Which spectacular supernova remnant is the product of an explosion witnessed in the year 1054?
Answer
Crab Nebula (M1)
The Crab Nebula, formally designated as M1 in the Messier Catalogue, represents the dramatic aftermath of a massive star ending its life in a catastrophic explosion known as a supernova. This particular event was not only observed cosmically but was also recorded historically on Earth. The text specifies that the cataclysmic explosion that created the Crab Nebula remnant was witnessed by observers in the year 1054. This makes the Crab Nebula a crucial object for studying both high-energy astrophysics and historical astronomical records, standing in contrast to objects like the Ring Nebula (M57), which is a planetary nebula remnant, not a supernova remnant.
