You and I collide 💫 Mounded, luminous clouds of gas and dust glow in this NASA Hubble image of a Herbig-Haro object known as HH 45. Herbig-Haro objects are a rarely seen type of nebula that occurs when hot gas ejected by a newborn star collides with the gas and dust around it at hundreds of miles per second, creating bright shock waves. HH 45 is located in the nebula NGC 1977, which itself is part of a complex of three nebulae called The Running Man. These three nebulae are reflection nebulae, which means that reflect light from nearby stars instead of emitting light on their own, like a streetlight illuminating fog. Credit: NASA, ESA, and J.
