Can we see shooting stars in the daytime?

The short answer

Shooting stars happen in the daytime too, but the sky is too bright to see most of them. Only very bright fireballs can sometimes be seen in daylight.

Space dust does not know whether it is day or night on Earth, so it hits our air all the time. In fact, there are just as many meteors in the daytime as at night. The problem is that the bright blue sky hides them.

Normal shooting stars are fainter than the sky in daytime, so our eyes cannot pick them out. However, now and then a very large piece of space rock makes a fireball so bright that it can be seen even in sunshine. The Chelyabinsk fireball over Russia in February 2013 happened in the morning and was brighter than the Sun for a moment. Daytime fireballs are rare and very exciting.

Scientists also have a clever way to detect daytime meteors: radio. When a meteor burns through the air, it leaves a trail of electrically charged gas that reflects radio waves. Using radio receivers, scientists, and even schools, can count meteors day and night, through clouds and in sunshine. This is how they discovered meteor showers that happen mainly in daylight, such as the Daytime Arietids in June.

So shooting stars never stop. We only see the night-time ones because the dark sky makes a perfect background.
