earth the 2 observatories are separated by about 10,000 kilometers.
