A supernova is the biggest explosion that humans have ever seen. Each blast is the extremely bright, super-powerful explosion of a star. One type of supernova is caused by the “last hurrah” of a dying massive star. This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot. Heat generates pressure, and the pressure created by

Ever wonder what happens in the aftermath of a supernova? In this video, you’re watching the glowing remnants of a stellar explosion 17,000 light-years from Earth disperse over a period of 25 years, making this Chandra X-ray Observatory’s longest-spanning video ever released. https://go.nasa.gov/3NaO7bO | NASA - National Aeronautics and Space Administration

A supernova explosion is one of the most powerful and awe-inspiring events in the universe. It occurs when a massive star exhausts its nuclear fuel, leading to a catastrophic collapse of its core. This collapse triggers a colossal explosion, releasing an immense amount of energy and outshining entire galaxies for a brief period. The explosion scatters elements like carbon, oxygen, and iron into space, seeding future stars, planets, and even life itself. In its wake, a supernova may leave behind

Scientists captured the explosive death of a star at the exact moment when the blast was breaking through its surface. | Interstellar Traveller
