Rainbows on Venus

The ESA’s Venus Express orbiter has pictured a rainbow-like feature on Venus known as a glory. Not quite the rainbow we are used to seeing here on Earth. But glories can be seen on Earth too. Instead of an arch shape, a glory is circular with the colours in bands around a central bright core. In order for a glory to form it needs uniformly sized spherical particles (liquid drops). The atmosphere on Venus is thought to be full of sulphuric acid but the glory observed is not the same as would be expected from sulphuric acid and water. This has opened the suggestion of other elements at play in the Venusian atmosphere.
