GREAT high-resolution spectrum of [O I] emission at 63.2 microns (4.74 THz) toward the center of planetary nebula NGC 7027
Date
This high-resolution spectrum of neutral oxygen at 4.74 terahertz (63.2 microns) observed near the center of NGC 7027 shows several maxima and minima, showing that the expanding nebula has a complex structure with multiple components moving at different velocities.
