When the fuel finally runs out entirely, the (by then) iron core collapses into a black hole or a neutron star. This halts the core's collapse, at least temporarily, and this process continues, over and over, with progressively heavier atomic nuclei. The temperatures and pressures become so high that the carbon in the star's core begins to fuse. An iron-core-collapse supernova occurs with massive stars (greater than 10 solar masses), which collapse so violently that it causes a huge, catastrophic explosion. There are two types of known supernova, depending on the mass of the original star. In the process it is teaching us about fundamental physics: how some neutron stars get made, how extreme stars live and die, and about how the elements we're made of get created and scattered around the universe." And it is helping us associate one thing we don't fully understand, the Crab Nebula, with another thing we have incredible modern records of, this supernova. ![]() "This supernova is literally helping us decode thousand-year-old records from cultures all over the world. 2021-22 Panini Chronicles Soccer Certified James Maddison Cracked Ice /23 11.05 21-22 Panini Photogenic Lebron James GOLD Unforgettable 1/10 RC 1,280.00 Lebron James 21-22 Gold Contenders Holo Finals Ticket 56/75 Lakers 35. “The term ‘Rosetta Stone’ is used too often as an analogy when we find a new astrophysical object, but in this case I think it is fitting,” said coauthor Andrew Howell of Las Cumbres Observatory (LCO).
