Description

This time of the year the 4 closest planets are all visible simultaneously - allowing astrophotographers to "planet-hop" when imaging. This shows Venus (Jupiter, Saturn and Mars were also imaged) over a 2 hour period. To the naked eye they are mostly brighter than most stars, and are aligned along the ecliptic, the plane of the gaseous proto-planetary disk from which they condensed. This is my first attempt at Venus, a Hellish world with little detail visible due to the swirling clouds of sulphur dioxide and sulphuric acid, unless you have special UV filters. Venus however has clear 'phases' - the phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit - giving the earth-bound observers a sequence of progressive lighting similar in appearance to the moon's phases as Venus moves around the sun.
