This structure change is triggered by a pump pulse (blue) and detected through X-ray scattering (yellow).

how does a spherical star create such intricate and delicate non-spherical structures?" In an attempt to find out, last year, Kastner and his colleagues used the Submillimeter Array (SMA) — a network ...

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.

confirms its ellipsoidal structure and provides a more detailed understanding of the velocities and locations of carbon monoxide molecules ejected by the dying star that generated the Ring Nebula ...

Previous theories suggested the nebula might be ring-shaped or resemble a soap bubble. However, the new model, based on SMA data, confirms its ellipsoidal structure and provides a more detailed ...
