The supernova remnant Simeis 147


This structure, also referred to in catalogs as Sh2-240, covers an area of ​​nearly 3 degrees on the sky (the equivalent of 6 full moons). The mentioned field corresponds to an actual diameter of about 150 light-years, since the debris cloud is at an estimated distance of 3000 years-light. The bright star that dominates the right side of the image is El Nath (Beta Tauri), located toward the boundary between the constellations of Bull (Taurus in Latin) and the Charioteer (Auriga in Latin), on a point of land almost exactly sky opposite to the galactic center.
