People with notably good imaginative and prescient have probably noticed it all through human historical past. Someday earlier than 1654, the early astronomer Giovanni Battista Hodierna seen M41 and positioned it in his catalog of comets and different celestial objects.

They’re unfastened collections of stars, situated within the flat disk of our Milky Means galaxy, born from a single cloud of gasoline and mud in area.
