WebThe average star ‘lives’ for roughly 12 billion years. For average stars like the Sun, the process of ejecting its outer layers continues until the stellar core is exposed. A Stellar nebula is A nebula is an interstellar cloud in outer space that is made up of dust, hydrogen and helium gas, and plasma. WebScientists believe that the Solar System was formed when a cloud of gas and dust in space, made up of elements formed deep within stars, started to collapse, forming a solar nebula. This began to spin as it collapsed, eventually giving birth over billions of years to the Solar System as we know it today.
