Yes, sweet potatoes can turn green when exposed to light for an extended period of time. This green coloration is due to the production of chlorophyll, which is harmless but can indicate the presence of a naturally occurring toxin called solanine. However, the levels of solanine in sweet potatoes are typically very low and would need to be consumed in extremely large quantities to cause toxicity. It is generally safe to consume sweet potatoes with green spots as long as the affected areas are cut away. **

Scientists study these variable stars to better understand their internal processes and evolution. **
