Why Is the Sky Blue? | NASA Space Place – NASA Science for Kids Why Is the Sky Blue? The Short Answer: 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
Why Is the Sky Blue? | NASA Space Place – NASA Science for Kids En seguida nos damos cuenta de que el cielo es de color azul ¿Pero alguna vez te has preguntado por qué? Muchas otras personas inteligentes, también se lo han preguntado… ¡Y les ha tomado mucho tiempo averiguar cómo y por qué! La luz del Sol se ve blanca, pero en realidad está compuesta por todos los colores del arcoíris Cuando la luz blanca pasa por un prisma, queda separada en

Supermoon, Blood Moon, Blue Moon and Harvest Moon - NASA Space Place The air molecules from Earth's atmosphere scatter out most of the blue light The remaining light reflects onto the Moon's surface with a red glow, making the Moon appear red in the night sky The name "blood moon" is also sometimes used for a Moon that appears reddish because of dust, smoke or haze in the sky
What Is an Aurora? | NASA Space Place – NASA Science for Kids Oxygen gives off green and red light Nitrogen glows blue and purple These green bands of light in the winter sky above Alaska are an aurora borealis This is the name for an aurora in the Northern Hemisphere Credit: Sarah Histand Do other planets get auroras? They sure do! Auroras are not just something that happen on Earth
Explore the Electromagnetic Spectrum - NASA Space Place Credit: NASA JPL-Caltech Explore the "Magic Windows" of the electromagnetic spectrum below! Radio Waves Credit: NASA JPL-Caltech Radio waves are very long and not very energetic Radio waves can be from about the length of a football field up to 100 kilometers (60 miles) and more Here we see a quasar (for "quasi-stellar object") through the Magic Radio Window Quasars look a bit like stars
Troposphere | NASA Space Place – NASA Science for Kids The last 1% is made of argon, water vapor, and carbon dioxide When you feel the wind on your face, see clouds in the sky, and watch a bird flap its wings in flight, you’re experiencing the troposphere It’s a pretty nice layer to call home Visit other layers in Earth's atmosphere Go out to the stratosphere
