👉 intersidereal is a term used in cosmology to refer to objects that are not directly visible or measurable from within our own solar system. These objects, also known as "phantom stars," were thought to be remnants of massive gas clouds or galaxies. They are believed to exist on the edge of our galaxy and have been observed by astronomers through telescopes and other instruments. The concept of intersidereal was first proposed in 1970 by astronomer Jean-Louis Chabrier
