Look at the image in the section "Galaxies: How They Look." Which detail from the article is MOST related to the image?
A. The Universe was formed by an event known as the Big Bang, a large explosion of matter. After the Big Bang, the universe was composed of radiation and free-floating subatomic particles.
B. Similarly, our solar system is one of many solar systems, and even our galaxy is just one of many galaxies. Scientists believe there are hundreds of billions of galaxies in the universe.
C. Like more than two-thirds of these known galaxies, the Milky Way has a spiral shape. A lot of energy gets generated at the center of the spiral.
D. Scientists believe that most of the dark matter in the universe is made of particles smaller than atoms. These particles are different from anything scientists have ever detected or studied so far. Previous​
