Hubble's Variable Nebula

Hubble's Variable Nebula (NGC 2261) is a glowing cloud of gas and dust in the constellation Orion, surrounding a young star. Its appearance changes over time because the dust scatters the star's light differently as it moves or as the dust alters position. This variability creates shifting shapes and brightness, making the nebula look as if it's "alive." The changes are caused by the star's energetic activity and the surrounding dust's movement, providing insight into star formation and the dynamic environment of stellar nurseries.
