A Short Journey from the Heavens of Dark Sky Alqueva up to the Comet Lovejoy


| | | | |

In the movie sequence below, resulting in the final still picture above, we can dip into a short journey that starts in the land of Juromenha, in Dark Sky Alqueva Reserve, Alentejo, with a stargazer trying to find with their own eyes and binoculars the glowing green head of Comet Lovejoy. After a few seconds we will zoom in, entering in a real time lapse sequence capturing the slowly movement of the comet and their ion blue tail, made by ionized gas – gas energized by ultraviolet light from the Sun and pushed outward by the solar wind – while it is crossing some stars of Taurus constellation. Finally, we will zoom out in a final still photograph that shows the strong and huge green head of diatomic carbon (C2) – gas fluorescing in sunlight that produces the coma’s green color – as well as a wide view of the entire fainter bluish tail, with more then 5 million kilometers at the comet’s estimated distance of 75 million kilometers from Earth.
