Interesting link considering what has been alleged of the red spot in Velikovskian literature. At www.jpl.nasa.gov/news/news.php?release=2014-391 … Jupiter's red spot is not another Venus in the making. The red colouration is due to chemicals broken apart by sunlight in the planet's uppermost atmosphere. This view has come about as a result of NASA and its Cassini Mission (see also www.nasa.gov/mission_pages/cassini/main/index.html). Laboratory experiments have reproduced the red colour. Ultra Violet light was used in order to simulate sunshine.
