A dying star can explode with the force of a few octillion nuclear bombs and create any element in the universe. But why do stars go supernova?
Type Ia supernovae work differently than all other types. A Type Ia supernova results from a white dwarf that's part of a binary system (that is, one that shares an orbit with another star) and was about twice the size of our sun during its life. This white dwarf's mass allows it...
Little did we know when we wrote "How a Supernova Explodes" forScientific Americanin 1985 that an explosion in the Large Magellanic Cloud, essentially in our galaxy, would go off only two years later, the first "nearby one" since Kepler's in 1604. On the whole, our theory worked out ...
When a massive star explodes as a supernova, it does more than release an extraordinary amount of energy. Supernovae explosions are responsible for creating some of the heavy elements, including iron, which is blasted out into space by the explosion. On Earth, there are two accumulations of ...
The initial radius of the shock implied that it was a blue supergiant that had exploded, but the lack of hydrogen emission lines in the supernova spectrum indicated a more compact star. The most likely scenario is that the shock ploughed into the massive stellar wind of a Wolf-Rayet ...
Is it a supernova? 是外星文明在打招呼吗? Is it on alien civilization saying hello? 你懂的,我们真的不知道 You know, we just dont know. 2017年8月,费米伽马射线望远镜 In August 2017, the Fermi Gamma-ray Telescope 探测到另一个短伽马射线暴 detected another short gamma-ray burst, 但这次与...
Rather, it’s a tool you can use alongside your existing content marketing processes. Google Search’s guidance on AI-generated states that they reward “high-quality content, however it is produced.” With that said, you can tell if something has been solely created with AI. Just like ...
We simulate the evolution of supernova remnants(SNRs) in a strong magnetic field. Usually,supernovae explode in a normal interstellar medium with magnetic field of no more than 50 μG, which has been well studied. However, the surrounding magnetic field will be much stronger in some situations...
It’s hard to convey how difficult it is to build the atoms that go into building people. The oxygen in the air you’re breathing right now has already had a hell of a life, born riding a supernova shock wave out of the core of a star and into interstellar space....
