To stand at the edge of an ocean is to face an eternity of waves and water, a shroud covering seven-tenths of the Earth. Hidden below are mountain ranges and canyons that rival anything on land.

New research, published today in Nature Astronomy, found that water may have formed in the first 200 million years of the universe's lifetime. The life-giving molecule may have been created so quickly ...

like water in a bow wave. This results in a shock wave of pressurized air molecules, which form a cone-shaped sheath around and behind the plane. This cone-shaped shock wave wouldn't be a problem ...

Dactyl clubs are hammer-like structures located on each side of a mantis shrimp’s body. They store energy in elastic ...

Such waves can be used to study materials and also to process them When an explosion or a projectile is directed against a solid, an intense wave of pressure and stress passes through it.

So the waves pile up against each other as they are created. These "piled up" waves are called shock waves. The greatest shock waves are at the tip and tail of the plane. This NASA photograph ...
