What was the biggest explosion in the Universe?

The Universe, everywhere we look, is full of cataclysmic events and transient outbursts. <img alt="" src="https://miro.medium.com/v2/resize:fit:630/0*MNUKMxFAPF39UWKH" style="height:455px; width:700px" /> A combination of X-ray, optical, and infrared data reveal the central pulsar at the core of the Crab Nebula, including the winds and outflows that the pulsars care in the surrounding matter. The central bright purplish-white spot is, indeed, the Crab pulsar, which itself spins at about 30 times per second. The material shown here spans about 5 light-years in extent, originating from a star that went supernova about 1,000 years ago, teaching us that the typical speed of the ejecta is around 1,500 km/s. The total energy output of an event like this is approximately 10 billion times the present energy output of the Sun.
