About Local Bubble
Local Bubble is about 499 light-years from the Sun, so the light we see from it left about 499 years ago.
The map lists it as a galactic structure (structure) and shows it among the stars around the Sun, drawn on the plane of the Milky Way.
A cavity of hot, thin gas about 1,000 light-years across that surrounds the Sun, blown out by supernovae over the last ~15 million years. Drawn as a circle; the real shape is irregular (Zucker et al. 2022).

From Wikipedia
The Local Bubble, or Local Cavity, is a relative cavity in the interstellar medium (ISM) of the Orion Arm in the Milky Way. It contains the nearest stars and brown dwarfs and, among others, the Local Interstellar Cloud, the neighboring G-Cloud, the Ursa Major moving group, and the Hyades.
