The elements on the visible part of distant stars can be obtained from the star spectra, that is, by analyzing the light that comes from the stars.
Scientists believe to have the sun to from from a bunch of gas and fire. They collided together forming this big ball of fire. More chemicals and gas get added everyday, but when there is to much it will soon explode sending fire every where in space and in the use to be solar system
Mars is a planet in our solar system. There is no life on Mars. It's half the size of earth It's the only planet that scientists believe supported life in the past

By the time our solar system was forming, all the naturally-occurring elements were present. After all, our Earth formed as part of the solar system, and all the elements we find here have been around for 4.5 billion years.
Scientists classify small objects in the solar system by size, shape, and composition
All of the planets in this solar system contain all of those elements, and it is quite likely that every planet throughout the galaxy is likely to contain all of these elements.

Scientists believe that the solar system formed about 4.5 billion years ago.
The big bang, a massive explosion creating all life as we know it.
SI system is used by scientists. It is one of the standard system adopted by scientists.
they believe our solar system was formed by the big bang
Eventually the sun will blow up and the solar system will be destroyed.
by a theory of the BIG BANG explosion and the HELIOCENTRIC theory,that until now is being believe
Scientists believe that the sun is around 4.6 billion years old. This age is determined through the study of the formation of the solar system, the analysis of age-dating techniques for rocks and meteorites, and the use of computer models.
Scientists believe that our solar system is about 2/3 of the way out along one of the spiral arms of the Milky Way galaxy.
The Sun and all the planets - our entire solar system - formed together, scientists believe, from a nebula - a spinning cloud of gas and dust - that condensed by gravity about 4.5 billion years ago.Some scientists also believe that some external shock wave, perhaps the explosion of a nearby supernova, may have caused the initial collapse of the dust cloud and started the formation. Because of the nature of the elements contained in the planets around the Sun, we know that the original nebula was at least partly made up of the remnants of other supernova explosions. Elements heavier than iron cannot be formed in fusion in normal stars; heavy elements like gold, lead and uranium can ONLY be created in the explosion of a supernova.
