Sig. gif?tid=2M68-7D-94-42-ABFD-18787 At the end of their lives, very massive stars explode in a supernova, which can be powerful enough to outshine the entire rest of thier host galaxy - around 5.0 × 1037 W. Suppose such a star is 950 times brighter than our Sun, which has a power of 4.0 × 1026 W, and suddenly goes supernova.

By what factor does the power of the massive star increase when it turns into a supernova?

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
