What Causes The Colors Of The Northern Lights Amazing Science Facts The northern lights are caused when charged particles from the sun collide with atoms of oxygen and nitrogen in our atmosphere. the colors of the aurora indicate how high up the collision occurred. red – 150 miles above earth. green – 100 miles above earth. violet – 60 miles above earth. blue – less than 60 miles above earth. Here we learn what causes the different colors in the aurora borealis (northern lights) and the aurora australis (southern lights). the science of the northern lights. the aurora zone. (n.d.).
What Causes The Colors Of The Northern Lights Amazing Science Facts Red [300 400 km (> 180 miles)]: red light at the top of an aurora comes from monatomic oxygen (o). at lower latitudes, sometimes only the red aurora appears, facing the north (northern hemisphere) or south (southern hemisphere). the other colors are below the horizon line. yellow green [100 300 km (60 180 mi)]: vivid lime green is the most. 7. cameras see it better. auroras are relatively dim, and the redder light is often at the limit of what human retinas can pick up. cameras, though, are often more sensitive, and with a long. The northern lights are created when energized particles from the sun slam into earth's upper atmosphere at speeds of up to 45 million mph (72 million kph), but our planet's magnetic field. Nothing can ruin our joy in the aurora borealis, or northern lights, those ribbons of blue, green and violet light that cascade from the sky.not even knowing for sure what causes them. physicists.
