The dust grains are of no use dirty and pointless! That's what I had in mind when he saw the dust and then clean it? But in space, the powder is an essential ingredient in star formation.
Astronomers often talk about the stars like a giant ball of gas, but there is a lot of dust. Now, let's look at the photos on this page. This photo came from an area in space where the stars - a new star was born, and was known as the Carina Nebula. Orange part is the object that fills most of the region - and all this is dust!
Unlike gas particles, dust is not only used as fuel for energy stars. But, no dust, no star will be born. The stars can form only material Keika in the area of star formation is very tight. This is where the dust grains are very important contribution in the formation of a new star.
There are several areas in the Carina Nebula are tight enough to form new stars within a few million years. And massive stars are found in the nebula could help boost gas and gas particles to come together.
Winds of massive stars are found it will blow the material to meet - like leaves and trash blowing in the wind on a windy day. Also end the lives of massive stars in a powerful explosion known as a supernova explosion. During a supernova explosion, the material will get help immediately collected and new stars may be formed soon!
Interesting fact: the combined weight of gas and dust in the Carina Nebula range of 140,000 times the gift!
