💫M81 and M82


M81 and M82



Among the many objects hosted by the Big Dipper, the duo formed by galaxies M81 and M82 is remarkable. The two objects are distant only from what is allowed to observe it together and appreciate their differences. M81 is an elliptical galaxy seen from three-quarters, vast, diffuse oval with a marked and almost punctual nucleus. As for M82, it is an irregular galaxy seen from the edge, smaller but contrasting and whose shape is reminiscent of what is happening.
