- The auroras are caused by charged subatomic particles (mostly electrons) smashing into Earth's atmosphere. These are emitted from the Sun all the time, but there are more during times of greater solar activity.

- Summary
When the lining in the back of your eye—called the retina—senses light, it sends messages to the optic nerve. The optic nerve then relays these messages to the brain, which identifies the image. When you are seeing stars or sparkles, something other than visible light is stimulating the retina. These false flashes are known as phosphenes. Phosphene...
When you see stars for a prolonged period or frequently, there are a number of possible causes. Here are some of the least serious explanations:
Sometimes a more serious condition can cause you to see stars. In such cases, photopsia may serve as a warning sign of a disease that has not yet been diagnosed.
The treatment of photopsia can vary based on what is causing it. In some cases, photopsia is treated directly; in others, treating the underlying cause will help clear the visual disturbances. Here are some examples: 1. Posterior vitreous detachment: No treatment is needed if the retina is undamaged. If the retina is damaged, laser therapy or cryop...
Seeing sparkles of light and similar visual disturbances is known as photopsia. The individual flashes of light are called phosphenes. Usually, seeing stars is due to temporary pressure on the eye. This is typically harmless and only lasts for a few seconds. However, if you see stars often or they last for a long time, see your provider. You may ne...

The Colour of Stars. Astronomy is full of colour references; white dwarfs, black holes and red giants for example. If you look up into the night sky you may be able to see a few thousand stars from a dark site. As the stars are all so distant they appear as points in the sky.
Why stars are different colours, red, blue and white, and how to see star colours more effectively when observing the night sky.
We can look up at a night sky and see the stars shining, but how do stars shine? Find out in our guide to the physics of starlight.
Jul 23, 2019 · Have you ever noticed how hard it is to see colour in the dark? That’s because only the rods work in low light. Scanning electron microscope image of the rods (long, skinny structures) and cones (short, wide structures) in the retina (Helga Kolb [CC BY-SA 4.0] via Wikimedia Commons ).
