People with notably good imaginative and prescient have probably noticed it all through human historical past.

M41 lies 2,300 light years away. The cluster – whose true diameter in area covers about 25 light-years – comprises about 100 stars together with a number of purple giants.
At mid-northern latitudes, Sirius and M41 keep out till roughly 4 a.m. native time at the moment of yr.
So get pleasure from Orion, the star Sirius and M41 on these January and February evenings. And by the best way, there are over 100 of the so-called Messier objects or M-objects to search out and revel in. Right now’s novice astronomers contemplate them among the many most prized objects to view by way of binoculars and small telescopes. Right here’s an inventory of M-objects.
