A supernova is the explosion of a massive star. There are many different types of supernovae, but they can be broadly separated into two main types: thermonuclear runaway or core-collapse. This first type happens in binary star systems where at least one star is a white dwarf, and they...
What is a supernova explosion? What is stellar astrophysics? What is thermonuclear astrophysics? What is theoretical astrophysics? What is the main difference between cosmology and astronomy? What are the odds of a second Big Bang? If so, when will it happen?
What is a supernova explosion? What kind of star is Proxima Centauri? What is COPUOS? What is Betelgeuse? What is a lunar meteorite? What is Arcturus? The North Star is in what constellation? What is a variable star? Which constellation has the fewest stars?
C. It is likely to end in a supernova explosion. D. It will gradually fade away and become a brown dwarf. 相关知识点: 试题来源: 解析 C。解析:参宿四(Betelgeuse)是一颗著名的红超巨星,红超巨星在其生命末期很可能会以超新星爆发的形式终结。选项A,白矮星通常是像太阳这样质量较小的恒星演化的...
The supernova was visible from Earth for four months, shining with the power of a hundred million Suns. There was so much debris that even the most powerful telescopes could not confirm what remained at its heart. 曾经长达四个月之久,人们可以在地球上看到这颗超新星,它发出的光芒亮度相当于一...

2. Why could telescopes not confirm what was at the supernova's heart initially? 3. True or False?A neutron star is made of the densest material in the Universe. 4. What are two reasons why the discovery is important? 答案 1. How long was the supernova visible for from Earth?
On February 23, 1987, they detected a supernova explosion in the Large Magellanic Cloud, a satellite galaxy of our own, about a million trillion miles away. Shortly after the supernova discovery, while delivering a guest lecture at a physics course for Caltech freshmen, Feynman said, “Tycho...
Now you know. A nova occurs when a dead star steals material from a binary companion, and undergoes a momentary return to the good old days of fusion. A Type Ia supernova is that final explosion when a white dwarf has gathered its last meal....
