- A NASA satellite snapped a photo of giant ring-shaped clouds over the Gulf of Mexico.
- You can see this phenomenon, called cavum clouds, from the ground and in space.
- Cavum clouds have a natural explanation but have been mistaken for aliens and other odd phenomena.
Earlier this year, NASA's Terra satellite was zipping over the Gulf of Mexico when one of its instruments snapped a photo of some odd-looking clouds.
The clouds looked like someone had taken a hole punch to the sky.
