Why are nebulae important?
Answers
Planetary nebulae are important objects in astronomy because they play a crucial role in the chemical evolution of the galaxy, returning material to the interstellar medium which has been enriched in heavy elements and other products of nucleosynthesis (such as carbon, nitrogen, oxygen and calcium).
they r essentially the birthplace of brand new star .
explanation:Nebula are enormous clouds of mostly hydrogen and helium . The gas slowly begins to collect and the gravity attracts more gas. Once enough mass has been reached , fusion begins and a brand new star is born . Planetary nebulae will often orbit the new star and the leftover gas and dust will likely for planets . Just like the way our solar system was born. This nebula is known as the "Pillars of Creation" . Incredible in size and potential to create many brand new star .
