- NASA shared a picture of clouds that showcasing the breathtaking view of Cavum clouds as seen from space.
- The Cavum clouds are also called hole-punch clouds or fallstreak holes.
- These odd cloud formations are caused by airplanes.
- Cavum clouds form when planes fly through banks of altocumulus clouds, mid-level clouds that have supercooled (below the freezing point of water but still liquid) water droplets.
- As air moves around the plane, a process called adiabatic expansion can make the droplets freeze into ice crystals.
- The ice crystals eventually grow heavy and fall out of the sky, leaving a hole in the cloud layer.
