What’s Hiding Inside The Crab Nebula?

The video explores the Crab Nebula, a remnant of a supernova observed in 1054 CE. Scientists have studied it across the electromagnetic spectrum, from visible light to gamma rays, revealing its complex structure and composition. Using various telescopes, they identified elements like helium and hydrogen, and discovered a pulsar at its center. The nebula's core is extremely hot, and its magnetic field traps energized electrons. The pulsar emits energy in the form of gamma rays, making the Crab Nebula a fascinating subject of astronomical research.
