We’re gradually resuming more services in our branches. For health and safety reasons, access to installations in KidsStops and Discovery Zones is limited.
More about our reopening plan and available library services.
This week, we're answering a question that has been asked quite a few times by TPL Kids website visitors. We have all (probably) spent time in class gazing out the window and wondered: Why is the sky blue?
According to an article from NASA: Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
So next time you gaze up at a clear blue sky, consider how amazing the universe is… and how science can help explain things.
