What was the significance of linking the Crab Nebula to the supernova observed in 1054 C.E.?
It proved that all nebulae are formed from supernova explosions.
It showed that the Crab Nebula was formed by a collision of two stars rather than a supernova.
It was the first time an astronomical object was directly connected to a historically recorded supernova, confirming that stars can explode and leave behind nebulae.

What role does the pulsar at the center of the Crab Nebula play in shaping the nebula's appearance and energy output?
It absorbs energy from the nebula, causing the nebula to slowly fade away.
It is a black hole that pulls in surrounding gas, creating the nebula's shape.
It emits winds of charged particles that energize the nebula, causing it to glow and form complex structures.
