This Hubble Space Telescope image shows a bow shock around a very young star called LL Ori. Named for the crescent-shaped wave made by a ship as it moves through water, a bow shock can be created in ...

The phenomenon of stellar bow shocks arises when high-velocity stars, known as runaway stars, traverse the interstellar medium at supersonic speeds. As these stars emit powerful stellar winds, the ...

A cloud forms as this F/A-18 Hornet aircraft speeds up to supersonic speed. Aircraft flying this fast push air up to the very limits of its speed, forming what's called a bow shock in front of them.
