For years scientist have tried to explain what the universe is made of and they finally found the answer but the answer only make more questions about how it is made and what is its molecular structure. So they found out that it is made of dark matter. Dark matter is invisible and we only know it’s there because it has gravitation pull. Without it all the starts in the universe would just go off in different directions. The nature of dark matter is a mystery that when scientist investigated it only made more questions. A standard cosmological model of the universe shows that it is full of dark matter. Astronomers think that dark matter consists of cold which are exotic particles that clump together gravitationally. Over time the groups of dark matter grow and they attract normal matter which makes the galaxies we see today. Scientist use the highest tech computer to simulate dark matter and it show that it should all over the galaxy but in the middle there should be the most dark matter. Recent research from two dwarf galaxies shows that it is evenly places all over the space which is a big puzzle that they have to solve. They use dwarf galaxy for research because they are made up of 90% of dark matter and 10% of normal matter this makes them a great target for research. They have made lots of research and every day we find more and more information on what are they made of.

This is a good summary of the most important points from the article. This was a complex article to write about, but you got the main idea. It is clear. However, remember that all current events need to have a reflective paragraph as well as the link to the article in Science Daily. Who wrote the article? When was it written? This is all very important to include in order to reach higher achievement levels.
