This detailed image of the galaxies M81 and M82 reveals a potential new discovery: a faint stellar tidal stream to the left of M82. Captured with a total exposure time of 231 hours, this image showcases the intricate details and interactions within this galaxy pair.

The stellar tidal stream, a faint and newly observed feature, hints at the dynamic and tumultuous past of M82. These streams are often remnants of gravitational interactions and mergers, providing valuable insights into the evolutionary history of galaxies. The long exposure time has allowed for the delicate and faint structures to emerge, making this image a significant contribution to our understanding of these iconic galaxies.
