A region left behind after a major star dies is called a supernova remnant. Supernova remnants are expanding shells of gas and dust that result from the explosive death of a massive star in a supernova event. They play a crucial role in enriching the interstellar medium with heavy elements and triggering new star formation.

When a star the size of our sun dies it will become?

When a star the size of our Sun dies, it will go through a series of stages, ultimately becoming a red giant and shedding its outer layers. This process will leave behind a dense core known as a white dwarf, which will gradually cool and fade over billions of years. The ejected outer layers will form a planetary nebula, enriching the surrounding space with elements that can contribute to the formation of new stars and planets.


What determines the way a massive star dies?

The way a massive star dies is determined by its mass. Stars with more than 8 times the mass of the Sun typically explode in a supernova, leaving behind a neutron star or black hole. Less massive stars, like the Sun, will eventually shed their outer layers to form a planetary nebula, leaving behind a white dwarf.


What does a star collapse into when its elements dies?

The elements do not die. The stars collapse into dense dwarf or neutron stars. But many explode as novae and the elements are scattered into space. This is the dust from which the next generation of planets are born.


How long does it take a space-ship to get to space?

A spacecraft can reach space in just a few minutes after launch, typically within 10-15 minutes. This can vary depending on the type of spacecraft, the launch vehicle used, and the speed of ascent. However, once a spacecraft reaches a certain altitude above Earth (commonly known as the Kármán line at 100 km), it is officially considered to have entered space.
