Dangerous.

Novas, or supernovas. Tycho Brahe coined the phrase "nova stellarum" when a "new star" appeared in the night sky. We now know that he was observing a supernova, the death throes of a very massive star.

What are the answers to exploding sun challenge khan acedamy?

The Exploding Sun challenge on Khan Academy involves a series of interactive problems related to the physics of stars and energy. While I can't provide specific answers, the challenge typically focuses on concepts such as nuclear fusion, energy production in stars, and the life cycle of stars. To succeed, it's important to understand these concepts and apply them to the questions presented in the challenge.

Why are the stars in the globular clusters classified as population ll stars?

The first stars to form after the "Big Bang" were made just of Hydrogen and Helium. They were very large and died young, exploding to leave a little metal (heavier elements) in the universe - these stars are called "Population III" stars.The next stars to form incorporated a little metal from the older stars (but are still very low in heavy elements) and are called "Population II" stars. Stars in globular clusters are this sort of star (globular clusters are old and have not produced new stars for a long time). We can tell this form their metallicity and the Hertzsprung-Russell diagram for Globular clusters.Most stars contain a lot of heavy elements (high metallicity) and are quite young (like our Sun). These are called "Population I" stars.

If planets are formed by exploding stars and our star Sol is still here could we be a second generation solar system Sol II?

Planets are not formed by exploding stars!Planets are formed of the material left behind as a star forms from the dust and gasses of a collapsing molecular cloud.A distant exploding star may provide the initial compression wave that triggers the collapse of the molecular cloud leading to the formation of new stars and the planets around them. But there are other mechanisms having nothing to do with stars that might trigger this also.


Where did all the chemical elements in our solar system come from?

Mostly heavy elements are created inside stars and then spread when they go supernova and recondense into new stars and planets.


Where apart from air does elements come from?

The earth itself is the main source - ultimately everything but hydrogen came from exploding stars.


Where is the exploding star in the solar system?

There are no exploding stars (supernovae) in our solar system. Supernovae occur in distant parts of the galaxy, outside our solar system. The nearest known supernova to Earth was Supernova 1987A, which was located in the Large Magellanic Cloud, a satellite galaxy to our Milky Way.
