IC 4592, also known as the Blue Horsehead Nebula, is a stunning region of dust and gas located in the constellation Scorpius, about 4000 light-years away from Earth. The nebula gets its name from the shape of its central dark cloud, which appears to resemble the head of a horse. The blue color of the nebula comes from the reflection of light from nearby stars (Nu Scorpii) off of the dust particles in the cloud.
