Egg Nebula: A Cosmic Blink From Red Giant to Planetary Nebula

Step inside the Egg Nebula—a fleeting moment in stellar life as a red giant sheds its skin and begins a new phase as a pre-planetary nebula. We unpack its striking bipolar geometry shaped by a hidden companion, the concentric shells carved by thermal pulses, and a polarization signature that reveals scattered light from the central star. Plus, how revised distances and the nebula's carbon-rich dust illuminate the galactic life-cycle—turning dying stars into seeds for new worlds.
