Why is there a star flashing red?
When the star is low in the night sky, the star’s light must travel through more of the Earth’s atmosphere to reach our eyes. The atmosphere refracts the star’s light, similar to how a crystal creates a rainbow effect with the sunlight. So we see Capella’s light as red and green flashes.

What do satellites look like in the night sky?

Are all red stars old?
As stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit. Thus, younger stars can appear bluer while older ones appear more red, and in this way, a star’s color can tell us something about that star’s age.
Do red stars emit red light?
On the other hand, cool stars emit most of their visible light energy at red wavelengths (with more radiation coming off in the infrared) (Table 1).
