The Ring Nebula is perhaps one of the most photographed objects in the night sky, dating back to its first image in 1886. Its intrinsic structure has been debated for as long as it has been observed.

Planetary nebulae have been studied for centuries, but astronomers are getting new looks and a better understanding of the structures and compositions of these gaseous remnants of dying stars thanks ...

In the cold dark of the constellation Ophiuchus, a faint, wraithlike shell of gas is quietly advertising the fate that awaits our own Sun. Astronomers call it the Little Ghost Nebula, a planetary ...

An international team of astronomers have discovered two stars in a binary pair that complete an orbit around each other in a little over three hours, residing in the planetary nebula M3-1. Remarkably ...

Planetary nebulae represent a brief, yet illuminating, phase in the evolution of low- to intermediate-mass stars. These glowing shells of ionised gas are shed in the late stages of stellar development ...

The Butterfly Nebula is changing, and astronomers are puzzled as to why these changes are occurring. Observations of this planetary nebula show dramatic changes in the butterfly’s ‘wings’ in just 11 ...
