The Perseid meteor shower reaches its peak overnight on Aug. 12 and 13, unfortunately coinciding with this month’s full Sturgeon Moon.
Comets are remnants from the early days of the solar system, billions of years ago. Primarily made of ice and dust, these "dirty snowballs" orbit the sun and in habit the Oort cloud, an area in the outskirts of the solar system beyond Pluto. As comets approach the inner solar system, solar wind from the sun can sweep dust back into a long tail. When these comets are close enough to Earth, they can appear as dazzling objects in the night sky. Space probes from Earth have visited several comets to learn more about their composition.

The peak of the annual Perseid meteor shower shares the sky with August's full moon this week, meaning it will be difficult to view the iconic shooting stars.
