Coral - Rekindling Venus by Australian filmmaker Lynette Wallworth, released at the Nehru Planetarium here on Wednesday, throws light on the coral ecosystem and its role in combating global warming.

The film was released in full dome planetariums worldwide, including Mumbai, to mark the Transit of Venus and World Environment Day. It depicts the life cycle of a coral through vivid footage of fluorescent coral reefs as well as bioluminiscent sea creatures and other rare marine life most threatened by climate change due to warming sea temperatures.
