An astronomer, a cosmologist, a biologist, a chemist, a physicist In fact anyone interested in our existence Without supernovas, the world as we know it would not exist.
G40 is a supernova remnant. Particle physics is the study particles, radiation and matter. One would be able to study the properties of the G40 by applying the principles of particle physics
No, Mercury is too close to the sun and would be vaporized in the event of a supernova. The extreme heat and radiation from a supernova would completely destroy the planet.
Supernova 1987A was useful because it was the first opportunity for scientists to study a nearby supernova in great detail. It provided valuable insights into the late stages of stellar evolution and the physics of supernova explosions. The data collected from Supernova 1987A has been instrumental in advancing our understanding of the life cycle of massive stars and the formation of elements in the universe.
Tycho's supernova which he saw in Casseopia was important, as its suddenness and brightness caused him to study astromomy for the rest of his life. That resulted in many contributions to the modern understanding of stellar objects.
Me I would have to say supernova
A supernova is an exploding star. The Earth would be instantly incinerated, of course. There is approximately zero chance this will ever happen, though. If there was a supernova near Earth ... it would depend on how near. Betelgeuse is a good candidate for a supernova "soon" (within the next million years or so). Scientists who have modeled supernova explosions don't expect it will have much of an impact. If a star nearer than Betelgeuse were to go supernova, then it might be more serious.
your mom would be the correct answer.
we would explode and if there were survivors they would freeze to death
It would supernova.
Unfortunately not. We can tell which stars are likely to go Supernova, but our time frame is limited to hundreds if not, closer to thousands of years. Viewable supernova are rare and therefore we have not been able to study them sufficiently with modern instruments to gain an insight into their workings. As more and more supernova are observed our predictions could become better, but not for a long while.
Many people would have observed the Supernova, however it's discovery was attributed to Tycho Brahe. That's why it is called "Tycho's supernova".
They will end up as neutron stars or even black holes. Usually they will first explode as a supernova (of type1a).
