NASA is reportedly launching an operation to study charged particles in the Earth's atmosphere that would colour the skies above the US East Coast with blue-green and red clouds. Colours would be produced by sunlight interacting with chemicals like barium, strontium, and cupric oxide released in space. The colourful clouds would linger up to 20 minutes depending on atmospheric conditions, NASA said.
