The Mysterious Star Death

[00:00:00]A single supernova explosion can [music] outshine an entire galaxy of 100 billion stars for several weeks. Only stars at least eight times [music] the mass of our sun will end their lives in such a spectacular fashion. During this final [music] collapse, the core temperature can briefly reach 100 billion degrees Celsius, fusing elements heavier than iron.

[00:00:20]>> [music] >> The subsequent shockwave expands outwards at speeds exceeding 30,000 km per second, [music] ejecting most of the star's mass into space. The Crab Nebula, a famous supernova remnant, [music] was observed by Chinese astronomers in 1054 AD. This event released more energy in 10 seconds than [music] the sun will produce in its entire 10-billion-year lifespan. After such a cataclysm, [music] if the remaining core is between 1.4 and 2.8 solar masses, it collapses [music] into a neutron star, an object so dense that a single teaspoon of its material would weigh approximately 4 billion tons.
