About 2, massive stars in the centre of 30 Doradus produce intense radiation and powerful 'winds' of ejected material. X-rays are shown in blue, produced by superheated gases, resulting from supernova explosions and stellar winds. The multimillion-degree gas carves out giant bubbles in surrounding cooler gas and dust. When stars die and lose their mass, all the elements that had been generated inside are swept out into space.
Then the next generation of stars form from those elements, burn and are again swept out. The pillars pictured are five light years tall. The colours highlight emissions from several chemical elements. Oxygen emissions are blue and sulphur orange, and hydrogen and nitrogen appear green.
When you look at the stars through a telescope what you're seeing probably happened millions of years ago,' Ashley says. The other way to study the life cycle of stars is by finding samples of cosmic dust and observing them through an electron microscope. Invisible to the human eye, a single speck of this very pure, original stardust known as a pre-solar grains, because they are older than our Sun is only a few microns in size - times smaller than the width of a human hair.
Essentially, a scientist must take a tiny chip of a primitive meteorite and dissolve Things that are made at high temperatures in the atmosphere of stars are resistant to acid and therefore left behind. Most of the elements of our bodies were formed in stars over the course of billions of years and multiple star lifetimes. However, it's also possible that some of our hydrogen which makes up roughly 9. Weeping trees, teeth stronger than Kevlar and one of Earth's most spectacular natural events are all shaped by the Moon.
