These stars may be young but they’re mighty. 💪

Sometimes, they expel narrow jets of highly charged gas at hundreds of miles per second. When these streams of gas collide with surrounding clouds of gas and dust, these energetic collisions create stunning objects like the one pictured, known as a Herbig-Haro object.

Herbig-Haro objects can be difficult to observe because their surrounding dust and gas absorb visible light. @NASAHubble Space Telescope’s Wide Field Camera 3 takes images at wavelengths outside a range detected by human eyes. Because of Hubble’s ability to observe at infrared wavelengths – where observations are not as affected by gas and dust – observing rare celestial phenomenon like Herbig-Haro objects is made possible!
