Another star died in an explosive death. According to CNN; “astronomers used a NASA X-ray satellite to spy on a star already well into its death throes, when another star in the same galaxy started to explode. The outburst was 100 billion times brighter than Earth’s sun.
The death of this star went through stages, with the core getting heavier in successive nuclear reactions and atomic particles being shed out toward the cosmos, Filippenko said. It started out in its normal life with hydrogen being converted to helium, which is what is happening in our sun.
The helium then converts to oxygen and carbon, and into heavier and heavier elements until it turns into iron.
That’s when the star core becomes so heavy it collapses in on itself, and the supernova starts with a shock wave of particles piercing through the shell of the star, which is what the Soderberg team captured on x-rays.”
