The Fly and The Spider Nebulae

Entwined in the constellation Auriga, the Spider Nebula (IC 417) and its smaller companion, the Fly Nebula (NGC 1931), form a fascinating pair of emission nebulae approximately 10,000 light-years away. The Spider’s sprawling, web-like filaments are regions of active star formation, shaped by stellar winds and radiation from its young, massive stars. Nearby, the compact Fly Nebula glows brightly, its core a mix of reflection and emission nebulae surrounding a dense cluster of newborn stars.

Captured from Strakonice, Czech Republic, these nebulae present a stunning contrast: the Spider’s sprawling, diffuse arms versus the Fly’s bright, concentrated glow. Together, they illustrate the dynamic processes at work in stellar nurseries, where gravity and radiation sculpt the interstellar medium into these complex, ethereal forms. Despite the light pollution, their intricate beauty shines through as a testament to the creativity of the cosmos.
