Transforming the red planet to support life has long been a dream of science fiction. Mars is now too cold to support life. Its atmosphere is also too thin to protect any living organisms from harmful radiation. But a new study suggests that local conditions could be changed using an inch of ' aerogel ' – a synthetic and ultralight material made by taking a gel and replacing the liquid component with a gas.

The authors behind the paper,published in Nature Astronomy , claim the technique could produce habitable regions on the red planet and potentially allow life to develop and thrive thanks to photosynthesis – the process by which plants can convert sunlight into energy. But is this really the case? And, if so, should we do it?
